wire.h issue on arduino #1

Open mash-m opened 7 years ago

mash-m commented 7 years ago

Hi,

i´m trying to get your script running on a feather m0, but it seems that the wire.h had changed,

"'class TwoWire' has no member named 'transfer'"

i did´t found any usefull information about your method for reading and writing data via i2c (wire.transfer). maybe you can help me to reqrite the i2c read/write function in your scrip. basicaly i kown that there are now some other commands for wire.h:

thanks, markus

Use whatever you usually use on the Feather for I2C read and write then.

I'm very curious where the "Wire.transfer()" comes from.

I have searched online and read this: https://github.com/kriswiner/Dragonfly/wiki/B.-Using-Wire-(I2C)-with-Dragonfly but I'm still in the dark.

It's part of the STM32L4 Arduino core.

Thanks. I see it is in the GrumpyOldPizza Wire library. But that is the only place I can find it.

That's the only place it should be...
