Small control system requiring programming and assistance on site

Need somebody who has done procesing of signals in realtime with some DSP chip that is fast enough, and within normal consumer budget. Or FPGA, or whatever hardware configurations, that are available. The attached spike has a duration of aprox 7 microseconds and an amplitude of 0.1 to 5.5 V. The input of the spike is around 200hz. We are trying to push it to 500hz or more. I need sampling on each channel at least 7msps. The proccesing each sample set and curve fitting, to get the peak perfect precision mathematical peak with a precision of 2 miliVolts. Then the data is interpreted in order to maintain the Curve, and not get saturated, (with that triangle-ish shape img6303) and a control signal is emitted to lower the excitation and come back to the curve normal shape. These steps ...

• I need to monitor 5 outlets of 110VAC each and the temperature of an environment. • I need to know exactly when the energy drops and returns at each of the 5 points. • All energy and temperature points are in the same room. • There is a WIFI connected to the UPS and with a 4G chip. • The internet does not fail even in case of power failure. • Locally, there is a small server also connected to the wifi and the UPS that sends SNMP events to two external servers, ZABBIX and PRTG. • I need to monitor the drop and return of energy in these 5 energy points and know the ambient temperature. In short, on ESP32 or ARDUINO: 1) Make the list of material to be purchased; 2) Make a program that generates events via SNMP to a local server (cable or wifi) with a spec...

I have a board i need to fix for an equipment in my store. Looking for an FPGA expert that can debug the program files i got from the manufacturer. I was told this should be simple for someone that knows what they are doing.

Read the full description of the project first, don’t bid if you don’t have experience, questions are welcome if related to the project. The project intention is to have 2 esp32, one of them will connect to a wifi Network and will be communicating with the second esp32 via serial, the second esp32 will connect to another wifi. When the second esp32 receives a request of an image via URL it will connect to the serial uart, and download the image of another url in the first wifi network and present it in the second esp32. A diagram of connections is: Wifi(A)<->Esp32(A)<——uart——>esp32(B)<->wifi(B) Only the esp32(b) can request images from A

The batteries are 2S using 18650 or 21700 the cells we are currently using are Sony VTC6 3000mAh/20A and Molicel P42A 4200mAh/30A. Larger capacity cells will be investigated and used as they come available. They are housed in a nylon case and are wired in series having a centre connection for charging, there is no protection circuits in the batteries. They plug into our drones and controllers and will be plugged into the charger as required. The chargers are to accept either two or six battery packs and are to work with any number plugged in. We expect to be able to plug in up to six 2S battery packs which could be all at different charge levels and each will be balanced and fully charged on completion. An led showing fully charged will light on each pack when this is accomplished When ...

We have two energy meters supplying Modbus data. We want to capture the data from 6 data points : date, time, flow, temperature in, temperature out and electricity used and then provide a real time dashboard of information and energy calculations from the data. I would like this dashboard to be on a windows application but also allow the information to be supplied to a company wide Scada system. The information should have a feature to allow us to select the data from different time periods. eg daily, monthly annually as well as the real time information. The calculations will be simple formulas to allow the data analysis to be presented on the desktop. Outputs required on desktop: Time period Total flow Weighted average temperature in Maximum temperature out Temperature delta KW of en...

I created a Code for a Wallbox, so that Hotel Guests are able to use their Hotel Room Cards to start a charging process. The Code basically checks the validation of the Room Card, reads the Room Number of the Card, and transmits Room Number and the authorization to the MQTT Server. The Charging Station does the rest and sends an Email at the End. The Code works, but I have some hickups with collecting the mqtt Data of the current charging Rate and total Amount. Now I thought if it would be possible to use it with Tasmota, so I would be able to edit the Script from Remote, and don't have to flash the pcb onsite if changes are needed.

The 4 Data input panels will have a UI with Keypad for data input. The data should be stored in an excel sheet/google sheets/ any other data representation method. As it is an industrial setup, we need keypads that will ensure rugged usage. None of these panels will be connected to any of the machines in the industry. We just need this for data tracking of our products. So the user will just input the production data and that data needs to be saved some format.

I need to develop pressure sensor based coding for ESP32 mcu. Here, I am planning to use US9111 pressure sensor with mcp3421 ADC converter. I want to measure +5PSI to -5PSI pressure value, with auto zero calibration. When there will no pressure on the pressure sensor that must be zero value at the initial condition. It should be strictly maintain. It can be set by auto zero calibration. I want to measure pressure precisely, so you need to do the coding with exact calculation.

We look for an implementation of Art-Net 4 and RDM based on our implementation of DMX. We are using a Cortex-M 4 MCU (Artery AT32F-415 RCT6 MCU) The AT32F415 Series Reference Manual V1.04 can be found here: The implementation should be as hardware independent as possible, therefore the implementation of Art-Net is planned on the cortex-M 4 MCU and the UDP data from the ESP module is being transmitted using throughpass and SPI link. This is the specification of RDM: You can use various open source implementations for our implementation. This is an example for a RDM implementation: Similar for ArtNet: An implementation of DMX is being provided. Design and Implementation Constraints The software should be programmed in Standard C. The IAR extensio...
