Kit operation
The TFT display shield has the following peripherals:
1.
2.4-inch TFT display:
This is a
module with 240 × 320 pixel
resolution and uses a
Sitronix ST7789 display controller
. This display module is configured for an
8-bit parallel pinout connection (8080-Series) to interface with the PSoC™ 6 device on the
baseboard.
2.
Inertial measurement unit (U1):
This inertial measurement unit (IMU) is a three-axis
acceleration and three-axis gyroscopic motion sensor that can be used to count steps to emulate
a pedometer or similar application.
3.
Ambient light sensor (Q1):
This is a high photosensitive NPN phototransistor IC that can be
used to detect intensity of ambient light.
4.
PDM microphone (U2):
This microphone converts voice inputs to pulse-density modulated
(PDM) digital signals.
5.
I/O header compatible with Arduino (J2, J3, and J4):
These headers interface with the
PSoC™ 6 MCU GPIOs on the baseboard.
6.
Power header compatible with Arduino (J1):
This header receives power from header J1 on
the board.
7.
Voltage regulator - 1.8 V (U4):
An LDO that converts 3.3 V to 1.8 V for the digital supply of the
audio codec.
8.
TFT display connector (J5):
This connector is used to connect the TFT display to the circuits on
the TFT display shield.
9.
Audio codec (U3)
: This is a low power consumption, 32-bit stereo codec with speaker amplifiers.
The left channel and right channel amplifier output pins of the device are connected to the on-
board audio jack.
10.
Audio jack (J6)
: The on-board audio jack provides a provision of connecting both AHJ and
OMTP headphones. The headset standard can be set by an on-board switch SW1.
11.
Audio jack selection switch (SW1)
: This on-board selection switch can set the headphone
type either to AHJ and OMTP standard connected to the audio jack.
