i need a a complete HW/SW solution to make a wifi microcontroller board that transmits/receives digital signals and connected to a camera. the signal should be received at our server with a web page controlling the board and the camera

I uploaded the MATLAB Simulink for 3 phase motor driven by 3 phase Inverter, and feeded by SPWM. I need MATLAB simulink for single phase motor which is driven by inverter, and the common mode volta...MATLAB file I shared, also the parameters for SPWM. For this u should use active noise cancellation, which means, that it's forbidden to use passive components like for example resistors, capacitors, or inductors. You should only use active components which can be used later to program a microcontroller, this microcontroller is TMDSCNCD280049C. All the Blocks which will be used in Simulink should be compatible with the Microcontroller TMDSCNCD280049C. you can find the support package for the microcontroller, which belongs to the C2000 family in The project s...

...will negotiate with the ESP32 the access to the SDcard. The Teensy will also need to tell the ESP if is currently “busy” performing other operations and cannot satisfy this request. With a quick google search, you can find few examples for the ESP32 to do this, however they are all based on a different ESP32 module and they are accessing the SDcard connected to the ESP not to an external microcontroller. But modifying one of those would be a really good starting point. A few very important things: • MUST work on the ESP32-WROVER-IE-N16R8. No other types are accepted. • The code must run on the Teensy board 4.1 or 4.0. no 3.5 or 3.6 • The electrical connection must be identical to the one provided. • The ESP32 should be set as Wifi Access point ...

This project requires the pulsing effect of a white LED light as 3 arrays to wave outwards, I have attached a video of how the lighting will need to be placed and the overall effect im looking to acheive, the lights will be behind some perspex to diffuse the light this will be coloured blue and only show through in certain areas. Ideally the light in the middle will light up first, this happens at a voltage of 2.5v and peaks at 5v, this will then dim and the second outer ring needs to go from nothing (2.5v to 5 volt then back to nothing,) a third outer array will then need to go from nothing 2.5V to 5v then back to nothing then the process will repeat. I will need a chip reccomendation, this will need to be programmed and full wiring diagrams supplied

We have an old Disk system that we are trying to read. I have written C code so that it can take a Logic Analyser capture of a Microcontroller creating a valid Disk pattern and it decodes it perfectly, if I use an Actual Disk drive capture then due to drive Jitter my C code fails to decode the drive data correctly. The MFM data is valid as an original machine loads the MFM from the Disk perfectly, it is merely my program that does not compensate. Notice the Data is a continuous single track, i.e. spiral as opposed to multiple tracks.

STM MICROCONTROLLER UART COMMUNICATION

I have a small closed network of PCBs, each with an ESP-32D as its controller. I am using an 18V power source that is connected to each with CAT-V on a custom (not ethernet pinout) format to feed the 18V and ground with two twisted pairs. There are two high voltage LM2596 buck converters that make 12V for a string of LED lights on one one node, and 5V that powers the ESP-32s and servo for another node. Communication between nodes is provided via CANbus using a 3.3V CAN transceiver (ESP-32 has CANbus available, just needs the addition of a transceiver chip: SN65HVD). The CANbus is working fine throughout. However, when I power the network and connect the nodes, I am frying the ESP-32s. I verified that the 5V pin on the ESP-32 is indeed only getting 5V so it is not being overdriven there. I ...

I have an Arduino Due and I want to use a mouse with it which has more buttons than a regular mouse as well as a scroll wheel. Arduino libraries do not support the device fully and I need device-specific drivers to use the device. The drivers would be written in C++ and would work on an Arduino microcontroller. I would need the driver to regularly poll the USB device and trigger interrupts when new information is available. I would need interrupts for the press and release of all buttons including a scroll wheel as well as the mouse movement. This is on a tight budget so please only message me if you are willing to work within it. I am not able to provide hardware however I can help with testing. I believe it could be mostly coded and compiled without access to the hardware, however...

Modbus communication Master slave

microcontroller is a compact integrated circuit designed to govern a specific operation in an embedded system. A typical microcontroller includes a processor, memory and input/output (I/O) peripherals on a single chip. Sometimes referred to as an embedded controller or microcontroller unit (MCU), microcontrollers are found in vehicles, robots, office machines, medical devices, mobile radio transceivers, vending machines and home appliances, among other devices. They are essentially simple miniature personal computers (PCs) designed to control small features of a larger component, without a complex front-end operating system (OS).
