I'm long-term embedded, but new to PSoC's.
PSoC Creator 4.2 appears to offer two relevant Component options for multi-line LCD displays:
a) Parallel connection to an LCD equipped with an HD44780 controller
b) I2C bus with an LCD equipped with a PCF2119x controller
We need to be frugal with GPIO, so we can't dedicate an entire port to an LCD.
The market is heavily saturated with 4x20 I2C/HD44780 LCD panels, while a 4x20 LCD with I2C/PCF2119x controller seems rare. I'm using PSoC4 CY8CKIT-049 trying to incorporate PSoC4 / 4200M in my projects, so any guidance in this regard would be sincerely appreciated.
