Three-state buffer SPI termination requirements

You obviously don't use the third high impedance state of the drivers, they are just used as level shifters. During reset or firmware update the MCU may have undefined voltages at the SPI pins. ...

CAN Bus termination resistor in only 2 device connection

Termination resistors and why you need them CAN and RS485 phsical layers use square pulses at high frequency to move data about - in fact the frequency of these pulses is high enough that you must ...

CAN Bus termination resistor in only 2 device connection

The number of devices is irrelevant. Bus type is. CAN bus is open drain type, which relies on the termination resistors to return the dominant bus voltage back to recessive bus voltage. So it does not ...
