Has anyone ever used a lumex four line display? I am trying to connect the 18f14k50 to it in 4-bit bus mode and all i get on the output is the second and the fourth lines completly dark and nothing...

I recently wrote code for the 18F14K50 chip and it seemes that i cannot get the code to run at all. When i power up the board the LCD stays blank. I added the debug value write to eeprom just to see...

I am using this code on the machine itself right now. The load for all the outputs of the PIC are N-channel mosfets that turn on 12 solenoid valve coils. I have flyback diodes on all the coils to...

I have made the program below to run a simple leak test fixture. The problem I am having is that the machine randomly gets lost and the two bottom seal variables lock in the 0 or off position and do...

i have written this test program to become more familiar with the timer0 module. The only problem is that according to my calulations from the calculator that was posted on this thread the timer...

I have found this little bit of code from the forum and am trying to do something similar to this with the TMR0 module on a 12F675. I was just wondering how tey came up with the 16.384ms for the time...

I have written the piece of code below and it works at the endpoints of 0.25 to 25 sec for the on time and 30 to 60 sec cycle time. The problem is that it does not work for numbers in between. I...

I had figured out how to do the other post by using the code below...

ON_TIME:
PAUSE 525 ' low end pause time

i AM TRYING TO CREATE A TIMER USING A 12f675 and am having trouble doing so.

The timer works by using two pots to control the ON time and the CYCLE time.

In other words i use one pot to set my...

no this is not the entire programs i have my defines set as follows

I am relativley new to programming and am trying to make a simple timing circuit with a PIC12F675. I have written some code that uses a potentiometer and the AD converter to scroll through the time...

I was wondering if anyone could maybe explain to me how the micro determines a specific time with different oscillator speeds. Right now I can determine that if im using a 4Mhz internal oscillator...

Melanie,
I have tried to emulate your schematic and have found that without the 5V Regulator the ciruit provides 11.7 V, but as soon as I add the regulator or put any kind of load across the circuit...

Melanie i was wondering if you could suggest a manufacturer of the VDR used in your design.
