    Wireless programming ?

    @Goeytex Yes a disappointing result for the HM-19's and much the same result as with my HM-10 fakes. Keen to try some NRF24L01+ modules! Keep us posted Goey! Cheers, Kurt

    Setbit after AND/OR

    That sounds like a logical way to do things and well worth adopting @inglewoodpete (y)

    Setbit after AND/OR

    I have just discovered that you can only individually address bits up to bit31 (b3)...Is that correct?

    Setbit after AND/OR

    Thank you for the solution @inglewoodpete and @Jack Burns. I wasn't aware that you could address bits directly like that, so you learn something new everyday. For a "new member" your on top of it Jack (y) This will free up half a dozen word variables at least! Thank you again! Cheers, Kurt

    Setbit after AND/OR

    Hi All, I want to use this particular line in a project: "if b2 bit 0 set and b2 bit 1 clear and w14=1000 and pinC.4=0 then gosub dim" Yes i realize my code is convoluted but this is the extent of my programming skills 🤣 I have been using whole bytes for 1's and 0's which is probably a waste...

    PICAXE40X2 Nixie Clock

    Can I suggest you use the DS3232 RTC, Its ultra accurate and stable only losing seconds a year unless of course your updating via a network each day. Easily integrated via IC2...

    40X2 hardware interrupt

    You need to re-issue the setint command AGAIN after the command has been executed and processed.

    Wireless programming ?

    Yes the programming is relatively slow compared to using the cable method but considering the great availability of the HC-05 bluetooth modules (and they're cheap) which can do a FULL download in just over 3 minutes, is it really worth sourcing more exotic, expensive and harder to find modules...

    Wireless programming ?

    @Goeytex Update! Tried some other bluetooth modules I had laying around and the results are very disappointing! They were advertised as HM-10 but it turns out they are fakes. The HM-10 modules report as MLT-BT05 V4.4 so an updated firmware than my other HC-05's which report as MLT-BT05 V4.0...

    Wireless programming ?

    @Goeytex Your humility is admirable, yes the general principle is fairly basic but if it was that easy to implement the solution would have been all over the forum years ago.... I have measured the time between bytes (I hope this is the correct method) as being between 39ms & 53ms, this varies...

    Wireless programming ?

    @Goeytex Success! I've managed to wirelessly program a 20x2 picaxe with 3894 bytes. A few modifications to your code using two 08M2's and two MLT-BT05 4.0 bluetooth modules as Master/Slave configuration. Download takes about 2m40s, so not ideal if your in a hurry but well worth the...

    Wireless programming ?

    @Goeytex Thank you for the clarification RE: picaxe programming baud rates and inversions. I always thought it was 9600. My apologies but i have incorrectly named the modules I'm using. They are correctly MLT-BT05 4.0 which i think roughly translates into HC-05. I have successfully paired them...

    Wireless programming ?

    @Goeytex I've been experimenting with some bluetooth modules (HC-O6) and wanted to verify baud rates. I note in your code that the 14m2 is monitoring the response code from the target picaxe at 4800 baud. Is this what both the modules should be set to? The "regular" usb to serial cable is set...

    Wireless programming ?

    Goey, Mate, what an excellent piece of work! Can't wait to build your circuit and test... I've decided that Bluetooth would probably work best in my situation, seeing that its only about 5 meters from my computer to the current project in use and I like the idea of the sort of "secure" system...

    Wireless programming ?

    Yes one 14m2 handling everything would be ideal...Just my 2 cents

    Wireless programming ?

    @Goeytex I think that would be an essential addition to the design. A couple of extra transistors and an extra pin on the 14m2, no big deal for the enormous benefits it would bring...

    Wow...This is getting exciting, excellent work Goeytex!

    Wireless programming ?

    I'm using this usb to serial adapter to connect the bluetooth modules to the pc. I have to invert the output at the receiving end using a 74HC04 hex inverter. The experimenting continues...

    @Goeytex I have the clone of a clone of the real one...:LOL: When queried the module reports as a MLT-BT05 4.0 Yes the HM-10's are the real ones...

    That's it...I'm getting the bluetooth modules out and giving it another crack...😁 Thank you for the inspiration guys!
