Free video wall test software.
Added 2019-01-24 03:29:14 +0000 UTCIt turns out that the video wall panel supplied in the Project MC2 "handbag" is a standard module.

I amused myself by reverse engineering it and then writing a piece of software to do a full panel test with nothing more than a PIC16F627A microcontroller driving the RGB, clock, latch and output enable pins.
I've included a link to the software in the video description in case you want to download and try it yourselves. The .asm file is the full code that I've documented well to make it easier to read. The .hex file is precompiled and ready to load straight onto a chip with any programmer that can accommodate a PIC16F627A.
I also added a bit of software that continually scrolls random colour data across the screen.

It's very efficient, but it can't beat the speed and versatility of development of something like an Arduino.

2019-01-27 07:17:33 +0000 UTCBack in the early days of computers the magazines routinely referred to assembly style programming as machine code for some reason. It seemed cool that people could program in machine code. My first base level program was entered as hex.

2019-01-27 07:16:41 +0000 UTCProjects that had worked on another processor in the family didn't work on the new processor until you had tracked down and disabled all the new pin functions they enabled by default. Like a comparator input in this case.

2019-01-24 20:19:00 +0000 UTCIt would be fun to try injecting an audio signal into the raw data pins, such as the headphone left+right channels from an MP3 player.

2019-01-24 17:57:00 +0000 UTCMachine code is the actual binary data (represented in binary, octal, hex, or BCD. Assembly code is a source code where each instruction is 1 for 1 with the processor's instruction set.
