Safety precautions

Safety precautions

Note:

Please note the following warnings regarding the hazards associated with development systems.

Safety precautions
Warning: The evaluation or reference board contains DC bus capacitors which take time to discharge after removal of the main supply. Before working on the drive system, wait for five minutes for the capacitors to discharge to safe voltage levels. Failure to do so may result in personal injury or death. Darkened display LEDs are not an indication that capacitors have discharged to safe voltage levels.
Warning: The evaluation or reference board is connected to the grid input during testing. Therefore, high-voltage differential probes must be used when measuring voltage waveforms by oscilloscope. Failure to do so may result in personal injury or death. Darkened display LEDs are not an indication that capacitors have discharged to safe voltage levels.
Warning: Remove or disconnect power from the drive before you disconnect or reconnect wires or perform maintenance work. Wait for five minutes after removing power to discharge the bus capacitors. Do not attempt to service the drive until the bus capacitors have discharged to zero. Failure to do so may result in personal injury or death.
Caution: The heat sink and device surfaces of the evaluation or reference board may become hot during testing. Therefore, necessary precautions are required while handling the board. Failure to comply may cause injury.

Caution: The evaluation or reference board contains parts and assemblies sensitive to electrostatic discharge (ESD). Electrostatic control precautions are required when installing, testing, servicing, or repairing the assembly. Component damage may result if ESD control procedures are not followed. If you are not familiar with electrostatic control procedures, refer to the applicable ESD protection handbooks and guidelines.
Caution: A drive that is incorrectly applied or installed can lead to component damage or reduction in product lifetime. Wiring or application errors such as undersizing the motor, supplying an incorrect or inadequate AC supply, or excessive ambient temperatures may result in system malfunction.
Caution: The evaluation or reference board is shipped with packing materials that need to be removed prior to installation. Failure to remove all packing materials that are unnecessary for system installation may result in overheating or abnormal operating conditions.

Getting started

2.1

Power up the lite kit

The CY8CKIT-4700S-PLUS kit can be powered from the USB port.

To power up the lite kit, connect the Micro-USB cable between the evaluation kit and the host system. The same connection (KitProg3) also provides the programming and debugging over the CMSIS-DAP interface.

2.1.1

Power from USB

By default, the evaluation kit is configured to run on 5 V. In case of USB power, the different sections power requirements are as follows:

· MCU power: VBAT from USB (5 V) or 3.3 V from LDO · mikroBUS power: 5 V from USB (5 V) or 3.3 V from LDO · XENSIVTM bus power: 5 V from USB (5 V) or 3.3 V from LDO · Arduino bus power: 5 V from USB (5 V) or 3.3 V from LDO · IFX bus power: 5 V from USB (5 V) or 3.3 V from LDO · Peripheral power: 5 V from VBAT USB or 3.3 V from LDO

Note:

5 V from VBUS or 3.3 V from LDO power could be selected through 0  resistors- Mount R129 for 5 V VBUS or mount R130 for 3.3 V from LDO.

Hands-on shipping firmware

The CY8CKIT-4700S-PLUS kit comes with preinstalled firmware to check all the onboard peripherals.

2.2.1 Hardware and tool setup
To check the preinstalled firmware on the CY8CKIT-4700S-PLUS kit, follow these steps to set up and communicate with the host system:

Figure 4 CY8CKIT-4700S-PLUS Evaluation Kit and tool setup
1. Connect the USB cable from the PC to the evaluation kit. The evaluation kit is powered by the PC via the USB cable (5 V). Ensure that the power LED2 (blue LED) is turned ON.
2. When powered ON, the PSOCTM 4700S Plus device starts executing the pre-installed firmware, which can be confirmed by touching the inductive sense buttons and observe the respective LED glows.
3. Also, confirm by using the metal target near the proximity sensor and observe the proximity LEDs glowing as the metal target move towards and away from the sensor.
4. To communicate with the PC, set up the serial terminal on the PC to send and receive messages to or from the evaluation kit. Follow these configurations in the Termite:
· Port: COMx KitProg3 USB-UART (COMx) · Baud rate: 19200 · Data bits: 8 · Stop bits: 1 · Parity: None · Flow Control: None

2.2.2 Software checks
The evaluation kit comes with the pre-installed firmware when turned ON, it starts executing. After completing the tool setup, follow these steps to check the firmware and lite kit features:
1. Reset the PSOCTM 4700S Plus device using the reset button (SW2). 2. Press the user button (SW3) to toggle the user LED7 (green LED). 3. Touch on any of the inductive sense buttons (BTN1, BTN2, BTN3) and verify using the onboard LEDs (LED8,
LED9 and LED10). 4. Take the metal target near and farther from proximity coil to see the onboard LEDS (LED3, LED4, LED5 and
LED6) turn o and OFF gradually. 5. Also monitor the UART terminal (Termite window) to see the raw counts of all the four sensors. Observe that
the row count increases when a touch is detected.

Inductive sense buttons

The CY8CKIT-4700S-PLUS kit has three on-board sensor buttons and one on-board proximity sensor coil. The sensors use the inductive button coil and proximity sensor coil which are connected to LX and RX each. It works on the principle of oscillator-based inductive sensing.

Three dedicated LEDs are available on-board (LED8, LED9 and LED10) to indicate the events on the sensor buttons (BTN1, BTN2 and BTN3) and four LEDs (LED3, LED4, LED5 and LED6) are available to indicate the events on the proximity sensor (PROXIMITY).

KitProg3 USB program interface

KitProg3 is the Infineon low-level communication firmware for programming and debugging. It provides communication between the programming tool (Auto Flash Utility) and a target PSOCTM 4700S Plus device.

KitProg3 uses the industry-standard Serial Wire Debug (SWD) protocol. It uses CMSIS-DAP V2.0.0 and V1.2.0 as the bulk and HID endpoint transport mechanisms.

KitProg3 also supports bridging: USB-to-UART and USB-I2C. For more information, see the KitProg user guide.

Figure 10 KitProg3 USB program interface

Note:
User guide

By default, the bridging between the KitProg3 and CPU is configured for the USB-to-UART

interface. To use the USB-I2C bridge on the kit, remove the resistors from the UART position and

install resistors in the I2C position, see Figure 10.

7. Run the application by selecting the "Project_Name Program (KitProg3_MiniProg4)" under the launches in the Quick Panel.

Figure 17 Running the application
8. Ensure that the project name is mentioned correctly; otherwise, generate the launches and then run the program.
9. Observe that the user LED (LED7) toggles every time the user button (SW3) is pressed and on every touch on the inductive sense buttons (BTN1, BTN2, BTN3), the respective LED (LED8, LED9, LED10 respectively) glows using a metal target the functionalities of the proximity sensor can be detected.
10. Also, open the terminal (for example, Termite or Tera Term), choose the right Com port: Kit_Prog port and set the baud rate to 19200. Figure 18 shows the raw counts of all the sensors are listed in the terminal window.

Note:

The mtb_shared folder will be present in the ModusToolboxTM_worspace folder and can be copied to the IDE is required. However, it is not mandatory to import it.
