Context: Using STM3Cube. STM2L431CC. (256KB flash, single bank)I have RAM code that successfully erase and program page 64 to 72. The same ram-code is then used to program page 0..8.The problem it fails to erase any page in range 0..63.No interrupts ...
Hi all,I am using SPI protocol on STM32H7 for interfacing with external ADC . STM32H7 is acting as master and ADC as slave . SPI clock i am using is at 40 Mhz. spi clock is getting disabled after 25-30 clock cycles. i want continuous clock for this ...
Hello, I'm using STM32F030R8 Nucleo board to read unitialized data from sram (for sram puf purpose). I'm using Standby mode to repeatedly reset the board. It is woken up by RTC alarm. The problem is that the data I receive after reset are always init...
Hello all, Please confirm fpscr is a special status register in STM32 L5 series controller?The IAR compiler is giving "Illegal register name" error, when I tried to execute the instuctions in c or cpp project using "asm volatile(mrs and msr instu...
I am trying to make a project to use spi with dma to transmit and receiveeverything seems fine in "HAL_SPI_TransmitReceive_DMA" and HAL_OK returns but the code in "HAL_SPI_TxRxCpltCallback" is not reached
Hello,I read the input data over SPI DMA, but when I added the AI part ICache and DCache are enabled.The problem is that when ICache and DCache are enabled, the SPI DMA is not working.How can I overcome this problem?
Hello I will use these crystals for STM32L4R9AII6HSE Crystal 16MHz ±10ppm 8pF 60 Ohms (with external capacitors of 6pf (assuming stray capacitance of 5pf) and ext resistor of 1.6KOhm)https://www.digikey.com/product-detail/en/jauch-quartz/Q-160-JXS22...
I'm using the FMC of the STM32H743 to drive a 16-bit 8080-bus LCD controller.I've tried using DMA, MDMA and a CPU-loop to transfer data to the 8080-bus, via the FMC.The transfer frequency does not depend on whether DMA, MDMA or CPU-loop is used. This...
hi,I'm new in ST. I'm trying to implement SPI communication between FPGA and STM32L051R8T6 (slave).I've initialized the spi bus in main (HAL_SPI_Init()), so that it is set to use (HAL_SPI_RxCpltCallback).and from main i called HAL_SPI_Receive_IT (to...
