hi;

I'm trying to run an LCD on kit059.

but when selecting pins p12 [6: 0] and p12 [7: 1] blue others white.

for example, if I select p0 [6: 0], the lcd does not work. nothing on the screen.

but if I select p12 [6: 0] or p12 [7: 1], the lcd works.it works when you assign another task to the other pins. but I don't understand what the problem is.

Do we have to choose p12 [6: 0] or p12 [7: 1]?

Best Regards.

Hello.

On KIT059, P0_2, P0_3, P0_4, are each connected to 1uF capacitor for reference voltages.

You'll need to de-solder these capacitors if you want to use Port 0 for LCD.

Also, be aware of the other connections for Port 12 on KIT059:

P12_6, P12_7, UART connections to Kitprog.

P12_0, P12_1, I2C connections to Kitprog.

These connections do not appear to be affecting your  LCD interface.  But in the future, you may wish to use USB-UART bridge that Kitprog offers and this would interfere with LCD interface.

Good luck with your project.
