STM CircleOS forum / Inverted display on Primer1 with CircleOS 3.7

Toley · 2009-06-27 19:32:03

I have upgrade to circleOS 3.7 on my Primer1. When I run in Debug mode, the display is inverted. See the above image. Is it normal ? Is there a solution for this issue ? Thank you for any help.

Hej,

Long time ago i gave this solution:

In the LCD.C:

static void LCD_7637_Controller( void )
{
extern void starting_delay ( long unsigned );

/** Apply hardware reset **/
LCD_CtrlLinesWrite( GPIOx_CTRL_LCD, CtrlPin_RST, Bit_SET ); /* RST = 1 */
LCD_CtrlLinesWrite( GPIOx_CTRL_LCD, CtrlPin_RST, Bit_RESET ); /* RST = 0 */
starting_delay( 0x3000 ); // Changed from 0x500

LCD_CtrlLinesWrite( GPIOx_CTRL_LCD, CtrlPin_RST, Bit_SET ); /* RST = 1 */
starting_delay( 0x3000 ); // Changed from 0x500

Then it can run witout the delay in main:
/* The LCD monitor is not always properly initialized:
the starting delay allows to wait for a longer power up. */
#ifdef PRIMER2
delayms(100);
#else
starting_delay( 100 ); // KJ - Changed from 0x10000
#endif

But it seems not to be integrated into the circle os, you can change it an compile the circle os, and give feedback here if it works
