Hardware
1. I don’t have a Type-C connector on my PC. Can I still connect and use this kit?
Yes. To evaluate PSoC™ 6 MCU features, any PC with USB 2.0 connectivity is sufficient.
2. How does CY8CKIT-062-WIFI-BT handle voltage connection when multiple power sources are
plugged in?
There are five options to power the baseboard: Type-C USB connector (J10), external DC supply
via VIN connector (J9/ J1), debug and trace header (J12, VTARG_IN), program and debug
header (J11). Type-C and VIN take priority over other supply options. These inputs are ORed
using a diode, and the higher voltage between the two take precedence. The output of the ORing
diode is given to a buck-boost regulator (
U30
) that generates a constant 5.2 V. This output is
ORed with the ETM supply (J12), which is typically 5 V. For most practical applications, the
output from the 5.2-V regulator takes priority and the same is given as an input to the voltage
regulator (U10). The output of the buck regulator (U30) is ORed with the supply voltage from the
program and debug header (J11); the higher voltage takes precedence. See
for more details on voltage input and output scenarios.
3. How can I access smart I/O and other GPIOs connected to the on-board peripherals?
The smart I/O (Port 8 and Port 9.3) and GPIO connected to the on-board peripherals are
multiplexed with PSoC™ 6 MCU I/O headers (
J2
and
J20
). By default, some of these I/Os are
connected to the on-board peripherals using series resistors. These resistors can be changed to
route these I/Os to headers. See
for the list of resistors that needs to be
changed.
4. Why does the red LED (LED5) light up when switch
SW7
is set to the super capacitor position?
This behavior is observed if the super capacitor is charged below 1.5 V. The I/Os referring to this
domain will leak current; in this case, P0[3]. The VBACKUP feature needs to be enabled in the
device before switching
SW7
to the super capacitor position. See the device TRM or datasheet
for options to enable super capacitor charging.
5. What are the selection switches on the baseboard used for?
gives details on all two selection switches.
6. What is the on-board jumper used for?
The jumper J8 can be used to measure the current of the PSoC™ 6 MCU without the need to
desolder any component from the board. An ammeter can be connected across this jumper to
measure the current consumed by the PSoC™ 6 MCU. Remove the jumper on J8, connect an
ammeter (positive terminal of ammeter to Pin 2), and power the kit though USB connector J10.
