Hardware
14. What type of shield from Infineon is compatible with this baseboard?
Any shield compatible with Arduino Uno that supports 3.3-V operation is compatible with this
pioneer board. The following Infineon shields are pin-compatible with this board:
a. CY3280-MBR3
b. CY8CKIT-022
c. CY8CKIT-024
d. CY8CKIT-026
e. CY8CKIT-040
f. CY8CKIT-046
g. CY8CKIT-048
15. Why am I not able to program PSoC™ 6 MCU using MiniProg4 at 1.8 V?
The “program/debug overvoltage protection” circuit shown in
program and debug header (J11) on page 47
does not allow programming of the device at 1.8 V
through MiniProg4. If you want to program the PSoC™ 6 MCU using MiniProg4 at the 1.8-V
condition, make sure you are populating the 0-ohm resistor at R196 on the board. This resistor
will bypass the protection circuit and will allow programming of the device at 1.8 V. Make sure
you are not populating this resistor at any other voltage of operation.
16. How can SW2 be used for PMIC wakeup?
SW2 is connected to the PMIC_Wakeup_In pin (P0.4) of the PSoC™ 6 MCU. A logic HIGH input
at the PMIC_Wakeup_In pin can wake up the system and enable the PMIC. See the “Backup”
chapter in
PSoC™ 6 MCU architecture technical reference manual
for more details of this
feature.
SW2 should be externally pulled down to ground to use PMIC control. Moreover, when the
switch is pressed, the active HIGH logic should push P0.4 to the VBACKUP supply. However,
the kit is configured by default to use active LOW logic as described in
In addition, in REV04 or later version of the kit, the active HIGH logic for SW2 pushes P0.4 to
VBACKUP. Therefore, the following re-works on the kit are required to use the PMIC control
feature:
■
Remove R65 and populate the 0-Ω resistor R66.
■
Remove R67 and populate a 10-kΩ resistor at R68.
