Hex File Crc 16 Calculator Checksum
Per Westermark 'Can you please give more details. I am not able to get the below mentioned point' 10 + (-10) = 0. Or when doing unsigned computations without caring for overflow in a computer: 0xffff + 0x0001 = 0x0000 So if the 16-bitchecksum of all flash bytes except the last two in your flash ends up as 0x83f0 then you can decide to store 0x7c10 in the last two bytes of the flash So when the program does a 16-bit checksum of all the flash, it ends up with a sum that is zero 0x83f0 + 0x7c10 = 0x10000 which after 16-bit overflow means 0x0000 How to figure out the value 0x7c10? That's the 16-bit unsigned result of 0-0x83f0. Just note one thing - while you may send a hex file to your processor, your processor will not store any hex file. The processor stores the binary data that is represented in the hex file. A program in the PC - or a bootloader in the processor - will decode the hex file to extract this binary data.
Hi, I need advice on how to calculate checksum in a line of intel hex file format. Basically I understand how it need to be calculate but to write it in VB code is.

Next thing - the processor will normally store the value 0xff in all bytes that does not get any content from the hex file. And these 0xff bytes will also be part of the checksum that the program computes. So the PC side must remember this when it computes a checksum before programming the processor.
Check Sum/Hash Algorithms The Check Sum tool can be used to apply a number of Check Sum or Hash Algorithms to the current file. Run the Check Sum tool by clicking the ' Tools Check Sum.'
