    Storing and retrieving large values and reducing code space.

    Hi all, I am using a Picaxe 20x2 and am trying to add multiple 16 bit values and have come up with the following code. I'd be interested to know if what I have come up with is a reasonable way of doing it or not, and if there is anyway I can improve this code to reduce program space consumed...

    HPWM switching between half bridge and single mode on the fly

    Hi all, I read that running a new HPWM command resets the internal timer and may cause glitches if already running a HPWM output. I am running a Picaxe 20x2. I am running a synchronous buck DC converter, and would like it to change between Buck and Synchronous Buck modes on the fly. The...

    Picaxe 20x2 no Hardware PWM mode 1 on early models?

    Hi guys, I have recently had to delve into my stash of older Picaxe chips as I had burned out my newer ones (don't ask) - These are probably circa 2010 I have found that HPWM Mode 1 is not working correctly on these two older chips. The 'high' side output is working on Pin c.5 but there is...

    Picaxe 20x2 >16MHZ AXE033 problem

    Hi all, I have taken a look at a few forum threads here that talked about problems with serial related communications with the Picaxe 20x2 running at higher speeds. My particular problem - I have a Picaxe 20x2 (on a very steady 5v well filtered & regulated supply) I have a AX033 LCD display...

    Picaxe 18X Freeze / Locks up

    Hi Guys, I have a real problem with Picaxe 18X locking up/resetting itself mid program. The circuit itself is a maximum power point tracking solar regulator - basically an efficient buck dc converter with a constantly rapid changing duty cycle. The picaxe itself is on the low voltage...

    28x and PWMout question?

    Just a quick check - the manual specifies that on the 28x the two PWMout pins use the same internal timer, therefore their period is the same. Can you have both pwmout pins running simultaneously at different duty cycles?

    Can you control PWMOUT on a slave picaxe

    I know you can use serout to control pins on a slaved picaxe, connected by an output pin on the master, to a input pin of the slaved picaxe. If I had say have a master 18x that I wanted to control a 08m as the slave. In this instance I dont simply want to control pins on the 08m, i want to use...
