Abstract

The invention discloses a Bluetooth MIDI data conversion method and circuit and a storage medium, and the method comprises the steps: reading MIDI data from a first cache, and carrying out the reading error checking and processing; when the MIDI data is successfully read, performing classification detection on the MIDI data; when the MIDI data is the first type of MIDI data, performing data analysis and code combination on the first type of MIDI data, and performing data emptying check and error reporting processing on the sending cache; when the data in the sending cache is emptied, filling the analyzed first type of MIDI data into an MIDI information structural body, and performing data integrity check and error reporting processing; and when the data in the sending cache meets the requirement of the number of the group codes, sending the data in the sending cache to a Bluetooth sending buffer area. According to the method, the MIDI data can be converted into the Bluetooth data, the data conversion efficiency is improved, the power consumption and the system delay are reduced, and corresponding error checking and processing are performed on a plurality of steps in the conversion process, so that automatic error correction and error code processing are realized.

Description

technical field [0001] The invention relates to the technical field of audio processing, in particular to a Bluetooth MIDI data conversion method, circuit and storage medium. Background technique [0002] Traditional electronic musical instruments generally only have MIDI (Musical Instrument Digital Interface, musical instrument digital interface) plugs or USB-MIDI plugs, and electronic musical instruments themselves have limited resources, and mobile devices such as mobile phones or tablet computers can obtain a large number of music resources through the network, so It is necessary to connect traditional electronic musical instruments and mobile devices. The traditional connection method is to use data cables to connect electronic musical instruments and mobile terminal devices, which is inconvenient to use when connecting. There are some Bluetooth MIDI conversion devices on the market at present. Since Bluetooth technology itself is widely used in some mobile devices, con...
