Explanation of code, data, bdata, idata, xdata, and pdata in Keil C51

The 8051 structure provides the user with 3 different storage spaces, program memory ROM, data memory RAM (internal RAM and external RAM). Keil C51 defines different storage types through the following keywords to ensure that users can access the entire storage space of the 51 architecture. code: Access the progra

Android transplantation on TQ2440 development board

1. Current progress 1. Android can already run on the TQ2440 development board via NFS I recently compiled the android file system myself and ran it on TQ. It has more bin programs than the panda version, and the basic functions have been implemented. You can download the file system from: http://d.namipan.com/d/
