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...

Hi,Having our board in which we have interfaced STM32F429 to SRAM (IS61WV204816BLL) .Facing issue while reading back the data after writing.Actual scenario: Have written a SRAM test code in which am writing 10 bytes starting from SRAM location 0x640...
I use the RTC of STM32F407 with LSE (32.768 kHz).A battery is connected to VBAT for backup.In the reference manual, the Backup operating voltage is at least 1.65V, but the RTC is actually backed up to about 0.3V.I do not know the reason. Could you te...
