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...
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...
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...
Hello, I wanted to have SPI with DMA RX, below issues I face: 1. When SPI RX DMA function used with no TX DMA configured in MX (but blocking SPI TX used), It remains in RX busy state 2. When SPI RX DMA function used with blocking TX function, SPI wo...
Hi,I am having a hard time trying to configure the uC (STM32F446, but that is not important) to output a crafted signal via the Output Compare mode via DMA.What I want is to output a digital signal, that is created via Toggling the Channel Output Pin...
HelloI'm using the latest HAL library for STM32F030. I've set up a 512 byte transmit buffer for holding bytes that are to be transmitted out the UART using DMA in circular mode. The goal is to treat this 512 byte buffer as a circular transmit queue...
I have configured the ADC to use pins 1,2,3,4 for DMA transfer. I do get COM port output, however, I noticed that the outputted numbers aren't as they are supposed to be. The values for only 2 of the 4 pins change as they should. The other 2 do not.T...
