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. + +Hardware connection +=================== +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.
