Hello, I have never used STM before and I am trying to choose a product, but I cannot buy and try each of them due to their prices.I am doing high-frequency work and I need a screen. STM32H735G-DK is a suitable board for me. However, there is a quest...
Controller: STM32L011G4ULibraries: CMSISCompiler: arm-none-eabi-gcc version 13.2.1In order to change Capture Compare Register of TIM2 automatically every time when TIM2 updates, I want to use DMA to get the current CCR values from a const array. cons...
Hi guys,I want to do a dma with HAL library for a 1.3 inch st7798 driver display (uses stm32l476rg mcu)https://github.com/Floyd-Fish/ST7789-STM32I used the library in it works fine. but I want the screen to run faster (no scans should appear on the s...
Hi,I recently bought a Nucleo-H753ZI to test out some of my algorithms that will benefit from the extra compute power. However, I still need to interface with external sensors to read data from it at a very high rate (1kHz). The sensor in question is...
Heyho,I had probably some race condition, just want to make sure:the buffer switching in DMA's Double Buffer Mode (DBM) (both for DMA and BDMA) occurs immediately with the Transfer Complete (TC) interrupt?So when the DMA's TC ISR is entered (which ta...
Hello, With stm32G0, I can capture a pwm frequency and duty cycle using this configuration:DMA : Now, for pinout reasons, I want to do the same thing using channels 3 and 4 instead of channels 1 and 2 but I can't find a correct set of settings.On pa...
Processor: STM32H753I am attempting to continuously read an ADC, and transfer the data into a circular data buffer with the ADC. I configured everything in CubeMX. No matter what I try, I get a transfer error from the DMA the first time it reads. I t...
Complete noob in both uCs and C trying to understand how to actually read the documentation and where to look for the answers.I am using CubeMX to generate a majority of my code and using HAL.I have succesfully got DMA transfer to update different ti...
Hi,I understand this has been discussed before, but can we please get an official explanation of how the dma tail pointer works in the Stm32H7 eth mac ip block? It's extremely difficult to write software to support the eth mac when the docs and examp...
Hello, I have a SPI TX DMA, and I need to do the followingStep 1:start the TX DMA ,Step 2:stop the DMA,Step 3: store the NDTR register,Step 4: modify the size of the DMA SPIStep 5: restart the DMA with the new sizeStep 6: and restore the position of ...
