 The sbus protocol is a 100 kilo baud serial protocol (1 start bit, 8 data bits, 1 even parity bit and 2 stop bits). Every 7 milliseconds a packet of 25 bytes get sent by the receiver. The packet is made up of a start byte, 22 data bytes, one flag byte and an end byte:
 
-[start][data1][data2][data3][data4][data5][data6][data7][data8][data9][data10][data11][data12][data13][data14][data15][data16][data17][data18][data19][data20][data21][data22][flags][end]

 The start byte is 0x0f and the end byte usually 0x00. Remember these are the values the teensy sees after the sbus protocol has been inverted by the transistor. The teensys UART needs the inverter to recognize the start bit (low), partity bit and stop bits (high).
