I am having a problem with the serin command in the attached program, it seems to hang waiting for input. The Picaxe is (should be) communicating with a PC application running an optical disk. If I comment out the serin lines the last bit of the program, with the remote input sending commands...

I have a project where I want to use a PICAXE as a dumb terminal interface to an application on a PC which controls an optical drive. The control commands are simply "P" for play or "S" for stop which I would like to instigate from a PICAXE remote control using infra red. Mode and track status...

I know battery charging has been covered before but I think I am looking for something a bit different which I don't think has been covered before and I would like some help in possible ways of achieving it. The application is to fast charge a series connected 6 cell battery pack for Radio...

I asked for help getting an exponential curve but it turns out what I needed was a log curve and reverse log curve. The simple solution I was given basically boils down to making the input ADC voltage look like a log pot which is variable. Can anyone think of a way of mapping the input voltages...

I would appreciate some thoughts on a problem I am looking into. Starting with a straight line response graph where a voltage level read by READADC or READADC10 is passed to a PWMOUT, I want to be able to change the response graph to give various exponential curves, up and down. I could do it...

I am trying to find a way to receive tag numbers from an RFID reader at up to 5 a second, attach a time stamp to each one and buffer them ready to send to a PC without losing any! The reader has an RS232 interface which is configurable as does the PC, all data is ASCII. I was thinking that the...
