Now will DS2431 via a 2 m long line connected to the MCU, there also some adaptor, but wave type is very poor, read the unsuccessful
Q: is there any good solution to make the drive ability, because it is a single two-way transmission, the appropriate driver chip? thank you
CodePudding user response:
External pull-up resistors have? General 2 m can be read directly,Single bus general requirement on the external pull pull-up resistors, about 5 k
Share use of the single bus temperature sensor DS18B20 experience before, about 1 m to 2 m long, and
When using ordinary wire extension, no data has been read,
Then use the shielded wire, data stability,
The hope can help the building Lord,

Was tried on 2 ~ 10 k, difficult to really cable? Still good DVI cables, I use this signal as long as the plug in, boot wave type is wrong, will some more clutterCodePudding user response:
DVI wire interference would go in with the string joint proposal in line,Can have a try in ordinary wire, to separate the power cord and signal lines, to see whether the power coupling interference,
Best control variables, find out the problem, many experiments,
Because of this communication is not stable and the surrounding electromagnetic environment also has a relationship,
