#185193 - Hardware or software Responding to: ???'s previous message |
It works great with 4 analog / digital pins of microcontroller. Actually it was perfect first time. However looking at the way Arm development board did it they used a dedicated resistive touch screen controller chip ADS7843.
Generally is it better to choose a dedicated chip for this type of job or do it easy way using 4 analog / digital pins of a microcontroller and software? However looking at the price of ADS7843 chip price was 8 pounds qty 1, looking at the price of 3.2" color tft lcd with touchscreen and a chip was 13 pounds. Mahmood |
