OWWRBYTE | Example |
OWWRBYTE Pin, ByteVal
Function
Writes one byte (eight bits) to the 1-Wire bus.
Quick Facts
All SX Models | |
Special Notes | The DQ pin (specified by Pin) must have a 4.7 kΩ pull-up resister. |
1-Wire commands require a FREQ setting of 4 MHz or higher. | |
Transmission rate | ~12 kBits/Sec (not including Reset) |
Explanation
After reset, 1-Wire transactions require writing values to the bus. A bit is
written by generating a timed low pulse on the DQ line; this is called a
"Write Slot" (see OWWRBIT for details). The OWWRBYTE instruction
generates eight Write Slot sequences to put ByteVal on the 1-Wire bus.
