pic wattmeter
I am planning to have this project implemented. But I had not much knowledge on circuits.
Bigger picture here
Well, 1st of all is the part on the input at RA0 served as the voltage sensor. I am not very sure on why there is a potentiometer located parallely with the 4k7...
LCD to serial
Hi everyone. I had implemented a project on watt meter. Currently I am using 4 data buses to display characters on the LCD. But at the same time I also need a serial data out of the PIC. Which method is preferable? Using serial routine in assembly coding or parallel in serial out...

Watt Meter
Project reference: **broken link removed**
ASM code: **broken link removed**
Schematic: **broken link removed**
My Watt meter:
I am using the schematic as shown above, however there is minor change where I didn’t use any switches (S1, S2, and S3) and the...
UART problem....
Hi, I am now using PIC16F88 which has hardware UART for my project. Previously the asm code is written such that to display the reading to a 16x2 LCD. But now i need to have these data input to another RF module. The RF module has 2 pins for UART data IN and OUT. Beside, it...
Ground, reference point
Well basically how can I get a ground connection on a circuit board?
A circuit board will have 2 rails, one at the upper connected to the positive terminal of the source (battery) and the other will be the negative terminal from a battery. How about ground? Because my...
ASM programming
Hi to all ASM masters. Basically i am doing a project on wattmeter using PIC, LCD and other components like CMOS voltage converter, 3.3V regulator etc. But when it comes to ASM, i headache.
To be honest I am getting the asm source code from the web (here), and the latest is...
pic16f88 programming
Well, if possible, mind to share which part should be take note or configure?
Because I always see no device detected message.:cry:
pic16f88
Well basically I have a burner with Microchip PICkit 2 software. However I figure out that it does not support PIC16F88. How am I manage to burn my HEX file? Thanks for the guidance.
pic 7 segment display
Hi everyone, I am doing a project, and I'm now facing a critical part. As we know 7 segment display has 10 pins, while 7 pins are used for displaying a character. In my project, I am using 3 characters for a particular reading, for example: 123, which means 21 pins...
lcd graphics display chip on ribbon cable
Well thanks for the reply...
I think this is more like Alphanumeric display.
I just want to get the reading out and input into PIC
configure kill a watt
Thanks for the replies!!!
But what is meant by these pins anyway?
D4-D7
E 1
RS 1
Sorry I just found it a bit complicated. Thanks again.
kill a watt serial interface
Hi all the experts here:
Basically I was having my project. But then I need the data from a device called Kill A Watt. Before it has been drived to the output, there are 6 connections to the LCD driver as shown below:
The LCD seems to have 20 pins configuration...
