I'm a student. My name's Tam. i want to design circuits with led matrix, AT89XX, CPLD, EEPROM and PC.
When i type text on PC (using Visual Basic with text box), data will load to AT89xx, then data will fix to EEPROM. Then, I turn off my PC. Data will be into EEPROM. I use CPLD to shift and to control column of matrix led (about 100 column).This mean is "I want to use CPLD to access data into EEPROM", which are loaded from my PC throught VisualBasic. But i don't know begining anywhere.
Can you help me?
Thank you very much.
