Ok, the protocol is right, cause it works with HW USART. I have put in the fast_io thing. the output_b(0x09) doesn�t matter for communication, it�s only relay reset and LED control. Maybe the Nokia i ... |

ahmm shift_right out to the pin is right at put_char, cause LSB is first. And in get_char() the bits are shifted left in, so the LSB is the first who is in. I think that is right. I have tried it with ... |

No, the problem is, i need 115kbps connection inverted on PIN_C6 and PIN_C7. Because the circuit board is already made. I have realized too late that i need inverted output to control the IR transceiv ... |
