This is a demo project for testing the TDISP/HD44780
on a STM32F4-Discovery board.
The first line of the display will show: ChibiOS/GFX
The second line wil show: TDISP/HD44780 with a custom charactor in front.
If the connected display is a 4 line display:
The third line will stay empty
The forth line will show the cursor modes.
The demo is written for a 4 lines display. If have a display with less lines, change the TDISP_COLUMNS setting
gfxconf.h in the project directory to the count of your display.
The software will react upon this setting.
The datalines D4 to D7 of the HD44780 compatible display must be connected to the PE0 to PE3 output pins
of the Discovery board. The RS-line of the display must be connected to PD0 of the Discovery board
and the CS-line of the display must be connected to PD1 of the Discovery board.
The R/W-line of the display must be connected to ground, because reading from the display is not used.
The project directory contains a custom STM32F4 Discovery board file. If you want to change the connection to
the Discovery board, change the custom board file accordingly.
You have to check the provided Makefile to meet your installation of the ARM-GCC Toolchain.
