I have a problem in my program.
This program is to write in eeprom(hn58x2432) & read from it to
display
to lcd module.It is transmit by I2C.
Please help me to check my program.
Thanks.
It have some problem when it compiled.Below is the error message.
LINE 11 ACK REG P2.0==============>ILLEGAL MNEMONIC
LINE 12 SCL REG P2.1==============>ILLEGAL MNEMONIC
LINE 13 SDA REG P2.2==============>ILLEGAL MNEMONIC
LINE 14 COUNTD EQU 41H ==============>ILLEGAL MNEMONIC
....
Just like that
===============================================================
I don't know some else bugs in it,so help me check it,please.
Thanks.
