I can want to change NDTR after enabling DMA stream. but I can't. This is the part of code... LL_DMA_EnableStream(DMA1, LL_DMA_STREAM_5); // works fine now // but I want to change the data length only LL_DMA_SetDataLength(DMA1, LL_D...
We have a product with a STM32F373CC where we calibrate the RTC in Production and store the calibration factor in Data0 and Data1 of the Option Bytes (OBR).Tracing through the (legacy) code via my debugger, I can see the OBR values being written corr...
I am using the CORDIC on an STM32G4 for a project and was curious about the difference in performance based on the compiler optimization level. With no optimizations, LL_CORDIC_FUNCTION_PHASE completed in 113 cycles. With O1 optimizations, LL_CORDIC_...
Hello, fellow forum members,I'm acquiring data from an ADC using DMA, and writing the filled buffer in SDCard, using SDMMC, also with DMA, on an STM32L452RC.I recently came across an interesting challenge involving power optimization while waiting fo...
Hi guys,i would like to ask you about accessing FMC bank2. Currently i have connected SRAM to bank1 and LCD to bank2 but i cannot access bank2. Also i cannot find location of bank2 in memory map in reference manual. Currently it looks like bank2 is n...
Hi coomunity.. Very easy question this time.. Is this development board ok for testing a custom bootloader from usb for updating fw from a text file inside the usb ? https://www.st.com/en/evaluation-tools/32f429idiscovery.html
Hi,Could someone plz point me example code on how to use Brown Out Reset or Voltage supervisor to monitor Vdd voltage, if it's less than some value, I can reset mcu.
Using SMTF32F1x or SMTF32F4x or another, is it possible to receive/identify a generic error-frame on CAN-bus?I'm using call back receiving and if I transmit an error-frame (I'm using Vector Canalyzer as tool), my call back is not running.I also tried...
