Bear in mind that I2C is just a communicatiin chanell, the specific commands/data protocol it carries varies from device to device. bootloader Harmony 3 Bootloader C 3 1 2 0 Updated Feb 6, 2020. さてさて、こうなるとHarmonyのI2CドライバがDRV_I2C_TransmitThenReceive関数の呼び出しを受けて処理を開始し、各タイミングで発生する割り込みを処理し、送受信を完了させるまでの間にどこか問題があるということになって、一ユーザーがどうにかできるような. Arduino Forum > Using Arduino > Displays > I2C LCD // Example NewPing library sketch that does a ping about 20 times per second. A method of transmitting data through an I2C router from a source port to a destination port, the method comprising: receiving data in a first I2C source port buffer of the I2C router; capturing the I2C destination port before the first I2C source port buffer has overflowed; and transmitting the data from the first I2C source port buffer to the I2C destination port while restricting.
