#75263 - RE: LCD IS TAKING COMMANDS BUT NOT DATA
Responding to: ???'s previous message
Hi padmanabham,
Looking at the symptoms you described I guess there is some hardware problem. Check the RS [ Register Select ] line of your LCD. Probably because of some hardware trouble may be some short or something you are not able to pull this line low. Use an oscilloscope to check this.
I use (Y)JHD 162A LCD some 2 years back. I used it in 4 bit mode as well. here is the link to the code that I used.
