Recently I started laerning about ARM (LPC2148) and found Keil, IAR and Rowley GUI environments. I read their documentations and user comments and to me it seems tgat Rowley Crossworks is what suits me the best (it is not as complicated as Keil or IAR). I have some problems with JTAG Wiggler in Rowley CrossWorks 1.7. I made the JTAG Wigler clone similar to Leon's design (with 74HC244). ...

The latter was rather short so I swapped it for the cable from my CrossConnect Classic. It required a new ...

Hi all, Okay, I know this is the LPC2000 forums but there still aren't any good Cortex forums... plus the Rowley guy regularly trawl this forum :) This issue may affect anyone using GCC and ARM7s as well so I don't feel too guilty for posting here. The scenario is that during power-on the Cortex M3 waits for its oscillator to stabilise. Once done, off we go. If it fails then it star...

I'm evaluating cheap compilers and it appears Keil is 16k limited for eval and IAR is 32 limited for eval. Both reasonably generous for learning I suppose, though I'm sure there are some gotcha's in there somewhere. So I'm also looking at Imagecraft's compiler (I've used them before with HC11 and PSoC) or maybe Rowley CrossWorks. I'm not worried about GCC's code density but I am worried t...
