I am using the Adafruit MPR121 12-Key Capacitive Touch Sensor Breakout Board. It is working well with an Arduino Uno R3. I am attempting to use this Breakout Board with a TI microcontroller, MSP430G2553. I have established I2C communications with the Breakout Board. However, I have not ...
On an UNO & '328 based Arduino, this is also A5, on a Mega it is also known as digital 21 and on a Leonardo/Micro, digital 3 Connect the SDA pin to the I2C data SDA pin on your Arduino. On an UNO & '328 based Arduino, this is also A4, on a Mega it is also known as ...
boards to my Arduino Uno at addresses 0x5C and 0x5A. The boards are recognizedcorrectly. However, I would like to how I can set both boards in AUTOCONFIG mode and how I can adjust the TOUCH and RELEASE thresholds for each sensor on both boards. At the moment I u...
