when compiling code from photon to photon 2 the I2C gets broken: I always get 370kHz clock while i do a "Wire.setSpeed(20000)" and expecting a 20 kHz clock.
( does work on photon )
I'm using 5.5.0.
Can somebody explain me how to reduce the I2C speed on photon 2?
On the P2 and Photon 2 the only valid values are
CLOCK_SPEED_400KHZ. Other speeds are not supported and if you specify an unknown value it defaults to 400 kHz (approximately).
will that change in the near future or does that mean we cannot use photon2 ?
It looks like the hardware supports it, so I created an engineering ticket to examine whether its possible to support custom I2C speeds on the RTL872x in the future.
thanks very much for the swift answers,
