![]() ![]() Line‑synchronized outputs ensure perfect synchronization of content across multiple displays for applications such as digital signage and video walls. Interactive functions such as gameplay and the use of a mouse are fluid and natural.Ī DM NVX system is engineered for stability and reliability. 2,3Įngineered for demanding conference room and classroom applications, DM NVX technology ensures real‑time, full‑motion 4K60 video performance for the presentation of multimedia, videoconferencing, and live camera images. Capable of handling a network AV installation of any size, the DM‑NVX‑350 includes features such as secure web‑based control and management, auto‑switching HDMI® inputs, a scaling HDMI output, video wall processing, an analog audio input or output, native AES67 transmit and receive capability, USB 2.0 and KVM integration, and support for copper and fiber Ethernet connectivity. The DM‑NVX‑350 is a compact AV over IP encoder/decoder designed to function as either a transmitter or receiver. Professional onboard scaling, High Dynamic Range support (HDR10), and HDCP 2.2 compliance ensure the ultimate in picture quality and compatibility for all of today’s varied media sources. Using standard network switches and CAT5e UTP wiring, a DM NVX system delivers a high‑performance virtual matrix routing solution that is economically advantageous and infinitely scalable for any enterprise or campus‑wide 4K content distribution application. This logic will be implemented in the future.įinally, it is easy to talk about the interface when I have it at hand, but it might difficult to understand how it works in reality.DM NVX® technology transports ultra high‑definition 4K60 4:4:4 video over standard Gigabit Ethernet with no perceptible latency or loss of quality. ![]() Also, there isn’t any code responsible for sending data to the generator’s web server and the code lacks some safety check functions, such as checking if typed value is correct and usable. Moreover, I might add additional functions such as login screen, ability to save parameters to the internal memory, etc. I haven’t mentioned any html/JS code in the post, because at this point the code is a huge mess and it is nowhere finished. Finally, there is an ‘Output’ button which will turn on/off generator’s output. Also, the buttons ‘Freq’, ‘Amp’ or ‘Offs’ works as ‘cancel’ buttons when you are typing in the parameter values. After typing in a needed number, and pressing one of the unit keys, input is saved and shown in the display. For example, if you press ‘Freq’, the units are shown: ‘Hz’, ‘kHz’ and ‘MHz’. Furthermore, when you press one of the mentioned buttons, numeric keypad is enabled (its color changes to yellow) and parameter unit keys are shown with units needed for a particular parameter. Then you are allowed to type in either Frequency, Amplitude or Offset respectively. To type in some parameters, you need to press one of the buttons: ‘Freq’, ‘Amp’ or ‘Offs’. Also, a button to the left from ‘…’ is also without any function. ![]() You can also see a ‘…’ button, which at this point doesn’t have any function, but it could be used as a menu or a ‘second function’ button in the future. The keyboard has waveform selection buttons, which will change output waveform between sine, triangle and square waves. You can see almost everything in the imageĪbove: the ‘display’ with needed information, and a keyboard for the user Let’s look on a basic web interface based on those several needs: Also, there should be a keyboard which allows user to type in the generator’s parameters. So, how should look the main control interface? I think that it needs to have some sort of “display” element where important information, such as waveform, frequency, amplitude, offset, etc., is shown.

Yet again this device is going to have the same features for connecting it to an access point and/or turning on its own AP. The WEB UI will be based on previous code which was a WEB UI for a temperature sensor. It is going to be either ESP32 or ESP8266, which are both Wi-Fi enabled microprocessors and can act as standalone WEB servers. Note, I started talking about WEB interface, which means that I have almost decided on an MCU to use. Means a starting point from which interface could be made more advanced withĪdded features, logic, design elements etc. Let’s continue building a signal generatorĪnd take another step by making a basic web interface. ![]()
