£18-36 GBP / hour

I have been working to develop an IoT datalogger based on the Arduino platform, I have several separate projects which I would like to merge into a single solution. I intent to use the following components: - OLED - BLE nRF8001 - WiFi ESP8266 - Sound CODEC - SD Card (Data logging and reflash device capabilities) - Sensor I2C board - 2xAnalogue sensors -IR LED Sensor (IR Remote control) -RGB LED stip All the above components work with individually and now I want to pull them together into a single design and looking for someone that can support understanding the hardware and how multiple devices can be connected to the Arduino Teensy 3.2 board. I think the biggest problem will be the OLED, BLE, Sound Codec devices as there use the SPI bus and not sure how to connect multiple devices to the SPI. I would also like to understand if it would be feasibility to refresh the Teensy processor from an image file on the SD card i.e. place a .hex file on the SD card which on start up re-flashes the processor? I have developed the s/w and used the Teensy due to it's increased speed and larger memory compared to the other Arduino platforms. In the presentation you can understand the devices and the connections, the devices can be changed to suit the interface to the Teensy. These components were only selected due to the easy availability from adafruit, eBay etc and happy to exchange them for other components. Therefore, I am looking for the following 1) Understand the components and system 2) Provide a h/w circuit diagram providing a solution to connect up all the above compononens to the Teensy (note: No s/w is required, I can develop that) 3. Understand and provide feedback on the ability to reflash the processor from the SD card and if/what impact that will have on the h/w interface

Dear Client, Hope you are doing great. Thanks for the project post and providing an opportunity to bid upon. I am a skilled electronics & PCB consultant with more than 6 years of experience. I have appropriate knowledge and experience in Electronics and PCB designing. I am well versed with digital and analog electronics design. I can work on designs based upon new ideas, reference schematic and redesign/re-engineer circuit based upon actual PCB pics. I have worked upon several projects which includes MCU interfacing, sensor designs, accelerometers and Gyro designs, GPS/GSM designs, RF designs, Bluetooth (BLE2.0, BLE, etc), custom XBEE design, actuator interfacing, amplifier design, audio codec, memory units, USB/FTDI interfacing, battery/power management and many more similar projects. As per my understanding, you have integrated listed module (wi-fi, bluetooth, SD Card, etc) with teensy and now you want them integrated on single PCB hardwired interfaced with Teensy MCU. I have worked upon custom Teensy designs along with similar integration. The power supply, USB connections and other interface will remain on board. SPI bus will support all interface with daisy-chain pattern and interface for the same will provided. I will provide you the complete PCB files, Gerber files, schematic, Bill of materials with supplier codes, etc. Kindly contact for further details and references. Kind regards, Amit

Timothy Woolaver Electrical Engineering Consultant Thank you for your consideration of this proposal. This proposal is for the integration of several Arduino designs in to a single system. About half of my business is turning Arduino projects in to custom PCBs and developing the firmware. I am currently working on a project which has some of the same issues. It has: BLE (nnRF8001 SPI) Camera Arducam Mini (SPI) SD card reader (SPI) Real time Clock (I2C) Mag Card reader (UART) I have it all working but there were a lot of issues along the way. SPI conflicts with the BLE Peripheral library were the biggest issues. I have answers to all of your questions but there is not nearly enough room here to answer them. If you would like to respond to this posting. I can respond with an attached file with the answers and some design examples. I am an Electrical engineer with 25+ years of experience. I have designed and modified the designs of many products and PCBs during my career. Please view my profile to see if my qualifications may meet your needs. Thank you again for your consideration and feel free to contact me with any questions or comments you may have. Thank You Timothy Woolaver Electrical Engineering Consultant One milliamp

With SPI, you should have CS pin to enable/disable the device when the master trying talk to a specific device, the REQ pin should be used for that purpose, I have just done a integration project on ESP8266 wifi based with I2C sensors. I can help you on your project.

Hello There ! I'm excited to let you know that we have worked on Arduino and have expertise in Designing Hardware. We can prepare High Level Diagram and Help you connect all the hardware to Arduino Teensy Board. Normally we can connect many devices to SPI Bus via different addressing . In this case you need to connect many devices to SPI which is possible. Let's connect on chat for more details.
