Okay, thanks! @György-Farkas
So when a GPIO is set to HIGH or LOW, is an internal pullup / down performed?
Greetings and thank you very much
I am doing a project to control the GPIOs with Omega2 + and Expansion Dock. However, I have a problem with GPIO18 and GPIO19. The ports are configured as GPIO.
When I configure the pins as input and read the GPIOs, the value alternates without exiting the pin. Why does the state change from high to low and vice versa without modifying the GPIO?
Thanks and regards!
Hi. I am trying to carry out a project with Omega2 + and I could use the schematics of the "adc-exp" board.
I would like to read 5V analog inputs, so I would have to power the ADS1115 at 5V. This will cause the ADC1115's high logic output level to be 5V, but the maximum for Omega2 + is 3.6V.
Also, the minimum VIH for ADS1115 is 0.7Vdd -> 0.7 * 5 = 3.5V, and omega has a maximum VOH of 3.3V.
How could I solve this? The schematics of the ADC-EXP board could come in handy.
Greetings and thank you very much.
