I believe that, as a beginner of stm32, everyone is learning by downloading routines from the official website. Now firmwave's latest version is 1.1.0, for http://www.st.com/stonline/stappl/resourceSelector/app? Page = resourceselector & doctype =
In the actual application of RFID, due to the large data volume, the customer needs to occupy multiple sectors and blocks. In the previous interface, only one block can be read for one interaction. When the data volume is large, interaction takes a
Single-chip microcomputer is not difficult programming problems! URGENT!!!!!!
Converts the 8-bit binary number in the R0 to 3-bit BCD, resulting in a 1002h~1000h (from high to low) unit of external RAM.
For example: At the beginning, the data in the
The type of memory determines the operation and performance of the entire embedded system. Therefore, the selection of memory is a very important decision. Whether powered by battery or mains, application requirements determine the type of memory (volatile or non-volatile) and purpose of use (storing code, data, or both ). In addition, memory size and cost are also important factors to consider during the selection process. For smaller systems, the memory provided by the
