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 ...
I use STM32F407 and external NAND Flash.I modify void SysTick_Handler(void) -> add GPIO Toggle.So Normal Condition, GPIO pin is toggled regularly.When HAL_NAND_Erase_Block() excute, GPIO pin is toggle irregularly.After HAL_NAND_Erase_Block() finish...
Sup! I've tried to revive my old HAL-based project written a while ago for FW 1.6.1, fixing some minor bugs. Unfortunately, i removed old package long time ago, so i installed latest version 1.8.0. And my code isn't working anymore. After calling to ...
