booster 0 Posted January 15, 2005 Report Share Posted January 15, 2005 I simulated the boost4bit.c lcd test suite on the 16f84 @20MHz. RESULTS: 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. RESULTS: 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. Booster Quote Link to post Share on other sites
Dave 0 Posted January 15, 2005 Report Share Posted January 15, 2005 Booster, Nice spot. This error is not a function of LCD, but of the simulation of 16F628. Thanks Regards Dave Quote Link to post Share on other sites
