2Walkera WK-0701 transmitter is supplied with a ready to fly Walkera

13Connecting to PC:

15At back side of transmitter S-video connector can be found. Modulation
16pulses from processor to HF part can be found at pin 2 of this connector,
17pin 3 is GND. Between pin 3 and CPU 5k6 resistor can be found. To get
18modulation pulses to PC, signal pulses must be amplified.

36Software:
37
38Build kernel with walkera0701 module. Module walkera0701 need exclusive
39access to parport, modules like lp must be unloaded before loading
40walkera0701 module, check dmesg for error messages. Connect TX to PC by
41cable and run jstest /dev/input/js0 to see values from TX. If no value can
42be changed by TX "joystick", check output from /proc/interrupts. Value for
43(usually irq7) parport must increase if TX is on.

81to bin change or octal value to bin change).
82
83Binary data representations:
84
85One binary and octal value can be grouped to nibble. 24 nibbles + one binary
86values can be sampled between sync pulses.
87
88Values for first four channels (analog joystick values) can be found in
89first 10 nibbles. Analog value is represented by one sign bit and 9 bit
90absolute binary value. (10 bits per channel). Next nibble is checksum for
91first ten nibbles.
92
93Next nibbles 12 .. 21 represents four channels (not all channels can be
94directly controlled from TX). Binary representations ar the same as in first
95four channels. In nibbles 22 and 23 is a special magic number. Nibble 24 is
96checksum for nibbles 12..23.
97
98After last octal value for nibble 24 and next sync pulse one additional
99binary value can be sampled. This bit and magic number is not used in
100software driver. Some details about this magic numbers can be found in
101Walkera_Wk-0701_PCM.pdf.
102
103Checksum calculation:
104
105Summary of octal values in nibbles must be same as octal value in checksum
106nibble (only first 3 bits are used). Binary value for checksum nibble is
107calculated by sum of binary values in checked nibbles + sum of octal values
108in checked nibbles divided by 8. Only bit 0 of this sum is used.
