Lcd Plugin & 16f628

Recommended Posts


I simulated the boost4bit.c lcd test suite on the 16f84 @20MHz.


Simulatuion: ok

Real-Time : ok

I modified the header file to accept 4MHZ based timing delays to run on the 16F628 (using internal 4MHZ clock - no clockout).

I reconfigured high nibble data port as PORTA.



Simulation: ok

Real-Time : gave garbage on lcd but garbage 'on time' appeared to be consistent with expected correct display 'on time'.

After looking at the spec I found that RA5 can ONLY be configured as digital input, NOT as I/O. The LCD plugin lets the configuration pass as output.
