I've been over playing with the Propeller chip the last couple months, with the addition of i2c routines, perhaps it would be possible to use the SD card on the PICAXE as well? I see some discussion regarding an onboard BASIC, this would lend a long way to storage for such a project. Has...

I've worked out the hardware for my 28x 8x8 matrix, but I seem to have hit on some real issues in the software. Below is a copy of my current code. To solve issues of too many keys when a key was pressed, I've added the PAUSES. For some reason, I'm getting alot of false readings when a key...

If anyone is looking for a cheap keyboard matrix 8x8 for a project, here's the hardware pinouts for the Commodore 64/VIC20 keyboard. It is 8x8 with an extra key mapped separately. I'm planning to tie this to my 28x, output to serial out. It's a zipped excel file...

I'm in need to create an 8x8 keyboard matrix. I figure the 28x will just handle the job. I'm also curious if the serial out is TTL safe to tie to other chips, or if I should shove a MAX232 into the mix on receiving end?

This might be a little offtopic, (if so please forgive) But I'm looking at creating a PICAXE controlled project that needs a smart onboard interface. Due to the limitations of the input command of the PICAXE, I thought it might be wise to add a chip to handle the userinterface side of the...

I'm curious if there is documentation on the backend programming of the PICAXE. In otherwords, if someone wanted to create a "PICAXE programming editor" for another platform where should I look for protocol information? Thanks Jeff

I'm presently using the following: serin 1,n1200,b1 which will read in a single number/alpha from the serial port. Can someone show me an example of how one could receive an entire word or phrase in this matter? Is there something along the lines of a BASIC input statement in the picaxe...

Being an electronics/retro computer collector, I quickly found a good development companion for my serial PICAXE project, an old TRS-80 model 100. I have all the advantages of a serial LCD screen (thanks to the built-in terminal) as well as a fine portable keyboard that all runs off standard AA...

I'm attempting to create an application which will allow the PICAXE to communicate in/out of the same PC that was used to program it. (IE: the same serial port) On the 08M it wasn't as much as a hassle because OUT 0 and Serial Out are the same pin. Can someone set me straight here? Also, are...

I'm attempting to create an easy demonstration of the PICAXE, so I'm looking for as "straight forward" as possible. I picked up a Reed Relay with the following specs: Voltage 5VDC Coil Resistance 250ohms Contact rating 0.5 at 125VAC Nominal Current 20mA As I understand, the outputs...

The PICAXE got a good promotion in the retrobits podcast. (http://retrobits.libsyn.com/) It's near the tail-end of the podcast. Seems I've managed to infect a few more people here in the States with "the bug" :) Jeff

I built another breadboard this evening to start workinhg on the 80x quiz project, and I guess I don't understand input pins quite right. The following program works fine on everthing except input. I'm using 80X pins, 15-18. I'm attempting to tie the pin to ground to trigger switches 1,0,7,8...

Hi gang. My name is Jeff Ledger, I'm the moderator for Petscii Forums @ http://forums.petscii.com (a retro computer and C64DTV hacking) and discovered the PICAXE while looking a recent project on hackaday.com and something someone posted to my forum. After a couple hours of reading and...
