I have my x/y joystick control working with 8 Bit inputs for tank style control(i don't want to go through that algorithm again), but I want to use a temp sensor(LM35DT) with 10 Bit input for better...

Ace, thanks, I've been using a Microchip A/D addendum manual I downloaded years ago and I guess it sort of worked because I never noticed severe problems....

This is strange. I've been using a MicroChip 10bit a/d manual (http://ww1.microchip.com/downloads/en/DeviceDoc/31023a.pdf) which shows a different set-up for ADCON1 than the A/D section of the...

My data sheet for the 16f877 shows the ADCON1 register to be set up as follows:
Bit 7,6 Unimplemented, set as 0
Bit 5 "1"= Right Justified, "0"=Left Justified
Bit 4 ...

Thanks but it was right justified. I've added the code below. Sorry, I've forgotten how to use a code window and can't find the thread instructions.

I'm trying re-learn what I thought I understood 3 yrs ago.
I have a 16F877A with the A/D set-up for 10 Bits. Outputing the found value to an lcd.
For my 0-5v input, I have to do FoundValue=DEC...

aratti,
Thanks. Yes that solved the problem. Interestingly, in adding that fix, I discovered that I have to limit the duty cycle value to 254. 255 equates to 100% which means no pulses which means...

I made a board for a dual h-bridge design based on a breadboard I put together on the bench.
I noticed on the new board that I was getting jittery motors as my analog In from the joystick approached...

I think that RC2 is trying to go high but can't because the coil of the relay is pulling too much current for the output. Might have to use a transistor as a switch.

Thanks for the help guys.
After studying further, when I shut the transmitter off, I realized that some values for duty cycle were correct and would fall through to the HPWM Command. The trouble was...

I have an H-Bridge that can run under joystick control or R/C Transmitter Control.
While running under R/C Transmitter Control, I want the PWM to go to zero if the transmitter is accidentally...

I'm getting a good looking 50% duty cycle signal from the CCP1 pin but I just noticed that the amplitude is only about 120mv. I've changed freq and PR2 values and still get 120mv out. I checked the...

I want to build an Industrial device that needs to measure mass air flow in the same range as typical Automotive MAF Sensors. I have searched for actual data(i.e. Actual Mass Air Flow verses Voltage...

Actually I'm ordering some from rentron.com as well as some PIC 16F877's to go on the Proto64 board.

If I use a Resonator that has built in caps, should I still put external 22pf caps around it or none at all?
Thanks,
John

Anyone have positive experience using Micromega's floating point processor?

This is driving me crazy. I'm displaying an analog voltage on an LCD attached to the PIC as adval.HighByte,adval.LowByte(3 233)
I'm also sending the same values to a VB program using the same...

I wanted to look at modedefs.bas but can't find it. I'm still playing with the Demo PBP that I downloaded. Is that the problem?
Thanks,

Joe,
I'm interested in your board. I'm working toward a small board with 16x2 LCD,
2 or 3 a/d inputs and possibly a PWM out.
Couple of questions:
1. What size is the board
2. How does the LCD...

Darrel,
Thanks, I used 10,13 because that is the sequence I amusing to run a 16x2 LCD and displaying the same data that I wanted to capture in a text file using Hyperterminal. The next thing I want...

I'm using Hyperterminal to receive and display data using:
Hserout ["Value=",DEC adval,10,13] which works fine, I get the A/D value "adval" and I get the linefeed and carriage return using the...

Thanks Man,
It was your item 2. I wasn't setting the correct Osc Speed, in this case 20MHZ. DEFINE OSC 20
jrudd

I just realized that my 16F877 is probably running at 20MHZ.
Is there a set-up in CodeLite to set the PIC Speed or will I need the Full Version?
Thanks,
John

I downloaded PBPDEMO and Codelite and I'm trying to program a 16F877 using my FED Pic Development/Programmer Board.
I can find and load the PBP generated Hex File with the FED software and it...
