Picaxe Analogue Calibration Board - replacement firmware

I thought I would share replacement firmware for the Picaxe Analogue Calibration Board.

http://www.picaxe.com/docs/BAS810.pdf

The board came with a very old part the 16c710, well mine did, and it failed this morning.

Replaced the fail part with a 16f1847 (same pinout) and ten minutes later new firmware. Simple compile for your selected part, you do not have to use a 16f1847 as most 20 pin parts would work - I just recompiled and tested a 16f88, and, that part works by only changing the chip specification.

Anyway, for this legacy board. which I use daily. A replacement firmware for the you to enjoy. I have added a feature.... when you power the board the startup ADC value sets the time period between ADC samples. :)

That's very interesting.

What would be more interesting?

Make it a 10-bit project (somehow.)

0 - 1023. That's all I use.

Easily done. We have a three 7-Segment displays - if you are ok with ready HEX 0-3FF that equates to 0-1023. I

I can post the code in a few seconds - if this is of any use.

I have posted two more versions giving three.

1. A plug in replacement for the original firmware.
2. A 10bit version using HEX to display values from 0 to 1023 as 0 - 3FF.
3. A simple voltage meter with a range of 0v to 5v. This uses the 10 bit ADC and then scales to 5v to proportionally provide the meter. You can adapt this version to show other ranges like 0 to 999. Your call.
