VCC2 VPP I0 GND2 T1 TxD R1 R2 OK1 1 6 5 2 4 R3 RxD R5 CNY17 GND2 GND GND Fig. 10. 10 Basic Principles of Networking with Microcontrollers 45 The current generated by I0 closes to the ground either through the transistor T1, when this is saturated, or through the LED of the optocoupler OK1, when T1 is blocked. As a consequence, the waveform of the signal in the collector of the optocoupler’s transistor reproduces the TxD signal. Such a circuit can be used for point-to-point communication systems to transmit data at 9600 bps, over cables a few kilometers long.

8 Programming the Asynchronous Serial Interface 37 In the operating mode 0, the interface acts like a serial shift register. The serial shift clock has a fixed frequency, equal to f osc /12. Eight data bits are transmitted, starting with the least significant bit (LSB). In mode 1, 10 bits are shifted from (to) SBUF: one start bit, eight data bits (LSB first) and one stop bit. The communication speed is variable and programmable using the system timer. In operating modes 2 and 3, nine data bits are sent, packed by a start bit and a stop bit.

Waveforms illustrating the level conversion performed by MAX232 power supply. Most of the projects described in this book use this circuit. The schematic of an RS232 interface using MAX232 is shown in Fig. 6. 7 shows the waveforms of a signal before and after the MAX232 driver. 2 Differential Communication. The Interfaces RS422 and RS485 The RS232 interface guarantees safe transmission up to a distance of 15 meters, at a maximum communication speed of 19 200 baud. In practice, these limits are often exceeded, but the overall reliability of the communication system drops.
