Enable PC10(pin 51) of STM32F103RBT6 to control CAN driver modes.
Log. 1 of PC10 disable CAN driver. Log. 0 of PC10enable CAN driver with
high speed mode.
Default state - open
RTS_E Connect PA1/USART2_RTS pin to COM port driver(ST3232).
USART2_RTS function of PA1 is used for handshake mode of COM port.
Default state - open
CTS_E Connect PA0-WKUP/USART2_CTS pin to COM port
driver(ST3232). USART2_CTS function of PA1 is used for
handshake mode of COM port. By default is used Wake Up
function(PA is permanent tied to Wake Up button).
Default state – open
CP_E Card Present Enable – Allow PC7(pin 38) to detect Multi Media
Card present in socket. Log. 1 of PC7 – MMC present. Log.0 of
PC7 – Card absent.
Default state closed (shorten)
WP_E Write Protect Enable – Allow PC6(pin 37) to detect write
protected state of Multi Media Card. Log. 1 of PC6 – MMC no
write protected . Log.0 of PC7 – MMC is write protected.
Default state closed (shorten)
3.3V_MCU_E Connect 3.3V regulated voltage to STM32F103RBT6
power pins. 3.3V_MCU_E jumper is used if you need to
measure current consumption of the microcontroller.
