Hi Guys,
Now that I have got my rs232 logger working well, (http://www.picaxeforum.co.uk/showthread.php?t=11681&page=3) I want to add a 40x4 Character HD44780 LCD to the "bus". In other words has someone used a 28X as a serial to parallel lcd driver? The PC would be sending the LCD the text.
I know it's a bit of an overkill for a 28X, but I have one here and it seemed like a good place to start.
I was hoping for a simple 2400 addressing scheme where I could send it say for starting to print on line one: "lcd1,1,This is the text as a string for line 1"
and "lcd2,2" to send it text starting at line two character 2.
Something like that, as most of the serial to parallel converters I've seen to buy will just send what is coming out of the serial port, where as my "rs232 bus" already has traffic (text) on it so I need to be able to get the LCD to listen for it's own code like "lcd1,1" before printing to screen.
Has anyone tried something like this before?
Cheers
Bj
