I agree about math - this has probably been the reason number one to look elsewhere. However, just adding a 'macro' style function would not solve the problem for what I'm working with. I can do that with current tools, but it is normally too slow for the kind of tasks we give micro-controllers...

This is one of the reasons I posted the question - microchip has updated their range with drop-in replacements for the chips that fancy picaxe firmware. Given, to use some of the new stuff, there would need to be new firmware, but this must be 'next version' kind of thing, rather than coming up...

Dear PICAXE team! Every now and then, somebody asks if there is a chance of a new and improved product from PICAXE. Namely, a new chip, an improved software version or something. Now, I decided to be this somebody, since I logged onto the picaxe page after a while and I can bet the 'news'...

It was/is for running a model car, the main engine. Since I'm running half-bridge mode, there is about 100 speed 'steps' each direction with stop being 127+-20 as the current is just too low for the engine to run in either direction very close to 127. It works very well now, the code is in the...

Thank you, team :)! Understood, no problem to work around, of course. /Edmunds

Dear all, I'm confused about this code ignoring pause 16000 between TestFWD and TestBWD subprocedures of newmain: in the file below. Can anyone spot what is wrong with it? Thank you for your time, /Edmunds

Ok, makes sense, thank you :) /Edmunds

Dear all, I'm configuring PWM with pokesfr, since I need to route around timers and use different pins than the defaults for picaxe firmware. 8 MSBs of duty cycle are stored in CCPRxL register and the remaining 2 LSBs are kept in bits 5:4 of CCPxCON register. Since the bits around 5:4 in CCPRxL...

Ok, seems like I was wandering down the wrong path. I'll keep playing with inductive/hall options then. Thank you all for your inputs, Edmunds

Or, perhaps, inductive like here: https://www.mdpi.com/1424-8220/11/11/10522/htm ...

Dear all, Would it be possible to build a capacitive linear position sensor around picaxe Touch functionality? I'm thinking something like digital callipers, but a good 20 times smaller. To detect 10mm position with accuracy of 0.05-0.1mm. I realise that would require custom PCBs, but that is...

Dear James, Thank you for your interest. I have since dropped the line-following project as not perspective. I have used many of the techniques and learnings, however, to design the 'magnet follower'. There are a couple of threads devoted to this on the forum, so just drop 'magnet follower' in...

Dear all, While working on a project, I came across Analog Devices AD7380/7381. It is a 2ch ADC converter, but the trick is, it has oversampling and averaging built in. This can be a great advantage for some projects where ADC readout can benefit from some digital filtering (say, averaging)...

Hey, my identity is back! AllyCat - I used exactly what you are proposing, but for some reason it did not work. I did not have time for longish investigation, so it might be I still did something wrong, but the preload I calculated (the same number as yours) threw servos in all directions...

Dear all, Thank you all for your inputs. I worked for some time more on it last night after posting and I have something like this that works: #macro EnterSleepMode() low D.7 'STSPIN220 EN low to save power and reduce heat low A.5...
