A came upon this the other day, and was so impressed that I'm about to drop $60 on an lpc1768, which is the primary MCU they are using at the beta stage (they plan to expand to others once the API is solidified). They also have used an stm32f4, which I do have at the moment, but support for it seems to have dwindled over the past few months. But I really like the safe way they are developing the API. Even the hardware configuration is done as a safe DSL. Very impressive. This project looks like a great foundation for a realtime OS in Rust I've been itching to try my hand at.

  Yeah, I should have specified the eval board, which includes peripherals. This Zinc project already has support for several of the peripherals, including a few TFT drivers, which I want to be able to try out. I don't always buy eval boards -- if a chip comes in a DIP package, I've just breadboarded it in the past. As a hobbyist, I haven't yet tried to build a breakout board for any SMT-mounted chips, but it's on my todo list. The one I'm looking at (by RioRand) is not a bad deal, since it actually includes a 2.8 inch TFT on the board as well as Ethernet interface. But I did consider just buying the chip and breadboarding it. I may still do that and buy the LCD separately. $60 would indeed be expensive for the chip alone.

    BTW, you cand find cheaper boards or with more peripherals from China, just check out eBay or aliexpress

      Yeah, I know I can probably get the eval board a bit cheaper -- I've bought chips from China on ebay and frequently look at TFT LCD displays on aliexpress while dreaming of a commercial product I'd love to do some day. But in this case, I don't want to wait 2-4 weeks for delivery. The RioRand will be here in 2 days since it's on Amazon Prime.
