I2c Example 2022

This feature is implemented as a 12-bit counter with the upper 8-bits being programmable. To reduce the number of pins several serial protocols have been developed to transfer data between ICs. I see a few I2C examples in user-mode. - esp-idfi2c_example_mainc at master espressifesp-idf.

I2c Example 2022. Routing to these peripheral devices can be a challenge. In the I2C peripheral. For example the HMC3843 has an I2C address of 0x1E or 0b00011110 but if we want to send a request to read from our device we have to send it the address 0x3D or 0b00111101 and to send it a request to write we send it 0x3C or 0b00111100.

One of the most common uses of an I2C IO expander is to control inputs that are located remotely on the PCB. Since the SCL and SDA lines are open drain type we use the tristate control register to control the output keeping the output. Note Not all Tiva.

One such protocol I2C uses only 2 bidirectional open-drain wires. For example to program a timeout of 20ms with a 100-kHz SCL frequency ui32Value is 0x7d. Sensors and actuators are common use cases for I 2 C.
