Peripheral UART[edit | edit source]
Description[edit | edit source]
The Universal Asynchronous Receiver/Transmitter (UART) interface available on ORCA is based on iMX8MPlus SoC.
UART provides serial communication capability with external devices and support NRZ encoding format, RS485 compatible 9 bit data format and IrDA-compatible infrared slow data rate (SIR) format.
The UART port supports the following standards and features:
- High-speed TIA/EIA-232-F compatible, up to Mbit/s
- Serial IR interface low-speed, IrDA-compatible (up to 115.2 Kbit/s)
- 9-bit or Multidrop mode (RS-485) support (automatic slave address detection)
- 7 or 8 data bits for RS-232 characters, or 9 bit RS-485 format
- 1 or 2 stop bits
- Programmable parity (even, odd, and no parity)
- Hardware flow control support for request to send (RTS_B) and clear to send (CTS_B) signals
- Two independent, 32-entry FIFOs for transmit and receive
Pin mapping[edit | edit source]
The Pin mapping is described in the Pinout table section
