LEDs 4-3-5 (green-orange-red) are to display a 3-bit binary number (0 to 7), indicating which of the 8 waveform periods (OFF through 3.5s) is currently selected. 9. The digital data values of the waveform would normally be converted to analog voltages by the microcontroller’s digital-to-analog converter (DAC). Since you will not likely have an oscilloscope to display the waveforms, write the data values to a global variable named “DACvalue”, and display that value in the “Logic Analyzer” window of the Keil debugger. This will show the generated waveform, including...

I need a music visualisation (oscilloscope) app tweaking. It can be downloaded here Please choose the the 10.7 version for Windows. That web page also has some info about the app which might be helpful. To operate the app you drag and drop an audio file (mp3 or wav) onto it, and it plays the audio and gives you an animated waveform graphic which reflects the audio signal. It also outputs .png screenshots of the oscilloscope at whatever frame-rate you enter in the app's settings. This allows you do import these screenshots into a video editor and convert them into a video. Currently the app exports the oscilloscope graphics (.png screenshots) with a black background behind them. I'd like the app tweaked so that it export the .png files with a transparent ba...

Background: I am trying to control/interface with a Hantek 6254BC Oscilloscope using the provided Hantek SDK. I want to do this through software created with Visual Studio 2019 as a C# Windows Forms Application. Hantek provides Oscilloscope software which I can load and use on my computer but I want to connect with my own software using the provided Hantek SDK (DLL, Lib, .h. manual, code samples) . (Hantek6000BC SDK under download tab) The SDK Manual and Code comments are in both English and Chinese. There are several Dlls/Libs in this SDK, I specifically need to connect to the hardware Dll/Lib: , , HTHardDLL.h There are several methods I want to eventually access via my C# Windows Forms App (.NET framework) created

Hello, I am needing a simple charting (oscilloscope type) interface for our Arduino Leonardo board. By way of a simple example, we will have 3 floating point numbers between 0 and 1, such as "0.6, 0.334, 0.601" which will be output every 100 milliseconds from the arduino board via the serial port and the USB cable. We need a Windows application to chart these in a running chart, such as an oscilloscope. This particular open source project looks like it would closely meet our needs: : However, we would like to customize the project to chart these 3 numbers coming out of the Arduino and have a few options about the speed of charting and scale. We will also like to issue commands back to the Arduino by issuing simple text commands such as "S0.6", which

Hi, We just moved in a house in eastern Sydney and found several electrical related issues. Tried some electricians but seems they don't have sufficient knowledge or equipment to completely solve the problem. Issues we faced are: - High frequency electricity noise in the house, not sure where it's from. Probably need an oscilloscope to detect and locate the source. - Buzzing noise at the power points when they are connected and turned on -Flickering and buzzing LED lights after 10PM caused by 750Hz ripple control signal. Please get in touch if you have the related knowledge and equipment to help with the above.

dsPIC33EP256MC204 with I2C communicating with SI7051-A20-IM temp sensor and MPRLS0025PA00001A pressure sensor. I have a partial project with several known bugs that are unrelated to this issue. Neither I nor the person working the rest of it have the time to debug the I2C issues. Looking for someone with dsPIC33 knowledge, FreeRTOS knowledge, modest rework skills, and an oscilloscope to debug this and also to implement an I2C 'dejamming' bitbang process that I can provide code from a different dsPIC33 for. Ideally someone in the US as shipping hardware internationally is a pain.

We have a dc motor with encoder solution that appears to be loosing encoder pulses during operation due to signal corruption. The initial project is to discover where in the signal pathway that is happening by monitoring a number of places using a multi-channel oscilloscope and then a high level programming language such as Labview to compare the signals. It would only be a a few days work we would expect. We are based in London and the test equipment is on-site so reasonable proximity to London would be sensible. Happy to give full detail under NDA. Cheers
