I am new in embedded programming. Actually I want to run a c program that have used LPC21xx.h header file. I have tried keil uvision 5 and keil uvision 3 both. In keil uvision 5 there is no device with LPC2129 and in keil uvision 3 there is LPC2129 after selecting that device. It is giving me error like "path for toolset undefined. C:\keil\tools.ini does not contain a tool path. you have selected a device with no toolchain has been installed ." i went to c:\keil\tools.ini and there is a path under c51 PATH="C:\Keil\C51".
please let me know where is the problem. if there is problem in setup file for keil uvision 3. then please provide me some link to download keil uvision 3 or keil uvision 4 setup because it is not available on keil site.
Hi Mahaveer, you need to install legacy support for ARM7 devices. In KEIL 5 you need to download the install support packs for the family of microcontrollers that you want to use.
Check out this article guide on using keil for lpc21xx devices : www.ocfreaks.com/.../ It for lpc2148 but its the same for all lpc2100 series microcontroller.
Hope it helps.
