Azoteq IQS7222A Evaluation Kit
Introduction
This user guide describes the operation of the IQS7222A Evaluation Kit. The EV-Kit consists of 6 parts:
- Stamp board
- Connector board
- Base board
- 8 button board
- Buttoned slider
- Inductive coil
- Perspex with magnet
To visualize raw data from the EV-Kit, the stamp board can be interfaced to
any personal com-puter with USB support, and IQS7222A software Graphical User
Interface (GUI). The purpose of the IQS7222A EV-Kit is to help application and
development engineers in evaluating the IQS7222A’s capabilities.
Setting up the IQS7222A EV-kit
To interface the IQS7222A Evaluation Kit to a PC we advise using the CT210A
(CT210A is sold with EV04 kit, but sold separately from EV02 kit).
Stamp Board and IQS7222A IC
The IQS7222A IC is located on the stamp board. Run the IQS7222A GUI.
To demonstrate the capabilities of the IQS7222A, we suggest evaluating with the supplied boards. After this evaluation, the user may want to develop their own boards.
Plug-in Boards
8-Button Board
Plug this board into the base board at the PLUGIN marked area.
Now perform the following actions in the GUI. > Click the “Start Streaming” button.
- Click on the “ACK RESET” button.
- Open “User Settings” and navigate to “Demo Settings”.
- Select the image displaying the buttoned slider
- Click on the “ATI ALL AND READ” button.
CH0 gives distributed data for CH1 to CH4 and CH5 gives distributed data for
CH6 to CH9. The numbers on the board correlate to the numbers in the GUI with
the following table:
Move the slider with magnet on to above the IQS7222A IC. CH10 shows the Hall- effect of the magnet. Evaluate the performance of the IC. After evaluation click the “Stop Streaming” button.4.2 Inductive Coil Plug this board into the base board at the PLUGIN marked area.
Inductive Coil
Plug this board into the base board at the PLUGIN marked area.
Now perform the following actions in the GUI.
- Click the “Start Streaming” button.
- Click on the “ACK RESET” button.
- Open “User Settings” and navigate to “Demo Settings”.
- Select the image displaying the buttoned slider
- Click on the “ATI ALL AND READ” button.
- Figure 4.4: IQS7222A GUI Example: Coil Board
- CH0 is connected to the small coil at the left top of the plugin.
- CH1 is connected to the small coil at the right bottom of the plugin.
- CH5 is connected to the big coil at the right top of the plugin.
- CH6 is connected to the big coil at the left bottom of the plugin.
- To evaluate this plugin, bring a piece of conductive material close to a coil. The counts value should move upwards.
- A ferrite material will have the opposite effect. Bring the ferrite close to a coil and the counts value will move downwards.
- Move the slider with magnet on to above the IQS7222A IC. CH10 shows the Hall-effect of the magnet.
- Evaluate the performance of the IC.
- After evaluation click “Stop Streaming” button.
Buttoned Slider Board
Plug this board into the base board at the PLUGIN marked area.
Now perform the following actions in the GUI.
- Click the “Start Streaming” button.
- Click on the “ACK RESET” button.
- Click on the “ATI ALL AND READ” button.
See figure 4.6 below for an example
Figure 4.6: IQS7222A GUI Example: Buttoned Slider
The slider elements and buttons, as numbered in figure 4.7 are assigned to the
channels as shown in table 4.2 below. CH0 gives distributed data for CH1 to
CH4 and CH5 gives distributed data for CH6 to CH9.
