About 14-18 months ago, I did some work on a 5509 + CC1101 USB stick that was a poorly-kept secret. It seems as though TI finally got the bugs out of the board and started replenishing their Chronos kits with it. In the users' guide, TI refers to the old kits as "BLACK" and new kits as "WHITE". Of course, it is the silkscreen they are talking about, but the boards are entirely different. Anyway, I would make sure to get the WHITE Chronos. The BLACK RF Gateway uses a CC1111, which is an 8051 core with an entirely different toolchain. The WHITE one can use the normal MSP430 toolchain. The 5509 is better than the CC1111 is terms of power (8051 is slow and has poor code density), but it is still a bit anemic (24KB/6KB). I can't really figure why they didn't use the 5503, considering that the ADC is unused, but I guess TI probably makes more 5509s, so it is easier for them to source (just guessing). Last year when I was working on this kit, I did manage to squeeze a full server build of OpenTag on it. I don't think other cool stacks (namely Contiki) can fit, but it might be worth a shot. In any case, it's a lot more hackable than the old kit was. Automate 1 Quote Link to post Share on other sites
