While debugging an I2C problem I found in soft_i2c_read() and soft_i2c_write():
if(write_byte(addr >> shift)) { PRINTD("i2c_read, address not <ACK>ed\n"); return(1); }
and
if(write_byte(addr >> shift)) { PRINTD("i2c_write, address not <ACK>ed\n"); return(1); }
This means that these functions are left without sending a STOP condition to the bus and with SCL held low. Is that really intended?
