First attempt at printing to an LCD display from a dsPIC30F4011
The following example is my first attempt at printing to an LCD display using the dsPIC30F4011 microcontroller. The display I’m using is a 16×1 character screen with what I think is a standard Hitachi...

PWM servo control example for the PIC18F14K50
This is my first program for the PIC18F14K50 20-pin microcontroller. I haven’t used this chip before, but it seems to have some useful features including USB connectivity, so I intend to investigate it...

Simple PI control using the dsPIC30F4011
This is an initial sketch of a simple PI controller using the dsPIC30F4011. I hope to add in quite a bit more detail and explanation to accompany this in the coming days, but I thought I’d post the...

Relatively simple DFT example for dsPIC
I’ve been trying to create a simple DFT example for the dsPIC. I found it more difficult than I expected to come up with something which is both useful and readable. I’m intentionally not doing either...
