Mackrackit,

You were right again sir... I missed that part lower down. I discovered that what I was trying to do would not work because it would require 12 locations rather than 8. So I changed...

Thank you for your response... I've looked at the two links that you posted and I understand now how to write the data to the CGRAM registers. How though, do I tell the LCD a specific location to...

All,

I am trying to find a way to create custom characters using the CGRAM of a 20x4 LCD. I've been trying to browse online and I've only located ASM examples. I can't completely understand ASM...

Lol it is quite a possibility. Most of the time I'm working on this stuff I have my two small kids playing nearby... so it's quite easy to get distracted.

Sorry it has taken me so long to get back to you. I've been busy with work and haven't had much of an opportunity to work on projects at home. Now that I've found the time, I have tried programming...

I wasn't sure where to post this so I thought I would post it here... I seem to be having an issue with my PICs receiving my programs throught the melabs programmer... I write all my code using PBP...

Hello all. I will be using a PIC16F877A for the project that I am currently working on. I have used this chip in the past, however, I've never programmed it in assembly language before. Right now...

Yes I tested it... I successfully sent a message through my cable and echoed it back by shorting pin 2 to pin 3.... any other ideas?

Added:

Is there anyway to tell if my cable is crossed as you...

I am attaching a bitmap of my schematic for my ICD and ICP. I am using the ICD for the serial communication.

I tested my serial port and sent 5 succesfully in the loopback... what else can i try?

Well... you'd have to give me a while to get a schematic drawn up. There are 4 caps on the 232. The cable is a regular serial cable, male on one end female on the other. I don't have a USB to...

I copy and pasted the code you provided me but had no luck with it...

I have scratched the line as you suggested... however, it still isn't working. If I try to transmit the example in my code, which is A369621... I don't receive anything back at all. Also, if I...

Yes I have a MAX232 on the ICD I've built... it should also work as my serial communicator for this purpose as well... This is the number on the chip:

69CT01M
MAX232IN

TTL to CMOS...

Hello again to all... I am testing pieces of code that I have put together from various sources. I am trying to get a communications link set up between my PIC16F877A and my PC. I am using the...

you know... looking at that, i always try to make things complicated... lol. from what you've posted here i realize that whatever the value of the adc is it will multiply it by the 10mA and give me...

I am using the PIC16F877A to measure current flowing through a shunt. The way that it works is basically this: with every 10mA increase in current, the adc should increase by 1. I need help with a...

that's what i'm thinking but i'm not entirely certain... i've tried a couple of different things but to no avail so far...

I have attached a schematic of what my circuit looks like. However, I have switched the 100 ohm resistors with 10k resistors and swapped the positions of the resistors with the photocells.
...

A friend and I have been working on a robot for a while now. It started as a senior design project in college. As our knowledge of the PIC grew, we made certain improvements to the project such as...

ok i was thinking that bit 0 and bit 1 would just be moved to where bits 2 and bits 3 are... thus showing bits 0 and 1 twice and losing bits 8 and 9 with the code you provided me with... i'll give it...

Doesn't this line just shift everything two bits to the right:


portb = (light >>2)


By doing this I'm actually losing two bits right?

Hell again all... seems like I get one thing fixed and something else goes wrong. I am having a problem with my ADC on the PIC16F877A. Here is the code that I am using:



DEFINE OSC 20
DEFINE...

I need help. I've tried using the timers before and I just don't seem to be doing something quite right. My goal is this. I have developed an intelligent mobile robot using the PIC16F877A. It...

Thank you for that. Many people have told me that I should use assembly language because it is much faster. But working with PBP, as I have always done, seems to work just fine. The only problems...
