Back to 4x Serial to Ethernet Terminal Evaluation Kit Ordering Page The TEV-LB2 board carries a 176x220 AMPIRE AM176220 TFT panel. This panel is based on a HIMAX HX8309 controller. There is also a control line for panel's backlight. The image displayed on the panel is not visible unless the backlight is turned on. Related datasheets, as well as the schematic diagram for the TEV-LB2 board can be found on Tibbo website.

(2) Backlight control line. Required initialization code in Tibbo BASIC applicationThis section assumes that you are familiar with Tibbo BASIC and TIDE software. These are documented in the Tibbo BASIC Programming Guide. For correct panel operation, click Project-> Settings, and select EM1000 or EM1000W platform. Additionally, click Customize to open a Customize Platform dialog. In the dialog, double-click the Display Panel Type line and choose Himax HX8309 (Ampire AM176220). The following initialization code should also be added to your project: lcd.iomapping= 44,43,42,41,40,4 RST,DC,WR,RD,CS,data_bus io.num=PL_IO_NUM_44 io.enabled=YES io.num=PL_IO_NUM_43 io.enabled=YES io.num=PL_IO_NUM_42 io.enabled=YES io.num=PL_IO_NUM_41 io.enabled=YES io.num=PL_IO_NUM_40 io.enabled=YES lcd.width=176 lcd.height=220 lcd.rotated=NO lcd.inverted=NO lcd.enabled=YES
Use the following code to turn on the backlight: io.num=PL_IO_NUM_47 io.enabled=YES io.state=LOW Back to 4x Serial to Ethernet Terminal Evaluation Kit Ordering Page
