hi everyone want to use interrupt in main.c i am using extern "C" for this purpose but its couldn't compile/* USER CODE BEGIN 4 */ extern "C" void TIM2_IRQHandler(void) { // Handle update interrupts (update interrupt flag is set) if (TIM2->SR & TIM_S...
Hi everyone,I'm trying to perform some ADC conversions triggered on a timer rising edge, this timer can be up to 1MHz.I set up everything in cubeMX and can perform those conversions, but the delay is too high for my application.My current problem is ...
battery backup ram works after power on. stops working ( get hard fault ) upon access to variable in battery backup ram. battery backup ram works when developement system dissconnected. sporadicaly stops working when ijet or segger connected to nu...
Hello everyone,I am developing a project with STM32F750N8 using Keil IDE, JLink Edu debugger.Also using W25Q128 QSPI Flash. I want to load my hex to the qspi flash and run the software from there (with memory mapped mode).I build a BSP Library that c...
Hi everyone.I have edited my original question, it seems I haven't the permissions to delete. I found the original issue to de data alignment.Thanks
here's my initialization code for spi and rc522:/* USER CODE BEGIN SPI1_Init 1 */ LL_SPI_SetRxFIFOThreshold(SPI1,LL_SPI_RX_FIFO_TH_QUARTER); /* USER CODE END SPI1_Init 1 */ /* SPI1 parameter configuration*/ SPI_InitStruct.TransferDirection = LL_SPI_F...
Hi,I need to periodically count the number of pulses of signal A between two rising edges of signal B. For that I use a timer (TIM2) in ETR mode (signal A is the ETR input), input capture on signal B and slave trigger+reset on signal B rising edge.No...
Hello everyone,Where can i get the ADC acquisition time for stm32h753_tfbga100 IC??
I have a problem accessing a SRAM connected via a 16bit databus to the FMC on an STM32F469. The processor is running 168MHz, and the FMC configuration is this: hsram1.Instance = FMC_NORSRAM_DEVICE; hsram1.Extended = FMC_NORSRAM_EXTENDED_DEVICE...
I've read AN5306 and it has many helpful explanations, but it does a poor job of actually listing which selector values are used to configure each of the multiplexers - especially the mysterious undocumented one that seems to bridge around the VMSEL ...
