2.5 Audio
The STM3210E-EVAL evaluation board supports stereo audio play because it provides an
audio DAC AK4343 connected to both I
2
S port and two channels of DAC of microcontroller
STM32F103ZGT6. Either external slave mode or PLL slave mode (reference clock BICK or
LRCK) of audio DAC can be used by setting the jumper JP18.
The I2S_MCK is multiplexed with smartcard and motor control, and can be enabled by
setting the jumper JP15. Refer to
Section 2.9: Motor control
for details. Audio DAC AK4343
is in power-down mode when PDN pin is pulled-down by PG11.
2.6 Serial
Flash
A 64 or 128 Mbit serial Flash connected to SPI1 of STM32F103ZGT6 serial Flash chip
select is managed by IO-pin PB2. The SPI1_MISO is multiplexed with motor control, it can
be enabled by setting the jumper JP3. Refer to
Section 2.9: Motor control
for details.
2.7 CAN
The STM3210E-EVAL evaluation board supports CAN2.0A/B compliant CAN bus
communication based on 3.3 V CAN transceiver. High-speed mode, standby mode and
slope control mode are available and can be selected by setting JP8.
