Драйвер для LCD TIC107(PCF2119x).  Попробовал использовать индикатор Tic107. Написал к нему драйвер. Может быть будет полезен еще кому. Буду рад получить Ваши отзывы и замечания. Драйвер: //================================================================================================= /* Driver for the LCD TIC107(PCF2119x). Interface i2c. Compiler CCS.
