![]() The common anode for the four LEDs is tied to the 3.3V supply. Underside of the NB3000-TFT01 satellite board, showing theģ7-pin LCD Flex cable (left) and the 1.8" ATA/IDE interface (right).Ĭontrol of the backlighting – the four LEDs – is acheived using a single signal from within a design programmed inside the User FPGA, TFT_BLIGHT. All display-based signals from I/O pins of the User FPGA (originating from an in-design ILI9320 LCD driver peripheral) are routed through to this header, in addition to interface signals for the backlight and touchscreen, and required power supplies. The panel connects to the satellite board on which it resides, through a 37-pin LCD Flex connector. Used to attach the satellite board on which the TFT Connection is made using a 40-way flat-flex cable.ġ.8" ATA/IDE interface connector on the motherboard, This satellite board connects to the motherboard using a standard 1.8" ATA/IDE interface, courtesy of a 2x20 FFC header located on each board. The panel itself is mounted onto a small satellite PCB (NB3000-TFT01) which is then fitted into a custom injection-moulded plastic part, which lifts the display off the motherboard, in turn creating a better viewing angle. Power for the panel (system, digital and logic supplies) comes from the motherboard's 3.3V supply. This results in Data Bus lines TFT_DB8 and TFT_DB9 not being used, and a total of 65536 colors being available for display. Although capable of supporting 262144 colors (RGB, 6-bits parallel), the panel is fixed to use 16bpp display on the NanoBoard, by tying the Interface Mode pins ( IM0 and IM3) to GND. The display has a CPU/register-oriented asynchronous Intel i80 bus interface, handled through an ILI9320 driver chip (from ILITEK). The display is based on an active matrix and backlight for the panel is provided through four white LEDs – wired in parallel, with a commoned anode. The 2.4" panel features a Transmissive Color TFT LCD, with a resolution of 240(W) by 320(H). The panel also features an analog resistive touch screen.įrom a user perspective, you can either output straightforward graphics to the panel, or provide a more sophisticated level of interaction involving input to your FPGA design from the touch screen. The NanoBoard 3000 provides high quality color display through a TS8003K TFT (Thin Film Transistor) LCD panel (from Shenzhen Techstar Electronics). ![]()
