RE: webGPIO and webI2C implementations progress and introduction

Hi Anssi-san,
Thank you for your reply.
I'm planning to go to the airport by airport bus leaving the Hilton Hotel at 12:00, so it's okay.

Hi Takagi-san, 

There's a DAS WG F2F slot on Friday 20 September 11:00 to discuss webGPIO and webI2C: 

https://github.com/w3c/devicesensors-wg/issues/24


Please confirm whether that time works for you.

Thanks,

-Anssi

 Hi Anssi-san,
 I am planning to participate in TPAC all Thursday and until Friday afternoon. The only other thing I intend to attend is SVG CG, so I would like you to make a schedule according to the circumstances of the WG.
 
 Regards,
 Satoru Takagi

 Hi Takagi-san,
 
 DAS WG meets on Thu (full day) and Fri (until around noon).
 
 You are invited to join our meeting as an observer to share your progress on webGPIO and webI2C and to have a discussion.
 
 Which day would be your preference?
 
 We were planning to allocate some time for WebBT, Serial, and/or WebUSB and related discussions on either of the days given overlap in participation across DAS WG and WebBT CG & WICG. Your topic seems relevant in that context as Reilly pointed out.
 
 Thanks,
 
 -Anssi (DAS WG co-chair)

  Hi,
  
  Thanks your comment, I am considering participating in TPAC 2019 on Thursday and the day before or after.
  
  CHIRIMEN community is working on building environments and training materials that can control any low-level devices and chips directly from a webApps on a browser with common APIs (such as WebI2Ck, WebGPIO) using as many means as possible including Web Bluetooth and Web USB.
  
  Also, for the Device and Sensors API WG, CHIRIMEN's activities may serve environments that can easily implement working APIs for various sensors that are being considered by the WG using specific devices and chips as polyfills. Specifically, this page*1 of CHIRIMEN's training material has drivers for dozens of devices and chips written in javascript. These devices can be purchased from amazon and ebay for around a few dollars.

  This work seems interesting in the context of the Web Bluetooth API being developed by the Web Bluetooth CG and the Serial and WebUSB APIs being developed in the WICG. Will you be attending our F2F in Fukuoka next month?

  Hi Devices and Sensors WG member,
  
  I am working to make board computers convenient to use from web browsers mainly for STEM training materials as a member of open source communities. I imagine that our activities described below may be related to this Devices and Sensors WG.
  I'm happy if I have the opportunity to exchange opinions with you at TPAC 2019.
  
  For several years, Browsers and Robotics Community Group at W3C is studying specifications that allow the board computer's pins (GPIO and I2C, SPI in the future) to be operated directly from browsers, named WebGPIO*1 and WebI2C*1. While rough referencing webMIDI etc.

  *2: https://github.com/browserobo/WebI2C <https://github.com/browserobo/WebI2C> 
  
  And, CHIRIMEN community (outside W3C) is implementing these specifications and building training materials that package it.
  There are implementations for Raspberry Pi3*3, micro:bit*4, and mbed*5 board computers. For Raspberry Pi3, webApps running on browsers on the Raspberry Pi3 controls the pins directly, while for the others, browsers connected via web Bluetooth controls the pins on the board computers.

  *5: https://github.com/chirimen-oh/chirimen-TY51822r3 <https://github.com/chirimen-oh/chirimen-TY51822r3> 
  
  This training materials are also used in multiple activities to train young engineers related to IoT.
