Peripherals
Displays
Different screens and displays can be connected via serial interface. Connection of character screens in parallel mode is also supported.
Serial TFT
Many displays are supported by the driver https://github.com/notro/fbtft , which is not yet integrated into the mainline kernel. List of supported driver models: https://github.com/notro/fbtft/wiki/LCD-Modules
Below is a list of screens tested with Wiren Board.
- 2.2’ TFT LCD: TFT01-2.2 SP from Elecfreacs and clones, 320x240 color, chip ILI9341,starting from $6.5 at retail
Zigbee MiWi transciever
Interfaces
RS-232
- MOD-RS232 - TX/RX only. Connect up to two modules to the Board. The connection uses UEXT1 ( Debug UART must be disabled) and UEXT2 (cannot be used simultaneously with RS-485)
- Adapters USB-RS-232. Up to two cables without using an external USB hub. Possible programmatic power supply reboot
RS-485
- https://www.olimex.com/Products/Modules/Interface/MOD-RS485-ISO/ galvanically isolated, full/half duplex, I2C interface, can be used in conjunction with Debug UART and RS-485. It is possible to connect more than two devices.
- https://www.olimex.com/Products/Modules/Interface/MOD-RS485 - half duplex, uses UART. Up to two modules.
Contactless card readers and keyboards
Wiegand
- Connect the lines D0 and D1 of the readers to the GPIO through a resistor 1-20 kom! (on Wiren Board 2.8)
- See https://github.com/contactless/wirenboard/tree/master/examples/wiegand
