CHIRIMEN FAQ

Q. What is “CHIRIMEN”?

CHIRIMEN is a development environment that allows to control the physical devices (such as sensors and actuators) only by Web browser technology and includes hardware (board computer) and software on it. Their implementation includes hardware as a board computer, Web browser software (currently using Boot to Gecko), and low-level device APIs (WebGPIO and WebI2C etc.) to control physical devices by web apps or JavaScript It is developed by CHIRIMEN Open Hardware community and code-named “CHIRIMEN”. Their hardware and software have been released as open source.

Q. What is the capability of CHIRIMEN?

CHIRIMEN can operate the contents within a screen, and a real physical device only with the technique of a web browser altogether simultaneously.

Q. Tell me about CHIRIMEN’s hardware.

Its hardware is an embeddable board computer with interfaces such as I2C and GPIO etc., and it assumes web browsers ) currently it is Boot to Gecko (B2G) ) as a prerequisite. The “CHIRIMEN Board Computer CMN2015-1” by the CHIRIMEN Open Hardware community is the first prototype hardware for CHIRIMEN.

Q. What has happened to the software part of CHIRIMEN? / What is OS of CHIRIMEN?

Currently, it is Boot to Gecko (B2G) OS. It is not Firefox OS. It supports Boot to Gecko 2.5 currently. Refer to the following clause for the reason which is not Firefox OS.

Q. What is Boot to Gecko? Does it differ from Firefox OS?

Boot to Gecko and Firefox OS is the same in code. After fulfilling conditions, such as quality and security, only the product which has obtained the licensing of the brand from Mozilla can use the name of Firefox OS. On occasions when it uses it as OSS without brand licensing, it is Boot to Gecko (B2G).

Q. What differs between Raspberry Pi, or other board computers and CHIRIMEN hardwares?

The hardware of CHIRIMEN is designed on the assumption that a web browser or comfortable operation of Boot to Gecko. Since a browser requires comparatively high graphics performance, it is mainly the feature in contrast to other board computers. Therefore, SoC designed for a tablet or STB is carried.

Q. What kind of devices and peripherals can CHIRIMEN utilize?

CHIRIMEN can utilize a cheap and general-purpose sensors and actuators with GPIO or I2C interface. The correspondence to the device using SPI or UART is also considered. Of course, USB can be utilized as an interface for keyboards, pointing devices, and network adapters.

Q. Who is making CHIRIMEN?

It was developed by the CHIRIMEN Open Hardware community. However, that community itself does not do manufacturing and selling of that.

Q. Can I reuse only the hardware part of CHIRIMEN?

Yes. However, assistance in particular of a software is not expectable from a community in that case.
