Hi All, I have a 40X2 program that needs 2 separate interrupt routines to run one after the other to allow different input pins at different times. I tried two interrupts but it will only allow one routine. Part of the program needs to use a.0 to drive b.2 quickly on and off as necessary and...

Hi all, I'm building a 'PLC' type controller based on a 20M2 for a small chemical industrial process which a batch will take about 6 hours. It will have 4-5 switches, temperature sensor, a colour sensor (with a 18M2) and 5-6 motorised valves. There's going to be 12-14 separate steps in the...

From what I can see on the hardware page that the sweet sorter is available to buy. Is the colour sensor available as a separate item? Or do we have to use the parallax colorpal sensor from now on? Regards Mark

Hi All, I have a circuit where i have an input of 0 to 300Hz variable frequency, 0-5v square wave going in to a 18M2 and I'm using the 'count' to count the number into a variable.. I need to increase the resolution of the count to 600Hz to help with better accuracy of the rest of the code. I...

After a power cut, I'm getting 'waiting connection time delay...' when I hit the programming button. Prior to this when I hit the program button it went straight into the 'Downloading program' part. I did have a bit of trouble with the editor finding the USB AXE027 lead within the software...

Hi All, Ive got an old (restored) MK3 Ford Fiesta RS1800 in which ive changed the differential so that unfortunately the original mechanical speedo drive is no longer functioning. I do however (to keep it original looking) want to retain the original mechanical speedo. I have fitted an ABS...

Hi all, is it possible to create with a 08M2 a data stream that is a 8 byte message once every 100mS (ten times a second). The 8 byte message consist of 7 data bytes, followed by 1 check byte. Bytes are transmitted 10mS apart, with a 30mS gap between message repeat. Is this possible within...

Hi all, Im building a small rev limit or shift light for my race car. I'm still trying to get my head round this programming although my electronic skills are good. This is still work in progress but im stuck to add extra leds to the circuit in a progressive mode. im using a 18m2 on my...

Hi all, i'm a noob at the programming stuff. I used to be a TV engineer but the programming side is a challenge for me so i'm getting stuck in with this 'simple' project. I've just accuired a small scooter with a digital speedo but its in kilometers so ive done some testing and the speed input...
