I haven't used Picaxe for quite a few years and am trying to get back into using Picaxe by using an Axe201 (28x2 module). I had a few questions.
1) In the Manual 1, page 49 , under Testing the System there are instructions for testing a simple program by turning on and off an LED. However, the instructions talk about connecting to either directly to a chip on a proto board or a project board. Which is my 28x2? There are 2 drawings but I am not sure which way to connect the LED and 330 ohm resistor.
2) I mis-read the page regarding the orientation of my 28x2 and didn't realize the chip was 180 degrees the other way around. Hence, next question :
3) How do I check if my 28x2 is still OK. Upon doing a search on the forum I found a reference to doing : View, Options, Check Firmware but this does not work with PE6. Is there a way to check my 28x2? The onboard LED still lights up (I wired it to 5v) but I cannot get an LED on pin B.4 to flash.
4) If I wanted to switch on and off the onboard LED (pin 3?) how would I program that? It doesn't seem to follow the standard Port.Pin convention. On page 2 of the Getting Started document it says I could connect it to an output pin but would I have to use a 330 ohm resistor?
Any help would be greatly appreciated.
