M5StickC Plus/Plus2の 側面コネクタ（G0、G26）や GROVEコネクタ（G32、G33）に I2C接続するのであれば、チャンネル0（Wire）を使用 します。 チャンネル0（Wire）を外部の回路に接続するピンを変更するには、Wire.begin () でピン番号を指定 します。

In my last column [LJ, December 2003], we discussed how I2C bus drivers and I2C algorithm drivers work. We also described how to make a tiny dummy I2C bus driver. This month, we discuss how an I2C ...

マスター側として事前に設定する項目は少ないです。 LL_APB1_GRP1_EnableClock(Periphs); LL_I2C_Disable(I2Cx); LL_I2C_ConfigFilters(I2Cx, LL_I2C_ANALOGFILTER_ENABLE,0); LL_I2C_SetTiming(I2Cx, Timing); ...

The best part of I2C is that it is a bus that is available just about anywhere, covering a vast ecosystem of devices that offer it as a hardware-defined interface, while being uncomplicated enough ...

The availability of powerful I2C buffers that drive their I/Os on both sides to a nominal ground or ‘zero offset’ logic level allows the removal of noise introduced into one section of a larger bus ...
