Problem Testing arduino sketch in actual uno board (by Ahmad sakr)
I made a simple program to test persistent instruction and I compiled the sketch for arduino and I added liquid crystal codes in the arduino Zz.cpp file at lines (18,19,183,184,185 and 186)
I simulated the arduino hex file in protus and everything is good but when testing in actual arduino uno 328 board, there is no response even pressing up and down keys the x value still 0
I connected the wiring like in protus in the attachment
What is the cause of not working in actual?
I'm using ldmicro 439 and arduino ide 185
Thanks for the good support

1) To manualy fix writing to EEPROM
replace
Write1_Ib_scratch(); // EEPROM is ready
to
Write0_Ib_scratch(); // EEPROM is ready
https://github.com/LDmicro/LDmicro/issues/82
Will be fixed in 4.3.9.2
2) Check the nominals of the resistors.
