2. Programming with bootloader step 1 – Connecting PIC32MX7

For programming, microcontroller use bootloader program which is preinstaled in to MCU memory. To transfer .hex file from a PC to

MCU you need bootloader software (

mikroBootloader USB HID

) which can be downloaded from:

http://www.mikroe.com/eng/products/view/573/ multimedia-board-for-pic32mx7/

After software is downloaded unzip it to desired location and start mikroBootloader USB HID software.

10. Audio Module

Figure 10-1: Inserting

3.5mm headphones jack

The Multimedia Board features an audio module providing an interface for a microphone and stereo headphones. This module enables audio recording via a mono microphone. The microphone is connected to the system via a

3.5mm

connector CN7.

Stereo

headphones are used for audio reproduction. They are connected to the system via a 3.5mm connector CN6. For the proper use of microphone and headphones, it is necessary to write a program and load it into the microcontroller. In addition to the audio recording and reproduction, the audio module can also generate a side tone in the headphones. Volume as well as other functions of this module are controlled by the microcontroller from within the software using serial

I2C

communication. Communication between the audio module and the microcontroller is performed via the Serial

Peripheral Interface (

SPI

).
