[beagleboard] Re: I2C SCL Voltage level too low?

With the 1k resistors improvement is evident in terms of voltage level for the high signal. However the rise time still seems to be slow and I2C device is still n

Re: [beagleboard] I2C SCL Voltage level too low?

I only managed to get hold of a couple 1k resistors and wired them up to the 3v3 rail and got improvements. I am going to assume the internal pullups on the I2C device were not enabled.

Re: [beagleboard] I2C SCL Voltage level too low?

You mean decrease the resistor values. Don’t rely on the internal pull up resistors. 4K7 should be OK, but try 3K3 to see if the signals look better. Regards, John > On Apr 4, 2018, at 10:06 PM, yassyass wrote: > > Thanks Wulf, I will attempt to increase the resistor values and get back w
