I'm working with STM32h745 SPI to interface adc ADS7046. I trying to achieve sampling rate at least 2msps. Below I attach some snap for SCLK and CS signal. i trying to minimize time between sclk regenerate pulses. it is taking long time so I can't be able to reach sampling rate. I trying with different methods like Interrupt, DMA but same got. so can...

Can I find only pbkdf2 implementation in C without SHA256? I want to use clear pbkdf2 algorithm with SHA256 from library used for STM32 microprocessors. I checked fastpbkdf2 repository, but there is only called pbkdf2 from openssl library which I don't want. I have optimized SHA256 in my library for STM32
