software i2c?

[navanod]

Ive run out of pins to use i2c on my blue pill and would love to try software i2c. I cant see any in the example but perhaps someone else has some more info?

I've move this topic in libmaple core section as softWire is only available in this core.

1 need 3 i2C devices in this blue pill while at the same time 12 hardware PWMs pins. Either core wouldnt bother me if I knew it was going to work...either that or porting the softwire to the other core.... ?

[fpiSTM]

Well you can connect several I2c device on the same I2C instance...

[navanod]

these particular i2c devices dont have a changeable address..its the as5600.

You might find some useful info in this pdf from STM.

you may want to consider switching the bus so that at a given point only one device is on the bus.

Much easier than having a gazillion i2c buses.

A TCA9548A module for a couple of dollars looks to be an easy hardware solution. I've never used one, but the description of the part seems to fit the requirement: See this link.
