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
What things might cause i2c_master_cmd_begin() to return a "timeout" error code (263)? My understanding was that the timeout, in the sense of the parameter passed to i2c_master_cmd_begin(), is just a timeout on putting the I2C sequence into a queue internally so that it can be ...
I am using the ESP32 function i2c_master_cmd_begin() as: err = i2c_master_cmd_begin(I2C_NUM_0, cmd, 1000 / portTICK_RATE_MS); and every now and then this function returns -1 (which is an error). Would there be a reason for this to happen? thanks,ESP...

您好，I2C 总线timeout的原因是因为SCL保持长时间的low电平，导致会触发一个中断，所以发生这个报错，我认为可能需要检查下slave是否处于hang up挂起状态。 您参考下这篇应用手册32.3.7.3部分关于I2C SCL timeout的描述：https://www.ti.com.cn/cn/lit/ug/slau367p/slau3...
The Microsoft I2C HID Miniport Driver service is a kernel mode driver. If Microsoft I2C HID Miniport Driver fails to start, the error is logged. Windows 10 startup proceeds, but a message box is displayed informing you that the hidi2c service has failed to start....
这个芯片SPD的信息可以通过i2c 总线访问读取。现在市面上出现一种把内存直接焊死在主板上的机器(不用DIMMs/SODIMMs可拔插),这种机器上会有一个固件,它会创建一个虚拟SPD,给OS访问就像跟正常内存拔插那种。具体这个情况的技术实现大致是把内存信息直接嵌入到SBIOS FLASH里面,SBIOS的启动过程会把SPD表从SBIOS FLASH...
