7-bit clock cycle Read(Rx) and Write(Tx)

[MagnusPer]

Hi,
Trying to decode my hot tub communication to make it available wireless. From my initial measurements I see the clock cycle is 7-bits and not 8-bit that is standard SPI. I see in the SoftSPIB library can configure transmission(Tx) but how about reception(Rx).

Hi! I've neve tested the read feature. It was not needed in my application.
Looking to following code fragment present in function uint16_t SoftSPIB::transferBits(uint16_t val, uint8_t bits):

'''
bval = digitalRead(_miso);
if (_order == MSBFIRST) {
out <<= 1;
out |= bval;
} else {
out >>= 1;
out |= bval << (bits - 1);
}
'''

The read feature should work. Try it out
