Newbie help! About MSP430G2553 control RC522 RF card reader/writer program problem [Copy link]

      As the title says, I want to use MSP430G2553 to control the RC522 card reader to read and write cards. Functions to be implemented: 2553 performs AD conversion on the input voltage (single-channel multiple sampling, timer interrupt, AD conversion is started when the P1.3 port queries the button is pressed), and the obtained value is automatically stored in ADC10MEM. I assign ADC10MEM to array data1, and then write the data to the card through the pointer pointing to data1 in the card reading and writing program, and then read the data out through the card reading program, and it has been confirmed that it works normally. My design idea is to divide the entire program into two parts: the AD sampling part and the RC522 card reading and writing part. When running alone, the AD conversion part can complete the AD conversion normally, and the RC522 card reading and writing program can also complete the card reading and writing normally; however, I have been making mistakes in the process of transferring the value of ADC10MEM to RC522, and I am not familiar with the use of pointers~~~ Attached is the program, please help me~~~ #include
