Reading input from the board for temperature sensor

Jada246 — Mon, 11 Jan 2021 18:44:01 GMT

Firstly I set the GPIO to input using GPIO -> DIRCLR[0] =(1UL << sensor1)

//sensor 1 is gpio 19 which is the output voltage from temperature sensor

im trying to read it and print it to the console using

GPIO -> B[0][sensor1]

the problem is I’m constantly getting 0 as the voltage.

Please first use logic to confirm there is signal in gpio pin.

Then check your code, you'd better refer to to gpio demo, which chip do you used,

I can help to provide demo.

Also check whether enable GPIO clock.
