Finally I have build de extra print to test the GPIO option and I'm happy to report that the GPIO and I2C are both working.

Sorry for the delay but I had to visit the dentists . Ran a partial test with the 65536 test program which is in my opinion OK. To test the GPIO I must build an extra print...

Hi Bill,

It is very interesting to see that it works with two languages : Assembly and BASIC. I hope you also het the GPIO working just in case.

Today ran some further tests: - Power on Pi , start memu run loop 0-255 loop program . Result : OK - Close memu, start memu run loop 0-255 loop program. Result : OK - Reboot Pi, start memu run loop 0-255 loop program . Result : OK - Close memu, Start Memu run 255 x 0-255 loop program : Result OK. If...

I have compiled the source and it seems to be working. Running a longer test now with as base my loop test program. Now out and input is tested 65536 times . I will run further tests tomorrow. Particular exit and reentering the MEMU simulator and switching on and off the Pi-Zero.

Can I propose I get the code and test it ?.

Another update : when the unit starts up completely fresh the lines in hardware.c :
gio_input (8, pinPIN, 0xFF);
gio_output (8, pinPOT, 0xFF);
Do work so I have put them back. It is really a bit looking

Your efforts are highly appreciated I hope to place schematics also today.

Hello I have made a page with software I have written to test the emulator and some photos of the print

I have tested the code and no joy ;-( OK. I will have to get some hardware set up and test properly. Have you tried the alternate method using the kernel driver?
