TCA9548 - change frequency - fast mode #11

Closed Anomis28 closed 11 months ago

Anomis28 commented 11 months ago

Hi I need to increase the acquisition frequency in my application in which I have multiple sensors connected to the TCA9548A, by using the available library my frequency is slow, How can i get the switching frequency of the multiplexer? And how to operate in fast mode? Thank you

Thanks for the issue,

Which board are you using? If the sensors can have multiple addresses it is faster to keep them on a single I2C channel

Furthermore you might improve by using Wire.setClock() See - https://www.arduino.cc/reference/en/language/functions/communication/wire/setclock/

If that is not fast enough you might have a look at - https://github.com/RobTillaart/HC4052 That will switch faster but takes more pins.
