Plz suggest the right programme of the EEPROM

[bikash123]

hello friends, plz tell me how i will display in lcd using interna eeprom of pic16f877a microcontrollers.plz hel me . my compiler is micro c. i have written to this programme . what will require t0 write plz tell me. urgent one.diagram also tell me. plz...

I have written this program in micro c and also build it after then i am using this program in microcontroller but what happen, it does n't displayed in LCD. So, where is the problem i am unable solve it. Plz if any bodyhave suggestion plz share it. so that i can solve to that problem.

 

[internetuser2k11]

Post your full code and circuit diagram.

 

[bikash123]

this process i have drawn diagram, plz suggest how to solve it.

 

[tpetar]

What code did you try ?

 

[bikash123]

i want to store the battery charging stage at every 10 sec intervals. the battery is 12V and 7Ahr capacity. It is connected with a solar module of capacity 10Wp and 0.4-06 short circuit current with 12v supply.
Charge= current*time concept. when the battery voltage will reach 7Ahr then it will disconnect the supply.

Where is the code?

this is my code sir, i am using this....not success

 

[internetuser2k11]

Use adc to read the battery voltage. If voltage = 12V then stop charging. Why are you doing eeprom thing? post your circuit.

 

[tpetar]

Put code in wrap tags or Alex will....

 

[internetuser2k11]

I didn't put that code.
