Original problem was discussed here (http://www.tinyclr.com/forum/topic?id=11116&page=1), but I started a new thread to separate 2 different problems.
My question is which protocol (approach) should I use if connecting 2 micro-controllers (chips) (in my case Spider - Cerb40, Cobra II - Cerb40) on “long” distance.
My distance is around:
a few inches
1m (3.28 feet)
2m (6.56 feet)
10m (32.81 feet)
30m ( 98.42 feet)
50m and more (164.04 feet) [/ul]
Let’s say we want 100% correction. I think that means some CRC. The discussion is meant to help me (and possible someone else) which protocol should I use (I2C, SPI, UART, RS232, RS485, CAN, … when connecting 2 devices.
