When our customers are in the preliminary stages of launching a new SMART HMI project, they typically reach out seeking advice on the best way to start. With what can amount to a near infinite number of HMI design options and system feature combinations, brainstorming an embedded firmware project can quickly become overwhelming. Where does one begin? How does the firmware work? What level of detail is required now?
The most important lesson when dealing with firmware and software development is summed up by the saying “garbage in – garbage out”. What this means is that we, Epec, are not experts in our customers product or application. We are experts at interpreting clients" requirements and creating an executable project plan while educating on the pros, cons, risks, opportunities, and many other design options that can help solve our customers" design goals. This creates a critical need for our customers to formulate a requirements matrix of the system that includes the multitude of “must have” and “nice to have” design features in order to begin to manage costs. It is vital to gather as much detail as possible to be able to deliver the custom SMART HMI that our customer needs.
Going hand in hand with the requirements matrix creation is the goal to completely capture what the SMART HMI should do. Some products may purely function as a switch, where they interpret 9 switch actuations and send those “ON/CLOSE” switch statuses elsewhere. A robust firmware solution can do much more by creating locally interpreted and executed commands such as turning on the backlighting of a display when a switch is held down for 5 seconds or more. More complex examples include functions like triggering an alarm and flashing a warning message if a sensed temperature exceeds 100 degrees, or even diagnosing failures in a pump and prompting error messages. Firmware can truly execute a near infinite number of actions as long as there is sufficient power, hardware, and the robust code to drive it.
HMI displays range in complexity from simple discrete illuminated LEDs, to segmented alphanumeric LEDs, all the way to monochrome LCD screens and colorized touchscreens. The type of display can drive component selection, board layout, power, and I/O connections. Firmware can be impacted just as much so it is important to specify early on the type of display as this will go hand in hand with how the source code is prepared.
Spend ample time to identify the requirements to a fine detail. All interfaces need to be identified and documented. The project should not proceed until all parties agree to these requirements. This cannot be overemphasized.
Safety critical interfaces must be identified and addressed. Machine damage and, more importantly, human life may need to be considered. This includes accounting for SELV (safety extra-low voltage) requirements as well as firmware code to execute a command that would shut off power during a hazardous event.
The addition of a design verification step should be considered to ensure all the requirements are met. Typically, this should be an ongoing practice performed during firmware development by the code author. At the completion of the projection a design verification document should be completed that describes, in detail, how the firmware complies with the requirements matrix, item by item and requirement by requirement.
A careful assessment of the product service life should be considered to safeguard against lost tribal knowledge pertaining to the code. Quite often the original author is no longer available when it matters most. The developer should provide ample design documentation during firmware development to ensure efficient firmware maintenance for the future. As field released and BETA versions are stressed, maintaining proper revision control and notations within the documentation in a simple readme.txt file can save significant financial resources in the future.
When writing firmware, the tools (aka compilers) used should be documented and archived. These tool vendors can also go “obsolete” in the future just like components. Archiving said tool set is important because if future firmware modifications are necessary, one should use the EXACT tool set that was used on the original, regardless of tool set version updates. There are instances where these new updated tool sets will break the firmware functionality (sometimes this occurs in a subtle manner). This can create the need for expensive regression testing.
This list can change daily, and one would likely receive different lists of “must have” and “nice to have” functionality depending on the disciplines of the parties asked. For example, the marketing department’s primary concern could be color matching, logo placement, or the ability to run off battery power for 12 hours. Conversely, engineers primary concerns could be the ability to survive a drop from 6 feet or pass a 15kV ESD discharge.
The instructions for this firmware update was that it fixed the issue where the position of the cursor does not display correctly on the screen while using touchpad. Hopefully you installed it for that reason.
Have you tried an external monitor? Are you able to see your information with the external monitor? If so, you may wish to uninstall the update and revert back to the original configuration. Then run systems diagnostics to troubleshoot that touchpad issue prior to downloading the update again.

Hardware manufacturers regularly release firmware updates so their devices remain secure and compatible with new media. For example, Android and iOS devices periodically get firmware updates that enhance their performance, add new features, and protect them against security threats and vulnerabilities. Updates for firmware for devices like game consoles and televisions are typically done by accepting prompts to download and install the latest patch.
Subsystems: These are semi-independent devices that are part of a more extensive system. Firmware at this level is embedded within central processing units (CPUs), flash chips, and liquid crystal display (LCD) units.
When a computer is turned on, the BIOS launches instructions that check the machine’s startup process for potential errors. It starts by checking the random access memory (RAM) and processor for faults, then checks connected devices, such as a keyboard and mouse, for any problems. It then checks for a boot sequence, such as Boot from Compact Disc Read-Only Memory (CD-ROM) and Boot from Hard Drive. Finally, the BIOS connects to the bootloader program, which wakes up the computer’s operating system and loads it in the RAM.
The original EFI firmware is used in Macs and can only support Intel processors. Unified EFI (UEFI) is a piece of firmware designed to replace the BIOS in new Windows computers and supports AMD and Intel processors. UEFI is used to load and start up operating systems in devices that run Windows 8 and beyond.
Understanding what firmware a device has is crucial to keeping the machine updated. The firmware version of a Windows device can be accessed through the command prompt using an upgrade assistant.
The Firmware Upgrade Wizard is the most universal and preferred method of updating. If a previous version of the Firmware Upgrade Wizard or Firmware Images are installed, delete the old version and download the latest revision.
Note: UPS models with only USB communication port will have to wait for the next release of the FIRMWARE UPGRADE WIZARDwhich is expected to launch very shortly.
Every Smart-UPS has a unique UPS ID. This can be found in the "About" menu on the UPS LCD screen, or in the NMC web interface. The same models of UPS may have different UPS IDs depending on when they were produced.
The Firmware Upgrade Wizard will select the correct version for the unit you are updating. Note: it is not recommended to perform a firmware downgrade to a lower firmware version than the current UPS firmware.
If updating a UPS unit due to a "Needs Firmware Update" or "Battery Sys Error 0800" alarm, the external battery packs MUST be connected when performing the update. If more external battery packs are connected at a later date and the issue returns, the firmware update must be performed again with all battery packs connected. Updating an SRT UPS unit may take up to 20 minutes to complete. The more external battery packs are connected, the longer the update may take. DO NOT DISCONNECT THE UPS COMMUNICATION CABLE, REBOOT THE COMPUTER, OR ATTEMPT TO TURN OFF THE UPS DURING THE FIRMWARE UPDATE.
Note: Verify the hash key of the Firmware Upgrade Wizard after downloading. The current hash value is 6d70c461f03a35a975daf5e606f794b6. Open Command Prompt.
Change the directory to the folder where the downloaded Smart-UPS_Firmware_Upgrade_Wizard_v4.3.2.exe was saved: This is typically done using he "cd" command
For example, if the Smart-UPS_Firmware_Upgrade_Wizard_v4.3.2.exe file was saved to the Downloads folder, the command may look like: "cd C:\Users\Username\Downloads", or "cd Downloads"
After a software upgrade that includes an LCD firmware update, the LCD touch panel may remain stuck reporting an error indefinitely / for longer than 30 minutes:
The system is functional, but the LCD displays the firmware update screen indefinitely. The LCD cannot be used while it is frozen on the firmware update warning screen.
These messages indicates that the firmware update has finished, and the LCD is displaying the warning screen in error, so it is safe to perform the workaround.
With the dual screen mode, the MAESTRO really takes full advantage of its extra-large screen! Any display mode can be used in both single or dual display mode. In dual display mode, the real time display takes the upper portion of the screen, while any of the other displays (scope, needle, averaging or statistics) is set on the lower portion. The display in the lower portion can be easily changed using the parameters bar with drop-down menus in the center of the screen. You can also expand one of the displays to have it in full screen mode using the maximize button. Just as easily, you can go back to Dual Screen display by using the minimize button.
