I worked only a year longer before I hung-up the apron (IT 30+). Even years later I'm still called for solutions to system problems. I'm only a newbie here using these great little chips, but I've always liked your code snippets and comments. Good Luck and the best of health in the coming...

Thanks for the link to Universal-solder. I didn't know about them and only a 6 hour drive from home, 8)

Be careful using this module. Mine came with a CR2032, not the rechargeable one. I just moved this resistor (201) to disable the charging circuit.

I've been given a hand full of these (DS18B20) temperature sensors. They are known to be counterfeit. During testing with readtemp12 they are all resolving 11BITs or a step of 0.125. This could mean the EEPROM has been set or the configuration register cannot be written to. I've probably...

I have the same issue with macros. My only solution, was to make it a regular subroutine to debug. Another thing with macros is they can use up a lot of memory, so I try to keep them short and to the point.

This is a DEMO of a PICAXE 08M2 using a PCF8574 I2C 8-Bit I/O Port Expander driving a standard 20x4 Blue LCD display. This code is part of a library that will be used for a future build (or re-build) of a QRSS transmitter. The transmitter frequency will be created from a SI5351 I2C configurable...

The ease at which to program the PICAXE is truly astounding. I thought a Morse code generator would be a “NO BRAINER” but was caught off guard. There are so many different ways to create this type of code. Most programs need the user to map the ASCII to a binary code to create the data...

Purpose: Use the IR remote to enter a number from 1 to 65535. Data to be sent via the Sertxd to a terminal. Originally, this code was written to command a vintage Kenwood TS-680S radio to QSY (change to another frequency). I only needed to be within a kHz from 500 to 53999. Numbers...

DUH!, I must have missed something, somewhere. I just realized that you can nest #define, cool. Sorry for being a bit slow. :geek:

THANKS for schematics! This old thread still useful. I was really wanting the AXE091. There is one supplier in this side of the pond, but had to be put on a waiting list. Guess what I found at a local HAMFEST! A complete AXE091 PICAXE Experimenter Kit (SERIAL), yup! DB9...

Just for your information, Here is a neato-cool way to convert images into byte arrays (or arrays back into an images) for use with (monochrome) displays such as OLEDs. image2cpp LINK: https://javl.github.io/image2cpp/ CODE is standalone Open source and runs on a single web page. GitHub...

Thanks, Just lookin' about for FREE software to draw schematics. Not to use old stuff. Currently I use Adobe Illustrator, which can be a pain-in-the...

DesignSpark PCB Link on the free software page doesn't work. Displays Secure Connection Failed. Editing (re. hacking) the link take you to https://www.rs-online.com/designspark/pcb-software. Is this the same software? Doesn't look free. Oh I haven't yet search the site. There seems to be a...

Hippy always has the fastest and minimalist code ever. Works for me. An OLED (SSD1315) dump of a few bytes on Page 0 from the 24LC16B connected via I2C to a 08M2.
