Hello,perhaps someone here has an idea what's going wrong:I wrote a small program with cube ide to calculate a crc32 (standard polynom 0x4c11db7). It took me some time, but now I get the same result when using HAL_CRC_generate and 'manually' feeding ...
Hi， I'm using STM32G431 to drive my SPI screen. Due to the high cpu load, i decided to change the IT sending mode to DMA. After putting a little changes on code, it doesn't work any more, and i have confirmed it will work again once get it back to IT...
Hello,I'm commucating two STM32 F4 boards using SPIThe first board is configured as a Master and used to only transmit data #define message_tx_size 4 uint8_t message_tx[message_tx_size] = "ABCD"; .... int main(void){ while (1){ HAL_SPI_Transmit...
I would like to sample the entire GPIOA Port using the DMA and TIM16. TIM16 triggers the DMA which in turn is supposed to copy the content of the IDR register of GPIO onto an array. This works fine if I use the CNT register of TIM16 as CPAR. When I s...
Hello!I have not been able to figure out how to get PSSI DMA working for the H5. For other peripherals, there is a DMA-tab in the configuration, but not for PSSI. Similarly, I have not been able to find any way of using interrupts for transmitting or...
Hello,I'm working on a led display solution and I'm using a STM32U5 with GPDMA to pilot daisy-chained shift-registers through GPIOs. I could have used the SPI interface but I'm driving several differents chains of shift registers and I prefer to make...
Dear Community,I am currently facing this issue where my STM32 Black Pill F411CE suddenly went into hard fault during runtime. The MCU was permanently gone and was not able to be re-programmed, and four others that I connected to the same hardware we...
Hello,I have been utilizing the OTG_HS peripheral on an STM32U5A5 to act as a USB host. I am using the USBx stack in a non-secure application and initializing the peripheral as follows: VOID USBX_APP_Host_Init(VOID) { MX_USB_HCD_Init(); ux_host...
Hello,I am trying to implement the following: a timer (tim3) is set to PWM generation, outputting a pulse periodically. Its TRGO triggers the DMA channel to request I2C to initiate a read transaction, read 8 bytes and generate an event interrupt (TC ...
Hello.I have problems to get DMA with ADC working.I'd like to collect 2 values from PA3 and PA4 and store them in an array (convertedData_u16). I configured ADC1 with Channels 8 and 9, and GPDMA1 with Channel1.I can see that data is being collected i...
