Time for some help. I'm counting pulses using an 20m2. Every thing was going fine for a couple of days and then the count was suddenly off by about 300, plus the count started jumping around about +/-40 counts. I'm using a pulse generator to act as a counting source with a frequency counter...

The program runs fine on an 18m2 but when I down load it to an 20m2 it doesn't run. It's a simple clock program and I've made sure the SCL and SDA are on the proper pins of the 20m2. There are no other connections to the 20m2, just the SCL and SDA. I've Tried different setfreq, but that has...

This program is fully commented, explaining how characters are created and transmitted to the display. A clock program is used to do this. The time, date, day and AM/PM are incorporated, along with a line of text. There are, no doubt, other programs much more efficient than this one, however I...

Picaxe 18m2, DS1307 (stand alone chip with crystal), communicating to display and DS1307 over 12c. The seconds, minutes, hours, date, and month all read back properly, however the year only shows the last digit. If I set the year as $20 I'll get one zero (lsd )read back to the display. What's...

I've got an 18m2 connected to an oled (128 x 64) display and also a DS1307 clock (just the chip not a module). With ONLY the clock chip connected to the bus the clock portion of the program works fine (display portion is disabled). I can see the seconds, minutes etc. incrementing on the debug...

This program was originally created by paraglider_nut. I added more comments and also a variable data section, wich I believe was created by Hippy. I also added a "top of page" subroutine, as the program did not always start at the top of the display and was also scrolling left to right, one...

I copied the attached program from the forum. The program was written by paraglider_nut. Being new to oled displays there are a few lines of logic I don't understand. I went through and commented what I could understand. All the lines I don't understand I placed a question mark after them. To...

I was wondering if anyone out there if could give me a hand with this. I connected a picaxe 18m2 to a DS1307 module. Downloaded the program and ended up with nothing but 255's in all the memory locations. I read somewhere in the forum that the DS1307 might not be working, if that happens, so I...

The attached schematic shows how to have a picaxe turn on and off its own 5vdc supply. External components: H11B1 opto isolator 2N2907 transistor 10k resistor 330 ohm resistor

I'm running this simple program on an 08M. Main: high 4 high 2 wait 3 low 2 wait 3 low 4 end I'm assuming that on "power up" the 08M starts running it's program immediately, yet it take eight or nine seconds to start running. Am I missing something in the program. I've worked with 08M's before...

Attached is a PDF of several schematic showing the wiring to connect the steppers and also the programs: One 21-02485-03 stepper being directly controlled/driven by an 08M Picaxe. One 28YBJ-48 geared stepper motor being controlled by a 08M Picaxe and driven via one ULN2003 chip. Two 28YBJ-48...

Maybe someone can shed some light on this. I'm running two stepper motors using an 20M2 via two ULN2003 boards. You know the ones with the LED's' and connectors. I'm controlling the steppers by doing in a typical "high b.0: low b.1: high b.2: high b3 then a pause. This is done for every step. I...

I was wondering if someone could explain this phenomena to me. I have a picaxe 08M running a stepper motor. The programming cable is connected from my laptop to the 08M serial port. The 08M program is running fine. When I turned on my laptop (windows XP) the 08m program stopped running for...

Of my searching on the internet, I could find no info. on how to connect/program a picaxe to a small printer. The guys on the picaxe forum helped a lot, as I am no expert. There is also an LCD program. All the programs have been tested using the PDF wiring schematics. KEEP IN MIND, THE PICAXE...

I was wondering if someone could give me a hand with a program. What I have is 40 character (page width), parallel input, kiosk printer. it's been around since 1995. The only usable signal lines are the eight data bits and a strobe line. I have no problem sending text to the printer and it...

I was looking at a program in the forum and I'm stumped as to what these numbers represent or how they are derived. The program stores the ASCII values for letters and numbers, in the onboard eeprom, for use in an LCD display. I can understand just storing the actual ASCII value, but I don't...

I've installed the Picaxe PDF printer software, but it does not show up with the rest of my printers. I have a Windows 10 system I'd like to use it to view the .bas files stored on my computer instead of having to start up the Editor.

This is my first post, so I hope I'm doing this right. I used a longer version of this snippet to put text on the first line of the display and variable numerical data in the second line of the display, for a Geiger counter I built. This snippet uses all eight data lines of the display. I used...

This is my first forum experience. I've done some projects using a picaxe before but I've never used the "count" command and I'm having problems. I'm using a 20M2 to count pulses from a Geiger counter. The program works fine, except the "Count" command isn't putting the count into the variable...
