Alektric, I removed the LCD from the project and still the problem persists.

Hey guys I really appreciate your help. Alain, that schematic that you posted has made me think. I used my multimeter to test input voltage right at AN0 pin and the voltage is steady at 2.432 with...

Attached my hex file.

Javier.

Hey Alain,

Noticed I can't attach my hex file. It is very long to copy paste here.

Javier.

I tried:

ADCON0 = %00000011

as I am using AN0 pin for input now, no change.

Test results:

1.) Didn't see any change when changed to 8 bits, so I'm back to using 10 bits.

2.) I edited my code so only RA0 is being used for input analog.

3.) When connect ADCIN pin to...

Unfortunatelly, I only have the 4620. I can not find pics locally. I am already looking to order more different pics from the states.

Ok guys,

1.) Changed to 8 bits.

2.) Put caps 1uF on each side of the pic on the Vdd and Vss.

3.) No microwaves, no TVs, no fluorescent lights close to my project. I scanned my desk for any...

Hi guys, arriving late from work. I loaded a little schematic I hope is clear. On my project I have 4 LEDs. On this clean one I will use one. Will try 8 bits. I have used caps .1uF and 10uF connected...

I have made a separate project just to clean it. I am reading voltage from the project or voltage from a ac/dc wall power supply sending 3V. Also I have tried reading a angular rate sensor and last...

I tried using a 5V power supply, but I still get the erratic voltage readings.

From the datasheet, I am using:

ADCON1 = %00001101

which specifyes that I am using the project's voltage internally from VDD and VSS for voltage reference. I also tried using external voltage...

Hey Adam,

Thank you for your help. I am scratching my head over the reference voltage. From all the ADCIN samples I have seen, I haven't seen one that says anything about a reference voltage. Is...

Hello everyone,

I am using a PIC18F4620 to read voltages but I am having aproblem where if I read anything in between 0 or 5 volts, the voltages readings are erratic or oscillate. I have tried...

OK, problem solved. On my MicroCode Studio Plus it was showing the In Circuit Debug (ICD) toolbar. I was pressing ICD compile and program button instead of the normal compile and debug button. Now...

Changed the pauses to 1, but nothing. No change.

Hey guys, tried both suggestions and still not working. My code looks like this:

DEFINE LOADER_USED 1 'Bootloader Used
'@ __CONFIG _CONFIG1H, _OSC_HS_1H
@ __CONFIG _CONFIG1H,...

I could think that it is why led on port a is not turning on, but what about led on port d.

I have to leave to work now but I will defenetaly try your suggestion when I get back tonight.

I really appreciate you guys trying to help. The code that you see on my previous post makes the leds blinks, both porta.0 and portd.0. I do not know about other pics, but on the 18F4620 the port is...

Thank you for the links, but they do not help me. Maybe I didn't explain myself clearly. I only use the simulator to write the code which I burn into the chip which works 100% in my real life...

Hello everyone. I am having a problem with PBP where I am not able to program my PIC18F4620. I know everything is OK with my PIC and the circuit as I can use another program called PIC18 Simulator...
