AIN/LCD?? problem

Testing/Troubleshooting

Hi List

Today is the day when I moved from PIC16F877 to the new one - 18F452 with MIOS.  Loading the firmware was no problem. It works fine, but:

when I turn a pot (doesn’t matter which) to a value <15 the LCD turns off. When I move it backto the value above 15 the LCD turns on. When it is turned off and i touch other pots (to send value above 15) LCD turns on again.

Last, when LCD doesn’t display anything, midi-ox recives some values so the box is working.

A didn’t have such an issue with 16f - everything workeg fine, so hardware is i suppose ok.

Any solutions?

I’ve measured voltage on power lines with all leds on: 5,05V (and the LCD down).

I checked the old PIC16F and old osc. - it works!

I’ve also uploaded the application midibox64v2.4 once again, still no success :frowning:

Did you do all hardware mods? Means: new quartz (10 Mhz) and here: http://www.ucapps.de/mios_v1_7_hardware_mods.html

When I upgraded my MB64 to the new MIOS, it worked out well. So… should work out somewhow.  :slight_smile:
