hey guys
just wondering if anyone is familiar with the SSI interface (serial syncronous interface)
it is unidirectional communication technique on rs422 drivers for long distance
the problem i am having is inconsistent readings on a very short 10 feet cable !!
the inconsistacy is usually one bit and is never in the same place so data is received but distorted and off course this protocol doesnot require checksum or correction bits .
note : i am using a PIC microcontroller at 40mips , 2 simple GPIO for the communication at 100khz to 1Mhz clock, with serial com at 9600 port to view the data on PC . and very simple software which i am sure is 100% working
so any advise on solving the problem , could using dedicated SPI module with manual manipulation of the configuration bits be done to improve the results ?? could i use schmitt triggers and filter ?? or a specific ICs latches for hardware decoding
