2.6 EEPROM
A 64 Kbit EEPROM is connected to the I2C1 bus of the STM32F417IGH6.
2.7 CAN
The STM3241G-EVAL evaluation board has two channels of CAN2.0A/B compliant CAN
bus communication based on a 3.3 V CAN transceiver on the DB9 connector (CN10). The
two CAN buses can be disconnected by jumpers from relevant STM32F417IGH6 I/Os which
are shared with FSMC and USB-OTG HS. Jumpers JP3 and JP10 must be refitted to
enable CAN1 or CAN2 as listed in
Table 6
.
High-speed, Standby and Slope Control modes are available and can be selected by setting
jumper JP7.
