Now that we have written and tested a couple of programs, it is time to connect the AVR processor to the PC. The simplest port to connect to, on the PC, is the RS-232 serial port. You may want to read the operation of the RS-232 port in detail, presented in a later chapter. Many of the AVR processors are equipped with a built-in serial port. On the entry-level processors such as the AT90S1200, one can create a software-driven serial port. This section presents both of these methods. Of course, it is very easy to use the builtin serial port of the AVR processor with only a few instructions. The processor takes care of serializing and shifting out the data on the output pin and assembling the incoming data into a byte. The user needs to set the serial port parameters such as the baud rate (which indicates the bits per second), the number of bits in a transmission, number of stop bits, and parity bit. The processor can generate most of the standard and popular baud rates with a suitable clock frequency.

The serial port of the AVR cannot be connected to the PC serial port rightway. The RS232 signals are bipolar and in the range of 12 V and 12 V while the AVR can only han, dle TTL-level signals (if powered from a 5-V supply). Also, the data as appears on the RS232 line is inverted. That is to say that when the PC wants to send a logic 0 , the voltage on the RS-232 line is 12 V and when the PC wants to send out logic 1 , the line voltage is , 12 V So some sort of RS-232 line driver and receiver that converts the RS-232 signal lev. els to TTL, and vice versa, is needed. Also, performing the signal inversion is needed. A very popular RS-232 line driver and receiver that I have extensively used is MAX232 from Maxim, as well as the pin-compatible ADM232 from Analog Devices. The circuit schematic for the RS-232 interface is illustrated in Figure 6.19, appearing later in this chapter. The following piece of code shows how to set up the built-in serial port (called UART in the AVR datasheets) of the AVR processors. The following program is also available on the CD in the code directory as file uartdrv.asm. The code is executed on the circuit illustrated in Figure 6.4. I have chosen to use the AT90S8515 for this exercise. The 8515 is connected to the PC serial port through a MAX232 level translator chip. On Windows or DOS, run any terminal emulation program and set the baud rate to 9600, 8 data bits, 1 stop bit, and no parity format. Now type any key; the 8515 will light up the ASCII code of the key on the eight LEDs and also increment the code and transmit it back. So if you press A , it will send back B and so on.
