Hardware setup

To configure the hardware board, the user should follow these steps:

Jumper settings: There are four jumpers (JP1, JP2, JP3 and JP4) available on the

board. The detail of these connectors is as follows:

JP1: JP1 pins should be connected using the jumper if there is no pull-up

connected in the clock line of the I2C bus. Once connected, the I2C clock line is

pulled up with a resistor value of 4.7 k

Ω.

JP2: JP2 pins should be connected using the jumper if there is no pull-up

connected in the data line of the I2C bus. Once connected, the I2C data line is

pulled up with a resistor value of 4.7 k

Ω.

JP3: JP3 is used to select the clock source for the ST7 microcontroller. From the

JP3 side, if the jumper is connected between pins 1 and 2 then the application
