Hi guys, I have a problem with output pins not behaving as expected. To help you understand my dilemma I've attach a schematic and show my code below. My project is using a PICAXE-40x2 microcontroller to 'read' the state of midi music notes from a commercial Midi file reader. The Midi file...

I am using an hardware interrupt to read the state of 8 input pins on PinsC. Whilst in the Interrupt routine is it possible to then invert that state and put that into 8 out pins on pinsD? Cheers,

Hi folks, What is the minimum reliable imput signal duration the PICAXE -40x2 is capable of reading? I am using a 40x2 to read up to 8 midi music notes as input signals. The duration of these notes are approximately 125ms. Would the 40x2 running at 40Mhz be capable of reading these? I have...

I want to read an input from a darlinton driver source but I am having problems with the output of the darlington not going low enough i.e. down to approx 1 volt and not zero. This is not low enough to trigger my PICAXE - 28X2. Is there a simple way of converting this 1 volt to 0V? Any help...

Hello everyone, I am a total newcomer to the PICAXE Microcontroller world and to this forum. I have an AXE020 Project Board fitted with a PICAXE -28X2. With the board powered up using the common 5v link what output pin voltages should I expect to see when set by the program to 0 using the...
