Decode CAN DBC data
npm install can-dbc-decode
const decode = require('can-dbc-decode')
const input = {
rawData: '46220000FFFFFFFF',
start: 0,
size: 32,
factor: 0.05,
offset: 0,
precision: 5,
endianness: 0
}
decode(input)
// => 438.7
Assuming the rawData in HEX is 0x0000047900000033, grouped HEX data is 00 00 04 79 00 00 00 33
In Motorola(big endian) format, The bit map of this rawData is
If have below input:
start: 60,
size: 4,
factor: 1,
offset: 0,
precision: 5,
endianness: 1
It will decode the data in red frame
String, the input Hex data without 0x, rawData should be no signed.
* required
Integer, the start bit position.
* required
Integer, the length of bits.
* required
Number, factor of the returned data.
default: 1
Number, offset of the returned data.
default: 0
Interger, Max precesion of returned data.
default: undifined // no limitation
0 or 1, 0 - Intel(little endian) and 1 - Motorola(big endian).
default: 0 - Intel(little endian)
