    Senior Field Application Engineer
    Dukosi Apr 2022 - Present
    中国 广东省 深圳
    Dukosi is a WBMS (Wireless Battery Management System) IC manufacture headquarter in Scotland UK. We are aiming to provide a brand-new patented BMS solution using NFC (Near Field Communications) technology, which combines advantages of both traditional wired and wireless solutions, meanwhile eliminating their shortcomings. It uses a isolated cable antenna guiding the low-energy 2.4GHz RF signal from all the battery cells to the hub manager. It significantly reduces harness cables, connectors. Not only reduces the cost, but also improves stability.I’m working on introduce our solution to potential customers. Demo our EVK, Q&A for them. Involve their hardware and software design. We provide our library reference C source suitable for vary microcontroller platforms. I help them porting the lib to their existed system. Eg: NXP S32 and Infineon TC2xx series.

  • Harman Embedded Audio
    Principal Embedded Software Engineer
    Harman Embedded Audio Jul 2012 - Jul 2015
    中国 广东 深圳
    Focus on the professional audio product's microcontroller and DSP software development.▲ I've involved the development of below products: cinema audio processor, Kara OK exciter, portable audio amplifier etc.▲ In microcontroller field, use Atmel 9G25/4S/3S (ARM9 and ARM Cortex-M4, M3) as the main controller for the cinema audio processor and Kara OK processor products. Microcontroller is to handle human-machine interface, menu (keyboard, wheel, button, LED, LCD etc.), audio codec SPI communication, DSP SPI communication, PC GUI (Graphic User Interface) communication with USB (by USB CDC – Communication Device Class). The firmware of microcontroller uses QNX (a Linux similar RTOS) in ARM9 hardware, uses uCOS or FreeRTOS real-time operating system in Cortex hardware.▲ In DSP field, use digital Butterworth filter to implement audio signal EQ, cross-over etc. process. Furthermore to handle delay, echo etc. and the communication with microcontroller thru SPI.▲ Implement boot loader for both microcontroller and DSP. They are used to inline upgrade MUC and DSP firmware in the future. I optimized the mechanism of boot loader provided by the IC company, I made it a real safety upgrade procedure. The system will never crash even the power is off or other unexpected scenario occurs during upgrade in processing.▲ ANC, AEC, NS etc. audio algorithm integrate to DSP hardware and software for headphones.

Successfully developed several applications based on Semtech products. Such as RF remote controller, Remote Keyless Entry(RKE), Automatic Meter Reading(AMR), house appliance▲Training in US and Switzerland for the RF, capacitive touch products. Familiar with their principal and application.▲RF technical support includes wireless tag projects etc. Wireless tag is a wireless management solution. It contains one or several base stations plus many slave units It is used such as super market, warehouse. Base station manages all the tag units, tags display item names, price, inventory information etc. It implements an efficient wireless management method. The communication between base station and slaves is 2-way radio. We finished RF protocol, RF packet format definition, firmware coding and debug.▲SX1230+SX1213 RKE(Remote Keyless Entry) is the first project I ran in Semtech. This solution provides 2 types of encrypt algorithms: Keeloq and AES. And I also optimized RF packet format and protocol. It makes Semtech solution has much stronger security than the on-market Keeloq rolling code IC. I finished the whole project including schematic, PCB, firmware, EVB and spec document, training materials. And I also conducted a training to our FAE during global FAE meeting in US headquarter.▲Develop API code(Application Program Interface), help customer coding Linux, Android driver, application, prototypes based on Semtech products.

New platform supports USB, PS/2 auto detect. I wrote the whole firmware. Products are widely sold in market.▲Use TI 27MHz RF chip with Sunplus microcontroller for wireless mouse keyboard receiver. I wrote the whole firmware. All Microsoft 27MHz wireless mouse keyboards on market are based on this platform.▲Porting and optimized mouse Z wheel algorithm to Sunplus platform. Mainly used in wired mouse. It has been mass production. I wrote the whole firmware. The algorithm uses a special skill, which allows the Z wheel PTR pair work well without sorting and has a longer aging life. To require supplier providing sorted PTR pair needs extra cost.▲Freescale QG4 microcontroller for wireless mouse battery recharge control. I delivered schematic and firmware. The system handles recharging a NiMH battery. It has full automatic charging feature including auto stop charging, over temperature protect, non-rechargeable battery detect etc.▲Nodic 2.4GHz transceiver nRF24L01 with Winbond microcontroller for Microsoft 2.4G wireless keyboard platform.
