Hi I m using SPI DMA on H7 series, and notice under SPIx_TX and SPIx_RX there are at least 14 DMA channels to choose from, i.e DMA1 Stream 0-7 and DMA2 0-7. Can i select these "channel" randomly or is there a reference manual that state otherwise? L...
I want to know the reliability data for M41T0M6F.so please provide to me soon. thank you
Is STM32F446MEY6MTR of MIL grade microcontroller? Is any variant of STM32F446xx have MIL 464/461 or MIL810G standard?
Hey everyone, I'm learning about USB CDC and soon USB HID. I think I successfully program the stm32 as a cdc device because I can connect to it, and I can read and write serial commands through a terminal. I can even catch the serial buffer through t...
I used STM32H563 transmit a message through I3C CCC direct.I create a new CCC command "0xA0".Control send the command to target.But target will enter HAL_I3C_ER_IRQHandlerUesd the general command "0x89".The target can receive this command. The Buffer...
Does anybody have an example code how to use SAI in STM32U5A5 as PDM interface?I use STM32U5A5, with LQFP64 package. So, I understand from datasheet: the SAI (I have just SAI1 available om pins), supports PDM interface (for MEMS MICs). My package has...
Hi,everyone! I want to know if FDCAN ( I'm using STM32H7) has lost the automatic Bus-off Recovery mechanism. Looking Forward to get your reply.Thanks!
I have an STM32WB55CGU6 on a custom board with a 32MHz HSE. I'm using low power uart1 with PA2 & PA3 pins. My settings for it are: - baud rate 9600- word length 8 bits- 1 stop bit- parity noneIt won't transmit. Cube doesn't receive it, any terminal ...
I tried to set up a UART connection from my custom board to my PC but encountered some problems and after a bit of probing, it seems that UART TX and UART RX are connected to GND. Do I need to enable UART somewhere for the ST-LINK ? Also why do some ...
I'm trying to send a fixed length packet in SPI slave mode from the STM32 via DMA. The SPI master may send/recv longer than that fixed length packet. It would be nice if the STM32 just sends 0 one the transactions is complete, but it seems to want to...
