ADC analog bandwidth tests:--board nucleo-G474re, on-board voltage reference.--sampling rate 2.8 msps, free-run mode, 12-bits, --156 kHz & 19.47 MHz.  Approximately at 19 MHz ADC has ENOB < 6 bits, limiting factor seems to be aperture jitter about 12...
CubeMx version 5.4.0., STM32Cube_FW_H7_V1.5.0ADC Oversampling Ratio EditBox doesn't allow to enter 1024, max value 1023. But it should, HAL_ driver makes subtraction -1, so 1024 is correct value.
I discovered that Ethernet module on the nucleo-H743zi generates a lot of interference for analog domain. I thought, that if peripheral devise was not configured in the software and was not given explicit permition to run, it should stay in power do...
Seems there is an error in the STLink firmware (upgraded to the latest version just now), clock is off about 1%.
I have two nucleo-144 boards, stm32F767zi and stm32H743zi. Both cortex-M7, pin compatible, and pretty close in AHBx (GPIO) clock, 216 vs 200 MHz.Testing TFT LCD display library, that required fast 8-bits access to the LCD data bus, I discovered that ...
