Question
Signal sniffer
Hi everyone.
I have a position encoder connected to a motor drive. The encoder transmit every 0.1ms a 73-bit data package using a protocol called EnDat 2.2 to the drive. The clock frequency is set to 5MHz, meaning one bit is 0.2 microsecond.
Now I want to "sniff" this signal using STM32 without disrupting the connection between the encoder and the drive, meaning I won't send any signal to the encoder nor the drive, I just want to "eavesdrop". For example 150 bits every 1 sec.
Do you know how to do it or what kind of protocol I have to use? Would SPI work?
Thank you in advance
