Hi _kaktus_ I have to agree with colcolo... this schematic is not readable :-(

Any chance you could get readable (higher resolution) version, maybe even original PDF...

I have finally managed to flash my GTM32 Rev B using ST-Link, now I just need correct pinouts to make it run properly!

EDIT: I have had some success with reverse-engineering the pinout...

Code: Select all

#define LCD_PINS_RS                     PA13   // CS chip select /SS chip slave select
    #define LCD_PINS_ENABLE                 PC7  // SID (MOSI)
    #define LCD_PINS_D4                     PD1   // SCK (CLK) clock
    #define LCD_PINS_D5                     PD4
    #define LCD_PINS_D6                     PD5
    #define LCD_PINS_D7                     PD7
See attached picture... looks like some adjustments are still necessary

EDIT: I have figured out proper pins now:

Code: Select all

    #define LCD_PINS_RS                     PA12  // CS chip select /SS chip slave select
    // RW is hardwired to VSS
    #define LCD_PINS_ENABLE                 PC7   // SID (MOSI)
    #define LCD_PINS_D4                     PD1   // SCK (CLK) clock
    #define LCD_PINS_D5                     PD4
    #define LCD_PINS_D6                     PD5
    #define LCD_PINS_D7                     PD7
