That's OK, I thought there was a specific reason you wanted them separated. Here is a drawing of the finish line configuration that I made. Go back to the link in post #10 for the schematic and specifics. The downside of separating the two devices is that alignment is very critical. The...

Here is the interconnect wiring diagram for Tim's project

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...

Yes, that is quite true and I had considered that but decided to go the peripheral route instead. First it allows me to use an 08M2 as the keypad’s peripheral processor because all I need is a single ADC pin. But more importantly, it frees the master processor from needing to...

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...

I was helping the O.P. with this project and was disappointed to see him give up after all the hard work he put into it. Perhaps he will look in on this forum and be re-energized based on what I am about to put forward. I really feel bad because we went away on holidays just as his project was...

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...

What I got was a steady 4 volts dc with some superimposed noise (which looked like the waveform I desired) Traced the problem to a short on the AXE132 which somehow cleared itself just by my handling it. I re-assembled everything, re-loaded the temperature measurement program and everything...

I applied pressure between the screen and PCB, felt a slight click, and the screen is now functioning normally. Thanks for the tip! I checked the continuity between the input pin on the AXE132 and C.6 (pin 15) - no open circuit. Could there be a problem with the programming on the AXE132 so...

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?

I'm pretty sure I already know the answer, but shouldn't all the unused pins be tied to ground?
