ZigBee's serial Learning

Regardless of which MUC serial port for our experimental debugging is very convenient and practical, we can be involved in the program of some intermediate or other program state information printed out to display on the computer for debugging, many MUC and PC communication is carried out through the serial port. ZigBee is no exception.

The USART mode operation has the following characteristics:
1, 8-bit or 9-bit load data
2, odd check, even check or no parity check
3. Configure the start and stop bit levels

4. Configure LSB ( least significant bit ) or MSB (the most significant bit) is transmitted first

LSB (Least significant bit), meaning the least significant bit, MSB (most significant bit), which is the most significant bit, if msb=1, indicates that the data is negative and if msb=0, the data is positive.

5. Independent Transceiver Interrupt
6. Independent Transceiver DMA Trigger
