Hello,
Im intresting in your new product esp32.
I read on the data sheet about the I2C interface.
I saw that there are two options of data rate, 100kb/s (standart), 400kb/s (fast).
I want to know if there any option to work with the I2C with higer data rates?, and if so what is the maximum data rate?
Thanks!
I2C maximum data rate
Re: I2C maximum data rate
Hello Yakir
I did try to push i2c com speed and did not see any problem setting up the driver to 800 kbps. Communication was ok - if you have the right (externl) pull on the i2c bus.
I did notice that one of the clock pulses (between data and ack ) do not seem to get scaled with the faster clock setting - Still need to report to Espressif.
Regards Jørgen
Plot of 400kbps with extra delay between last data and the ack clock
