Hi,I am trying to send a CAN FD message with a STM32H743, using initialization code generated by CubeMX. Attached you can find a screenshot of the CubeMX settings. The clock to the FDCAN module is 100MHz. This is the code I use to send the message:HA...
I am using STM32F030R8T6, with 64kB flash size. Now I have <1k space left in the flash and whenever I load the ELF file with Atollic TrueSTUDIO the device doesn't work. The watchdog keeps resetting the device. However if I load the .HEX file, everyth...
Hello,My program uses two FSMC_Bank1 for the tft screen and memory (62WV51216ALL), NORSRAM3 is used for memory and NORSRAM4 for the screen, a problem has been identified that when accessing NORSRAM3 (memory), the CS signal (FSMC_NE3) goes low and rem...
Hi everyone!I'm using STM32L475 and I have a problem, the RTC Wake Up doesn't interrupt. I've set up the RTC in order to interrupt as follows (interrupt every 31.25 ms):static void MX_RTC_Init(void) { /* USER CODE BEGIN RTC_Init 0 */ /* USER ...
Like many I assume I'm having to code to cope with the differences between version V and version Y H7 parts. Things like having to change the call to set RTC drive current depending the version are irritating (errata on version Y).ASN5312 states that...
Hi,I tried to add a DMA for my ADC on STM32F767ZI with 216MHz. I just want to convert one Channel. In my Interface a select circular mode, enabled DMA continuous request, enabled Continuous conversation mode. When I start the DMA, my Buffer get fille...
I wonder when the STM32H7A/7B documentation will be available.The L5 documentation was released more than a year ago, and L5 is not yet available in stock at distributors. H7A / H7B are in stock and there is no sign of the documentation!
I am working on an automotive product that will interface with the vehicle's CAN bus network running at 500kbps. My question is, is the STM32F446 capable of reliable communication without a crystal? Or is it absolutely necessary? The last thing I wou...
Doing some electrical testing of a board I got back recently and It seems that the internal pullup of pin PA2 is applied at reset. Before flashing the device it seems that this pin is sitting high, and the voltage I see is consistent with the approx ...
