Using:STM32L4SVITDBANK=1The reference manual seems to state that a Mass Erase must be performed before every FSTPG. However the requirement is not clear. Assuming it is correct that a Mass Erase is required to use FSTPG: 1.Is there a time window ...
Hi,I'm trying to use the SDRAM from my STM32F429-Disco Board. I have created a function to initialize the SDRAM which is executed in the main-function. The SDRAM implementation was done with the following instruction: http://en.radzio.dxp.pl/stm32f42...
Hi,I would like to detect last used address in flash to be able to backup the firmware from internal flash memory to external from my bootloader. I know the start address where from start copying data, but don't know the end. I was unable to found a ...
Hello, ST expertsSTM32F415RGT6 is used on custom board. Everything looks fine except that SDIO opertions. f_write function is called at an interval about 500ms to write 512Bytes to SD card. SDIO_CLK is 24MHz, 4bit bus wide. I really don't know why t...
Hello, I am new to the embedded community and was facing a problem figuring out the pwm resolution of the STM32F030F4P6TR microcontroller. I went throught the datasheet and the user manual but did not find any solution to my problem.Thanks,Apurv.
I'm using a STM32F072 Discovery Board. I'm trying to use Channel 1 (PA_1) and Vref being supplied externally at VDDA(Pin number 13) . I have disabled internal Vref using the function call ADC_VrefintCmd(DISABLE);Even in register window Vrefint is n...
Recently, I began to deal with the STM32F7 stone, as the STM32F4 lacked speed. By the result, I realized that if you simply run the same program (calculating digital filters) on F4 and F7 at the maximum core frequency, then the performance does not i...
