I've tried all ports now, all work as expected. Did you try other ports? Maybe your P6 is defective? Regards, Michael Am 10.07.19 um 12:21 schrieb Thomas Heuer:
here a picture with 3.3v to egpio5

I'll replicate your test with my module this evening. I did the test on EGPIO_8 routed to the DA26 connector, that worked correctly.

i use the internal Expansion. And there is 3.3v when powered over USB. pin 1 3.3v -> pin 18 EGPIO_5 pin 28 GND -> pin 18 EGPIO_5

* Where do you contact EGPIO5? * Where do you get 3.3V? External +3.3V is only present if you're powering from 12V

I have the egpio5 (port 6) pin on GND. then in the shell: egpio input 6.
then the gpio5 (port 6) pin to 3.3V. then in the shell: egpio input 6.
both return 0

Then you're now doing something wrong. Please describe your test setup.

Second, the reads were done on the output level registers, inputs are mapped to bit fields in 0x0e & 0x0f. Third, the max7317 needs a deselect between the tx and the rx. No, really, I've tried even half duplex mode, the deselect really is necessary. >> >> Fix is pushed.
