First I want to say how impressed I am with the Teensy line. They are terrific products and I am having a ball using them.
I am starting a more ambitious project that has several asynchronous functions in it and I don't feel that one uC will be able to handle everything without timing issues. My plan is to off load these separate functions to LCs or 3.1/2s and have the whole system be controlled by a 3.5/6. Eventually, I may spin a custom board for this system. That board won't have some of the functions that are build into the Teensy. For example, there won't be SD cards or a USB connector for each uC.
I have two basic questions.
PROGRAMMING:
I have been doing all the programming through the USB connector. What is needed and what is the process for programming directly through the program pin?
CONTROL ARCHITECTURE:
The 3.5/6 has to communicate with the LCs and the 3.1/2s. What architecture would you recommend? CAN?
Thanks for your help and suggestions.
