Hardware This product has been designed to simplify the implementation of TFT technology into your product yet provide a high level functionality. The high level text based object oriented command structure, entity library and multi page screen memory allow most of the processing to be undertaken by the TFT module leaving the host CPU to concentrate on the core application processes. This allows proven firmware running on small 8 bit microcontrollers to be modified to drive this TFT with a minimum of work and risk. *option Connector Pin Assignment Connector 1 - RS232 / RS485 / RS422 Back Front Pin/Cn1 RS232 RS232/485 RS232/422 1   2 2   1   1 NC RT+ T+ 2 DTR - R- 3   4 4   3 3 TXD TXD TXD 4 CTS CTS CTS 5   6 6   5 5 RXD RXD RXD 6 RTS RTS RTS 7   8 8   7 7 DSR - R+ 8 NC RT- T- 9   10 10   9 9 GND GND GND 10 5V 5V 5V Connector 2 - Supply / Piezo   Pin/Cn2 Supply/Piezo           1 5V 2 /Pz 3 2 1 3 0V Connector 3 - I2C / Async / SPI / IO ports Back Front Pin/Cn3 I2C Async SPI IO ports     A + B VBB = 5V VBB = 5V VBB = 5V VBB = 5V B + C VBB = 3V3 VBB = 3V3 VBB = 3V3 VBB = 3V3 1   2 2   1 1 VBB VBB VBB VBB 2 SCL - SCK K24 3   4 4   3 3 - SI /SS K25 4 SDA - MOSI K26 5   6 6   5 5 0V 0V 0V 0V 6 /IRQ - MISO K27 7   8 8   7 7 - SO /IRQ K28 8 /RES /RES /RES /RES 9   10 10   9 9 - MB MB K29 10 - HB HB K30 Jumper ABC are solder pads.
