Posted on March 26, 2015 at 10:17Hello, I would like to implement a SPI communication between an SPC560D and an SPC56EL Discovery Board. The SPC56EL should act as slave, the SPC560D as master. For both boards, I am using the corresponding DSPI example applications in SPC5Studio. Nevertheless, I am not able to get a communication between the two boards. The master sends every 20ms seven 12bit SPI frames to the slave. It was no problem to adapt the DSPI example for SPC560D to get this functionality. The problem is the slave (SPC56EL) configuration. I set the device in slave mode by adding the line spip->dspi->MCR.B.MSTR = 0 in the spi_lld_start function (spi_lld.c) and adapted the frame size in CTAR0 register. Additionally, DMA is set to RX only. After that, the SOUT pin from slave is set to high when master sets the CS to low. Nevertheless, the SPC56EL neither receives any data (DSPI_RXFR registers are empty) or sends data back to the master device What would be

Posted on March 17, 2015 at 16:11Hello,I am trying to use the serial driver for SPC560D30L3 device using Discovery kit (I have replaced SPC560D40 with SPC560D30 MCU). When I try to configure the 'Serial Driver Settings' for buffer size, it only accepts value of 16. Is it ok? As per HAL document, the default value is 16. What is the valid range for it? I tried entering values of 1, 2, 3 etc but it gives an error as incorrect value which prevents me from generating the application. What is the reason for the error? Any other settings required?Secondly, I am trying to read or write to the serial buffer/driver. I tried using functions 'sdGet' and 'sdPut' for reading / writing single byte to the serial. I am able to read the byte as it shows inside the watch window for SD1 but not able to transmit it back to terminal. Am I using correct function to achieve this? Any guidance/help will be highly appreciated.Thanks in advance.Mike. #serial

Posted on March 31, 2015 at 14:41Hi there,I have SPC5 studio installed and I updated all the components available (so my core and app wizard are 3.4.3). I am trying to run OS-less CAN test application from the wizard, having chosen the EVB I have (the SPC560BADAPT144S), and it won't compile out of the box.I get make: *** No rule to make target `all'. The standard thing to do in this case would be to have eclipse generate the Makefile it needs, but the option ''generate makefiles automatically'' is grayed out in the builder setting tab of C/C++ Build in the project properties.Any advice would be appreciated.

Posted on March 12, 2015 at 15:35Hello,I need a full documentation for the header I / O of this board (SPC560P - DISP). Is there? The manual on the site of St. explains only the configuration, but not their role. I need connect an LED to a breadboard and it flashes by writing C code on SPC5 studio.At the time I reached this configuration (attached) with the LED light is not flashing.Then, there are APIs for programming on this board. It is very complicated. Best regards Gianluca

Posted on April 13, 2015 at 11:42Hello,I am currently trying to set up the Watchdog on my SPC560B board.Firstly, after enabling the watchdog and letting it time-out into a reset, it then enters SAFE mode and does not reset the program. RGM.DERD is set to 0 so the watchdog time-out should just reset the program from what I understand?Also, when trying to use the interrupt-then-reset option, the triggered interrupt generates an SE_ILLEGAL and I'm not sure why that is? I have set up the interrupts correctly from what I can tell, setting them up in a similar way to ones I have previously done.Any help greatly appreciated, thanks. #spc560b-watchdog-issues

Posted on March 18, 2015 at 15:55Hello,I am trying to use the ADC driver (ADCD2) for SPC560D30L3 device using Discovery kit (I have replaced SPC560D40 with SPC560D30 MCU). I am trying to implement a state machine using different states of ADC driver. If my understanding is correct, I shall access the states as below,switch (ADCD2.state){case ADC_UNINIT:break;case ADC_STOP:break;case ADC_READY:break;case ADC_ACTIVE:break;case ADC_COMPLETE:break;case ADC_ERROR:break;}If above way is correct the statement 'ADCD2.state' itself is not working! Can anybody clarify the issue? What other settings are required?Thanks in advance for your help.Mike. #adc

Posted on April 25, 2015 at 13:58I am using test application for serial interface with SPC560D30. I used the application configuration - clock settings as 16MHz with the SPC discovery kit. Now keeping the test application same, I want to change the clock settings to 8MHz which the actual value I am using on my target hardware. When I do these changes using Application configuration and generate it, following errors are displayed (please find attached image also),In file included from ./components/portable_spc5_hal_component/lib/include/hal.h:32:0,                  from ./components/portable_spc5_hal_component/lib/src/hal_queues.c:38: ./components/spc560dxx_hal_drivers_component/lib/include/hal_lld.h:683:2: error: #error ''SPC5_FMPLL0_VCO_CLK outside acceptable range (SPC5_FMPLLVCO_MIN...SPC5_FMPLLVCO_MAX)''  In file included from ./components/portable_spc5_hal_component/lib/include/hal.h:32:0,       &

Posted on April 23, 2015 at 17:36Hi,I am writing a LINFLEX_0 driver for SPC560B60L3. DMA is not used as of now. All interrupts are disabled.Linflex_0 can be configured in 2 sets of port pins set 1: LIN0TX in PB[0] and LIN0RX in PB[1]. Alternate function in PB[0] is 3. set 2: LIN0TX in PB[2] and LIN0RX in PB[3]. Alternate function in PB[0] is 1.If i use set2 i could see the LIN signals in the lin bus. However if i use set1 i do not see any lin signal. I checked the microcontroller pins using oscilloscope and did not see any signal.I am writing the functions used as mentioned below.int main (void) {         __DI(); // Disable All interrupts         Disable_Watchdog();     MCU_Mode_Init();     MCU_PLL_Init();    /* RUN0 Module Config*/     ME.ME_RUN_MC[0].B.FXOSCON=1;     ME.ME_RUN_MC[0].B.FMPLLON=1;     ME.ME_RUN_MC[0].B.SYSCLK=4;  &

Posted on November 25, 2014 at 13:18Hello, Yesterday, I investigated a problem with my software project for an SPC560B. There are several calculations running on the controller and it additionally communicates over UART with a PC. When I tried to increase the UART baud rate, I got the effect that the controllers ''miss'' some bytes sent by the PC. I found out, that reason for that effekt has something to do with the UART RX interrupt and an interrupt created by the periodical timer PIT. After the PIT causes an interrupt, the UART RX can not trigger an interrupt. I always thought that a higher priority interrupt can break the program even when another lower prior interrupt is currently running? Best regards, Patrik

Posted on April 15, 2015 at 08:00I am using SPC5Studio with SPC560D MCU for a long time. From couple of days back, when I start the SPC5Studio application it asks for the login information (user name and password) for three different urls. Please find attached images for the same. This was not required earlier. What information is required to provide there? From where to get the user name and password? Has any one experienced this? Failure to login is preventing me from getting latest updates.Your earliest help in this regard will be highly appreciated. Thanks in advance.Mike. #login

Posted on April 17, 2015 at 10:55Hello,I am trying to execute a simple serial driver application on my target board. It uses SPC560D30L3 MCU. I have tested the same code using SPC Discovery kit (SPC560D30L3) mounted on it. The code executes successfully on Discovery kit but fails to execute on actual target hardware. When debugged, it displays following warning,''Warning, Core::PpcJtagTargIntf, Unknown break cause !!!''It hangs inside the function 'componentsinit' giving above warning. What could be wrong? Is any other configuration required for MCU or for debugger? I am using SPC5-UDESTK debugger here.Thanks in advance for your any help.Mike. #jtag

Posted on April 09, 2015 at 12:22I am using SPC560D-DIS Discovery board for development and SPC5 studio.I have imported test application 'SPC560Dxx OS-Less CAN Test Application for Discovery' for FlexCAN testing. In this FlexCAN0 is used in loop back mode. It is working in loop back mode. But after disabling loop back mode, it is not transmitting data on CANTx. The code for TX mailbox remain as 0x0C and error handler is generating. Error flags for TWRNINT, BIT0ERR, BOFFINT and ERRINT are set. I used below structure to transmit data, /* CAN TX Message structure */ txmsg.IDE = CAN_IDE_EXT; txmsg.RTR = CAN_RTR_DATA; txmsg.LENGTH = 8; txmsg.data32[0] = 0x55AA55AA; txmsg.data32[1] = 0x00FF00FF;And initialization routine is as below,  uint8_t mb_index = 0;  uint8_t id = 0;  /* Entering initialization mode. */  canp->state = CAN_STARTING;  /* Clock activation.*/#if SPC5_CAN_USE_FLEXCAN0  /* Set peripheral clock mode.*/  if(&CAND1 == canp) {

Posted on April 08, 2015 at 09:33Hi there,I am trying to run a test application (SPC560Bxx OS-Less test application) on SPC560B60L5 mounted in SPC560BADAPT144S evaluation board, using SPC5-UDESTK.After generating and building the test application I am trying to connect by pressing hte debug button, but it says that launch failed, binary not found.After creating a ''C/C++ Application'' debug configuration and pointing it at the out.elf file in the build directory, I am still failing to connect with the error:Error while launching command: gdb --version.Is there anything missing in my SPC5 installation? Also, could someone point me at a step by step tutorial application notes? I was unable to find one in ST's site.Thanks in advance.

Posted on April 06, 2015 at 12:56Hello Members,I am trying to purchase 10 SPC560D40L3 MCU for building my product prototype. I tried placing the order with ST. I was directed to ST vendor. Even after accepting a lead time of 24 weeks, I am unable to get any clear communication from either ST or vendor for the arrival of the MCU devices. Has anyone tried to buy this or any other SPC560 MCU? What is your experience? I am worried for the production time because if the MCUs are not getting available on time, this may hamper my product launch.I even tried to book few samples for this MCU but there also no clear communication from ST and hence decided to go for purchase.Has anyone experienced similar for SPC560 series MCU? Any suggestion or help in this regard will be highly appreciated.Thanks.Mike. #spc560-mcu

Posted on April 03, 2015 at 16:34Hello,I am trying to use flash driver from Application Configuration for SPC560D40L3 device. I used an example from SPC560B series available with SPC5Studio. I modified the platform settings to use SPC560D40L3 device, modified the flash address and page settings as per new device and tested the application using SPC Discovery kit (it has SPC560D40L3 mounted on it replacing the SPC560D40L1). Now I created a new application by adding the flash driver from availble components for SPC560D series. With same code files, as above example, when I try to build the application it gives an error for 'FlashMap.h' module. When compared, the two header files - one with new flash driver and the older with SPC560B device are not matching. I am attaching both files here. Is it correct or with v3.4.3 release, it has also changed?The error is for line 'void ErrorTrap(UINT32 returnCode);' saying that unknown type name 'UINT32'. Is any other header file required?

Posted on March 19, 2015 at 11:59I have configured few interrupts using Application Configuration -> ISRs (under SPC OSAL Component). I have multiple header files which I supplied to the 'Headers' parameter under 'ISRs'. I have provided 4 different header files. For another interrupt, I want one more header file. When I try to add one more file i.e. 5th one, the SPC5Studio IDE hangs (initially shows busy but later changes to 'not responding' and can not be exited). Is ther limit for no of header files for ISRs? Why is this issue?Thanks.Mike. #interrupts---headers

Posted on March 25, 2015 at 17:45Hello,i'm trying to send UART frame using DMA.==> the problem is that the last bytes in the UART fifo not sended. and when i send the next frame i receive the last byte of the old frame. is there any mothod to clear the UART fifo before starting DMA transfer ???why the last bytes in the fifo not sended ? 

Posted on January 29, 2015 at 13:56HiSection 6.1.1 of the SPC560x Reference Manual says that ''in order to successfully boot from flash memory, you must program two 32-bit fields into one of 5 possible boot blocks.''I have written 0x005A005A to address 0x00000000 accordingly (on our SPC56B Discovery Kit) but neglected to program a valid 32-bit reset vector. Now the board is stuck in reset (I can't even connect the JTAG probe).Is there any way of resolving this? Not just to ''unbrick'' the development hardware but if this were to happen ''in the field''.ThanksKevin

Posted on March 22, 2015 at 07:52I'm having problems getting the demo code to successfully RX on FlexCAN0 and then TX on FlexCAN1 (and vice versa). canReceive() detects the new message and returns MSG_OK when using a breakpoint in canlld_receive() and stepping code. Then canTransmit() loads the TX mailbox on the other CAN with the received CAN ID and data. However, the code never seems to trigger a breakpoint when checking for MSG_OK in main(). (Demo code cut from one of the OS-less CAN demo's. Data is being received as I am successfully seeing it when copied to the periodic TX I also have running. SOmetimes the TX from the RX can be seem, but it only comes out with the periodic TX. Any ideas: - RX not returning MSG_OK (corrupted) when running in realtime? - What might delay TX until another TX? I believe double checked PADSEL, etc are OK. Note: I also found that USB only connection only puts out 3.3V on 5V. You need to use the 12V input if you are attaching CAN tr
