I2C Timming Problems
Juan Pablo Jimenez
Hello. I'm trying to communicate with an I2C accelerometer(MMA8452Q) but im having problems getting a response.
I plugged a oscilloscope and I found that there is an "idling" that is way too long and makes the accelerometer communication timeout or something.
I have done it via the terminal and via python(with python the idling is even worse)
I tried the same request with an Arduino and worked fine. The only difference I can see is the "idling"
Does anyone has an idea about this problem or a workaround?
Thank you very much.
I am reading the register 0x0D and the device address is 0x1D
< i2cget -y 0 0x1D 0x0D >
THE BOTTOM ONE IS THE ARDUINO WITH THE CORRECT RESPONSE
