Thanks for you help.
The 1st site are in french The 2nd site use C for Arduino board. I'm looking for code in ASM to 89s52. I'm study every night from 21hs to 24hs and read all datasheets I'm try de code below Seemed incomplete ? Such a project is best turned into two separate sections : First, prove your i2c code can read/write to the 8574. Then, apply some proven LCD 4 bit mode init code, to that, and confirm you wake up the LCD correctly. Also, you might prefer the AT89LP52, generally faster/smarter than the 89S52. |
