- Hi! Can you please help me with the code for this? It's written using CubeMX and IAR for the STM32F429ZI microcontroller board. Develop a syntactically correct C program for the asynchronous serial communicationsprotocol as follows. Your program should set up the USART1 Module of the STM32F4microcontroller to communicate (transmit and receive) at the rate of approx. 50000 Baud.You should choose suitable clock rates for this problem. The frame should consist of astart bit, seven data bits, even parity bit, and one stop bit. It is up to you to decidewhether you want to work with interrupts or with the polling method.The program first waits for a syn character (syn=0x16) but will only accept it if noreceive error flags (FE, PE, or ORE) are set. If any error flags are set the program shallrespond by sending a nak character (nak=0x15), it will send an ack character(ack=0x06), otherwise. The process repeats until a received syn character is accepted.However, the program should keep a syn…After interfacing an MCP4822 DAC to an ATTiny85, write a program so that it produces 2.5V on the DACS pin 8. Comment each line of code. Once you connect two active high pushbuttons and interface them to the ATTiny85, write a program that when pressing one button, it decreases the DAC's voltage by 0.1V. The program should also have it to when the other button is pushed, the DAC's voltage should increase by 0.1V.
