Got extio2 running on Core2?

fly4fun

Didn’t find examples for how to use extio2 on Core2? Anyone can help?

try to modify the M5Stack example like this:
replace:

#include <M5Stack.h>
M5.begin();
while (!extio.begin(&Wire, 21, 22, 0x45)) {

with:

#include <M5Core2.h>
M5.begin(true, false, true, true);
while (!extio.begin(&Wire, 32, 33, 0x45)) {

Thanks

Felix, you are a star! Now digital outputs and digital inputs are working. Only thing is, I always get returncode 1 back for all extio.x calls so not sure what this one left is?

Hello @fly4fun

thank you and thank you for reporting back. I am glad you got it working.

@m5stack: Please check out this pull-request. Thank you.

Most of those functions return true if successful (and false otherwise).

Thanks
Felix
