63. ystems EVB90609 Evaluation Board 12 3 Checksum The aim of a checksum is to detect errors This detection technique enables the receiver of a message transmitted through a noisy error introducing channel to determine whether the message has been corrupted or not To do this the transmitter constructs a value called a checksum that is a function of the message and appends it to the message The receiver can then use the same function to calculate the checksum of the received message and compare it with the appended checksum to see if the message was correctly received Description Here s a simple algorithm written in a pseudo high level and C language Calculating a checksum is just adding together all the bytes in the command getting the low byte inverting it and adding 1 After that the checksum will be appended to the command lt CS gt invert LlowByte xbyte 1 Example C command C669F2FCC checksum CC Pseudo high level code 1 Ox66 0x9F 0x2F 0x0134 2 LowByte 0x0134 0x34 3 Invert Ox34 OxCB 4 OxCB 0x01 CC And how result we have lt CS gt OxCC C code BYTE CS 0x66 0x9F 0x2F 0x01 EVB90609 Page 79 of 88 May 22 Rev 1 01 way User Manual Microelectronic Integrated Systems EVB90609 Evaluation Board 13 Schematic S POWER EST E 0O OO o 51 O O o e CS CS 5 n Wz oll lool o eoooooceo 00000000 CVESOBOS w 1 3 USB M elex 2000000000
