MPASM Assembly


MPASM

The backbone of PIC development, MPLAB IDE utilises the lowest form of the PIC micro controller language, assembly. While the command set may appear limited, all higher programming languages actually compile down to this level.

With this in mind, assembly is just as powerful as any other programming language, however the knowledge required to perform simple tasks may prove encumbering for some.


The software is completly free and can be downloaded from here

Not Quite Trivial - A Tip for using the Software UART with the PICKit 2 +

Not Quite Trivial - A Tip for using the Software UART with the PICKit 2
This tip is almost trivial, but it's a D'uh moment too.  Just in case anyone else has missed the obvious. here's a quick tip.   I usually use Swordfish's hardware UART routines and I don't recommend Swordfish's software UART for input, where there...

Simulating Analog Sensor Inputs +

Simulating Analog Sensor Inputs
When developing an embedded application using analog sensor inputs, testing at specific sensor levels can be difficult.  For example, in my icemaker controller project, actions need to occur at certain water levels.  Using the actual sensor...

Reliable Header Connectors +

Reliable Header Connectors
Header pins are ubiquitous on dev boards.  Jumpers can be used to make connections during tests and code development but real-world applications need reliable connections.  Connectors for single row headers have always been a problem for me,...

Swordfish Module - NMEA2
I had a couple of issues when using David Barkers module NMEA.bas on my Big GPS Clock project. In particular, variables were being corrupted making the program very unstable. I'm not familiar...

10 Keys on One Port Pin?
I'm working on a control system that will have several relays, a bunch of LEDs and a number of switches.  I was rapidly running out of port pins on a TAP-28 board to handle all the desired I/O.  Possible solutions included adding an I2C port...
