#161299 - You need to obey the data sheet. Responding to: ???'s previous message |
I have done some guesswork about your variable names.
1. you need to have correct timing around your strobe pulse. 2. in general your Enable should only be high during the enable pulse. You read the port after the setup time and DURING the enable pulse. Then take enable low, so that the chip is always in three-state. 3. read the data sheet to see that you do a "double" read for data. 4. there are MANY working ks0108 drivers that are publicly available.
