Hi guys, Iam a brand new in microcontroller world and Iam looking for someone who can help me to find demo code, which will preserve a communication with LPC-P2148 development board via UART. I have a RS232 USB converter and I want to upload hex files via UART but I cant find useful Eclipse Makefile (which shoud include settings like: com, port, baud rate, ram, rom). Does anybody have the starting project with this makefile to me? Thx, Jan.

Loading hex-Files via uart requires the presence of a bootloader in the Controller. If there is no bootloader pre-flashed from the board manufacturer, you will need a JTAG programmer to program the controller. If there exists a bootloader, the best source to find further information on this will be the documentation of your specific board. Oliver
Hi Oliver, thank you for you answer. I split together two makefiles and now I am able to upload data to my board via software called LPC21isp, so Iam glad i made run my demo code. Next step is to make run a timer. I know it is hard. I need timer to run, I mean to count in real second. Does anybody know how to make it? Respectively, how to set timer registers to count in seconds. Thanks, Jan.
