When trip1 goes low it initiates the flashers and sets output B.3 high as it should. When trip2 goes low the flashers continue as they should. However when trip1 goes high again (simulates a train has passed) the program jumps back to main, even though the conditional statement says that ALL...

When I type in the following code, the program compiles without issues: dirsB = %11111111 dirsC = %00000000 setint %00000011, %00000011, C but when I try to add C.4 into the mix like so: dirsB = %11111111 dirsC = %00000000 setint %00010011, %00010011, C I get a syntax error. Why is this...

I want to use the PICAXE-18 High Power Project board to demonstrate control of motors using a keypad. My plan is to transmit the characters from the keyboard using a peripheral processor (08M2). My question is can I use pins C.3 and C.4 as my serial Rcv and TxD pins, or are they reserved...

It is my understanding that the 18M2 chip has two separate timers which allows using pwmout as well as the servo commands. My question is this: If I am generating a PWM output signal on Port B.6, can I use any PortC pin to issue a servo command or must I use Port B.3?

After reading through the manual, I infer that the 18M2 has additional dedicated internal timers that allow the pwmout and servo commands to work together. The channels available for pwmout are B.3 and B.6. Am I interpreting this correctly?

Hi I am working on a robotics project which employs 4 servos operating sequentially. In order to check the operation of the servos and to set the travel limits I wrote a simple little program to perform these operations. Except things are not as simple as they seem. Originally the program was...

Once I added the L293 board and motor I have been killing my 18M2's. There is no magic smoke, but the program doesn't drive the motor like it should and when I try to re-program the chip I get a "hardware not found" error message. I did modify the CHI030 board by replacing the Darlington...

Can pinC.4 be utilized as a digital input? The reason I ask is that for some reason the simulator will not allow me to toggle it hi/lo. I am using all the other pinsC except C.3 as inputs.

What I want to be able to do is toggle between auto and manual modes using the “A” button on the transmitter. When in “auto” mode, the servo should just rotate slowly back and forth. When in “manual” mode, I should be able to move the servo left and right using buttons “B” and “D”. However...

When writing code do we use the shield nickname pin reference (e.g. S.A1) or the actual PICAXE pin name?

I just received my new data logger and hooked it up per the instructions. I am using an DS18B20 input sensor and a AXE133 real time display. I also have the AXE034 clock and 24LC256 EEPROM. I am using PICAXE editor 6.0.7.5 Here is the problem: I open the editor and select NEW program. Next I...

I breadboarded the attached circuit and hooked it up to an AXE132 which I mated to a 16x2 HD44780 Character LCD Display Module that I got from e-Bay. I downloaded the attached program which has been tested and runs perfectly on the simulator. ' ************** TemperatureSensorSerial.bas...

Does the AXE132 pinout align with the pins on this LCD?

This forum has been a great help to me on a previous project http://www.picaxeforum.co.uk/showthread.php?24819-Pinewood-Derby-Stopwatch-Timer&highlight=pinewood+derby and hopefully you guys can help me sort this one out. My Grandson has an idea for a science fair project (heat of fusion of...

I think I know the answer to this but I would appreciate confirmation. I plan on programming the chip off-line to free up space on the PCB. Should Pin 2 (ser in) be grounded?

Every time I try to run this I get the following: "syntax error on Line 39 at/before position 20" Apparently it is not happy with the "start" label, but I cant figure out why. Any suggestions? '=======================FinishLine.bas====================== '===Version 1.0=== ;This program is...

Assuming the chip will be programmed off line, can the 'serial in' pin be used as general input pin?

This is just a goofy little practice program that I am attempting to learn how to use 'outpins'. When I run it in the simulator (PICAXE editor 6.0.5.9) it steps through all the lines in the program, but it doesn't give me an indication on the graphic which pins are going high and low. It works...

First a word of introduction because I am new to this forum. I am a 72 year old retired mechanical engineer. During the spring, summer and fall my passions are fishing and giant scale radio control airplanes. During the winter I revert back to my interest in electronics. I earned my FCC...
