#186835 - of course, you can not use a signal that is not there Responding to: ???'s previous message |
The LCD manufacturers in these cases had elected to tie the RW line to the controller to a permanent "write" level on the module so as to save a conductor in the connection cable
of course, you can not use a signal that is not there, but,since the OP has it working with testing the bit, why change to a delay? Erik |
