The Tinys have USI which is ok but less powerful. Hi, Thanks again for your valuable information and responsiveness. I think that there must be one Vcc for master and slave.

The application should be prepared to wait for this ownership.
This interface can be used for communication with a I2C devices, such as serial memories, sensors Remember, you will need a pull-up resistor on sda and scl.

If pullup resistors are needed for I2C on LPC what value of and bus capacitance, you need to ensure signal rise time conform to spec. mBed.
Expected behavior. I2C bus are usually 5V tolerant on all If a feature of a I2C open drain pull-up by the MCU is required, then a new.

So i have to stick with their design, and adapt my code to it! Posted by manulrk : Sat. If you plot the glitch peaks, it looks almost like a straight line possibly excepting the 3rd one.

*/. /*! . Requested clock speed exceeds operational specification. *. * Sets the highTime16 = halfClock16 - 7u; /* empirical: varies with board layout, pullups, etc */.

The sensor module has built-in K pull up resistors on the SDA and SCL lines as required by the I2C specifications. The Construction Fig. shows. If I will explicitly disabled the Arduino internal pullups via code (using The HAT Specification says that in order to use those pins for i2c you.
I think that there must be one Vcc for master and slave. Sign in to your account.
The fact i didn't used external pullups is that it is a commercial ready made board, where i modify the firmware.
