H7 ADC revisited (Bandpass sampling and analog bandwidth of the 16-bit ADC peripheral of the STM32H7, Part IV)

Posted onApril 17, 2022April 17, 20222 Comments

The question that interested me was: How strongly does the SNR of the ADC-peripheral of the H7 depend on the chosen clock source? Unfortunately, neither the H7 datasheets nor application notes like AN5354 treat this topic. The FFT plot shown in figure 1 of AN5354 Read More …

NUCLEO-H743ZI vs. NUCLEO-H743ZI2 and STLINK V3 vs. STLINK V2

Posted onApril 6, 2022April 6, 20222 Comments

I wanted to try out one of the newer NUCLEO-H743ZI2 boards, because they are populated with MCUs with the newer mask revision V. In mask revision V, ST changed the clocking scheme of the ADC. This new clocking scheme is interesting and I wanted to Read More …
