I know i can control i2c devices with the same device id on different channels, but can i also control 4 or 3 i2c devices with different i2c id´s on for exapmple the first channel.
My problem is, that i my sensors have 4 divices with different addresses and i want to control each on 3 times or more in the futur. So my question is if i can control in my case a device with 0x30 and 0x31 on the same channel 1 of the PCA9548A 8 mux?
Thanks
yes. You could, for example, have 8 devices at 0x30 and eight at 0x31, as long as one of each is on each channel of the PCA, and you appropriately select the correct PCA channel before communicating with each pair.
You can put as many as you want on a single bus as you have different addresses for each of them. Many have A0-A2 as address select, that will allow 8 of them on a single bus.
