HEALTH AND SAFETY

• WARNING
  The Disc Pump Driver PCB Voltage must not exceed 48Vr.m.s. (where for a typical square-wave drive Vr.m.s. ≈ Vpk) at frequencies between 20 and 22 kHz. It is the user’s responsibility to ensure that the Disc Pump Driver PCB is used and/or integrated within any product in a safe manner. Read the appropriate user manual prior to first operation and take note of all safety notices.

• WARNING
  Take care during use of the Disc Pump Drive PCB not to create short circuits between exposed conductive parts of the board. Short circuits may lead to malfunctioning and heating.

HARDWARE AND SOFTWARE SETUP

This document describes two tools that could be used to program the pump control boards:

• Segger J-Link is more expensive and requires no additional hardware.
• ST-Link is a lower cost alternative; however, it is not able to provide sufficient power to the boards, so an external voltage supply is required (Note that the Development Kit and Evaluation Kit can be powered either by USB or by an external mains power supply, which is not included routinely with the Development Kit).

Segger J-Link

J-Link is a debug probe made by Segger (https://www.segger.com/products /debug-probes/j-link/models/j-link-base/).

J-Link setup

• Download and install the J-Link software and documentation pack from Segger’s website (https://www.segger.com/downloads/jlink/).
• During the installation make sure to select the options to install the USB Driver. This requires admin rights to install.

J-Link connecting to the Smart Pump Module
The following schematics and pictures show how to connect a J-Link to a Smart Pump Module. The electrical connections are made through the contact pads on the bottom of the module. Ensuring good electrical connection requires soldering or other means of maintaining good mechanical contact. The wires can be removed after the firmware is updated.

J-Link connecting to General Purpose Drive Board
The following schematics and pictures show how to connect a J-Link to a General purpose drive board.

J-Link connecting to Development Kit and Evaluation Kit Motherboards
The following schematics and pictures show how to connect a J-Link to a Development Kit or Evaluation Kit Motherboard; the programming pin configurations are identical.

J-Link enable 5V output

• The 5V output of the J-Link needs to be enabled to power the board for programming. Alternatively, you could connect an external 5V supply, like for the ST-Link.

• To enable the J-Link 5V, output connect the J-Link with a USB cable and open the J-Link Commander program by searching for it in the start menu. The J-Link should be automatically recognised:

• Type in the following two commands “power on perm” and “VCOM enable”. There will be no confirmation of the commands being received:

• Click Control-C to close the program. Unplug and plug in the J-Link to restart it. The J-Link 5V supply is now enabled. You only have to do this once for each J-Link.

J-Link firmware uploading

• Open the J-Flash Lite program by searching for it in the start menu. Select the STM32G030C8 device and set the interface to SWD at 4000kHz. Click OK to go to the programming screen.

• Once you have the programming screen opened, use the three dots to navigate to the binary file (.bin) of the updated firmware.

• Once the binary file is selected, set the Program address to 0x08000000.

To upload the new firmware:

1. Click the Erase Chip button. This ensures that there are no leftover settings from the previous version and that the new version can be installed cleanly. The log will confirm the device being erased:

2. Click program device. The log will confirm the device being programmed:

The device is now programmed with the latest firmware. Restart the device for the effect to take place. The version of the firmware can be confirmed in the top right corner of the PC application.

ST-Link

ST-Link/V2 is a debug probe made by ST (https://www.st.com/en/development- tools/st-link-v2.html).

ST-Link setup

• Download and install the STM32 Cube Programmer software from ST’s website (https://www.st.com/en/development-tools/stm32cubeprog.html).
• During the installation make sure to select the options to install the USB Driver. This requires admin rights to install.

ST-Link connecting to Smart Pump Module

• The following schematics and pictures show how to connect an ST-Link to a Smart Pump Module. The electrical connections are made through the contact pads on the bottom of the module. Ensuring good electrical connection requires soldering or other means of maintaining good mechanical contact. The wires can be removed after the firmware is updated.
• The power supply pin on the ST-Link can only power the board when the pump is not running so it is recommended to connect an external power supply.

ST-Link connecting to a General purpose drive board
The following schematics and pictures show how to connect a ST-Link to a General purpose drive board. The power supply pin on the ST-Link can only power the board when the pump is not running so it is recommended to connect an external power supply.

ST-Link connecting to Evaluation Kit
The following schematics and pictures show how to connect a ST-Link to an Evaluation Kit and Development Kit Motherboards. The power supply pin on the ST-Link can only power the board when the pump is not running so it is recommended to use the USB in or DC in for power.

Note: The above picture uses the breadboard only for connecting same colour cables together. The breadboard is not required to achieve the correct connection.

Note: The USB cable is used to deliver power to the Development Kit or Evaluation kit motherboards.

ST-Link firmware uploading

• In the first tab click the St-Link connect button. The ST-Link might have connected automatically in which case the button will say disconnect. In this case do not disconnect it. When the ST-Link is connected its light will go from red to green.

• Set the device address to 0x08000000. The ST-Link should automatically recognise the connected device as shown in the bottom right corner. Make sure the device is the STM32G03.

• Click the Read button. This establishes the connection with the device. The log will confirm data being read from the device:

• In the second tab navigate to the binary file (.bin) of the updated firmware. Set the start address to 0x08000000.

• To upload the new firmware:

  1. Click the Full chip erase button. This ensures that there are no leftover settings from the previous version and that the new version can be installed cleanly. There may be a prompt to confirm:

  • There will be a confirmation of the erase being successful:

  • The log will confirm the device being erased:

  2. Click Start programming. There will be a confirmation of the programming being successful:

  • The log will confirm the device being programmed:

  • The device is now programmed with the latest firmware. Restart the device for the effect to take place. The version of the firmware can be confirmed in the top right corner of the PC application.
