I have custom PCB's for product that I've been building myself. I took a launchpad and soldered a ZIFF socket on so I could swap chips quickly. I was programming them through the energia interface.
I built about 150 of them myself. Programming all 150 maybe took 1-2 hours not bad; however I'm going overseas to build not only my PCB but my entire assembly. Obviously the language barrier can be tricky sometimes. They currently supply my wire/cut/stripped/tinned etc so I've dealt with them before, but I'm not sure how the programming will go since they are going to be building the entire thing.
I'm guessing if I just send them my energia sketch they aren't going to know what to do with it, as they're more familiar with large scale production. So, I guess i'm just trying to feel out what the 'industry standards' are. Can I just have energia compile my sketch and send them that and they'll know what to do with it. My problem is I don't really understand much about programming outside of the energia/arduino interfaces.
