can you please help me to read write custom character array to EEPROM?
viewtopic.php?f=88&t=80542&p=318319#p318319

How to read and write custom character array to EEPROM? Please guide. // [b]want to write/ read const char STR,RC,NC,NU,SQR,RU to EEPROM[/b] const char STR[] = {3,3,3,3,3,3,3,3}; const char RC[] = {31,31,3,3,3,3,31,31}; const char NC[] = {31,31,24,24,24,24,31,31}; const char NU[] = {27,27,27,27,27,2...

I have split a 32 bit long integer to 8 bits and saved to 4 locations on the EEPROM. The For loop code doesn't work, there seems to be problem with "Distance |=" but I do not know how to solve it. Please guide // PIC16F886 void read_saved_odo(){ unsigned long int Distance = 12345678; unsigned int i;...

Ah... I think I can maybe guess what you wanted....

You want to show time past 100%?

Makes no sense to me - this is just a confusing indication in my mind, but here it is anyway...

I have checked the code in Proteus simulation, will program the pic and check it in actual hardware.

Updated code version attached See comments at top of code to see what has changed Your previous code works perfectly. I have done some changes in it to suite me. Your code if(batt_cap = 0xffff){ // is EEPROM blank? batt_cap = 18000; // if so, then default to 18 AH } I want it to be universal upto 6...

Attached is my attempt at a quick fix // status 29 June 2023 // // Only changes from original are : // 1 default to 18 AH if EEPROM is blank (as when programmed) // 2 formatting improvements // 3 timing display over-ridden with a new simpler function // // - will latewr provide a function for text ...

If you want a complete answer, post your full code
I promise that nobody will want to steal this code

Here is my full code viewtopic.php?f=88&t=80057

Double post

I have modified code available in the internet to create a battery coulometer using PIC16F886 and 20x4 LCD display. All function works well, except Time remaining. All other readouts change instantly only time remaining literally works like a counter. eg. If I draw 18 amps from a 18aH battery the ba...

Found the answer

How to enable weak pull up resistor on all pins of PORTB except RB1 on PIC16F886

If you want a complete answer, post your full code I promise that nobody will want to steal this code :wink: I have no issues in posting the full code as I have copied the code from the internet for a voltmeter using PIC16F877A and have modified it to make a battery coulometer. Infact someone could...

There are a lot of errors in your code - too many to list Here is my attempt at fixes, but mostly guesswork from the limited snippet of code given // simple program for forum - a complete mess, but do not blame me - I did not write it // PIC16F877A with 8 MHz external 2-pin crystal // EasyPIC V7 bo...

I am trying to call functions using the switch case method but i am getting a compiling error "Undeclared identifier (Function_name) in expression". How do i solve the error? void main_menu() { unsigned int ex = 1; unsigned int sw = 1; CustomChar(1,1); Lcd_out(1,3,"Battery Capacity"); Lcd_out(2,3,"C...

Use this code for LCD Data, IRP problem will gone... void Lcd_COut(char row, char col, const char *cptr) { char chr = 0; //first, it is used as empty string Lcd_Out(row, col, &chr); //nothing to write but set position. for ( ; chr = *cptr ; ++cptr ) Lcd_Chr_CP(chr); //out in loop } write in code......
