Programming PIC Microcontrollers in BASIC - mikroElektronika
external hardware.
BASIC has a library for working with internal EEPROM which makes writing and reading data very
easy. Library function EEPROM_Read reads data from a specified address, while library procedure
EEPROM_Write writes data to the specified address.
Note: Be aware that all interrupts will be disabled during execution of EEPROM_Write routine (GIE
bit of INTCON register will be cleared). Routine will set this bit on exit. Ensure minimum 20ms delay
between successive use of routines EEPROM_Write and EEPROM_Read. Although EEPROM will
write the correct value, EEPROM_Read might return undefined result.
In our following example, we will write a sequence of numbers to successive locations in EEPROM.
Afterwards, we’ll read these and output to PORTB to verify the process.
program EEPROM_test
dim i as byte
dim j as byte
main:
TRISB = 0
for i = 0 to 20
EEPROM_Write(i, i + 6)
next i
Delay_ms(30)
for i = 0 to 20
PORTB = EEPROM_Read(i)
for j = 0 to 200
Delay_us(500)
next j
next i
end.
