Hello,I'm using a Nucleo board (NUCLEO-G070RB) with STM32F103RB MCU and I try to use channel 11 of ADC1 mapped to PC1 to get values from a humidity sensor. I noticed that the values are invalid and it's not because of the sensor. I created a sample a...
Hello Everyone, I am trying to transmit data using DMA with SPI1 but each time I end up with a FIFO Error.. I 'm using Direct mode, MINC = 1, PINC = 0, DMA2, STREAM3, CHANNEL 3 For SPI_TX. I'm trying to send "Hello, World!!" But each time the FEIF3 i...
Hello. I have project from 2 years ago. During testing, a problem was discovered when sending commands from the master device to the slave device through the CAN. For some reason don't call callback - HAL_CAN_RxCpltCallback (there I analyze the incom...
Using COMP2 with internal voltage referenceWhen using COMP with interrupt as soon as I call HAL_COMP_START(&hcomp2); and interrupt is triggered even if COMP input GPIO is grounded.If i let the code run a trigger is never regenerated afterwards. I hav...
I use STM32F1 Value Line Discovery Kit.I would like to have a common interrupt handler and call the corresponding handler from that common handler.I am assuming the following.Specifically, I am trying to get the IPSR number from its common handler an...
Using STM32H743ZII am using SPI1 in 2 lines Rx only mode with DMA2 Stream 2 as in ST exampleI use Rx DMA with a buffer located in D2 RAM. Using debugger I found that the first reception works well, data gets written into my buffer. But my DMA doesn't...
Using an STM32F429 board, I am attempting to enable DMA transfers for the UART8 TX and RX. However, while reading the data sheet, I found the following DMA channel/stream mapping: You'll note that for the UART8 TX and RX DMA request, both requests li...
The project uses a Nucleo board with a STM32H723NG on it. I have adapted the NX_TCP_Server project and I am using Usart2 as a port to send and get data from a device that is then transferred over TCP. This all works fine when connected to the deskt...
I am working on a project that requires UART transmission using DMA. I am attempting to do this solely through register manipulation. Currently I am only able to transmit data using DMA transfer once, but when I try and send again, the UART sends not...
