Another MCBSTM32E board/software problem

Henk van Winkoop

Hi,

newbie getting a little tired of ARM and this hardware/software thing...

Using uVision4 with the MCBSTM32E board with a STM32F103ZE processor.

Besides the startup problem if I download some other example (RTX_Blinky) from the installation Cd-rom then the onboard color display shows the text as MIRRORED text! As if one is reading from the backside of the display.

Where are the experts? ;-)

B.t.w. I'm using Windows7.

    Hi all,

    problem solved. Here's how:

    As I learnt from the LCD datasheet, the display controller is an ILI9320. Datatsheets for that one are easy to find on the web. So I cross-checked the register values in the GLCD_init() function with the list from the datasheet.

    There is a GS bit ("gate scan [direction]"?) in register 0x60 ("driver output control 2"). It was set to 0 by the init code ("wr_reg(0x60, 0x2700);"). By flipping it to 1 ("wr_reg(0x60, 0xA700);"), the display got flipped as well - along the axis intended, fortunately. :)

    Thanks everyone, this helped!
