embeddedartists 0:c828045bbe69 81
embeddedartists 0:c828045bbe69 82 - A display must be connected to the LPC4088 Experiment Base Board

embeddedartists 0:c828045bbe69 85 - The touch controller uses the I2C bus so for this test to work
embeddedartists 0:c828045bbe69 86 jumpers JP8 and JP9 on the LPC4088 Experiment Base Board must
embeddedartists 0:c828045bbe69 87 both be in positions 1-2
