Hi,I'm trying to control a LTE module (sim7600e) using an AEK-MCU-C4MLT1 with a serial protocol (UART). The goal is to transmit a simple AT COMMAND, by following these simple steps:Receive "PB DONE" by the LTE moduleTransmit the AT commandReceive an "OK"I have built a simple state machine in order to follow these simple steps, and I attach the code at the bottom.I have done 3 tests to see if the code works properly:1st: Connecting the Chorus 4M to the pc, using a USB adapter, and testing the code with docklight, by sending the responses manually (PB DONE and OK). In this case the code works and it is possible to see that the code enters in all the states.2nd: By trying to execute the exact same code with a NUCLEO F446RET6 connected to the LTE module. The communication works perfectly, without a single error.3rd: By connecting the Chorus to the NUCLEO and using this one's UART to send the responses, also this approach works very well.Then I tried to connect the Chorus 4M

I am using SPC5 Studio, version: 6.0 with an SPC560B discovery board. The onboard MCU is the SPC560B54L5. According to the datasheet this has an onboard RTC.I created a new project using the 'Create new SPC5 application' wizard. This works fine and I can, for example, configure and enable the LinFlex and FlexCAN drivers as required, etc.For some reason, however, I can not enable the RTC driver. Specifically, when I open the configuration for the 'SPC560Bxx Low Level Drivers Components RLA' there is no option to enable / disable an RTC driver. Please see attached screenshot.I have studied some of the sample projects that come with SPC5 Studio for various other SPC5 discovery boards - and notice that these do allow the RTC driver to be enabled.I could try to copy and paste the RTC driver source files from one of the sample projects I referred to - but these are for different MCUs. And I shouldn't have to resort to this.Am I missing something?

Hi,In the osal.c line 389 "osalThreadGetMicroseconds" function uses "osalSysTime_ST2US" macro to convert ticks to microseconds.The macro uses osalsystime_t variable type that is 32-bit length. return ((uint32_t)((((osalsystime_t)ticks) * 1000000UL) / osal_ticks_per_sec));After 4294 microseconds, the value of the calculation overflows 32-bit and gives a wrong time. (4295 x 1000000 = 0x100007FC0 )I change to type to uint64_t and it's working now. return ((uint32_t)((((uint64_t)ticks) * 1000000UL) / osal_ticks_per_sec));

Is there any working example code of spc57 overlay ram?

I use a UDE STK .How do I check the value of a variable after creating a Braek Point ????​

I'm working in a project, OTA update via CAN using esp32 and SPC570S. According to the application note the codes were made in the host side. The bootloader was modified to accept CAN frame and the addresses were set according to the application note.host side - All the data sent and received are matched. (The screenshots are attached with this) SPC570S - No response can be observed. The bootloader not jumping to the application. also, the status LED is not blinking when CAN frames are received.How to solve this issue?

Hello allcurrently we are trying to configure eMIOS channel for SAIC/ IPWM mode. all configuration for channels are correct.eMIOS 0 CH 19 , Mode = 2, BSL - D bus.Clock for eMIOS module up. Other channels which are configured for O/P functionalities , counter are ticking for them.above channel which is configured for SAIC mode, BSL is selected but counter is not ticking.one example for eMIOS configured as SAIC/IPWM mode for SPC58EG will be really helpful.

We need your help regarding SPC58EG DMA configurations. We wanted configure DMA for DSPI communication.Below configurations are done in code , currently not working.eDMA_1 module , DMA channel – 12 (TX), 13 (RX), DMACHMUX_0 slot 6, 7 (as per below snap) , priorities for channels are set to 14Here , pls confirm if TX channel needs to have source ? as intention is RAM to DSPI PUSH transfer.To prove DMA module working we tried memory to memory transfer just to test DMA as below #define EDMA           (*( volatile struct EDMA_tag *)      0xF40A4000)void Test_dma(void){  EDMA.TCD[0].SADDR              = (unsigned32_t)&DMA_test_tx_data[0];;            EDMA.TCD[0].SIZE_MOD.R         = 0x0202;  

I am currently working on a project where I am using the serial communication. I am using an AEK-MCU-C4MLT1, with SPC5 studio on a windows PC. In particular, I am capable to transmit data but not to receive data. I tried also by enabling the interrupt, either for the transmission and the reception, and I found out that the program enters in the interrupt each time I call the function "sd_lld_read", even if I send no data externally (from docklight). By sending data from docklight, and looking at the rx_buffer I am not able to read anything.I attach the relevant part of the code here:int main(void) { /* Initialization of all the imported components in the order specified in the application wizard. The function is generated automatically.*/ componentsInit(); /* Uncomment the below routine to Enable Interrupts. */ irqIsrEnable(); sd_lld_start(&SD1,&serial_config_UART); sd_lld_read(&SD1, (uint8_t*)aux_rx, 1000); memset(aux_rx,0,sizeof(aux_rx)); /* Application main loop.*/ for (

I tried to initialize test channels on SARADC_B (supervisor)./* Channels Configurations (DMA is not used)*/ static channelConfig _saradcconf_ch_configs[SPC5_SARADC_MAX_NUMOFCHANNELS] = { {SARADC_CHANNEL_TEST, 96U,SARADC_REFERENCE_DEFAULT, SARADC_PRECHARGE_ENABLED, SARADC_CTR0, SARADC_WATCHDOG_REGISTER_NONE,NULL}, {SARADC_CHANNEL_TEST, 97U,SARADC_REFERENCE_DEFAULT, SARADC_PRECHARGE_ENABLED, SARADC_CTR0, SARADC_WATCHDOG_REGISTER_NONE,NULL}, {SARADC_CHANNEL_TEST, 98U,SARADC_REFERENCE_DEFAULT, SARADC_PRECHARGE_ENABLED, SARADC_CTR0, SARADC_WATCHDOG_REGISTER_NONE,NULL}, {SARADC_CHANNEL_TEST, 99U,SARADC_REFERENCE_DEFAULT, SARADC_PRECHARGE_ENABLED, SARADC_CTR0, SARADC_WATCHDOG_REGISTER_NONE,NULL}, {0U, 0U, 0U, 0U, 0U, 0xFFU, NULL}, /* Channel Configuration Unused 4 */ {0U, 0U, 0U, 0U, 0U, 0xFFU, NULL}, /* Channel Configuration Unused 5 */ };     /** * @brief Structure defining the configuration "saradcconf". */ SARADCConfig saradc_config_saradcconf = { /* conversion mode */

Hello,on SPC564B74 I want to read ADC0 channels 35 to 48, 51 to 54, 64, 72 and 80, and on ADC1 channels 0 to 15 and 32 to 38, so not consecutive channels.I started from the SPC56ECxx OS-Less ADC Test Application example in SPC5 studio 5.8.1.Each call to adcStartConversion to address a group are separated using a basic osalThreadSleepMilliseconds(100) but I always have one or more channels (usually the first of a group, ADC0 ch35 and adc1 ch0) that is correctly converted on the first call only (and remains to the same value. observed in pls udestk watch window).I also tried a system tick based method to separate conversions without success.Can I please get a explanation how to correctly organise the conversions (manual edma reconfiguration?). The DMA is configured in the generated code each time a conversion start is called so what is missing?The pin wizard and configuration are ok to me, see attached.int main(void) { /* Initialization of all the imported components in the order sp

Hi,Where can I get the EIRQ configuration for Stellar reference board? I'd like to config the GPIO button to receive interrupt. Thanks.

It is for the thermal validations so kindly provide the information as soon as possibleTJ-Junction TemperatureTC-Case temperatureTJ-C- Junction to Case temperatureThermal resistance

I'm working in a project of OTA update for the SPC570s MCU.I have modified the bootloader program to wait until CAN frames come. If there is not any CAN frame, the bootloader will execute the application code in the flash after a small delay. This is working for the application codes which are not having RTOS.

I use SPC5Studio-5.8.1, and SPC574S MCU, but I can not found any printf funciton example in the serial example code. Would you help me?

..

The bootloader is changed to wait for a time to check for CAN frames, otherwise it will give the execution to the application code. RTOS with 2 tasks are running, but not with 3 tasks.

Hi,I can't find any document that defines the Filter and Mask for FlexCAN, so I post a question about it. I think the filter only passes frames that contain exact ID as the ID in ID mask field. Am I right?Best regards Yuechuan Lin

I want to drive a mosfet. So that I need to know the current delivered by an I/O pin. I'm using SPC58EC80E5 controller. Electrical characteristics are mentioned in the document.

how to get access to secured spc5studio update site?
