Changed symbol outputs to pinb.6, pinb.7, pinb.8 so everything is hunky dorory now. symbol redled=pinb.7 ;pin 13 on chip symbol yelled=pinb.6 symbol grnled=pinb.5 Many thanks as I am now rolling on this simple block signal conrol fro HO train

Thanks, that fixed the problem. Don't understand why inputs have to be pinb.0 yet outputs are simply b.6. Maybe I will try as pinb.6 for consistency later, but it is working. Many thanks.

I am converting some simple ode from 08m2 written years ago to 18m2 chip. My 1st if statement fails on 18m2 but works on 08m2. What gives, I will try to attach code. Some other problems exists but I need to get by this if statement error. #picaxe 18M2 ;define chip type ; symbol...

After much digging thru manuals and on line examples, I think I have got it. Thanks

I have been away to long so my brain seems to have lost much. I have a program working for my 8M2 but now I want to use the 20X2. Problem is I get a syntax error if inblck=c.6 so whats wrong ? . #picaxe 20x2 ;define chip type ; symbol redled=2 ;pin 5 on chip Output pins for led lights...

When I use sertxt in this program, the first two ascii charcters are messed up. But if I create a simple program to test the sertxt at the same baud rate it works ok. I have tried many variations, but the first two characters are messed up. This is what comes out on the terminal display: I have...

I am fiddling with a project that is going to require fast execution beyond what my current PicAxe chips are capable. I wish Revolution provided a true compiler/assembler. It could be configured to only work with PicAxe chips by assuring the chips be preprogramed by revolution (as they are now...

I seem to have lost my mind. I can't figure out how to write a complete 8 bit byte to port b.0 thru b.7 on a 20x2. Spent some time going thru code reference manual and can't find it. I can read a byte from EEPROM, so how do I output that byte directly to a port (for speed) The below code has...

I also use Win10 and MS Edge. Problem seems to be gone , for now. Only a test below, yes it is still working.

Here are unedit shots of the write cycle between AD which is very fast, about 1.8 us. But dot data is updated about every 30 us. First screen capture shows write time between two AD is 1.8 us.v Second screen shows dot position update is about 30 us. I am guessing the write time between the A B A...

In another thread I have been posting jpg & bmp pictures most of the time without a problem. Now it won't let me post even pictures that I posted earlier without problem. Things I tried: Turned off firewall turned of all security programs tried advanced posting . It looks like it uploads (blue...

Well, I am going to skip the shifter circuit, very simple, will come back to later. Now I want to examine the character formation provided by the dual DAC signals. Here is a capture of the wr, a/b select, and a few data bits. AD write occurs going low. Click on icon to expand . The write to...

Like so many projects I start, once figured out and tested I tend to lose interest. Just rec'vd my new logic analyzer (LA2016), so interest has been boosted. Here is a screen shot of the two programmable resistors (MCP4132 10K) being fed data from what will be a picaxe 08M2 eventually. . (Click...

Now that I have the circuit board figured out, I am going to try substituting PICAXE chips. In the block diagram the micro. The attached block diagram shows the pinouts that are currently out of the microchip cpu's, with the substitution PICAXE chips shown below. First evaluation it seems they...

Same problem, never finish to look good. But now I have a laser cutter (plastic and wood) and can make great looking enclosures or control panels. Built a working wood gear clock, both in wood and plastic, and it uses an 08M2 driver/timing chip for pendulum swing. The red plastic panel was to...
