can someone help?
hi! is this a live project?
Apologies, I missed this one. Currently, there are no built-in methods to read a 33-bit field. A workaround would be to combine a 32-bit field and a 1-bit field manually.
Thanks @keichi would you show me an example how to do it? Thanks
Here's an example:
const Parser = require("binary-parser").Parser;
const parser = new Parser()
.bit32("a")
.bit1("b");
const buf = Buffer.from("aaaaaaaa80", "hex");
const res = parser.parse(buf)
console.log((BigInt(res.a) << BigInt(1) | BigInt(res.b)).toString(16)); // -> 155555555
Note that you need to use BigInt
since bitwise operations on Number
automatically convert the operands and results to 32-bit integers.
I will close this issue for now. Please reopen if needed.
Hello all, Can someone guide me on how to read 33 bits? The bitX() is limited to 32 Thanks!
