Digital inputs in STM32 boards ?

[AElta.1]

I am working on reading an External 3 bit parallel CMOS ADC (4-8 MSPS)(from MAX2771 board or Eva KIT) GNSS digital output. I want to read this digital output pins using the NUCLEO-H723ZG, I do not know if there is digital inputs pin in the board ?

if so what is speed of the GPIO pins ?

thanks in advanced

All the pins in the GPIO bank (16 pins) can be read via GPIOx->IDR. Could perhaps use a TIM input pin to trigger DMA.

F​or a clocked parallel input, perhaps look at DCMI

The User Manual has details of all available pins - inputs, outputs, etc.

Also look at the schematics.
