Question

help me, how can wright the code using ( atmel 7 )

( GCC C ASF Board Project ) C/C++

Equipment and Materials SAMD21 or SAMW25 Xplained Pro 1) 2) USB cable 3) PC ELVIS II board 4) Program UART Write a program that uses the default UART interface of the SAMD21 microcontroller to communicate with over the the UART of the EDBG microcontroller. The EDBG chip will then convert the serial data and send this USB to the PC. This provides which is obviously a useful function. an interface for sending and receiving data between your SAMD21 and a PC Write C code that sends the string "Enter a temperature value" across the serial connection when the SWO button on the XPRO board is pressed. Read the value sent back when a user enters a two-digit number into the serial terminal which should be in the form of two numbers (00-99). Echo back this value to the serial port in the form, "You enter the value XX". Each time the user button is pressed, the string should be sent and you should wait until a value is entered. You will need to specify the typical attributes of the connection such as baud rate and pin connections. Procedure UART 1) Load your program to the SAMD21 XPRO. Connect your board to the PC using a USB cable. 2) 3) Find the COM port associated with your board. You can do this by going to the device manager and looking at the attached COM devices, or you can open Command Prompt and type "mode". This will list all attached COM port devices. If your board is the only one, it will be easy to determine which one is yours. If not, unplug your device and type "mode" again to see which port is no longer listed 4) Open putty. And enter the appropriate settings for serial communication. Open the connection. 5) Press the user button and wait for the prompt. Then enter a two-digit number. 6) Check to see if the value is sent back.
