PC or USB serial port. This interrupt or status bit is automatically cleared by writing to the. Hello, Prints 'hello world' to the terminal ( RS232 port ). I2c, Block read/write from/to EEPROM using I2C. Include, Including other files in BASIC programs. Incr, Increments a variable. Inkey, Reads a value from the serial port. Input, Inputs data from RS2323 serial port to a variable. Int0, Interrupt handler demo for INT0 of 8051. C# serial port loop interrupt. Ask Question. I want to send and receive data from a Serial port in a Loop (some voltages in a loop like 200ms).

Data can be exchanged using parallel or serial techniques. Setup for parallel data transfer is not cost effective but is a very fast method of communication. Serial communication is cost effective because it requires only a single line of connection but on the other hand is a slow process in comparison to parallel communication. This article explains serial communication of AVR microcontroller () with PC. The data is transmitted from the controller using RS232 standard and displayed on the PC using Hyper Terminal.

I know what code I am supposed to get, but it's not working, and Im running out of time. >>>mark@mcselec.com 07/11/01 12:32AM >>>Hi, The serial buffered input/output is inteded for the hardware uart.

When you use INPUT,INKEY or WAITKEY you are doing serial input. Normally this returns info from the serial port. But what happens if you are in an interrupt or performing a time consuming function?

The hardware uart can only store 1 byte. So that is why I wrote the buffered routines. The buffered input routine will store the incoming data in the buffer. Then when you use INPUT,WAITKEY etc., this data is pulled out of the serial buffer.

The variables mentioned in the sample are only there for completeness.
