Appendix F: Hardware Setup for Application Demo in Host MCU Mode
Note:
The host MCU (on-board PIC32 MCU) is connected to the BM83 module over UART. The host MCU is
controlling the BM83 module and driving the I2S audio out from the BM83 to an STA369BW Audio Daughter Board.
Perform the following hardware changes for the Host MCU mode application demo:
Note:
To locate these switches, jumpers, and headers on the BM83 EVB, refer to
1.
Mount a jumper on the pin2 (3V3_IO) and pin3 (VDDIO) of JP305.
2.
Set the SW200 switch to 5V_DC position to enable the 5V supply to ADAP_IN.
3.
Mount a jumper on the 3V3_GEN pin and 3V3_PIC pin of the JP400 to enable 3.3V to PIC.
4.
Jumper settings on J402 and J403 to enable BM83 module to control DSP (audio codec):
4.1.

4.6.
Mount a jumper on pin6 of J402 and J403.
4.7.
Open pin7 of J402 and J403.
5.

5.5.
Mount a jumper on pin5 of J700 and J701.
5.6.
Mount a jumper on pin6 of J700 and J701.
5.7.
Mount a jumper on pin6 of J700 and J701.
5.8.
Open pin8 of J700 and J701.
6.
Mount a jumper on pin2 and pin3 of JP201.
7.
Set SW400 switches as follows:
