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 ...
So does anyone know if this kind of examples for this MPU family are on the way? Or have someone done this porting and have tips for helping out with the job?
Hello,I have a project in which I use an external timer module. I want to measure the time that a function takes. I have a function say _time returnTime() which is configured in such a way that it returns a time with 10 microsecond resolution. In the...
We have a custom board with an STM32F469 and a SanDisk iNAND 7250-I 8GB eMMC. We have our HCLK set to 168MHz and SDIO clock at 48MHz, 8-bit data width. Using CubeMX (v4.26.1), the user is responsible for supplying the necessary code in the user_diski...
