Purchase your STM32 kit this week between 8:30 and 4:30 Monday through Friday in the Software Engineering office.
The cost is $28.71 (total including sales tax). Tiger Bucks is the only form of payment accepted.

UART Cross Connect Interrupt 1 Not graded
Due Monday April 15 11:59 PM (HW1) Network Activities
Due Wednesday April 17 11:59 PM (HW2) Network Activities
Due April 22 at 11:59 PM UART Cross Connect Interrupt 2
Due April 29 by 3:50 PM Use the unit test framework to create two CRC unit tests (one match and one mismatch) using the Barr Group crc.zip library functions

Use this updated zip file instead as your starting file. We will go through this in class on Monday. We will help you finish in class.
Reference: The Barr Group Checksums and CRCs
Unit test 1 definition: Call append_crc function with the "1234". Pass the updated char array to verify_crc function and confirm it returns true.
Unit test 2 definition: Call append_crc function with the "4321". Modify the updated char array to start with '5' instead of '4'. Pass modified version of the updated string to verify_crc function and confirm it returns false.
void append_crc( unsigned char *data ) where char *data points to a char array with a string and at least 4 bytes after the end of string marker in that array.
uint8_t verify_crc( char *data ) where char *data points to a char array with 4 bytes of crc after the strings '\0' end of string marker. This is a modified version of our standard string marker. This function returns true if CRC is correct, false otherwise.
Use the crcSlow() function in the provided crc.zip file to calculate your crc.
To do the copy of the crc value to the char array I suggest using memcpy to copy the four bytes to a pointer that points to the char (byte) after the '\0' end of string marker.

In class C language practicum (50 minutes) on Wednesday March 6th.
Section 01 exam is at 8:10 AM to 9:00 AM
Section 02 exam is at 2:10 PM to 3:00 PM
The first 10 minutes of class will be an introduction to the next activity. That activity will be due Tuesday March 19th at 11:59 PM.

Exam begins at 10 minutes after the start of class.
Practicum exam remains at 20% as stated before that exam.
Closed book with one 8.5x11 inch double sided reference sheet written exam (50 minutes) on Wednesday April 3rd.
This is a BONUS exam. Full credit on this exam can give you up to 5 points added to your course grade.
A better grade on this exam will replace a low practicum exam grade. A reduced bonus may apply in some cases.
Review topics:

C Language bitwise operations including an 8 bit hardware register using | and & bitwise operators.
8 bit signed and unsigned integers.
Two's complement for 8 bit values.
Reasonable proficiency with hexadecimal is expected. I will provide a hexadecimal chart.
Code quality question on some provided C code.
Non-blocking versus blocking operation.

Final exam (written closed book with reference sheet) location is the LOW-3215 auditorium in the Max Lowenthal Hall
