I'm waiting for my Stellaris boards to ship, and they won't be here until December at the earliest, so I thought maybe while I'm reading about ARM development I'd also try my hand at something a little more low level. I'm fairly comfortable with AVR development and one of the things I love about it is that you can pop a chip on a bare breadboard, add a power brick, voltage regulator, a few caps, and you've got a running "board" that you put together with your bare hands. Not that there's anything wrong with prefabbed boards like the Ardiuno or Stellaris, but there's a certain satisfaction that you get putting bits and pieces together. So I'm starting to think of possibly putting together an ARM breadboard solution. Stellaris M4 chips seem to be hard to come by so I'm probably going to either use a Stellaris M3 or one of the NXP M3 chips. One of the things the NXP has is a USB bootloader so (it looks like) I can just wire up a USB port and drop my firmware onto the chip right from my desktop with a minimum of work. I'm not sure if the Stellaris family offers something like this, I haven't dug through the datasheets extensively just yet but that's on my list of to-do's. So my question: Has anyone here tried this bare-bones approach before? I know getting a LQFP chip on a breadboard isn't going to be easy, but there are several prototyping options which would let me keep the chip itself off the breadboard and wire up everything I need with cables. I'm still going through datasheets trying to figure out exactly what other components the chip will depend on being present, but it seems to have internal oscillators and such, so I'm thinking this won't be a royal pain to put together. Anyway, apologies in advance if this doesn't belong in the Stellaris section. I'm not 100% sold on using the Stellaris chip yet, but it's in the running. This is really more of a "generic ARM" project since it's more about the hardware than the specific vendor implementation. Cheers! Quote Link to post Share on other sites
