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 ...
Total Controls is a company that develops flight sim gear at a consumer level. We are now looking for a coder and hard ware reviewer for our new product. It will be a HID unit with a 50 button matrix 8x7 and a LCD display that can communicate and output info from the game DCS World. We need a USB Boot loader and firmware for this one time project.
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
We are looking for an engineer to support our team in the development and testing of our IoT devices. This requires a variety of skills and a good understanding of microcontroller hardware, embedded C programming, and mobile RF solutions for IoT devices (NB-IoT and CAT-M1). We work with optical sensors, so experience with embedded computer vision is a plus, as well as machine learning implementation on embedded systems. The work will consist of assisting in the development and testing of firmware developed in C, testing device functionality and identifying issues, recommending solutions and improvements based on test results, and communicating these to the firmware developers. Work includes understanding and testing: - Device microcontroller hardware and peripherals. - Firmware and device...
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 ...
I have a project done with Altium. The board is working but it needs some changes, I already made the changes in the schematic. I just need the layout to be updated and verified. There are about 20 netlist changes, none of them require the movement of parts of creating new ones. I need the updated PCB layout file and Gerbers for production. Thanks

Need skills: karnaugh map, JK flip-flop counters, design a digital system and draw the schematics on paper. I need you familiar with designing digital systems. Also on design/ draw the schematic. Xilinx.
I basically need a programming tool. I'm a tuner and i need to modify parameters of certian ECU type To do this i need a way to read data from MCU and write it back once i modify it This is engine control module for a car (Ford) manifactured by Siemens (SID212EVO) with Infineon Tricore TC298 processor , We need a way a read and write data from/to this processor , we have over 100 units awaiting modification so price is not a problem, none of current leading market ecu writing tools (magicmotorsport,alientech,autotuner) currently supports this kind of ECU , this particular MCU TC298 is also on other ECU's by different manufacturer (Bosch,Delphi) and alot of tools support it but apparently this siemens ecu is not yet supported by any tool yet . Probably enchanced security...
I have pt100 temperature sensor signal connected to plc put the signal is not stable as there is many noise come from vfd so I need low pass filter circuit to enter the pt100 signal on it to make filter of any other noise
i want to design a Microgrid with pid controller (Pso fuzzy pid, fuzzy pid, classic pid) in matlab to reduce frequency.

Hello, I have a arduino mega project with LCD, initially which was started with arduino uno and rotary encoder to feed commands. But now we want to upgrade it to arduino mega and LCD. We already have a code for the same and want to debug and add all the required codes and make a perfectly working model as per our needs. One should be very thorough with arduino mega and GUI design on LCD for the project.
GC Front Panel drawing using FreeCad and training on use the FreeCad to modify the existing Front panel draw. 1. I have the XL table with measurements parameters for parts and the parts position. 2. The Front panel will need to be expended to fit new Nextion 7" display with basal. 3. Final Front panel Draft size will be decided when drawing is operated by me.

Hello, As the title says, I would like to add some sort of antenna to the HM-10 BLE 4.2 module in order to increase it's range, so the bluetooth is discoverable at bigger distances. Looking to increase the range by 5-10 meters only, nothing big. I need someone that understands antenna design and has experience improving the range of bluetooth modules. Thank you! Marius
I need a code for arduino and the language is c++ for this project: Our project is an automated pillbox: It has arduino uno wifi, LCD I2C, keypad 4*4, buzzer (alarm), 2 IR sensors, 2 micro servo motors. 1- the patient will set the pillbox he will enter date/time. 2- he will choose number of medications (1 or 2). 3- he will enter the time and number of pills for each medication. 4- when it’s time to take medication 1 alarm will go on until the patient press the button on the keypad. 5- the door of medication 1 will open using micro servo motor. 6- there is IR sensor inside the compartment of medication 1 to sense the medication has moved or not. 7- the patient has to conform taking the medication if yes number of pills for medication 1 will reduce by 1 and upload to the cloud...

It is necessary to connect (write firmware) the nrf52840 microcontroller to android phone using Bluetooth Long Range (Coded PHY). It is necessary to control (turn on/off) the LED connected to the microcontroller from the phone.
Note: I'm looking for developers that have previous experience with GreenPak ICs I have a sensor that consumes ~300uA at 3.3v and I need to reduce it's power consumption by duty cycling it. The GreenPak design will need to power up the sensor, read the differential analog output, store the number of changes in a counter then power down the IC. The counter will be available via I2C for an external CPU.
