Porting ComponentTester-1.47m firmware to LCR-T5 required changing contrast resistor ratio from 6.5 to 4.5 in ST7565R.c

[ejouellette]

Hi,

I was able to configure ComponentTester-1.47m firmware to work properly on a LCR-T5 meter, based on the STRIP_GRID_BOARD = 5 LCD port mapping found in Karl-Heinz firmware. In order for the LCD contrast to work properly within the LCD_CONTRAST range of 1-63, a minor edit to ST7565R.c was required:

The lines:
/* set contrast: resistor ratio 6.5 */
LCD_Cmd(CMD_V0_RATIO | FLAG_RATIO_65);

should be changed to:
/* set contrast: resistor ratio 4.5 */
LCD_Cmd(CMD_V0_RATIO | FLAG_RATIO_45);

I've also included the other modified config files: Makefile, config.h, and config_328.h.

Hope this helps!
