2 Getting started

Figure 1: Koala EVM PCB Layout

1. The Koala EVM must be supplied with 5v power. Power can be supplied with a 5v DC adapter via CN20

screw terminal or CN18 barrel connector, or via USB by connecting CN11 mini USB port to a standard

COM port of the PC.

2. To program the board:

i. connect CN11 mini USB port to a PC,

ii. configure the tool chain to use ST-LINK JTAG, and

iii. connect appropriate jumpers from ST-LINK to programming target (main MCU or WMI module).

3. Use the provided demo applications for test and development.

4. Connect any additional project accessories (LCD, camera, wireless modules, USB or Ethernet cables)

5. Download and run the software applications using the preferred tool-chain.

3 Configuring the Koala EVM Hardware

The Koala EVM hardware is configured by setting on board jumpers.

3.1 CAN Bus Termination

For high speed or long distance transmission, it is recommended to enable the CAN termination resistor. This is

done by shorting J2 pins.

Figure 3: Jumpers shorting J2 pins –enables CAN termination resistor

3.2 USART2 / FSMC (LCD) Selection

A UART peripheral and the LCD controller share a data line on the Koala EVM, and the required function must be

selected accordingly.

If any of the WMI modules require access to USART2, then CN21 pins 1-2 must be connected.

Figure 4: Jumpers shorting CN21 pins 1-2 –enables USART2

To enable LCD functionality, CN21 pins 2-3 must be connected.

Figure 5: Jumpers shorting CN21 pins 2-3 –enables LCD functionality

4 ST-LINK Configuration: Programming / Debugging the

Koala EVM

The embedded ST-LINK can be used to program the on board microcontroller and debug applications. Configure

the jumpers as shown below to enable ST-LINK program/debug.

program/debug

5 Wireless Module Interfaces

5.1 Connecting Modules

The Koala EVM features a 100 pin COM8 socket for connecting Wi-Fi / Bluetooth modules. The connector is

marked “COM8” and is notched. Position of the notch must be observed to avoid damaging the module.

Figure 7: COM8 connector. The notch is located on the bottom-right corner of the connector.

Clarinox WMI modules may also be connected to the Koala EVM with the dedicated WMI connectors. The WMI

module is to be inserted in both connectors, observing the notches for correct placement of the module.

Figure 8: WMI connector

5.2 Hardware interface

When connecting a module to the COM8 connector, the following methods are to be used for interfacing with the

STM32F407IGT6/STM32F429IIT6 Microcontroller.

WLAN communications are through SDIO interface, as shown in the following diagram.

Quick Start Manual

Page 9

Figure 9: Wi-Fi communication hardware layout and signals

Bluetooth HCI is connected to USART6 of the microcontroller. Cross connection of TX/RX and RTS/CTS lines

must be observed according to the following diagram.

Figure 10: Bluetooth communications hardware layout and signals

Bluetooth and Wi-Fi both have their own select/enable line. An interrupt line is also provided for Wi-Fi.

The Koala EVM board provides level translation and slow clock for interfacing to the attached COM8 module.

Output to ClarinoxDebugger is provided through USART2 of the microcontroller. ClarinoxDebugger is a powerful

GUI tool for remotely debugging ClarinoxSoftFrame-based applications. For more information on the debugger,

refer to the ClarinoxDebugger user manual.

6 Brief Description of Key Peripherals

Power supply

The Koala EVM is powered by USB or external supply (5v). The board features both a screw terminal (CN20) and

barrel connector (CN18) for external power supply of 5v to supply on board regulators and USB-OTG VBUS.

Regulators provide 3.3v for MCU and peripherals and 1.8v for wireless module.

5v and 3.3v are supplied to WMI connector.

USB

The Koala EVM supports USB-OTG HS. The USB micro connector (CN2) allows the user to connect to a host or

peripheral device in full speed operation without a PC.

A USB mini connector (CN9) is also featured which enables direct communication with a PC by converting USB to

serial (USART).

Camera interface

The Koala EVM features a digital camera interface (DCMI connector) to acquire images from a camera accessory.

Single frame or continuous capture is supported in an 8 to 12 bit parallel interface. Crop and several image formats

are also supported by the MCU.

The DCMI interface is most compatible with OV9655 cameras.

Figure 11: OV9655 camera connected to DCMI port

LCD Interface

The Koala EVM Board includes an interface for a LCD module with touch screen.

Display is controlled through the FSMC interface. Touch screen data is read through SPI interface and GPIOs are

used for touch screen interrupts.

The connector assumes a LCD controller IC is built into the LCD module.

To use the LCD, a jumper must be placed across CN21 pins 2 and 3, as illustrated in Figure 5.

CAN Bus

The Koala EVM utilizes a driver (SN65HVD230) to interface to anexternal CAN Bus.This allowsthe MCU to create

a node on the bus and communicate with other peripherals in an automotive setting.

Ethernet

The Koala EVM features an Ethernet interface and physical layer (DP83848I), allowing it to connect to a wired

network for communicating with other LAN devices.
