How to enable 1.3 mpu6050 (Large End) and M4 FPU Original article. You are welcome to repost it. For reposted content, please indicate the source. The most recent time is the I2C of stm32. I know that the I2C of stm32 is not easy to use, because I have used analog I2C, and I have also written the AVR I2C, that is, the

compared the linux directory before and after the power plugging, but there was no clue when I looked for it for a long time. Why did I check CPU and memory for commands, check the power supply and there will be no command? Later, I found that this may not exist! I don't know the driver, I don't know the hardware, and I can't use the scripts written by others. I try to understand it. The following is your understanding. Please refer to Hai Han for errors. The first thing we can understand is th

Ibeacon is a hot topic recently. This technology enables indoor positioning, allowing your mobile phone to know if it is within the beacon range. Using this technology can produce many applications, such as helping you find your car in the parking lot, or providing coupons or location-related services in retail stores. There are many applications that we cannot imagine now. There are many explanations about what ibeacon is and how we can use it. However, from a technical point of view, how do th

The basic idea is to implement a parent device for the public part of these functions, in order to share certain system resources and functions, then each child function is implemented as its sub device, so that both resources and code are shared, and a reasonable device hierarchy can be achieved, the main use of the API is: Mfd_add_devices (), Mfd_remove_devices (), mfd_cell_enable (), mfd_cell_disable (), Mfd_clone_cell ().

ObjectivePeople who know about Bluetooth know that in classic Bluetooth, staying connected (Connection) is a fairly resource-intensive (power and bandwidth) process. In particular, when there is no data transfer, the resources consumed are completely wasted. Thus, for many Bluetooth devices (especially power-sensitive devices), it is hoped that it will be able to disconnect during countless passes. However, because of th
