Mango Pi

Continuing my saga with electronics – went for an electronics workshop by Kits’n’Spares – the workshop was nothing to talk about – however did get me a Mango Pi – a development board for the PIC processors.

Well surprise – surprise – doesn’t support Mac OS, at least I couldn’t get it to work. Finally gave up, started Windows XP in parallels, downloaded the software and started programming. Its not as easy as the arduino, but fun nevertheless. Took me a whole day to program the LCD. The code samples provided with the kit didn’t work and had to troll through the net to understand how to make it work. Finally got it working, here’s the code:

#pragma config LVP = ON         // Low-Voltage (Single-Supply) In-Circuit Serial Programming Enable bit (RB3/PGM pin has PGM function; low-voltage programming enabled)
#pragma config CPD = OFF        // Data EEPROM Memory Code Protection bit (Data EEPROM code protection off)
#pragma config WRT = OFF        // Flash Program Memory Write Enable bits (Write protection off; all program memory may be written to by EECON control)
#pragma config CP = OFF         // Flash Program Memory Code Protection bit (Code protection off)
