    Shaving microseconds, ideas needed.

    Hi All, Some of you have an avid interest in the execution speed of Picaxe instructions, so you may know the answer already. I need to shave every last microsecond off the execution time of a routine which has the following requirement. The 'lookup' instruction is slow, but is it slower than...

    pokesfr APFCON on 08M2, have I got it wrong ?

    Hi All, I've got a cunning plan, but in order for me to try it I need to twiddle the 'APFCON' bits in my 08M2. APFCON is in Bank 2 at address $11D ( I think ). When I try this code, PE6 says No ! pokesfr $01011101, $00000000 ' Poke APFCON Have I got the address built wrong, or am I on a...

    OLED AXE134 command (254,14) turns the cursor ON, but which command turns it OFF ?

    I've looked at the Winstar datasheet, but I'm struggling to understand the cursor stuff. The AXE134 lets me turn the cursor on, but is there a similar simple command to turn it off ? EDIT : I've sussed it out, (254,12) ! cheers, Buzby

    Drum machine. It's not quite a Roland or a Korg, but not bad for few hours effort.

    Prompted by Chris' virtual buffer thread, and my recent acquisition of an AXE134 OLED, I decided to build a ( somewhat limited ) drum machine. Most of the code is for the user interface. Two buttons move the cursor to select the buffer position, and a third toggles the data at that point...

    PE6 Simulator, OLED does not simulate cursor.

    I've finally got me an AXE134 20x4 OLED display, and was interested to see it has a cursor facility, very useful. However, the OLED simulator does not seem to replicate this function. Is this a bug, or am I doing something wrong ?. Cheers, Buzby

    Has anyone tried ultrasonic distance measurement by PICAXE alone, not using SRF005 etc ?

    Hi All, I'm tempted to try building a location system, a sort of cut down version of the one I linked to a couple of years ago ... The basic idea is that two devices at fixed...

    URF/ERF remote programming nearly working, but not fully.

    Hi, I need a remote programming facility for my current project, so I dug out my URF and ERF. The URF/EFR link seems to be working, I can do a firmware check OK, but programming is not working properly. Small programs load OK, but longer programs time out with a 'Compiler has stopped...

    OT: Bluetooth audio transmitter needed, Googling gives confusing results.

    Hello All, Can anyone suggest a board that accepts an audio input, then transmits to a standard Bluetooth speaker or headphones ?. I want to add this facility to an existing, somewhat vintage, record deck. Google, eB*Y, and Am***n all give hundreds of confusing results. Many say transmitter...

    PE6 Simulation of 'serrxd' , is it broken or am I missing something ?

    When I use the simulator to enter a number via serrxd, it seems to enter a 0 automatically the next time the program uses serrxd, before I even touch the keyboard. If I use a real chip it's OK. What am I doing wrong ? Cheers, Buzby

    28X2/40X2 Othello / Reversi, basic skeleton code

    Here is my start at an AI game playing machine. It needs a 28X2 or 40X2 to run. ( It will run in the simulator, but it's *very* slow. ) It's a bit rough, no proper 'end of game' detection yet, and it's not very intelligent. The final aim is implement minimax, and fit the code into a 20X2 ...

    Can we have a new Serial Terminal please ?

    The Picaxe Serial Terminal is my no.2 tool for debugging,( after the simulator ), but sometimes I have to use a 3rd party terminal if I need a bit more control of the screen. This entails using up another USB port, another cable, and forever swapping. It would be really useful if the PE...

    PE6.1.0.0 #Slot 4 on 20X2 still not working.

    I'm working again on my project which requires Slot 4 on a 20X2. PE6 was being a bit too much of a nanny, and told me there was only Slot 0 on a 20X2. The latest PE revision notes say this issue is fixed, but maybe only in a beta version of the compiler. Do I need to install this beta version...

    Does anybody recognise this ?

    This was in my pictures folder of holiday snaps from Turkey, back in 2007. Anybody know why ? Is there a PICAXE in there ?

    VL53LOX, has anyone tried using it with a PICAXE ?

    Hi All, The VL53LOX 'Time of flight' range sensor looks really attractive. It's got 2m range, needs no special target, and interfaces using I2C. So I bought one, then read the datsheet. ( Some here may notice I got this sequence back to front. ) This when I found the datasheet doesn't have the...

    I reported this issue way back in PE5 days, September 2012, but it still seems to be with us in PE6, this time with no increment at all !. Cheers, Buzby

    LED strips, are there any real white ones, not RGB ?

    Hi All, I want a LED strip that can do individual control, like the APA102 based strips, but I want all the LEDs to be 'warm' white, All I can find are RGB strips, are there any single colours equivalents ?. Cheers, Buzby

    Making downloads faster, I've seen it somewhere, but where ?

    Hi All, There is a method in Windows to tweak some USB or serial parameter somewhere which can speed up downloading. I'm sure I saw it on the Picaxe website, or in the docs maybe, but I can't find it now. If I remember, the tweak makes it faster, but less stable. Any pointers ?. Cheers...
