Dear Community member, I am going through example code given in Autodevkit for SPC5 mcu with AEK-POW-BMS63EN ic.Here I am unable to find at what voltage differences between cells, balancing is being enable ?during execution, as seen watch view balancing is being halted for some time while the voltage is still high compare to other cells ?  Regards,bitBuddy

How to read ADC conversion results on the GTM/MCS.Here is my code:MCS side:AN8  = __brd(0x00005440);AN9  = __brd(0x0000544C);AN16 = __brd(0x00005480);AN17 = __brd(0x00005488);AN26 = __brd(0x000054D0);AN27 = __brd(0x000054D8);AN40 = __brd(0x00005540);AN41 = __brd(0x00005548); CPU side:GTMINT.EXT_ADC_SEL.B.MCS_ADC_SEL_EN = 0; GTMINT.EXT_ADC_SEL.B.MCS0_ADC_SEL= 0; GTMINT.EXT_ADC_SEL.B.MCS0_ADC_SEL= 1;GTMINT.EXT_ADC_SEL.B.MCS0_ADC_SEL= 2;GTMINT.EXT_ADC_SEL.B.MCS0_ADC_SEL= 3;GTMINT.EXT_ADC_SEL.B.MCS_ADC_SEL_EN = 1;while(GTMINT.EXT_ADC_SEL.B.MCS_ADC_EN_ACK == 0){ } 

I want to read and write data by serial connection.For test, I import samples "SPC58ECxx_RLA SERIAL Test Application for Discovery" from application library.In my understanding, the "main.c" function write "Hello World!" by serial connection.my environmentRS232 connection (PC to SPC58EC_DISP)puttyWhen I flash the code to my board, the putty write "cRK".I cannot understand why my pc receive "cRK".I think my pc receive the "Hello World".please help!!

Hi I have connected the GNSS1A1 board and F446ZE boards. When I run the FW (Virtual Com Port) that I set up through STM32CUBE IDE (X-CUBE-GNSS) and start the program, when it enters MX_GNSS_Process() the gnssMsg struct's buffer pointer is pointing at reserved 0x2002 0000 address. Then I tried generating the code for FW Updater example program, the Teseo Suit Can not do anything. It stops at Syncing, or if I try to force the update, at around 80% it freezes and recommends recovery mode. That doesn't work either. Please help. I tried everything I2C or UART port but it looks like nothing is helping. The GetPos example is running fine, however gets no data. @Tesla DeLorean maybe you know something. :)

Hi,I am using:Processor: SPC58NE84C3Compiler: FreeGCCWe have a working software setup running with optimization level "O0". However, when we enable "O1", we encounter issues in certain states where it triggers the the Machine Check Interrupt (offset 0x10), causing my callback function, void ivor1_callback(uint32_t Xsrr0, uint32_t Xsrr1), to be called.I would like to further investigate the source of the Machine Check Interrupt. According to the datasheet, I should check the MSR and MSCR registers.In my case, both registers hold the value 0x00000000.Could someone help me identify the source of the Machine Check Interrupt?Best regards,Felix 

I am using sample example from SPC58NN84E7, I could see there is common ISR function for all the modules, of course with different vector number, But i am not able to see how this   #define IRQ_HANDLER(id) void id(void) function address is registered to the respective interrupts.  could some one help me ? Thanks in advance

Hello,I have a question regarding the L9800 product (LS driver). The value of the CFG_2.FR_ADJ bit in "Table 12. Coefficient overview" differs from the value of the CFG_2.FR_ADJ bit in "Table 18. Register addressing space" in the datasheet. Could you please clarify which value is correct? * Table 12. Coefficient overview * Table 18. Register addressing space Thank you.

Hello team,I am currently working on configuring the GPT (General Purpose Timer) MCAL module for the SPC58NN84 microcontroller. While I have successfully configured PIT channels 0 and 1 for my project, I am encountering an error related to RTC (Real-Time Clock) channels during compilation.Error Message: In file included from C:/STMicroelectronics/SPC58XE-Nxx_MCAL40_101_Signed/Gpt_TS_T2D42M10I1R0/src/Gpt_NonASR.c:79:0:C:/STMicroelectronics/SPC58XE-Nxx_MCAL40_101_Signed/Gpt_TS_T2D42M10I1R0/include/Gpt_LLD.h:386:52: error: 'GPT_RTC_CHAN_NUM' undeclared here (not in a function)extern VAR(uint8, GPT_VAR) GPT_LLD_RTC_HardwareMap[GPT_RTC_CHAN_NUM];Findings:No RTC channelUpon investigation, I found that the SPC58NN84 microcontroller does not have an RTC channel available for configuration.

I have successfully established a connection between SPC584B and UDE STK2 as shown below: Mo 07.10.2024 14:58:50.425, Success, Core2, UDEDebugServer, Connection to SPC584B70 target established: PowerPC Target, JTAG-ID: [32bit JTAG ID] In the UDE STK menu, under Config -> Target interface... -> xPC56x/xPC57 Options, when I changed the 256-bit password for Censorship unlocking from the default value to all 0xFF, I was still able to connect via JTAG. Therefore, I believe that the JTAG password lock is not activated.According to the RM0449 Reference Manual, it seems that I need to set the DBL bit of LOCK3_PGn to 1 to enable the JTAG password lock. However, I do not know the address of LOCK3_PGn. Also, how can I modify the DBL bit of LOCK3_PGn?

Hi, I'm using the SPC58NN84E7 controller for CAN communication. I have referred the this application note that has a similar implementation for SPC58ECx controller. I have configured M_CAN_2_SUB_0 hardware channel for CAN communication with a baudrate of 500kbps.After I write to the TX buffers i.e M_CAN_2_SUB_0_TX_BUFFER_0_T0, T2, T3 & T4, a bit to the corresponding TX_BAR (Buffer Add Request Register) is set. Later in the M_CAN_2_SUB_0_TXBRP (Tx Buffer Request pending register), the corresponding buffer bit is set.Currently I have set only one data byte (0x55) to TX over CAN.The transmission status stays in pending throughout multiple iterations : The corresponding bits in the TXBTO(TX buffer transmission occurred register) are never set. I have configured Dedicated TX mode.What configurations am I missing here?

Hello All, I am working on data storage on external flash memory, so for my application we are using SPC582Bxx MCU and W25QXX as external flash to store audio files into it. I have configured the below SPI pins to access the flash memory device, I have referred the sample DSPI code, with reference this sample code, i made the required changes to access the flash device. But unfortunately, I am unable to get data from the device. I am trying to read manufacture data of flash device first then writing operation. Configuration, as per the pin mapping above, we get the DSPI3 configuration. I am attaching the simple code that written to access the flash device. I am struggling to find the way to access, please if anyone know about the configuration to access device please do share the steps in details. I am also attaching the datasheet of flash device. Kindly let me know, how to access the DSPI3 in auto devkit studio.Thank you in advance, Regards,Rohit R

Hi,The screenshot below is from the L9963E datasheet DS13636, page 125. Is the description for VTREF_BIST_FAIL here a typo?It matches exactly the description of a the VCOM_COMP_BIST_FAIL bit in the BIST_COMP register, which makes more sense. I note there is also a VTREF_COMP_BIST_FAIL bit in the BIST_COMP register, how does VTREF_BIST_FAIL compare to this flag?I can't find any other references to VTREF_BIST_FAIL in the rest of the datasheet.Best, Jack

Hi, I bought a TESEO VIC3DA from MIKROE some time ago. I am addressing it via UART. I am receiving RX data, but it is always the same. The same location is always returned. I can also see in the frame that I have 0 satellites. However, I had the hardware near the window. But no new data is being delivered, and no new satellites are being detected.

The STM distributor is trying to locate the EV-SPC582B programmed with a dedicated firmware but no luck yet. Does the new AutodevKit system have any firmware for the SPC582B_DISC eval PCB? 

Hi everyone,I'm working with the SPC58NN84E7 in SPC5Studio, and the same issue occurs in the AutoDevKit Ecosystem. Simple examples, like controlling an LED with this processor, work without any problems. However, as soon as I add the GTM library, the program freezes during gtminit() at gtm_aux_in_src();. I’m not configuring anything in GTM.Has anyone encountered this issue? Could anyone please help?

Hello all,A very good morning, I hope you all have the good day.I am developing the AVAS project taking the base code(shown in the snippet) from the AutoDevKit.Here my requirement is I need to increase the sound from speed 0 to 20kmph and sound should decrease from 21 to 30kmph. For this requirement I need to increase and decrease the sound gradually. Initially I was using playsound() API where gain is fixed so I was not able to increase or decrease the sound. Now I am using playsoundwithgain() API, where I am changing the gain with respect to the speed this is affecting the quality of sound and I am getting so much of noise.So I wanted to know1. How to increase and decrease the sound linearly which API I need to use?.2. Which parameter should be varied with respect to speed whether volume or gain or something something else has to be done.It will be very useful to me if I get suggestions on my issues.Thanks & Regards,Aishwarya UM

Hi,I have recently started working with AutoDevKitStudio and tried some of the example codes. When I wanted to modify example code and add more pins in Pin Map editor, after saving my changes and generating them I couldn't see newly defined ports in autogenerated components\spc58ecxx_board_initialization_component_rla\cfg\board.h file.I'm using AutoDevKitStudio 2.4.0 and as said I'm pretty unexperienced with it. I followed YouTube tutorial and official documentation but I still can't see my newly added pins. The same happens if I try to modify some parameters of the components defined in example. After saving and doing full build again, i can't see my changes in generated code. Am I missing some steps here? BR,MaraLo

Hello ST Community, I am currently working with the SPC58NN84E7 controller and using the AUTOSAR SPC58NN MCAL version 4.0.3.I am in the process of configuring the PWM module for our project, which requires both the GTM (for clocking the counter) and the DTM (for dead time functionality).However, I have noticed that the AUTOSAR SPC58NN MCAL version 4.0.3 does not provide  DTM module to implement dead time functionality. Could anyone provide guidance on how to handle this limitation? Are there any workarounds or alternative solutions available for implementing dead time in this context? Thank you for your assistance!Best regardsVeer.

Hello everyone,I’m currently working on a project using the SPC584B70E1 chip and SPC5Studio as my development environment. However, I’ve run into an issue where the “Execute” and “Debug” buttons are grayed out, and I’m not sure how to proceed. After searching online, I found information about the SPC5-UDESTK, which seems to be a USB/JTAG debugger for SPC5 MCUs. I have a few questions about this:Is it absolutely necessary to purchase the SPC5-UDESTK to enable debugging, or is it possible to use a standard ST-Link for debugging with SPC5Studio?If I do need to purchase the SPC5-UDESTK, will I also need to buy any additional debugging software, or is it included?Are there any free options available for debugging? If using ST-Link is an option, could someone explain how I can set it up for debugging in SPC5Studio?I would really appreciate any advice or guidance on this matter. Thank you so much for your help!
