Incorrect Touchscreen Mapping Code in Example Files #43

Was using the Adafruit TFT FeatherWing 3.5" 480x320 Touchscreen (Version 1) with an Adafruit HUZZAH32 ESP32 Feather Board and found a mapping error in two example files.

For: examples/touchpaint_featherwing/touchpaint_featherwing.ino Line 156 p.x = map(p.x, min_x, max_x, 0, tft.width()); should be p.x = map(p.x, min_x, max_x, tft.width(), 0);

For: examples/gfxbuttontest_featherwing/gfxbuttontest_featherwing.ino Line 266 int py = map(p.x, max_x, min_x, 0, tft.height()); should be int py = map(p.x, min_x, max_x, 0, tft.height());

For both example files, the correct file for the Version 1 screen had been selected: // If using the rev 1 with STMPE resistive touch screen controller uncomment this line: #include <Adafruit_STMPE610.h> // If using the rev 2 with TSC2007, uncomment this line: //#include <Adafruit_TSC2007.h>
