Arduino Tian

this goes other arduino boards similar designs:

is possible microprocessor use microcontroller?

i understand io pins tied microcontroller.

all see processor controls usb, blutooth , wifi, has no influence on connected microcontroller through io pins.

also, not see many projects use processor/controller paired design.

thanks!

the classic pairing of host computer , bare metal device taking care of business guess. have been using pi 0 host paired bare metal avr's more , more. basically, bare metal program command processor , send commands pi desktop. bare metal performs operations , records sensor data synchronized operations. pi can read sensor data in sync operation. based on have been doing connection between microcontroller , microprocessor needed serial (uart).  suspect spi connection may useful also, other pins should go headers user applications.

i use pi because can put avr toolchain on it, , serve samba area firmware , ssh compile , upload. means don't have map raw serial port pi development machine since pi can host development tools itself.
