The Advanced Audio Transfer Model (A2DP) created by the Bluetooth Special Interest Group (SIG) facilitates convenient wireless stereo audio applications such as home and car smartphone audio docks, wireless speakers, A/V receivers and all functions A small audio system, etc. Support for Bluetooth audio is a common requirement for today's smartphone docking solutions. Consumers use mobile phones as a source of music and use the phone as a remote control for selecting tracks throughout the room. Faced with the challenges of RF design, software development and certification, developers need a mature, convenient and complete development kit that is ready to use. Due to the diversity of market needs, developers also need the flexibility to customize their own development platforms to meet their target markets.
The PIC32 Bluetooth Audio Development Kit comes with an audio stream demo code that delivers up to 24-bit 192 kHz audio and has been tested on over 100 different Bluetooth audio devices, covering 18 different manufacturers. The Bluetooth hardware module and Bluetooth A2DP audio software have been certified by Bluetooth.org, saving developers a large certification fee. The modular design helps developers replace the daughter boards included in the toolkit (one for audio and one for Bluetooth) and create their own customized versions with their preferred audio and wireless solutions. The kit also supports USB host and device connectivity, Apple® device authentication module interface, a 2-inch color LED, five universal push button switches, five LEDs, and a plug-in module interface for PIC32 microcontroller upgrades. The PIC32MX450F256 MCU runs at 80 MHz and has 256 KB of flash and 64 KB of RAM. The toolkit is an excellent universal development tool with its extensive feature set and flexibility.
Sumit Mitra, vice president of Microchip's 32-bit microcontrollers, said: "Microchip's new Bluetooth Audio Development Kit is an ideal solution for developers who want to add high-quality wireless audio to their designs. The development kit includes a Interfaces for iPod® and iPhone® products that can be extended to support these popular devices."
Development support
Microchip also released the required Bluetooth library for the kit to support multiple audio and data configurations, as well as USB digital audio. These include the Bluetooth Serial Port Protocol (SPP) (available now at http://), Bluetooth Audio Suite 1 (A2DP supporting standard SBC codecs) and Bluetooth Audio Suite 2 (supporting SBC) + A2DP for AAC codec).
Supply
The PIC32 Bluetooth Audio Development Kit (part number DV320032), Bluetooth Audio Kit 1 (part number SW320014-1) and Bluetooth Audio Kit 2 (part number SW320014-2) are now available for purchase.
Type Rechargeable Vape Pen Disposable ecig have a completely enclosed design, reducing the need for charging and replacing cartridges. The no-charge design also reduces the occurrence of faults. It is understood that with rechargeable e-cigarettes, each cartridge needs to be charged at least once and the battery efficiency is extremely low, while the design of disposable ecig can solve this problem very well.
