Hi all, sorry for the maybe confusing title but I have been looking a while for an affordable display that can be used with Picaxe chips W/O consuming 8 datalines. One option was the usage of a LCD driver that can accept RS232 (ttl) signals, but these are 10-15 € more expensive becouse of these extra hardware.
But a few days ago I stumbled on the DOG-SERIE LCD displays from (http://www.lcd-module.de) These modules come in various colors (normal and inverted) with optional backlight. And best of all they can be used with 4/8 bit, SPI and I2C and run from 3.3 to 5v!
I have tested the (DOGM081W-A) 8x1 chars with SPI. I used them with a 08M to show some messages with 3 wires. (normally you would need 4 but you can also pull it off with 3) I didn't need any other hardware, just the 08M and the LCD. The price for the LCD was about 15€.
I'm verry happy about these LCD's and how easy they are to implement in a Picaxe project. So I thought I'll share my finding with the other picaxe users.
greetings
