embeddedartists 0:79b286950b60 81
embeddedartists 0:79b286950b60 82 - A display must be connected to the LPC4088 Experiment Base Board
embeddedartists 0:79b286950b60 83 with the FPC connector
embeddedartists 0:79b286950b60 84
embeddedartists 0:79b286950b60 85 - The touch controller uses the I2C bus so for this test to work
embeddedartists 0:79b286950b60 86 jumpers JP8 and JP9 on the LPC4088 Experiment Base Board must
embeddedartists 0:79b286950b60 87 both be in positions 1-2
