SPI instead of SHIFTOUT - MAX7219

[Momboz]

What have you on hand to debug? Any PICKit 2, logic analyser, scope?

Any schematic?

I see HS OSC... it mean not much than >4MHz to me

More details, more help.

Hi Mister-e

Many thanks for the quick reaction.

As to the schematic nothing special but a PIC 16F876 with a 20 MHz crystal on a Mel PCB (PICPROTO-USB). I am checking with a scope (PCSU1000) the different signals on the PORTC C, i.e. the Serial Data Out (SDO) and the Serial Clock (SCK). Of course my PIC should be a master (or that's what I am trying to achieve).

Of course this works fine with other compilers like MikroC and CCS PICC on other hardware (EasyPIC5). And I want to have it running with PBP.

Please, let me know whether you need further detail on my system.
