Provide the proper and working code (C or C++) that we can use to update firmware through WIFI from our web-server. You will not be providing code for the web server, only for the micro controller. Once MCU comes up, it should realize if a newer version of the code is available on the web-server and then update the code. The web server is a custom web server(not Azure). The hex or bin file will be placed on the web server. It is important to note, we are not asking you to do any work or coding for the web server. We only require the portion of the code that will be loaded into the micro controller. The code you provide can be minimal, meaning that we will customize it later for our application. We are only looking for the functional framework that makes over the air updates (OTA) possible. We are looking for someone who has successfully completed this task and who can quickly and efficiently provide the code snippet required without trial and error. Please contact us with any questions you have. Please be available for a phone or Skype meeting to discuss the details of the project and make sure you fully understand the requirements.

We need to contract someone to help us get our USB port data link working on a new product. Although we have been able to get the USB port working using the off-the-shelf USB settings from the manufacturer, the issue is that we have been unable to get it working within Processor Expert on our RTOS (Kinetis KDS + MQXLite). Goal: Functioning serial port emulation via USB on the MK24FN1M0VDC12, under these tools/RTOS: -KDS -MQX-Lite -Processor Expert Deliverables: -Within 3 days of contracting, an analysis and report indicating tasks planned and level of confidence - this is our check-in to ensure you are going down the right path and sync on any questions - Within 1 week a functioning demo project on NXP development board - Within 2-3 weeks a functioning demo project on goTenna proprietary hardware Provided by goTenna: -NXP development board -USB serial interface, if not part of development board -goTenna hardware -Zipped Project/Solution source code of effort to date Provided by Innovation Design and Solutions (IDS) -KDS installed on development PC -PE Micro Multilink Universal JTAG Emulator -Cables, adapters, power supplies, etc. as required

Google is developing a Tangible Programming platform to help children develop Computational Thinking skills through coding experiences that are playful, tactile and collaborative. They enable programs to be created without needing a screen, using physical blocks, or 'pucks', that snap together. For example: We can control a robot through commands like 'GO FORWARD', 'TURN LEFT' etc. Each puck can be created out of simple materials such as cardboard, and a Capacitive Signature painted on it, using conductive ink. Their technology depends on reliable detection of Capacitive Signatures. So that it can read whether a puck is a 'GO FORWARD' or a 'GO BACKWARD' command, for example. We want to use this idea, but apply it in another way. The first step is to develop a proof-of-concept sensor to reliably read our Capacitive Signatures. Please take the time to read the attached PDF before making a bid. In order to be considered for this project, please include a concise description of how you would solve the Capacitive Signature problem, and how each requirement A through E will be met. Your bid should be for the first milestone (milestone A) only. Upon completion of milestone A, we aim to invite you to work with us on a longer-term basis.

Greetings, I'm looking for an expert on embedded electronics with experience integrating capacitative touch with Atmel ICs. The chip would monitor cap sensing and reduce power consumption by an order of magnitude. This is a short project with a 1 week deadline and you will be building, testing, and confirming a working design I'm based in Boston, MA. If you are nearby, I can provide the chips and equipment for the work.

We are seeking a hardware/ firmware developer to adapt a readily available in the marketplace embedded computer development board for our needs. The board should provide a network access option for our HMS series RF power amplifier for a remote control, remote status monitoring and instrumentation data using an embedded HTTP Web server accessible via TCP/IP over 10BASE-T or 100BASE-TX Ethernet.

We have a newly designed PCB board without embedded firmware. The board has (3 x FLASH ICs, capacitive TOUCH screen, MicroSD, Ethernet, power management for battery and POE, interface for WiFi or GSM module, NFC Mifare … etc.) we’re using Renesas MCU Rx Family (RX62N) – part number R5F562N8BDBG. For embedded software, we’re using Segger RTOS and we already did build a full operating firmware for another PCB board using almost same parts (modules). However, our electronic engineer has changed the interface Pins between the MCU and the modules (NFC IC, MicroSD, IC Flash, … etc.) which is using the following interfaces (SPI, UART, I2C, and GPIO). We need to reconfigure our libraries (SPI library, UART library … etc.) to work with the new board. Because we don’t have enough SPI and I2C interfaces in the MCU, we may need to use soft SPI and I2C. the following is list of the interfaces need to be configured/written to let the firmware work with the new board: - SDRAM IC interface - MMC Memory Card IC (SPI interface) - Capacitive Touch (I2C interface) - Serial Flash IC x 3 (all in one SPI interface with chip select pin) - EPROM IC (I2C interface) - LED Driver IC - RTC IC (I2C interface) - Configure 6 UARTS to communicate with other modules. - ADC for battery level. - RFID IC (SPI Interface) - Buzzer, Relay, LED, etc. - HID IC (UART Interface) - USB Host interface - POE IC (AS1834) I2C interface
