Hello everyone,

Can anyone tell me how 1347957792 is derived from “PX4” in this example?

Thanks

OK I get it now. It’s an int32, BCD, ASCII/UTF-8 encoding so "PX4 " ----> P=01010000 X=01011000 4=00110100 ’ '=00100000

[DEC]1347957792 = [HEX]0x50583420 = [BIN/BCD]01010000 01011000 00110100 00100000 = "PX4 "
