I'm using TSC2046 from TI, but I don't like it. The MCU must read a lot of samples (X and Y) to filter noise and false values. A lot of job and bus activity. It is command based.
TSC2006 could be a good alternative. It is "register-based", so it avoids a lot of job in MCU, after an initial configuration.
Do you know and suggest other good touch screen controllers, maybe from other manufacturers?
