Project Update: Spunk The Annoying Robot

The last robot I built was a Roomba Sumo Robot (Talos) for a small competition with co-workers. While collecting parts for this little eBay robot platform I got for somewhere in the neighborhood of 15$USD, I grabbed my Pololu motor controller and remember that I wrote that whole Sumo robot in ASM; that was a…

Checkout: @tymkrs MIDI In Me + PIC18F14K22

I don’t want anyone thinking they’re going to see a bunch of music related items on the blog because I’m really no good at such things. My brother on the other hand is very talented and we recently decided he needed some more MIDI toys. A lot of his music is already created with the…

Project: Si4707 Weather Radio

I purchased a Silicon Labs Si4707 weather band radio break out board (BOB) from Sparkfun a couple of months ago and finally did something with it. The Si4707 has a SAME ( Specific Area Message Encoding ) processor that allows alerting for only for a certain kinds of warnings. The weather band radio board receives…

I2C with the 16F1509 and TCN75A

What are you looking at? More code. Joy! I know I’ve been doing a lot of these code tidbits lately but it’s what has been driving me to sit at the bench. This is my first I2C project.. I pulled heavily from many sources of snippets, documentation and projects; microchip forums (*some of it wrong*),…

Code and Documents

All related files I’ve uploaded (as of 2014) and code: I have found I never update this…. you’ll have to look inline with the articles. I tag fairly well anyhow. CODE: Right click and Save As… Files with potential updates can be found at github:¬†https://github.com/chasxmd and NOT here. My other github is https://github.com/chasihler/ All files…

PIC 16F1509 NCO code sample

I didn’t read a forum post all the way through (or maybe I was just tired) and I accidentally responded to question about PWM; however the question was specifically about using the numerically controlled oscillator (NCO). I decided to take a look at this module and wrote some quick code. I also have been testing…

Testing an LCD with the PIC 16F1509 and the XC8 compiler

Nuts and Volts, January 2014 had an article named “The (Nearly) Universal Process Monitor”. The whole magazine had a number of Microchip PIC based articles which is rare these days, as the articles win out to other platforms such as MSP430, Propeller, and Arduino. The article is a pretty nice project but I went to…

WWVB Time Signal Generator Test w/ HEX

[Edit: I’ve added the .asm code in the “Code” page in the menu above. Below you can find the .HEX file for easy programming] A successful test on my WWVB signal generator. I’m going to shy away from calling it a transmitter because I don’t think there is any allowances for any broadcasting on 60KHz,…

PWM on the PIC16F1509 in ASM

[Edit: If you’re looking for NCO (numerically controlled oscillator) usage instead of the PWM module take a look here instead. However note the code is in C (for XC8) not ASM] Another lazy Sunday… A lot of OT the last few weeks at work and Sunday about the only day I have for relaxation so…

TAUTIC’s 20 Pin Development Kit

I am a sucker for development kits/boards; they are cheap and if you have the room in your project they shave tons of room off your development time. Semi-recently, I was looking for a 18 or 20 PIC development board to plug into a main board. There are tons of boards that have various relays…
