Is it possible to parallel connect Azure Sphere MT3620 with another microcontroller?

Question

I am working on an Azure Sphere project based on the MT3620. I am a beginner with azure sphere and I have a basic question. I am wondering if it is possible to parallel connect the MT3620 with another microcontroller like arduino or stm32 to transfer data between them and if it is possible I would like to know how. I know that I can use a serial connection based on the RX and TX pins but I want to experiment something new.

Thank you for your time.

@Ciprian Mihai Tocaciu Welcome to Microsoft Q&A forum!

You could use any bus (SPI, I2C) for connecting both the MT3620 and MCU support.

UARTs : Azure Sphere supports universal asynchronous receiver-transmitters (UARTs) for serial communication. A UART is a type of integrated circuit that is used to send and receive data over a serial port on a computer or peripheral device. UARTs are widely used and known for their simplicity. For more details, see Use UARTs in high-level applications

SPI : Azure Sphere supports Serial Peripheral Interface (SPI) in master mode. SPI is a serial interface used for communication between peripherals and integrated circuits. SPI uses a master/subordinate model where a master device controls a set of subordinate devices. In contrast to I2C, SPI can be used with more complex higher speed peripherals. For more details, see Use SPI in high-level applications

I2C : Azure Sphere supports Inter-Integrated Circuit (I2C) in master mode. I2C is a serial bus that connects lower-speed peripherals to microcontrollers. I2C uses a multi-master/multi-subordinate model where a master device controls a set of subordinate devices. I2C is often used with peripherals that only require simple lightweight communication with a microcontroller, such as setting controls, power switches, and sensors. Form more information, see Use I2C in high-level applications and Azure Sphere – I2C examples

We have some Azure Sphere examples of talking to external MCU via UART. Please check and let us know if that helps.
