Hardware Overview
MT3620 Grove Shield
Since Azure Sphere SDK has not yet supported ADC and I2C on MT3620. This shield serves as an interface between MT3620 UART port and external I2C devices, like the I2C temperature sensor. The basic function of the shield is to help to connect to I2C external device. By using an I2C compatible ADC chip, developer can also read the analog data from analog port.
MT3620 Grove Shield includes 2 chips, AD7992(Anlog to I2C) and SC18IM700(I2C to UART) to enable the ADC and I2C function from hardware side. So the analog sensors' signal go through AD7992 and then SC18IM700 to UART of develop board. The I2C sensors go through SC18IM700 to UART of develop board as well.
The AD7992 is a 12-bit, low power, successive approximation ADC with an I2C-compatible interface. It transforms the anlog signal A0, A1 to I2C data.

The SC18IM700 is designed to serve as an interface between the standard UART port of a microcontroller or microprocessor and the serial I2C-bus; this allows the microcontroller or microprocessor to communicate directly with other I2C-bus devices. It transforms SDA/SCL signals to GPIO26_TXD0 and GPIO28_RXD0.
