Automotive and Transportation

Im interested in getting advanced design of Battery Management system for EVs using L9963

I wonder if there is any ST solution on charging a batterypack that already uses the BMS63EN? So that these two could work together in terms of powercontrol. Or is it maybe easier to implement than I think? 

I am looking for an onboarding on the Autodevkit intended RTOS. Which is it? I am a bit confused, Chibi or FreeRTOS? And how do I set it up? Maybe there is a walk through AN/UM available? 

Question 1: When I make the mcanconf like described in AN the second mcanconf is named exact the same, it does not autoincrement to mcanconf1 as it is in the example. Is that important? Or how/when do I link a certain mcanconf to a subsystem? They must be linked somehow, or? (My mcanconf1 also does not work when I set it up myself, that's why I ask) Question 2: The code looks like this:returnvalue = can_lld_transmit(&CAND2, CAN_ANY_TXBUFFER, &txf);osalThreadDelayMilliseconds(1); if (returnvalue != CAN_MSG_OK) { for (;;) { } }So if I have a error on my CAN transmission the program will be endlessly trapped in the for loop?Isn´t the automatic resending of invalid frames/messages handled by the transceiver? Or does it have to be taken care of here in the sending call? Or is this just an example for loop that should throw an error? -> I thought of handling that one with the error callback.  Question 3: Maybe the answer is already in Q2 but, hav

Hi everyone!My disappointment has reached the level where I write about it. Mostly to find a way to navigate the  ecosystem or to find an alternative. My initial idea was to move from Atmel 8-bits towards something more powerful. Usecase is automotive, where normal STMs are not at home. But..there was this new thing: SPC5. It took me days to figure out that the install videos where outdated and SPC5 Studio is not needed for Auto dev kit anymore. Several installations later I was able to click my way half through it but was totally stuck with UDE and the concept of it being something 3rd party that was no part of the IDE. Entering the pitfalls of eclipse (man what is this? Its awfully cluttered, buggy and inconvenient) I spend a few days learning that the pinmap editor must be closed in order to generate proper code, that the dark mode does not work -no matter what I try. The documentation is everywhere and nowhere. Is it in the devboard description? Or maybe some ot

The examples are a great resource to get started. But it looks like when making changes to an example it does not only safe in the working folder. It also safes (or changes) the original. After playing a lot with one example I wanted to just delete it from my working folder and import a new fresh one, unchanged. I thought thats why there is an import function for examples, right? But- it is not the original anymore, it always shows my changes after importing a new one. So- if I dont want a complete reinstall of the whole devkit- any ideas where I can find the examples for download and fresh install? 

Hi,I'm looking for C Software library for Battery Management System ST L9963.My setup:IDE: SPC5StudioMCU: SPC570SxxPlease, where can I find this library?ThanksLeo

We have a BMS board with SPC574S64 Controller and L9963E as BMS ICI am trying to communicate with the BMS IC via Direct/Normal SPI modeI have done the necessary HW connections properly and ensured the SPI lines are proper.I am trying to communicate with the L9963E but I donot see any response from it, some time I see all response as FF or 00once in a while I saw a frame on the data bus as 0x0000000016 which is a wakeup frame, but I am not sure what is missing for the chip to respond, here are the command sequence I send on the Bus as per the data sheetI have only one BMS IC for now on the board which is connected to the SPC574S64 via direct SPI linesBroad Cast frame to 0xC0040C1040500us delayRead back frame 0x8286000000I am not seeing any response from the L9963E.even I tried sending the rest of the frames on the bus, but still no responseI have seen once there is a response of 0x00000016 - default wakeup frame, but later I didn't see any responsePlease let me know if any worked on thi

We have a BMS board with SPC574S64 Controller and L9963E as BMS ICI am trying to communicate with the BMS IC via Direct/Normal SPI modeI have done the necessary HW connections properly and ensured the SPI lines are proper.Now I have a question:1. the SPC574S64 controller is Big endian and the L9963E is little endian as per the data sheets registers how they were representedI have captured the SPI sequence via logic analyzer, I am trying to send the broad cast frame with data as 0xC0040C1040           C0 04 0C 10 40Byte    4    3    2   1   0As the LSB [40] shall be the first/zero th  byte on the bus and MSB [C0] shall be the last one to go the busThis is how the data looks on the busPlease let me know if this understanding and observations are correct as per the endianness of both the controllers    

HiI am trying to configure SPI communication between L9963E and SPC574S64E3I referred the DSPI example in the latest SPC5StudioI could see the baud rate is configured to 1Mbps, 16kb and 26kb But as per the L9963E Spec the baud rate is either 333kbps or 2.5MbpsI tried with all the baud rate prescalars I could see more than 1.5Mbps​KIndly suggest, how to configure for L9963E chipset​Thank you for your support​

I needed info on CRC calculation as well.

Hi,I am trying to communicate with BMS IC on our developed board and I donot see the communication happening with BMS IC despite of following all the instructions I have a L9963E BMS Eval board for reference,I have tapped out the SPI frames on the bus to see the dataI could see for the 5 byte of frame data 4 bytes are going first and 2 byte is going after a delay of around 2.2 us when I have fed the SPI  API spi_lld_exchange with 5 bytes the data goes out in one after the other continouslyIs there any specific reason why the data is send in this way?I do not see any specific section mentioning any where in L9963E data sheet regarding this?Kindly let me know what could be the reason for this do I need to send the data in this way?Also I could see the clock frequency is varying in between 8MHz and 12MHz if see the clock in the image it is not pulsated at same frequency  

I uninstalled my prior Autodevkit 2.1 which seemed to had a lot of trouble with my workspace. The new 2.2 looked promising. A minor bug is that it still shows 2.1 in the About/help section as in the release notes, as on the linked website of the release notes.  But most disturbing: I miss my examples from the application library! If I choose AEK-MCU-C2MLIT1 or SPC58EC I cant see any CAN example. Even if i filter for CAN I get some results of which some dont even contain any CAN. The RLA CAN Test Application for discovery is gone (I used it on 2.1), I can find it when I select SPC58x Gxx - which does not work (UDE can´t get contact and load this onto the board) I also can´t find a example update function or release note what the examples are doing in particular or which UM/release note may walk me through them. How is the usage intended? 

I need to receive CAN ids of more than 8 extended frames, the current method using RxFIFO can only receive up to 8.Reference manual indicate that Powerful Rx FIFO ID filtering, capable of matching incoming IDs against either 8 extended, 16 standard, or 32 partial (8-bit) IDs, with individual masking capability.The CAN RxFIFO configured by SPC5Studio CAN only receive 8 CAN ids at most. Is there any way to receive more CAN ids? Thank you in advance！ 

Hi, I just moved from stm32 with Cube IDE into AutoDevKit with an AEK-MCU-C4MLIT1 discovery board. I am so frustrated after a complete 8 hour spin and still no results. Why is AutoDevKit called an IDE when the Debugger is still external? I dont get it. I tried to get it running and found posts heer, 3 years old already stating that the eclipse integration tool does not work anymore. I run into trouble with the external UDE debugger as well, plenty of them. Is there an IDE as CUBE where I can get everything for the SPC controllers? Is there an explanation and code example of simple things like blinking LEDs, hello word kind of things? Or is there a way to run SPC58 in CubeIDE? Tips, suggestions?  

Hello,I am working with lin sample driver application. I am able to send and receive data but in between lin i am getting the following errorsync errorrcv error due to invalid headerframing errorshort response invalid checksumI have done the testing with canoe by keeping spc560b in master mode . i am attaching the screen shot, how can i resolve these errors?Thank you

Hi team,    I already have this module-Teseo-LIV3F( https://estore.st.com/en/evb-liv3f-cpn.html ) But i need communicat the L5 band NAVIC signal. In this module not supported the L5 NAVIC signal.In this module-Teseo-LIV3F( https://estore.st.com/en/evb-liv3f-cpn.html )  replace the L5 NAVIC supported ic a Teseo-LIV4F(https://estore.st.com/en/teseo-liv4ftr-cpn.html)This is supported or Not???Thanks and RegardsAravind.SR

Hi,I tried to make an easy test of this board. when the button sw3 is pushed, LED 2 shall start blinking. Sadly it looks like my if statement equals always 0. Measuring the voltage on the testpin it looks like my MCU is sinking the complete voltage, no matter if the button is pressed or not. How do i configure the GPIO in a way that I could read from it without it to sink all the current? And where do I find this SIUL Documentation I should read before dealing with the advanced settings?  if(pal_lld_readpad(PORT_F, sw3) == 1){pal_lld_togglepad(PORT_F,led2);osalThreadDelayMilliseconds(50);};sw3 = PF13 = Pin84 

  Hi Team,  i have a query regarding the NAVIC module. Just like GPS module there is made in India navighation called as NAVIC. I wanted to know whether TI can provide me the module or EVT(EVALUATION KIT ) of NAVIC. Thnaks and regards, Aravind.S.R

Hi team ,     How to configer the firmware update for IRNSS and how to create a binary file.Firmware update which software is using?and any breakout board avaliable (Teseo-LIV4F) Thanks and regards Aravind

Could anyone share a project using LIN communication on an SPC570S50E microcontroller with me? Now the lin driver generated by SPC5Studio cannot send the message, and the simulation stops in the cycle of the sending function lin_master_transmit SPC5_LIN_WAIT_FOR_TX_COMPLETION.Register LINSR.LINS = Header Reception/Transmission.Use an oscilloscope to detect no waveform in the output.What am I not doing right Thank you in advance！ 

Dear ST community, I would like to have some information about the SPC574K72E7 microcontroller. I obtained from the website the datasheets and reference manuals for the microcontroller, I'm interest to know more details about the power supply for ADCs. There is a VDD_HV_ADV supply voltage and two voltage references for SD ADC and SAR ADC, from manuals it seems that is it possible to use the same supply for all of them, but I'm interested about the maximum current consumption of those pin in order to understand the correct manner to supply them. Is it also possible to use different power supply for the ADV pin and the reference voltages? Moreover, I would like to have some information about the possibility to integrate this microcontroller with a SBC or a PMIC with the aim to have several supplies and safety component in a single IC. Are there some SBCs specifically suggested for this microcontroller or some guidelines to create a correct design for the power supply, also taking into ac

Hi,I would like to know if the Stellar E1 series will be available through normal distribution channels and if it will be as easy to buy as an STM32? 

In the context of secure boot it is expected that HSW Firmware is authenticated before it is executed by HSM. How is HSM FW authentication triggered on every reset and who is responsible for initiating it when secure boot is enabled.Did not find this information in security manual of stellar. 

Hello I am interested at looking at the Teseoo-LIV3F for a application but I require a very fast TTFF. Having read up on the A-GNSS option will this be available any where or any location in the world as long as the server is accessible ?So no matter where you are as long as you can access the A-GNSS server the TTFF speed should improve considerably from up to 35s for COLD START to a few seconds after accessing and relaying the relevant data / information ?. The ephemeris data obtained from the server will be valid for your location and your sky ? thanks cab
