Software for reading encoder with SSI protocol is needed for ARM (prefably STM32F407G-DISC1 or EK-TM4C123GXL cards). A software for position reading in every 200ms (or more) for an SSI protocol with different brands and bits is needed.. The position information should be send with a common protocol (RxTx, I2C, RS485 etc.). Technical Details - SSI encoder position information with (a touch of butto...

Looking for someone who can make modifications in existing electronic devices such as GSM tracker, or build a new one using Arduino/Raspberry Pi modules

Hello. we are looking to prove a proof of concept. We want to open and close a door with a stepper motor and a Arduino. The idea is tha we need to have the door to be safe. How can we make the steper motor to stop if some one puts their hand between the door and the frame? we cannot use IR sensor or anything on the frame of the door. I was wondering if somehow we can read when the motor is bee...

I'm looking for someone who is expert in PCB Design especially in Analog Audio circuit It's a simple circuit -Through hole converts to SMD -Reducing the noise of the circuit -KiCAD to Eagle I need someone professional who can improve the design I will provide you more details

Adapt PCB from Eagle to KiCAD and increase performance from current 80A to 200A with peaks of 400A (specify heatsink for the design). Theoretically, used MOSFETs (FDMT80080DC, two in parallel) should be capable to handle 200A requested currents if they are cooled properly, but heatsink must be calculated. Also the Würth press-fit elements are already capable to handle 200A in theory. Probabl...

We have a hardware device that has 100 ports. We have an issue where if we plug in a device into the port, and if the device is bad it may not communicate to our software, so we do not know the port is occupied or not... We were thinking about adding a proximity sensor to each port/bay that can let us know if there is a device added to the slot, and if the software doesn't recognize the d...

Hello, I have made a SAR 8 bits binairy coded ADC using method of 2 steps Successive Approximation, but it is a bit buggy. I need very experienced engineer in this field, otherwise it would just be loosing time. The simulation must be done in Cadence Virtuoso 6.x Thanks !

System need to generate alarm when any motion or movement detected by it during specified [login to view URL] should send sms to specified number when it detect movment.

I have an idea for a product which will consist of 3 components. The data that the 3 components collect need to then upload the data to a website.

It is desired to create a pattern plot for a signal received by a matrix of 8 antennas. The signal is processed using Root Music to determine the reception angle of the useful signal, and for beamforming   is used MVDR. The simulation is created, the signal must be taken over and entered into a pattern plot.

Hello, I need help with the modulation of my transceiver. I want to create a new header file with Wireless Development Suite and paste it into my library. Since I'm still relatively new to programming, I'm not sure what steps I need to take in this regard. To what extent, for example, something has to change in my own code.

Project is to help me develop a board layout that connects a GPS and SD card modules directly to a ATMEGA328P. Then assist with the programming of the Arduino chip. This is a educational project for myself. I am looking to learn skills during the development process, so I would like to work closely, watch and ask questions. If you wish to work alone without questioning do not bid on this project....

I have a weather station prosject. Its Arduino based weather sensor with Anenometer attached to it. Every 5 minutes its transmitting data to my Weewx server and then its shutsdown for powersaving. I need a developer to code a driver for weewx. So it can receive my text message or data from my arduino sensor. Then transform it so Weewx can understand it and archive it to the database.
