Posted on November 23, 2017 at 00:43Hi,I have the SPC570S-DISP Evalution board which connect to my Windows 7 deskstop. Following the instructions from the ''PLS Debugger Installation driver on SPC560X Discovery board'' comes in the SPC5Studio software, installed FTDI driver, and 2 COM ports appears, using Putty connect to these 2 ports with 38400 bps, it gets nothing from the terminal.Is this expected or something wrong? The board is out of box without being reprogrammed. My board is SPC570S, but the instruction i could find is for SPC560X (wish i could find SPC570X documentation).Using import wizard imported the SPC570SXX_RLA SERIAL Test Application for discovery, i generated application and built, following the instruction from https://community.st.com/community/automotive-mcus-community/spc5-automotive-mcus/blog/2017/10/09/integrated-debugger-for-spc5studio  it failed on step 4 Flash and debug your application, My SPC5Studio has a ''Common task'' tab not the ''Activity Wi

The SPC58 targets a number of automotive applications including in-car gateways, firmware updates over-the-air, electric-vehicle battery management, lighting and body control units, and advanced parking applications. Premium vehicles today typically now have around 130 electronic control units (ECUs). These are networked to control about 150 motors and actuators.With this in mind the SPC58 line has been designed with scalable performance options, memory sizes, package options and a host of networking interfaces, all secured with the latest cryptog

Posted on November 10, 2017 at 08:56Hi,I want to use CTU in SPC56EC74 to trigger ADC conversions upon events generated by EMIOS Unified Channels running in OPWM mode. The ADC and EMIOS are configured and appear working, however CTU does not seem operational.As far as I understand the CTU has to be enabled by setting appropriate bit in ME_PCTL57. Quoting the xpc56ec.h:/* Note on PCTL registers: There are only some PCTL implemented in */ /* Bolero 3M. In order to make the PCTL easily addressable, these */ /* are defined as an array (ie ME.PCTL[x].R). This means you have */ /* to be careful when addressing these registers in order not to */ /* access a PCTL that is not implemented. Following are available: */ /* 104, 92, 91, 73, 72, 69, 68, 60, 57, 44, 33, 32, 24, 23, 21-16, 13-4*/union { /* Peripheral Control 0..143 (+0x00C0-0x0128) */ vuint8_t R; struct { vuint8_t :1; vuint8_t DBG_F:1; vuint8_t LP_CFG:3; vuint8_t RUN_CFG:3; } B; } PCTL[105];, which apparently means that register 57 is

Posted on November 09, 2017 at 02:11I downloaded the latest SPC5Studio version 5.5.  If I check for updates, it looks for http://spc5.drive.cloudforge.com/projects/spc5releases/spc5studio/updates5 which does not exist.  The root branches for SPC5Studio have source for 5.3.2, which leaves me thinking that this way of updating is deprecated?  Help>>>Check for Updates... gives error.  Anyone available for a retainer, week's worth of work from home to hold my hand a little, please contact me.

Posted on November 09, 2017 at 08:15I want to use EMIOS and PWM for SPC56EC74. When debugging the code for Channel 0, I can see that channel 9 is being initialized instead.Looking into the xpc56ec.h file, EMIOS section, the UCDIS Disable Channel Register is being described starting at (Base+0x000F), whereas in the datasheet it is said to be at (Base+0x000C).Is the xpc56ec.h header not compatible with SPC56EC74?The code: pwm_lld_init ();  pwm_lld_start (&PWMD1, &pwm_config_pwmcfg); pwm_lld_enable_channel (&PWMD1, 0, PWM_PERCENTAGE_TO_WIDTH(&PWMD1,5000));The header in question is taken from the following plugin:com.st.spc5.components.platform.spc56ecxx_rla_1.0.0.201707271939\component\lib\include\xpc56ec.hRegardsTim#emios #spc56xx

Posted on October 25, 2017 at 05:43Hello Team,This is Shivananda from Robert BOSCH. we are using  SPC584Cx/SPC58ECx 32-bit MCU family (Chorus 4M).we need to implement a feature when system in stanbymode, after 5 hours self wakeup of system should happen.Hope using Timer/Counter concept we need to achieve 5 hours count  and also using 'Smart Standby Wakeup unit� (SSWU) we can Wakeup the system.As per reference manual I have this informationIRCOSC is also the system clock available during the STANDBY and it is placed inSTANDBY power domain.Is it possible to implement this feature in Chorus4M???? if Pls can anyone help me in this to implement this feature.- I need Register details which are required to achieve this      1. How to run timer in stanbymode and which and how to enable clock to run the timer.      2. After 5 hrs. of time how can I wakeup the system( which registers need to program).Thanks and Regards,Shiva9739636666#

Posted on October 27, 2017 at 07:17Dear AllI am trying to generate the variable frequency PWM on SPC570s using Evaluation Board following the documents'SPC570Sx 32-bit Power Architecture�microcontroller for automotive ASILD applications'page 759 Usage of Compare RegistersI am using the dual compare registers COMP1 and COMP2 to generate variablefrequency PWM. I always get problems 'when changing COMP1 and COMP2 while the counter is active', the term Use caution when changing COMP1 and COMP2 while the counter is active. If the counter has already passed the new value, it will count to 0xFFFF or 0x0000, roll over, then begin counting toward the new value.The check is: CNTR = COMPx,not CNTR > COMP1 or CNTR < COMP2. That why I used CMPLD1 and CMPLD2 to pre-load the value of COMP1 and COMP2.The problem is whenever I use interrupt to change (update new) frequency by changing CMPLD1 and CMPLD2. Although at the beginning, the PWM looks good, however, th

Posted on October 22, 2017 at 00:36Hi,in the en.DM00293238.pdf document, CMPU and SMPU are shown for spc58ec80. Other documents relating to the e200z4d mentioned only MMU in core (no mpuwe instruction and mpu related registers shown) and only system MPU.Is it a (so detailed) document for comparison of the spc56ec and spc58ec internal features like MPU?Is it the same CMPU/SMPU in Chorus 4M like Chorus 6M ?Thanks!

Posted on October 03, 2017 at 19:25Hi I'm using the SPC560P40L1Im trying to switch a GPIO using pre-defined data stored in memory. I would like the GPIO to switch after a rising edge on a PWM pin which is being monitored by ETC/eTimer. I also need the DMA to control all of this. The CPU is pretty loaded already. Is there an example code I could use? Im using the SPC5studio and they only have examples of DMA use with SPI and ADC. I looked at the reference manual and that is not easy to start of with as a beginner to DMA  Can anyone point me in the right direction to get started?-Thanks

Posted on October 17, 2017 at 11:56I would like to add some source files to the source folder. the files name are :clock.c   and so on.but build faild.I know that this is a problem in the makefile, and SP5Studio provides  clock.c�?components.c .and My source files also have Clock.c and components.c...Causes the makefile rule to check for an error.I think you should develop an eclipse plugin，like this:In this case, the generated Makefile will not appear above the error

Posted on October 10, 2017 at 16:26Hello!I'm using XPC56xL minimodule on the XPC56XX motherboard.I slightly modified the SPC56ELxx OS-Less ADC Test Application to print the ADC conversion values on the UARTThe issue I noticed is that the value of the conversion is not stable: for example if I print 15 measures (all of them done without changing the trimmer position) I get the following result (in hexadecimal):ADC Value:278279274278277274272272275278276274276276278276So it seems that the 4 least significant bits are given only by the noise. Since i read on the reference manual that the ADC has 12 bits resolution, i would like to know if there is a strategy to keep those bits stable.Thank you in advance!kind regards,Fabio
