ARM7マイコンAT91SAM7S256とW-SIMを使って天気予報を呼んでいる様子です。使用しているOKIのCODECチップの機能により音声出力データの符号ビ­ットの内容によりLEDが点滅します。この例では無音区間でLEDが消灯しているのが良くわかります。

  • Can you explain in english what does this?

    Is it a basic cellphone module?

  • Your guess is correct. I'm using Japanese PHS cellphone module called W-SIM which is connected to ATMEL AT91SAM7S256. This video dials to 'wheather forcast' service and hearing the announcement from speaker. You can see the LED is blinking synchronized with the announcement.

    All other videos found in "W-SIM" playlist are using this module.

  • So, if you try and add a screen and a "OS" you'll have a fully working cellphone?
