In a recent project, I learned about the external Ram Extension of the AVR microcontroller, which is recorded here. In this paper, we use a single-chip microcomputer with a single-chip microcomputer as the testing platform and expanded 74hc573 (AHC series are used in the data section. However, I used the HC series to configure the fastest access speed under the 16 m crystal oscillator and did not find anything wrong, of course this is not a rigorous d

This article describes in detail how to migrate the NFC Reader library to the Kinetis k64f microcontroller. This article uses a real-world porting case to demonstrate the steps required to migrate the NFC Reader library to the sample target MCU. The purpose of this article is to serve as a guide for software developers to transplant the NFC Reader library into the MCU chosen by their design. NFC Reader Library Overview The NFC Reader Library is a se

GPS is converted into a hundred degrees longitude and latitude, and gps is converted into Baidu longitude and latitude Recently, Baidu's api is used for map positioning. Baidu's background sometimes stops to obtain the longitude and latitude, and the results are written by Apple. CLLocationManager is used to obtain the longitude and latitude in the backend. However, the latitude and longitude errors obtai
