CAN

The STM32373C-EVAL evaluation board supports one channel of CAN2.0A/B complaint
CAN bus communication based on a 3.3-V CAN transceiver. High-speed mode, Standby
mode, and Slope control mode are available and can be selected by setting JP3.

HDMI CEC

Two HDMI connectors, CN1 and CN2, are available on the STM32373C-EVAL evaluation
board.
●
Connector CN1 is a HDMI sink connector with:
–
–
–
●
Connector CN2 is an HDMI source connector with:
–
–
–
–
The signals TDMS D+[0:2], TDMS_CLK+, TDMS D-[0:2], and TDMS_CLK- are connected
together on these two HDMI connectors.
CEC injector mode can be enabled (for debugging purposes only) as follows:
●
Remove resistors R120, R172, R173, R174, R175, R213, and R221.
●
Close solder bridges SB1, SB2, SB3, and SB4.
CAN-related jumpers
The CAN transceiver operates in Standby mode when JP3 is set
as shown to the right:
The CAN transceiver operates in High-speed mode when JP3 is
set as shown to the right:
This is the default setting.
The CAN transceiver operates in Slope control mode when JP3 is open.
When JP2 is fitted, the CAN terminal resistor is enabled.
Default setting: not fitted.
