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...

I've used the circuit shown with no problems. The code in both 28X2's includes: pullup %00101000 ;enable internal pullups on B.3 and B.5 The code is written to use a single button to switch between two states (enabled/disabled) on each processor. But when both buttons are pressed at the same...

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...

He said "#include" . . . heh heh. ;) The bees have been very busy indeed.

US$30 PICAXE "Web Server" Here is the program from my previous post but without the code for the DS1307, auto-refresh, or data-only mode. This reduced size version of a US$30 PICAXE "Web Server" should be simpler to follow and easier to modify. Also, this one uses CSS to format the...

Another example. I've been fooling around with a WIZ110SR and botsmaker's code. Here is what I came up with for testing. It's pretty rough but serves as a good starting point for me, and hopefully others. Here's what it looks like in Firefox and IE:

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...

If you had a math co-processor (or a lot of time to get really creative without one) you could:

My board is slightly different than what is shown on the schematic. (No resistor between battery and RTC, etc.) But connecting it up by following this schematic still worked quite nicely. I bought two of them. One keeps time very well, the other gains about three minutes a day.

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...

Thanks for the very useful responses. I'm not sure what was going wrong. I made final tests with and without the 'settint OFF' statement immediately before my post last night with the results as described. Then I threw a towel over it all and turned in. This morning, I tried the 'SerTxd' method...

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...
