Ok, if you own one of these testers, marked Electronics Studio on the back and would like to install the M firmware, you have to make the following adjustments in the ST7565 section in the config_328.h file, copy attached:
/*
* ST7565R, SPI interface (bit-bang)
* - settings for Electronic Assembly EA DOGM/DOGL128-6
* - uses LCD_CS to support rotary encoder in parallel at PD2/3
*/
#define LCD_ST7565R
#define LCD_GRAPHIC /* monochrome graphic display */
#define LCD_SPI /* SPI interface */
#define LCD_PORT PORTD /* port data register */
#define LCD_DDR DDRD /* port data direction register */
#define LCD_RESET PD0 /* port pin used for /RES (optional) */
#define LCD_A0 PD1 /* port pin used for A0 */
#define LCD_SCL PD2 /* port pin used for SCL */
#define LCD_SI PD3 /* port pin used for SI (LCD's data input) */
#define LCD_CS PD5 /* port pin used for /CS1 (optional) */
#define LCD_DOTS_X 128 /* number of horizontal dots */
#define LCD_DOTS_Y 64 /* number of vertical dots */
#define LCD_START_Y 0 /* start line (0-63) */
#define LCD_CONTRAST 11 /* default contrast (0-63) */
#define FONT_8X8_VF /* 8x8 font, vertically aligned & flipped */
#define SYMBOLS_24X24_VFP /* 24x24 symbols, vertically aligned & flipped */
#define SPI_BITBANG /* bit-bang SPI */
#define SPI_PORT LCD_PORT /* SPI port data register */
#define SPI_DDR LCD_DDR /* SPI port data direction register */
#define SPI_SCK LCD_SCL /* port pin used for SCK */
#define SPI_MOSI LCD_SI /* port pin used for MOSI */
I am also enclosing version 1.31M compiled versions of the .eep and .hex files in version1_31.zip file for your convenience.
