PG4UW
Buffer data are summed word-by-word irrespective of current buffer view mode
organization. Any carry bits exceeding 32-bits are neglected. This checksum mode is
indicated by string (x16 BE) displayed after checksum value in main program window.
Term Big Endian means, the buffer checksum is calculated from words read from buffer
in Big Endian mode.
CRC-CCITT
Buffer data are summed by bytes to 16-bit word using standard CRC-CCITT algorithm
RESULT=PR (x^16 + x^12 + x^5 +1)
CRC-XMODEM
Buffer data are summed by bytes to Word using polynomial x^16 + x^15 + x^2 +1
(0x8005), init value 0
CRC-16
Buffer data are summed by bytes to sum by bytes to WORD using standard CRC-16
algorithm with polynome x^16+x^15+x^2+1 (0x8005), init value 0, and XOR out 0
CRC-32
Buffer data are summed by bytes to DWORD using standard CRC-32 algorithm with
polynome 0x04C11DB7, init value 0xFFFFFFFF, and XOR out 0xFFFFFFFF
MD5 and SHA-1
Buffer data are summed by MD5 or SHA-1 hash-sum algorithms.
The checksum modes can be set in pop-up menu by clicking on label checksum in main
program window or by menu shortcuts
Shift+Ctrl+1 for Byte sum (x8), Shift+Ctrl+2 for
Word sum Little Endian (x16) or Shift+Ctrl+3 for Word sum Big Endian (x16) etc..
Options are also available in dialog
Checksum , tab Main checksum options .
Checksum type is saved to configuration file and project file. Setting from project file has
higher precedence.
Device
Menu Device includes functions for a work with selected programmable devices - device
select, read data from device, device blank check, device program, device verify and device
erase.
Device / Select from default devices
This window allows selecting the desired type of the device from list of default devices. This
one is a cyclic buffer in which are stored recently selected devices including their device
options. This list is saved to disk by command
File / Exit and save .
If you wish display additional information about the current device, use an
<Ctrl+F1> key.
This command provides a size of device, organization, programming algorithm and a list of
programmers (including auxiliary modules) that supported this device. You can find here
package information and other general information about current device too.
