在前個例子“I2C –向 Arduino UNO 發送資料”裡, Ameba 是I2C master, 而Arduino UNO是I2C slave,並且讓Ameba 送資料給Arduino UNO。 在這個範例裡, Ameba 一樣是I2C master, Arduino UNO 是I2C slave, 但是改成資料從Arudino UNO 傳給Ameba。

Your problem boils down to "I receive arbitrary number of bytes at a time as I2C slave, how do I know the transmission has ended". I will use STM32F103 (used in Blue Pills and Nucleo boards) as an example, since I have its documentation at hand. Its I2C has STOPF bit, which in ...
I've successfully set up a toolchain to program the KL25Z dev board, and I need some kind of help using I2C! I'am trying to access the onboard inertia sensor, I can address it correctly, I receive ACK on my commands, but when I want to receive data, I cannot get the proper data...
没理解您的意思，我之前理解I2C_MASTER_CMD_BURST_RECEIVE_START就是接收命令的意思，还要设置什么指令吗 这个是我想要连续读取的代码但是，I2c处于busy状态，不知道为什么。不
