Full Duplex Serial - rosco-pc/propeller-wiki GitHub Wiki
(and other asynchronous serial variations)
| Full Duplex Serial | Created by: Chip Gracey | The original "Full Duplex Serial" |
|---|---|---|
| Extended Full Duplex Serial | Created by: Martin Hebel | Extensions to allow reception of character strings that end in a carriage return for decimal, hexadecimal and alpha-numeric uses. Allows use of timeout values. This version also allows use of defined delimiter characters, and returning whole and fractional portions of a numeric string. |
| Simple Serial | Created by: Chip Gracey | Bit-bang serial driver for low baud rate (~19.2K) devices. |
- This driver is designed to be method-compatible with the FullDuplex serial object, allowing it to be used when high speed comms or devoting an independent cog for serial I/O is not necessary.
- Bi-directional communication on the same pin is also supported. | | SerialMirror | Created by: Mirror | A FullDuplexSerial enhancement that allows a single serial connection to be used from within multiple spin files. Primarily aimed as a debugging aid, this file also illustrates how to use the DAT section to make single-instance objects which may be called from multiple spin files. |
Designed for serial communications.
Examples of this code in use: PropCOMM,
.start(rxpin, txpin, mode, baudrate) Start serial driver - starts a cog mode bit 0 = invert rx mode bit 1 = invert tx mode bit 2 = open-drain/source tx mode bit 3 = ignore tx echo on rx
.rx(rxbyte) Receive a byte of data
.tx(txbyte) Send a byte of data
.str(stringptr) Send string. Example: str(string("Hello World"))
.dec(value) Print a decimal number
.hex(value, digits) Print a hexadecimal number
.bin(value, digits) Print a binary number
