AOSP kernel 4.9.112 Qualcomm Android bsp USB subsystem engineer

The objective of this project is to enable USB2.0 functionality while USB3.1 is in used on our device. Our device is Qualcomm XR1 (SDM710 chipset). It only has a single USB-C port which makes up by one USB3.1, one USB2.0 and one CC port. Due to the QPNP framework by Qualcomm, the DWC3 controller in the firmware does not seem to 'free up' USB2.0 when the USB-C is in used. Hence, we are looking for an expert that can help customize the relevant kernel drivers and enable the working of USB2.0 and USB3.1 simultaneously/concurrently through the DWC3 controller. this is the overview of our current system design. and we are facing issues with our USB-C because of our DP display (via DP ALT Mode). you may assume the DP display needs to be working at all times -> this mean USB3.1 and CC would be in used for the display all the time. so customization will need to (priority ranked as below): 1. free up USB2.0 so we can connect it to PC/peripheral 2. when USB-C is plugged in, the PD controller (PM670L) needs to switch from display to charging/supplying power. For this, you can assume display to be turned off right before you do the CC switch.

Bootloader for Arduino OTA DFU

Hi, I am looking to implement secure Over-the-Air Device Firmware Updates (OTA DFU) capabilities for an Arduino-based Bluetooth Low Energy project utilizing a nRF52840 microcontroller. The current firmware is written for the Adafruit Bluefruit Feather Express board using Arduino and Adafruit libraries. However, the existing OTA DFU approach only supports legacy unsecured connections. I need assistance developing a simple proof-of-concept demonstrating secure OTA DFU via Bluetooth Low Energy between the Feather Express and either the nRF Connect or Adafruit Bluefruit mobile apps. The solution must be compatible with the Arduino IDE to maintain compatibility with our existing codebase. Modifications to the Adafruit library are acceptable as needed to enable this functionality. Solutions relying solely on the Nordic SDK will not meet our needs unless the code can be ported back to an Arduino-compatible format. The deliverable would be a working example Arduino sketch (blinky) demonstrating OTA DFU via secure BLE to validate the approach before integrating it into our application and product firmware (not part of this gig). Please provide your rate for developing this prototype BLE OTA DFU solution within the Arduino/BLE ecosystem to meet these requirements. I look forward to reviewing any bids for this project.

Ruby On Rails / Visual C++ / MFC Developer Needed

We have a device that updates its firmware remotely via a Windows application. Clients connect their device to the computer via a USB cable and when the update process starts, it connects to our server, from where it gets the latest firmware. The Windows application that the client uses has been developed in Visual C++ / MFC, while the backend server application is in Ruby on Rails. This development is about 10 years old, it was working well until now, but for some reason the update process has started to fail. Scope of work: Your role will be to debug the Windows application and see what is preventing it from getting and applying updates to end-user devices. Hopefully this will be a good starting point to help solve the problem. Important Note: If you have read this far, it is probably because you are interested in applying for this job.

Metal Melting Induction Heater Using PCB Board(Firmware & Other)

Hi! I'm interested in building a customized Metal Melting Induction heater using Transformers and other electronic and electrical components. I'm looking forward to build a Metal Melting Furnace which will be electrical mainly for the purpose of melting and refining Gold , Platinum , Silver and Iron. I'm looking forward to work with someone who is expert in PCB Designing and deployment and most importantly who has enough patience to answer all my doubts and questions throughout the project. Someone who is well versed with electrical and electronic components , firmware , hardware and PCB Design will be best suited for the project. What I'm looking for: 1) A Metal Melting Furnace using PCB Board , various electrical and electronic components , firmware and hardware. 2) It should have feature of increasing and decreasing Temperature manually as per the requirement of melting point of different metals. 3) A ON/OFF Switch button , temperature indicator in Degree Celsius , increasing and decreasing temperature buttons to set the exact temperature and voltage indicator are must. 4) A "SET" Button. This button when Pressed will maintain the constant desired temperature. For example the melting point of Iron is 1800 Degree Celsius. Once the furnace reaches this point and this button should be pressed so that there is not drop or increase in temperature irrespective of external conditions or other conditions. 5) Maximum melting point to be reached is 2100 Degree Celsius. 6) It should be able to reach those temperatures within 10-15 minutes. 7) It should be compact , lightweight and can easily be moved from one place to other(although this is not a major requirement if we have to compromise on it's quality or design to achieve the same but I believe that something like this can be achieved considering the fact that we live in advance age) 8) It should be able to work with the help of capacitor batteries or any other Lithium Ion battery/Solar batteries or the batteries which are used in Trucks or any other external source of battery. 9) It should be able to take in 240V of electricity since in my country its the standard 3-pin socket output provided by the government. 10) It should be able to hold crucible for melting the metals. For reference I have included a few pictures of my idea of the design , you are welcome to share yours and guide me along the way pointing out any flaws or cons of the same , thereby suggesting something economical as well as good performer at the same time. 11) Most importantly incase there is some major voltage fluctuation during its operation , there should be some very strong safety measures built into it to avoid any major accidents. 12) The components used in the project should be economical(since wearing of components will occur over the course of time and hence very costly components need not be installed) easily available(although this is not a compulsory requirement if quality will be compromised) 13) You will have to design the entire circuit board , a board which is not sub-standard in quality but above a certain threshold of quality but at the same time which will be economical to produce. 14) Since it is a furnace its maximum weight holding capacity including the weight of the crucible should be 6Kgs. 15) It should also be able to work with lesser weight such as from 50 Grams. External design/look of the furnace can be worked out later once the design and testing is completed. 16) The Total weight of all the electrical components including PCB should not be more than 10Kgs. 17) A Graphite crucible will be used for holding the metals. 18) The project needs to be completed within 180 Days from the date of you joining the project. If you can check all the above 18 points , you are welcome to join the project. Minor adjustments can be made here and there but not all of the above 18 points can be compromised because otherwise it will defeat the very purpose of posting this project. Please note this is not for mass production or commercial use. Thank you.

Python IoT firmware required for embedded device

The hardware configuration is already sorted. I have a reasonable understanding of python and have looked into this firmware in a lot of detail already however this needs to be 100% reliable when deployed in the field. Please do not bid on this project if you are not 100% confident in being able to complete all these requirements accurately and reliably as breakdowns can not be tolerated. There are more details and specifics that will be provided upon start of the project and signing of an NDA – if there is key information that you need to bid, please message. When you submit your bid, please outline how you would approach each of the areas detailed below. I require firmware in python which will perform the following actions on a raspberry pi zero. For context this is for use in an embedded device so once programmed will only be able to be debugged and updated remotely. - Read data from a sensor (over I2C) and send to an API endpoint. - Send a status ping every minute or so to an API endpoint. - Allow ‘resetting’ to configure connecting to a network. - Allow OTA updating Also will require - Instructions to setup the firmware on the raspberry pi, including a shell script that can be run to install any packages. - Programming of LED status lights to communicate – two (red & green) - Remote logging – for debugging Further details on requirements: A deviceId body parameter and apiKey header is required in all API calls. Firmware should be setup to run as a system process to ensure it automatically starts on boot. - I2C sensor reading o Read 12 data points from this sensor o Send as JSON to an API endpoint. - Send status ping o This should be sent every minute to allow us to determine if a device is offline o Should include an indication of the network speed and the current firmware version. o Response includes a debug parameter – this should be saved somewhere to be accessed later – (see remote logging) - Resetting o This process allows the device to be connected to a network without directly accessing the pi. o Essentially this needs to allow a user to somehow send a wifi password to the device remotely. o I have a button connected to the pi which should initiate the process when pressed. o Open to suggestions on how this should work but needs to be super simple and not rely on any third party apps etc. - OTA updating o This should check for updates once per day from an API endpoint. The response provides a url to a zip with updated firmware. o The updated firmware should then be installed. - Remote logging o This should send all errors to an API endpoint o Any generic ‘info’ logs should only be sent if the debug parameter is true

Convert C code to Python

There is an existing MPLAB Harmony v3 bootloader I2C application that uses a e54_xpro to send a binary file from an SD card on the e54_pro development board (I2c MASTER) to a Curiosity PIC32mm development board. The MPLAB example program is here: https://github.com/Microchip-MPLAB-Harmony/bootloader_apps_i2c/tree/master . I want to port the e54_xpro half of the application under ../bootloader_apps_i2c\apps\i2c_bootloader\host_app_sdcard\firmware\sam_e54_xpro.X to a python application. The bootloader code works fine with MPLAB X IDE 6.05 but has some minor library issues if you are using MPLAB X IDE 6.20. The goal is to use another I2C master connected to my PC with a USB port drive that chips I2C port to trigger the bootloader binary file transfer. I can send you the basic pyhon shell I would like you to use.
