I'm currently doing a project in arm lpc2148 as main project for my college. I want to send certain integer values from pc via serial port to the lpc2148. the arm code is an infinite loop searching for the integer value and the value is stored in an array or buffer how should i do that plz help
What do you expect? Ready made code where you just have to insert your name that solves the task and satisfies your teacher? Just start and ask more specifically if you run into problems.
i wont say that i want the readymade code. just tell me how to do that ie communication between pc and arm (sending messages in both direction)
The LPC214x controller offers USB and UART interfaces. For a start it's much easier to use the LPC's UART. If you PC does not offer a serial-port you can use a usb-serial cable available in nearly every computer shop. You need an interface-IC like i.e. a MAX3232 between LPC and PC's serial-port. Just look into the schematics of LPC214x evaluation boards for hardware-details. Example-code on reading from/writing to an LPC UART can be found in the net (i.e. in the sample-collection fro LPC213x/214x from NXP.com, example-code from Bill Knight in the LPC yahoo-group). Once you are familiar with developing code for the LPC you can start using the LPC's USB-interface.
