Inventek ISMART43362-E

Shield layer for Inventek ISMART43362-E Arduino Uno WiFi Shield. The shield is connected via an Arduino header using an SPI interface.

Provided API Interface	Description
CMSIS_WIFI	CMSIS-Driver WIFI (instance 0)

Consumed API Interface	Description
ARDUINO_UNO_SPI	CMSIS-Driver SPI connected to Arduino SPI pins D11..D13
ARDUINO_UNO_D9,D10	CMSIS-Driver GPIO connected to Arduino digital I/O pins D9,D10
CMSIS-RTOS2	CMSIS-RTOS2 compliant RTOS

Firmware

The ISMART43362-E Shield has two options to communicate with the underlying target hardware: UART and SPI.
By default, the module is flashed with the firmware for UART communication.
To enable SPI communication, follow these steps to flash the module:

Prepare the hardware

Set the power supply jumper on ISMART43362-E to connect 5V_USB and 5V_BOARD.
Set the SW3 switch to position 1 (factory default position).

Prepare the software

Download ISM43362_M3G_L44_SPI_C6.2.1.7.zip and extract it locally.
Download eS-WIFi_Demo
Unzip the file and install the application on your PC.
Start es-WiFi Demo and select Menu - Install Drivers and install both, CYW9WCD1EVAL1 and BCM9WCD1EVAL1:

Connect the ISMART43362-E to the PC using the Mini-USB connector. In Device Manager, you should see WICED USB Serial Port (COMx).
If not already done, assign a low COM port number.
In the es-WiFi Demo application, execute:
- Go to Setup - Serial Port - Configure/Open:
- Check the following settings (Serial Port being the one added just now):
- Go to Menu - Firmware - Update:
- Select the binary image file extracted in the first step (ISM43362_M3G_L44_SPI_C6.2.1.7.bin). Make sure it is an SPI firmware variant:

After the firmware is updated, the console will show the message "Resetting...":

You can now disconnect the module from the PC as it contains the new SPI firmware.

If you want to flash a different firmware later, please visit Inventek's Firmware page for the latest binary files.

Note: Firmware version ISM43362_M3G_L44_SPI_C6.2.1.8 is not supported!

Important considerations

For correct operation of the Sparkfun ESP8266 WiFi Shield using the Arduino R3 header, make sure that the jumpers are fitted as described in the table below:

Jumper	Setting
J26	closed
J27	1-2

For correct operation, the Sparkfun ESP8266 WiFi Shield requires a proper reset functionality ensured by connecting together the RESET pin on the Arduino connector with the RST pin in the area marked as ESP8266 GPIO, see the picture below:

Connection on the Sparkfun ESP8266 WiFi Shield

For stable operation, make sure that you are using an external DC 5V power supply (connected to J2).
Also, fit a jumper J1 to 1-2 closed and set the switch SW1 to position 2-3.
