Hi Im new to ths forum so please excuse if this post is in the wrong place.
I am attempting to create a countdown timer using an OLED screen and picaxe.
I have bought the following:
PICAXE-18 Starter Pack
Serial OLED Module (20x4)
I have assembled the components. I have run a test program with an LED on my picaxe board to see if it work, which it does.
My question is how do I connect my OLED screen to the picaxe board.
http://www.picaxe.com/docs/axe134.pdf
The instructions say to connect the positive and the ground. for which there are several port on the picaxe board. I used the positive and the negative ports on H0 next to where the battery pack is connected. As for connecting B.7 to INT. The B.7 output port is comprised of a negative and positive port. which one do I use?
I connected the negative of B.7 to the INT of the OLED module. When I turned it all on with this code.
init: pause 500 ; wait for display to initialise
main: serout B.7,N2400,(254,128) ; move to start of first line
serout B.7,N2400,(“Hello!123”) ; output text
end
The OLED didnt light up or seem to be on. Have I connected this up properly? I have looked for an actual picture of the serial OLED and picaxe board wired together but cannot find one.
What do you all advise / suggest?
Many thanks,
Pete
