1.9 USB
The STEVAL-IHM022V1 demonstration board supports USB 2.0-compliant full-speed
communication via a USB type B connector (CON11). The board can be powered by this
USB connection at 5 V DC with a 500 mA current limit. USB disconnection simulation can
be implemented by disconnecting the 1.5 k pull-up resistor from the USB+ line. The USB
disconnection simulation feature is enabled by setting JMP1.
JP4
A jumper on JP4 should be fitted to enable filtering when an
analog signal is present on pin 31 of CON8 (e.g. a signal
generated by a tachometer). It should be not fitted if a signal
from an encoder is used.
Default setting: not fitted
JP6
A jumper on JP6 should be fitted to enable filtering when an
analog signal is present on pin 31 of CON9 (e.g. a signal
generated by a tachometer). It should be not fitted if a signal
from an encoder is used.
Default setting: not fitted
JP7
A jumper on JP7 should be fitted to enable filtering when an
analog signal is present on pin 31 of CON10 (e.g. a signal
generated by a tachometer). It should be not fitted if a signal
from an encoder is used.
Default setting: not fitted
J1
J1 swaps timer 8 channel 3 PWM outputs between pin 11 (MC
WH) and pin 13 (MC WL) of MC sub1 connector.
Default setting: as shown.
J2
J2 swaps MC sub1 bus voltage and MC sub1 currentB analog
signals between pin 44 (ADC12_IN14) and pin 20 (ADC3_IN6)
of the STM32 MCU.
Default setting: as shown.
