In this project, you will be converting ASCII strings received from the UART into an integer value that is passed to a provided print function. Strings will be terminated using a semicolon (;) character. Your program should be able to handle multiple strings concatenated together and treat each string ending with a ; as a separate input. When processing strings, it should detect any invalid characters within a string. Invalid characters are any characters other than 0 through 9 and ;. If an invalid character is detected the rest of the string (i.e. all characters leading up to and including the next ;) should be received by the UART, but ignored. Your program should then use the print function to output an error message and then continue processing the next string as a new string. Print Function A skeleton PLP project file is available to download on Blackboard. The PLP project includes a second ASM file titled, project_3_uart_module.asm. This file contains the print function used in this project. When called, the print function will send the value currently in register $a0 over the UART to the PLPTool simulated UART device. Register $a1 is used as an invalid character flag for the print function. If $a1 register contains a non-zero value, the print function will display an invalid character message instead of the value in register $a0. The print function is called using the following instruction: call project3_print To use the print function, your PLP program needs to initialize the stack pointer ($sp) before performing the function call (or any other operations involving the stack pointer). For this reason, the skeleton project file includes an initialization that sets the stack pointer to 0x10fffffc (the last address of RAM). This initialization only needs to be done once at the start of the program. When I input 123;32; It should print : 123 32
