    Fastest possible ADC response?

    I haven't ever looked at the comparators or DAC, but for going from active low to high impdence state, could you use an N channel FET or NPN transistor to pull the signal wire to ground and then switch it off to go open circuit (up to the breakdown voltage of the component used)? This would be...

    28x2 MPPT Success, 50v 35amp ,2.1Kw Panels

    Looks like they are quite productive systems in terms or outputs. I have been uploading our smaller 2.2kW system (NottingHillTestSystem) by getting data from the inverter's RS232 port. The first version of that had an arduino acting as a controller and baud rate converter to an old router...

    28x2 MPPT Success, 50v 35amp ,2.1Kw Panels

    That would make a bit more sense as I was trying to work out how it was calculating the MPP :). I see in your original code you are uploading / have made allowances for uploading data to pvoutput. Is this done through a usb-serial converter and a small computer or something fancier? Looks like a...

    08M2 PV MPPT Charge Controller

    Hello, If you are interested, I have come across an even more simple style of mppt, however you may class it as a pwm or hybrid between a pwm and mppt. I used to race model solar cars (10W panel with no energy storage except for the momentum of the vehicle, >30km/h top speed around a 100m slot...

    serin/serout baud values with setfreq 32

    The copy of the manual I have from the Programming Editor V6 has it further down the page under the for all other parts heading as it doesn't apply to older chips - see attached screenshot. If speed and or processing time between receiving bytes becomes an issue, the hardware serial might be...

    Python preprocessor script for #includes and compiler selection

    Hello, I have been playing around with getting #IF, #IFDEF, #IFNDEF, #ELSE, #ELSEIF, #ELSEIFDEF, #ELSEIFNDEF (I know this isn't in the manual, but it was easy to implement), #ENDIF and #UNDEF to work and have submitted a pull request. No pressure or rush to get it approved - it is a busy time of...

    Old RTTTL Ringtones

    Seeing this thread reminded me of some of my earlier attempts at getting rttl ringtones to work. Personally, I had a fair bit of trouble getting the wizards to convert the ringtones into something that sounded even vaguely familiar, so in the end I attempted to write a Musescore 3 plugin to...

    Python preprocessor script for #includes and compiler selection

    I have submitted a pull request, so hopefully it works correctly and you get it. Feel free to try and break it / test it as I have only tested it in situations I would commonly use it with or know about and with a limited set of files, so there may be issues that have not been found yet...

    Python preprocessor script for #includes and compiler selection

    Thanks for that. First time using command line git to push directly to github, so must have entered an incorrect username or password or something :) I have copied the various extra features from mine into your code and it seems to be mostly working, although I think I have broken some of the...

    Python preprocessor script for #includes and compiler selection

    Ok. Good to know that there are others out there and thanks for sharing it. I have to admit that I didn't go looking too hard for any previous / existing ones as I thought it would be a fun challenge to start from scratch :) When I get time, I might copy the chip selection and starting the...

    Is PICAXE support for Mac officially dead?

    The fact that you are getting the compiler to start well enough to complain about line endings would say to me that you are close :)

    Is PICAXE support for Mac officially dead?

    I had the same issue with the ^M in Linux. I think it is the carriage return that is added in Windows as an extra character in line endings that for some reason won't work on other platforms and must be filtered out in the Programming Editor and or Axepad before it is passed onto the compiler...

    Python preprocessor script for #includes and compiler selection

    Hello, This is my first post, so please let me know if I have done something wrong in regards to the forum. I recently made my laptop dual boot Windows 10 and Ubuntu and have found that the picaxe preprocessor has been one of the few remaining things requiring me to boot into Windows due to my...
