    We are looking for a firmware/hardware developer who can create a solution helping us to use Alexa AVS in an industrial solution as an embedded device. Either based upon XMOS, Cirrus Logic or other reference design. Part of the job is to embedding, what is running in the development kits on an Raspberry PI to have one common PCB instead. Preferred would be firmware and hardware development combined, but we also can discuss of splitting the job.

    Good evening, i'm developing a smart device (IoT) that has inbuit BLE and GSM (2G) (simcon sim800c)connection. The microchip is the Cypress CY8C4127LQI-BL453. I need to develop a software (webapp) to control the device from remote and to download the data from the device. I need to setup the server too. Case 1: BLE connection with a mobile app (webapp) in the same room (smartphone, pc, tablet..) Case 2: device use 2G connection to connect with a smartphones or pc not in the same room (in another place) or throw internet (from website) An outsourcing company is already developing the PCB with BLE and GPRS and its working firmware. The communication protocoll for Bletooth is BLE (Bluetooth Low Energy) and I suppose the communication protocoll with the server should be HTTP using REST API for GSM I'm not a computer science guy so i need someone that will develop me the webapp (i already have the mockup of the mobile version) and configure it to work with the device (hardware).

    Hello Freelancers, we are looking for an ST expert to develop a firmware for the STM32F07 MCU used on our boards. CONTEXT The product is a keyboard with an integrated Hub and 2 flash storage solutions : one eMMC memory which stores a bootable LiveOS and a SD card reader external storage which is used for saving user-generated data from the LiveOS. Each memory controller and the MCU are each on a separate USB downstream channel, driven by a Hub IC connected to the host computer. HID USB keyboard capability as well as basic overall control of the board is provided by the ST32 and its firmware which is the topic of this job. MISSION GOALS The MCU firmware has to provide the following functions : 1) Process keypresses from the keypad switches (24 pins, row/columns) and transmit them to Host over USB using HID, providing standard USB keyboard functionality. 2) Capability of setting the eMMC memory controller in write protected mode or not, depending on the position of an external user-activated 2 position switch (On or Off). Programmatically this is simply setting a pin High or Low on the controller depending on the position of the switch at power on. 3) Induce an adjustable delay (starting with 30 seconds) for the detection of the external SD card controller at power on / boot time. This is to reduce the number of bootable device enumerated by Bios or UEFI in the Boot on USB menu/list. 4) Slow fade/breath a LED located in the product's Power push button when the side switch is set to Write protected and pulse it fast when set to Write Enabled. This is to let user know that memory is not protected. Switch is set to Write enabled only to write/install system updates, once every 6-8 weeks. 5) The firmware needs to be autonomous at product power-on and user-updatable via USB once factory-flashed for future developments or bug corrections. Code signing or similar mechanism to prevent unwanted flashing would be appreciated. GENERAL INFORMATION For someone familiar with ST products, the job's duration has been estimated to be short and its complexity quite low by an in-house PIC firmware engineer. Please share your previous ST products work when applying as we require robust ST knowledge and experience in order to move fast. The EE who designed the board can provide written guidance and support during the job. All schematics, keypad switch matrix table and a more precise written description for the above steps will be provided. A prototype test board may also be provided or testing/flashing can be done by us, depending on location and delays. We stress that, the product being built around PC and Mac "Boot on USB" options, the firmware must be operating rapidly in order to be usable straight away in low level bios. HID implementation must be clean in order for the keypad to be used during boot menu selection in Bios or UEFI. Provided timely delivery and all functionalities work correctly there will be more opportunities in the near future for additional jobs intended to implement additional features to this initial code. Thank you for reading, we are eager to find and start working with the right person for this project!

    I am trying to send the data from my DHT22 on the android nano over the NRF24L01+PA+LNA with Antenna to another board (Raspberry Pi with NRF24L01+PA+LNA with Antenna) But the communication isn't really fine. The distance between is only 20m but often the communication doesn't starts or I am getting connection errors.
