Hii... I'm using TL1431AIYDT to get 5V reference supply ( (+/-)20mV tolerance). My input voltage is 6V. We need to protect the IC from Short To Battery (7V to 18V) (at the output). We are planning to use a schottky to protect from STB. During STB (18V), the VREF pin rises to 9V (50% due to voltage divider). What's the maximum voltage that can be given to VREF pin of TL1431AIYDT ??? Attaching the simulation pic for your reference.

The FlexRay cluster I have here consist of 2 FlexRay cold-start nodes and the third node, spc58ec mcu non-cold start node. Can anybody suggest what can go wrong ?

I tried to use another driver, but could only erase and program bank0, not bank1.

I use spc58nh-disp board.​Import board is SPC58xHxx_cut2. ​how to use eeprom or flash memory....where is example?

I want to trace ContextSwitchIn and ContextSwitchOut events. I defined two functions for this. #define traceTASK_SWITCHED_OUT() getTASK_SWITCHED_OUT_EVENT(pxCurrentTCB) #define traceTASK_SWITCHED_IN() getTASK_SWITCHED_IN_EVENT(pxCurrentTCB)I put the two functions at the end of the FreeRTOSConfig.h file. But, It is returning to the original file after clean-generate the code again.It says in the help that patching mode only works on lib/src, lib/include and lib/rsc folders.FreeRTOSConfig.h is located in the cfg folder. How can I solve this problem? 

After IIC module is initialized, when I prepared the data and to write the IBCR register to send it, after the register is written with the value 0x70(master mode, tx mode, interrupt enable and generate START condition), the value read from the IBCR is 0x50. Who can tell me what's wrong?Thanks!

Hello.​i use SPC5Studio tooli started import samples from application library / Bootloader ...the project complie is ok.i modified Makefile. i know this file automatically generatedbut i must modify the compile option"HEX = $(U_GHS_PATH)gsrec -hex386" to "HEX = $(U_GHS_PATH)gsrec -hex386 -crc32"​and then, this compile is ok.​but. If i generate it again, the additional option disappears (-crc32).prevent the makefile from being regenerated,I want to put an option in the place that creates the makefile.​thanks

Hi ST team,I'm working with spc570s MCU.I want to write some data to the on chip EEPROM and read back.I have tested it by the code provided in the examples of SPC5Studio.It's working.problem :-I want to write and read data by the bootloader example code provided in the SPC5Studio. I need to write and read data before getting the new application code by the host.Could you please provide me the necessary details immediately?Thanks,Kasun

SPC58EC80E1 is used and only lin slave mode is used.So, in the example code (SPC58ECxx_RLA LIN Test Application for Discovery), delete the lin_lld_start (&LIN_MASTER....) corresponding to the master and activate only lin_lld_start (&LIN_SLAVE...).and then,​If i send data (id+8bytes: 0x3c, 0x11,0x12,0x13,0x14,0x15,0x16,0x17,0x18) from the external device (PEAK-LIN) to the board, slave_rx_callback is called, but idMessage (0x3C) is received, but buffer is received only 1byte (0x11) and after 2bytes is received 0x00, 0x00 .....)​I wonder if spc5xx_lin_rxi_interrupt should be modified or what settings should be set when initializing.​LIN Configuration Setting of SPC58ECxx Low Level Drivers Component RLA is set to Synchronous and LIN_SLAVE set LD1And.Slave_tx_callback seems to be operated by the master function of the sample code.I want to send the data to the master of the external device after slave_rx_callback. I want to know how to call save_tx_callback. thanks

Hello,i use spc58ec80e1 in our project. (spc5studio)the bootloader code is flashed in address 0x00fc0000 (Boot Mode : copy in flash),and application code is flashed in address 0x01000000.(Boot Mode : Excute from flash)After the bootloader starts to operate after power, it wants to jump to the application code using timeout using PIT.but it does not work.Looking at the community and so on,void application(){ void (*user_application)(void); uint32_t jump_address_pointer; vuint32_t jump_address; jump_address_pointer = (0x01000000 + 0x4); jump_address = *((vuint32_t*)(jump_address_pointer)); SPC5_PIT0_DISABLE_CLOCK(); /* * disable interrupt */ irqIsrDisable(); /* * Disable XOSC and set DRUN mode */ MC_ME.DRUN_MC.R = SPC5_ME_MC_SYSCLK_IRC | SPC5_ME_MC_IRCON | SPC5_ME_MC_XOSCON | SPC5_ME_MC_FLAON_NORMAL | SPC5_ME_MC_MVRON; if (SPCSetRunMode(SPC5_RUNMODE_DRUN) == CLOCK_FAILED) { SPC5_CLOCK_FAILURE_HOOK(); } user_application = (void(*)(void))jump_address; user_application();}I've tried it, but

Hi,I always take an error "EEPROM_ERROR_FLASH_PROGRAM" while I was trying to write some data on EEPROM.So, I debugged and realized It returned an error in verify stage.I give uint32 WriteBuffer[100] and It makes 400 bytes.In verify stage EEPROM driver is using a counter that the data type is uint8. So, It means just 256 bytes can be verified.But there is no limit control on the eeprom_write function and no warning for about this. uint32_t actualsize; uint16_t idsize; uint64_t buffer; uint32_t buffaddress; uint8_t counter; uint8_t i; uint32_t returnvalue; uint32_t address; uint32_t idaddress; uint32_t alignedbytes; uint32_t notalignedbytes; uint32_t nuomofcycles; uint32_t tempsource; uint8_t invalidateid;   . . .   /* Verify written data */ address = eepromp->config->blockConfig[eepromp->currentBlock].startAddr + eepromp->config->blockConfig[eepromp->currentBlock].size - eepromp->freespace; address += 16U; /*point to data */ for (counter

Hello. I am trying to integrate ISO 26262 functional safety ASIL B requirements into our project which uses STM8AF52xxFor this purpose I need STM8A-SafeASIL - Automotive functional safety package for STM8AF and STM8AL Series MCUs in systems implementing safety functions up to ISO 26262 ASIL B - STMicroelectronics. However there is no link to download the same. Can anyone help me on the same?

hello. alli use SPC58EC80E1this MCU has 4M flash so. I want to divide this flash into two parts.(ex : 2M+2M)and. I want to have two builded images and execute one of the two images by a certain value.Should I modify the application.ld file? Or should I just go to the designated address?plz. give me idea.thanks.best regards.​

Hello allI would like to do SPI through DMA.Before transmitting data, we want to send the command of the PUSHR register together, so one channel wants to combine the data and transmit it through the minor loop link.However, there is a problem that it is not transmitted correctly. (data_array2 has been confirmed to be changed correctly.)Below is my code.​vuint32_t data_array2[32] = {0x80010000, 0x80010000, 0x80010000, 0x80010000, 0x80010000, 0x80010000, 0x80010000, 0x80010000, 0x80010000, 0x80010000, 0x80010000, 0x80010000, 0x80010000, 0x80010000, 0x80010000, 0x80010000, 0x80010000, 0x80010000, 0x80010000, 0x80010000, 0x80010000, 0x80010000, 0x80010000, 0x80010000, 0x80010000, 0x80010000, 0x80010000, 0x80010000, 0x80010000, 0x80010000, 0x80010000, 0x08010000};uint16_t data_array3[32] =  {0xFFA1, 0xFFA2, 0xFFA3, 0xFFA4, 0xFFA5, 0xFFA6, 0xFFA7, 0xFFA8, 0xFFB1, 0xFFB2, 0xFFB3, 0xFFB4, 0xFFB5, 0xFFB6, 0xFFB7, 0xFFB8, 0xFFC1, 0xFFC2, 0xFFC3, 0xFFC4, 0xFFC5, 0xFFC6, 0xFFC7, 0xFFC8, 0xFFD

Hello I have SPC582B54 and I want to use an UART interface. The problem is that it can't enter the initialization mode. The INIT bit in CR1 is set but the registers (f.e. baud rate registers) could not be written. It does not matter if this bit bit is set or not, the registers behave the same way - as the init mode is not entered. LIN_CLK is 42M (PLL0/1) Core clk 48M, PBRIDGE 24MHz. Is something more I have to do to enter the initialization mode?

hello,where can i download Windriver for SPC5Studio?

I am using Wind River Diab Compiler and Wind River Workbench IDE for developmment of our project. We are using ST BOLERO SPC560B60L3 microcontroller for our project. For this project, low level driver code we are planning to generate via SPC5 Studio.  This generated driver code via SPC5 Studio, we want to compile via Wind River Workbench. How i can do this ??Any documentation regarding the same then please share....
