Compute the length of a message after it is encoded.

#Parameters
  • decoded_length The length, in bytes, of the message to encode.
#Returns

The length, in bytes, of the message after encodeing.

#public uint16_t sysex_decoded_length(uint16_t encoded_length) {#group__sysex__tools_1ga121fc227d3acc1c0ea08c9a5c26fa3b0}

Compute the length of a message after it is decoded.

#Parameters
  • encoded_length The length, in bytes, of the encoded message.
#Returns

The length, in bytes, of the message after it is decoded.

#public uint16_t sysex_encode(uint8_t * encoded,const uint8_t * source,uint16_t length) {#group__sysex__tools_1ga54d77f8d32f92a6f329daefa2b314742}

Encode data so that it can be transmitted safely in a sysex message.

#Parameters
  • encoded The output data buffer, must be at least sysex_encoded_length(length) bytes long.

  • source The input buffer of data to be encoded.

  • length The number of bytes from the input buffer to encode.

#Returns

number of bytes encoded.

Decode encoded data.

#Parameters
  • decoded The output data buffer, must be at least sysex_decoded_length(length) bytes long.

  • source The input buffer of data to be decoded.

  • length The number of bytes from the input buffer to decode.

#Returns

number of bytes decoded.
