SI5351A and frequency counting with the STM32H743

Posted onMai 1, 2022Leave a comment

I wanted to play around with the SI5351A clock generator, but for verifying the output frequencies of the SI5351 I thought it would be great to have a frequency counter at hand. Unfortunately I do not own a frequency counter, so I looked for some Read More …

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

Summary: It is shown that the shape of the transfer function and of the SNR of the internal ADC of the STM32H7 vs. frequency of the applied signal can be explained with a very simple simulation model up to quite high signal frequencies. The PLL Read More …

Bandpass sampling and analog bandwidth of the 16-bit ADC peripheral of the STM32H7, Part II

Posted onJuni 4, 2021Juni 4, 20213 Comments

The STM32H7-application sends ADC data to the PC via USART3. Rx and Tx of USART3 are connected to the ST-Link debugger on board of the NUCLEO-STM32H743ZI. The ST-Link driver that gets installed when you install the STM32CubeIDE supplies also a virtual COM port that can Read More …
