I am new to keil c programming, First, you need to read the uVision Getting Started guide, and work through the examples projects in it. You will also need to read the C51 Manual Are you also a newbie to 'C' programming in general? If you are also a newbie with the 8051, you need to read the following documents - commonly referred to as "the bible" for the 8051: http://www.semiconductors.philips.com/acrobat/v...ARCH_1.pdf http://www.semiconductors.philips.com/acrobat/v...UIDE_1.pdf http://www.semiconductors.philips.com/acrobat/v...WARE_1.pdf And these may also be helpful: http://www.keil.com/books/8051books.asp http://www.8052.com/books.phtml http://www.8052.com/tutorial.phtml panitini madhu satyanaray said:
I want store each byte from serial port buffer to xdata buffer.
how define the buffer at particular memory loaction Why do you want to define it at particular memory location? In general, there is no reason to do this. If you really have to, look up the _at_ keyword extension in the C51 Manual. panitini madhu satyanaray said:
store byte after byte by incrementing the xdata buffer. You don't increment the buffer - you increment the pointer or index into the buffer. The Interrupt-driven serial IO example on the Keil site shows you how to use a Circular Buffer to do this: http://www.keil.com/download/docs/intsio.zip.asp Or look at Mark Odell's example: http://www.8052.com/users/emb...Driver.zip |
