eeprom for pic16f877 - Electronic Circuits Projects Diagrams Free

eyr · 25th October 2009, 09:58 AM

i am having trouble programming pic16f877a. i have a code using MicroC that includes use of eeprom to display words in a dot matrix. I can simulate it in Proteus but when it comes to actual it doesn't work. I am using WinPic as the programmer.can someone help me please if winpic involves other settings to enable the eeprom of pic16f877a???

Hi,

First you need to see if your code is being loaded in to WinPic correctly.

If you load your program then open the Data folder you should see your eeprom code.

If the data is there then check the Options folder that the Data box is checked on to program it.

You should first check that your pic is actually programmed and running.

Does your programmer verify the code?
Have you tied MCLR to 5V?
Does your crystal have the correct capacitors?
Did you select the correct oscillator in the config?
Do you have a clean power supply?
Correct decoupling capacitors?
etc.

Mike.
