| The current Mixxx JavaScript implementation for HID input packets supports following types of fields in the parser: | The current Mixxx JavaScript implementation for HID input packets supports following types of fields in the parser: | ||
| - | * One byte signed or unsigned numeric value (packing codes b and B) | + | | b / B | unsigned/signed byte | |
| - | * Two byte signed and unsgined numeric value (packing codes h and H) | + | | h / H | unsigned/signed two byte value (short) | |
| - | * Four byte signed and unsigned numeric value (packing codes i and I) | + | | i / I | unsigned/signed four byte value (int) | |
| - | * Parsing of bit mask fields from one packet of above sizes | + | |
| The bit mask fields are implemented as normal numeric value field, which has type bitvector and which has value of internal class HIDBitVector. Any bit mask size from 1 to number of bytes in the field is supported, but usually you want to address one bit for input button toggles. | The bit mask fields are implemented as normal numeric value field, which has type bitvector and which has value of internal class HIDBitVector.
