Development and debug support
The two debug connectors available on the STEVAL-IHM022V1 demonstration board are:
●
CON6 - a standard 20-pin JTAG interface connector that is compliant with ARM7 and
ARM9 debug tools.
●
CON5 - a SAMTEC 20-pin connector (code FTR-110-01-S-D) for both SWD and trace
that is compliant with ARM CoreSight debug tools.

Display and input devices
The 240 x 320 TFT color LCD and 4 general-purpose LEDs (D1, D3, D3, D4) are available
as display devices. A 4-direction joystick with selection key (U1), a general-purpose button
(SW3), a wakeup button (SW2) and a tamper detection button (SW1) are available as input
devices.
Jumper JMP3 should be kept open to enable wakeup button SW2, which shares the same
I/O with motor control connectors MC main and MC sub2.
