SX Microcontroler LCD IO routines

Methods

• Matrix LCD driver
   
• 4-bit 8x2 Hitachi LCD driver
   
• lcd8xmpl.src PDF 8-Bit LCD Interface Interfacing an SX uC to a Hitachi HD44780-Driven LCD display, using an 8-bit parallel data bus without interrupts.

• PIC C Hitachi LCD Drivers by Andy Kunz
   

Integrations:

• lcd.src Comparitive resistance meter with LCD Driver This software uses two software A/D converters, on pins RB.5 and RB.6, to read in a known resistance value, and compare it to an unknown, and then outputs the results on an 8-segment LCD. The RA pins drive the commons, and the RC pins drive the characters

• Bitmap to table converter Opens FNT (Windows Bitmap Font) or BMP (Windows Bitmap Picture) files and writes out a C language data table.
