I have a PICAXE application running successfully that is controlling an external device (PTS-160 synthesizer). The synthesizer uses an 8 bit digital input. Internally, the synthesizer uses five 74HCT533 latches to set ten digits for the frequency, two at a time. I've run out of I/O ports using a...

The interrupt routine in a program I've been working on needs to be faster. Besides getting a faster OLED display, is there anything obvious I'm doing wrong which is taking longer than necessary? This program controls a PTS160 Frequency Synthesizer and is working OK. The problem is that the...

Installing the PICAXE PDF printer which I downloaded today results in the following error: "Install Printer failed. - (Error 1796)" I am using Windows Vista Business SP2 64-bit on a Lenovo W700 with 6.00 GB RAM. After installation with the above error, when I try to "Print to PDF..." it says...

I am adding control pushbuttons to an existing project which has two 28X2's, each running the same code. Each 28X2 monitors serial data from a videoconferencing codec and sends serial commands to an audio/video/XVGA recoder to capture/stream everything whenever a call is received on the codec...

After removing all but the bare essentials from my project I still have the problem. The first character I send into the 20M2 through an ICL232 (MAX232 equivalent) goes through fine. The following characters are mangled. I've tried different 20M2 frequencies, different chips and different baud...

I'm sure that I am missing something here but can't figure out what it is. I thought an interrupt condition resulted in disabling the interrupt. The following example seems to contradict that. It works as expected when simulated but when downloaded into the 18M2, it doesn't do what's expected...
