MicroVGA Arduino support
MicroVGA-TEXT module supports Arduino since firmware version 0.5. Free
Arduino MicroVGA library is available for download (tested with Arduino version 0017).
The MicroVGA communicates with the Arduino in SPI mode, which means that you can use serial port for other purposes (bootloader,etc).
Arduino hardware connection
Connect MicroVGA-TEXT to you Arduino as follows:
|MicroVGA-TEXT pin||Symbol||Arduino connection
|1|| GND||Arduino GND
|2|| +5V||Arduino 5V
|3|| +3V3 output|| NOT CONNECTED
|4|| CS#||Arduino Digital 8
|5|| SCK||Arduino Digital 13
|6|| RDY#||Arduino Digital 9
|7|| MISO||Arduino Digital 12
|8|| MOSI||Arduino Digital 11
Important notice: You must select SPI communication mode in MicroVGA setup (short-circuit "SEUP pad" with power applied) and turn off and back on power supply.
