mikromedia 7 HMI Capacitive board is designed as a complete
solution for the rapid development of multimedia and GUI-centric
applications. By featuring a 7” capacitive touch screen with a multi-
touch panel, driven by the powerful graphics controller with advanced
features, it represents a perfect solution for any type of Human
Machine Interfaces (HMIs).
At its core, there is a powerful MKV58F1M0VLL24 microcontroller
(referred to as “host MCU” in the following text), produced by NXP, which
provides sufficient processing power for the most demanding tasks,
ensuring fluid graphical performance and glitch-free audio reproduction.
The usability of mikromedia 7 HMI does not end with its ability to
accelerate the prototyping and application development stages: it
is designed as the complete solution which can be implemented
directly into any project, with no additional hardware modifications
required. TFT display is equiped with a metal frame, and four corner
mounting holes that enable simple installation in various kinds of
industrial appliances. mikromedia 7 HMI is ideal for smart home
solutions, as well as wall panel, security and automotive systems,
factory automation, process control, measurement, diagnostics and
many more. A nice casing is all that you need to turn the mikromedia
7 HMI CAPACITIVE board into a fully functional design.

MCUs FEATURES
Back view
The host MCU can be programmed and debugged over the JTAG/SWD
compatible 2x5 pin header (1), labeled as PROG/DEBUG. This header
allows an external programmer (e.g. CODEGRIP or mikroProg) to be used.
The board is equipped with the Reset button (2), which is located on the
front side of the board. It is used to generate a LOW logic level on the
microcontroller reset pin.

CAPACITIVE DISPLAY
2. Capacitive display
A high-quality 7” TFT true-color display with a capacitive touch
panel is the most distinctive feature of the mikromedia 7 HMI.
The display has a resolution of 800 by 480 pixels, and it can
display up to 16.7M of colors (24-bit color depth). The display
of mikromedia 7 HMI features a reasonably high contrast ratio
of 500:1, and brightness intensity of 420 Cd/m2, thanks to a
matrix of 9 x 3 high-brightness LEDs (27 in total) that are used
for backlighting.
The display module is controlled by the FT813 graphics driver
IC from FTDI. This is a powerful graphics controller targeted
at embedded applications to generate high-quality Human
Machine Interfaces (HMIs). It also includes some advanced
features such as the embedded video engine, enhanced sketch
processing, built-in synthesizer, and more.
The capacitive multi-touch panel, based on the FT5426 CTP
controller, allows the development of interactive applications,
offering a touch-driven control interface. The touch panel
controller uses the I2C interface for the communication with
the host controller. This advanced multi-touch panel controller
supports gestures, including zoom and swipe in all four
directions.
Equipped with high-quality 7” display (1) and the multi-touch
controller that supports gestures, mikromedia 7 HMI represents
a very powerful hardware environment for building various GUI-
centric Human Machine Interface (HMI) applications.

3.1 microSD card slot 3.2 External flash storage
The microSD card slot (1) allows storing large amounts of data externally,
on a microSD memory card. It uses the Serial Peripheral Interface (SPI) for
communication with the MCU. The microSD card detection circuit is also
provided on the board. The microSD card is the smallest SD Card version,
measuring only 5 x 11 mm. Despite its small size, it allows tremendous
amounts of data to be stored on it. In order to read and write to the SD
Card, a proper software/firmware running on the host MCU is required.
mikromedia 7 HMI features EN25Q80B Serial Flash Memory [2] which uses
SPI communication interface and has 8 Mbits of available memory with
enhanced write protection mechanisms. The memory can be programmed
1 to 256 bytes at a time, using the Page Program instruction.
The device can sustain a minimum of 100K program/erase cycles on each
sector or block. It also uses the SPI interface for the communication with
the MCU.

4. Connectivity
mikromedia 7 HMI offers a USB-UART connectivity option.
Besides that, it also offers two standardized mikroBUS™
Shuttle connectors. It is a considerable upgrade for the
system, as it allows interfacing with the huge base of Click
boards™.
4.1 USB-UART
UART (Universal Asynchronous Receiver/Transmitter) interface is one of the
most common interfaces for data exchange between the MCU and other
external devices. mikromedia HMI 7 board offers the UART connectivity
over the USB-C connector (1) by utilizing the FT230XQ, a popular USB-
UART bridge IC, produced by FTDI Chip. This IC contains the complete USB
stack necessary for the interface bridging between the UART peripheral of
the MCU and the USB interface of the PC. FT230XQ drivers are available for
download from the mikromedia HMI 7 product web page, as well as from
the official FTDI drivers download web page.

4.2 mikroBUS™shuttle connectors
mikromedia 7 HMI CAPACITIVE development board uses the mikroBUS™
Shuttle connector, a brand new addition to the mikroBUS™standard in the
form of a 2x8 pin IDC header with 1.27mm (50mil) pitch. Unlike mikroBUS™
sockets, mikroBUS™Shuttle connectors take up much less space, allowing
them to be used in cases where more compact design is required. There
are two mikroBUS™Shuttle connectors (1) on the development board,
labeled from MB1 to MB2.
Typically, a mikroBUS™Shuttle connector can be used in combination with
mikroBUS™Shuttle extension board but is not limited to it.
mikroBUS™Shuttle extension board (2) is an add-on board equipped
with the conventional mikroBUS™socket and four mounting holes. It
can be connected to the mikroBUS™Shuttle connector by a flat cable.
This ensures compatibility with the huge base of Click boards™. Using
mikroBUS™ Shuttles also provides a number of additional benefits:
∫When using flat cables, the position of mikroBUS™Shuttle is not fixed
∫mikroBUS™Shuttle extension boards contain additional mounting holes
for permanent installation
∫An arbitrary length of flat cables may be used (depending on the
particular use cases)
∫Connectivity can be additionally expanded, by cascading these
connectors using Shuttle Click

5. Audio Speaker
To round-up its multimedia concept, mikromedia HMI 7
features an audio speaker paired with a Class-AB audio
amplifier.
The TPA6203A1 is a 1.25-W mono fully differential amplifier
designed to drive a speaker with at least 8Ωimpedance.
Features like 85-dB PSRR from 90 Hz to 5 kHz and improved
RF-rectification immunity, make the TPA6203A1 ideal for
multimedia applications.

6. Haptic feedback
motor
Haptic feedback motor features a compact size Eccentric Rotating Mass
(ERM) motor (1). This type of motor is often used for haptic feedback
on many small handheld devices, such as the cellphones, pagers, RFID
scanners and similar devices. This motor contains a small eccentric weight
on its rotor, so while rotating it also produces vibration effect. This kind of
motors is sometimes referred to as coin motors, due to its shape.
This is an ideal solution for adding a simple, one pin driven haptic feedback
on any design.
