    We are looking for someone helping us to develop our own PCB Board and Firmware for a Bluetooth Low Energy (BLE) to Wifi bridge. Key components to be used are ESP8266 Wifi Chip with IOT SDK for communication toward the LAN / Internet. We will work together with you on this software implementation part. The ESP8266 should use it's serial ports to communicate to a TI CC2541 Bluetooth Low Energy Chip. The firmware part of the BLE chip can be ...

    Write small test routine to make motor go forward and backward. We should also be able to change the duty cycle of the PWM signal. If you're good, we have plenty more work. We interface to a TI DRV8837 motor controller.

    An embedded programmer is needed to implement embedded .c code for the interfacing the MSP430FR5969RGZ and the LMP91000EVM. Basically we must sweep the potential between the reference electrode (RE) and working electrode (WE) potential and measuring the current at the WE. The LMP91000 can provide both positive and negative bias, programmable from 0 to 24% VREF. Current from WE can be amplified with a programmable TIA_GAIN from 2.75K to 350K (or external resistor can be selected). We must validate ...

    We are looking at for someone to build the required code to execute the following function on a Cortex M3 with RN-XV WiFly Module (Roving Network RN-171)(could be substituted for Texas Instrument CC3000 if needed). The module should have the following behavior: Upon initial boot: operate in AP mode on a pre-defined SSID with a a local webserver on a fix IP. Webserver will receive a connection from a browser to input the AP. mode (open/wep/wpa) and ...

    Hello, I am working on creating an intelligent lighting fixture (much like this one in features but not looks http://www.vari-lite.com/vl-products/series3000/vl3000-spot/). I am finishing up the hardware and will have it produced shortly. What I will need is an embedded OS (thinking along the lines of a slimmed down Debian) and a programming running on top of the Debian (thinking C for speed). The program (again just thinking C) will need to do the following ...

    Looking for someone who can do PCB layout for me, preferrably with orcad layout. I have all schematic ready, footprints/padstacks of components ready. Board will be approximately 3x3 inch. Half of the board is already laid out (due to existing reference design). There are about 50+ components to layout and about 10+ datasheets that have details of layout guidelines. Multiple Engineers required

    We need a simple program to be developed for a PIC controller, The application required a loop to be run every five minutes to read all the sensor inputs and transmit it to a server via URL posting (GET method) using a GPRS module (preferrable a SIM900). The scope of this project is limited to just the controller programming as the server side programming is completed.
