Hi,

Has anyone ever written a display driver for this GLCD controller in parallel or 3-wire SPI mode? (16 wire interface)

pinout includes:
---------------
1 Vout
2 Vss
3 D0
4 D1

skimask,

not sure yet, I want to take the voltage measurments and see how they look with respect to orientation.

Basic question, if I give the micro a ref voltage, should it not scale the...

Hi,

Thanks and I finally get it. It did work on the 16f877a but I have to remember, each PIC device has its own little kingdom of parameter and register. I mistakenly figured this was a common,...

Hi,

ver 2.46, MPASM 5.1

I think it is an problem with the 18F4431. I can compile code for the 16F877a with both MPASM and the default compiler and it works just fine. I have tried to compile...

Hi,

Ver 2.46, MPMASM 5.1

I have the processor above with an analog accelerometer. The values I'm getting from the conversion are incorrect with respect to the reference voltage supplied. I...

As the title suggest, I started to get a compile error with this line of code.

Any suggestions? It did work a day or so ago.

thanks

Thanks for the links and info.

Okay, I read the threads suggested and I'm more confused than before but I believe I have the bits set. I checked by importing the *.asm file into MPLab ver 7.52...

Verified, using MPASM 5.1.

If I want to config the PIC to run at 8mHz, I thought it was simply this:

DEFINE OSC 8

Is this incorrect?

Hi,

Using MPMASM, not sure how to use the 'default assembler'. I just found the PIC18EXT.bas file and defs. I can set the clock and other SFR values and test.

BTW, do all suppor the...

Okay, I added:

DEFINE OSC 8 and added a PAUSE 10 (see below) in the loop: and another message so I toggle between the two.

The message still takes ~ 2 sec to toggle. Another thing I've noticed...

Hi,

I have a 44-pin demo board with a 18f4431 driving a Varitronix LCD display. After I push the program to the pic with a PicKit2.

The problem is it takes 30-40 sec for the display to show...

Bob,

Thanks for the reply and link but the link is 404 and I'm not sure who Bruce is. Can you spare some more details. Yes, yes, I'm new.

thx

Thanks for the reply, I only included the code I figured might be giving me the problem. My Bad!

After re-reading the correct DS, I figued out that RA4 cannot be configured as an Analog Input. ...

Hi,

I get these warnings when I compile for an 18F4431 using MASM:

Warning[230] c:\pbp\18f4431: __CONFIG has been depreciated for the PIC18 devices. Use the directive CONFIG.

I tried this...

Hi,

Using the X1-demo board and a 877A chip. All I want to do is config portA so I can use the pins, An2, An4 An5 to read the voltage from and accelerometer. I started with the A2D8.bas demo...

Try www.globalsources.com, lots of manufactures with lots of sizes.

Hi,

Okay, I'm new to the fw thing and have a few questions about storing, incrementing and displaying large numer.

I have a project where a user will enter a trigger-value between...
