SWV working on Nucleo-F446ZE but not on Nucleo-F767ZI or STM32F769-Disco
I've created three (nearly) identical test projects, one for a Nucleo-446Ze, one for Nucleo-767Ze and one for a STM32F769-Disco. They are all nearly identical: 1) Trace Asynchronous SW 2) FreeRTOS 3) A single task created for each user LED to blink t...
Resolved! DMA transfer is completed before transmitting all the data to SRAM (or data is corrupted)
I am currently working on a touch screen for one of our products. I built an LCD intel 8080 driver with the FMC and it's not working with DMA.The image is only partially flushed to the screen. It seems that there is some kind of limits to the transfe...
Proper way to send 16 bit SPI data
I need to send 8 bit and 16 bit data with my 32f769. I found a register modification routine to change the bits from 8 to 16 and back. I checked the SFRs and it works (changing the bits that is),When I transmit 8 bit data, all is fine. I can send ...
Resolved! CAN BUS INTERRUPTS - HAL_CAN_RxFifo0MsgPendingCallback never triggers / I never get the Rx Interrupt.
Hello,My setup is as follows: I have an STM32F469I MCU connected (via SN65HVD230 CAN Board) to the CAN bus of an STM32MP157c-EV1 MPU board which is running Debian.My goal is to make the MCU send CAN frames periodically to the MPU, and with the CAN Ut...
Resolved! Is there a better way to generate a variable frequency using DMA and TIM2 than what is described in AN2820 Paragraph 2.2.1 Page 13/14?
It is doing exactly what I want, It is ramping up the frequency at the start, staying steady for some period of time, and then ramping down. In my case, I need up to 38400 steps. And I want to count steps, not time. My first thought was to have a big...
STM32F769 SPDIFRX Interupt
Hello there, I am developing an application that takes data out of SPDIFRX port and I am trying to do this with interupts instead of pollingI am basing my code on polling example that you can find here: https://www.st.com/en/embedded-software/stm32cu...
How do I clear my output buffer?
I'm using an STM32F103C8T6 "Blue Pill" connected to Ublox module using UART. It just a simple operation of receiving data and then print them to serial monitor using CDC_Transmit()HAL_UART_Receive(&huart1, receivedData, sizeof receivedData, HAL_MAX_D...
