Hi,I've been trying to get the SDMM1 working on a custom board with an eMMC (ISSI 32GB).Are there any working examples from ST that verifies you have actually tested the MMC side of the HAL library to be working? @Imen DAHMEN I am able to get the CS...
Thank you for helping.How do I back up the registers when the power is turned off without the VBAT pin?Thank you.
Hi,I wonder if the STM32H743 can sample and convert 1 ADC sample in 10 nanoseconds?According to the specs the ADC speed (sample + convert) at 14bit resolution with 50MHz ADC clock , one sample will take 200 nanoseconds.I have no problem lowering the ...
