Rev.1.2 ORDERING INFORMATION VERSION DESCRIPTION Revelation Board vA Revelation Board dedicated for 2.83”, 3.5” and 4.3” Riverdi TFT module Revelation Board vB Revelation Board dedicated for 5.0” and 7.0” Riverdi TFT module QUICK START Our Revelation Boards are preprogramed in factory, so to evaluate Riverdi TFT modules with FT8XX controllers, just follow these steps: 1. Connect TFT module via 20 pin 0.5mm FFC to CN8. 2. Connect micro USB 5V power supply to CN7. 3.
Rev.1.2 2.1 TFT connection to MCU TFT module is connected to MCU using SPI interface (it is also possible to set I2C as a main interface, by changing SB1 – SB4 shorts). Figure 2 shows TFT connection diagram. For more information see Riverdi B-series TFT panels datasheet and STM32F031C6 datasheet. Figure 2. Connection TFT panel to MCU 2.2 Board programming The Revelation Board is based on STM32F0 family MCU. Board can be programmed using STMicroelectronics ST-Link.
Rev.1.2 Figure 3. Backlight power selection z Board also allows to measure two current values. The LCD current measure (FT8XX current + LCD TFT current + Touch Panel (if mounted)) is available on CN3. The backlight current measure is available on CN6. Before measure LCD current you should unsolder SB5, and before measure backlight current you should unsolder SB6, see Figure 4. Figure 4. Current measure method 2.4 User application Revelation Board allows to build user own application on board.
Rev.1.2 Figure 5. S1 and D1 connection diagram U1 is a 8 Mb flash memory. Connected to MCU via SPI interface. Flash memory is not required to use Riverdi FT8XX displays. It is an additional element which can be used in user application. For example to storage graphics elements.
