Masters! I have a problem. I want to develop a program to read IC card reader on Arm board. IC card reader provides Windows.dll driver. There are three files: Mwic_32.dll, Mwic_32.lib, Mwic_32.h. I fi...
For example, if I want to get an 8MHz MCLK or SMCLK, when I use XT1 or the internal REFCLK as the reference source and multiply it through the FLL frequency-locked loop, I change the value of FLLN and...
The course of single-chip microcomputer application system is one of the main courses of electrical majors at present. It is very practical. For college students, classroom teaching alone is far from ...
My system is based on 8051 microcontroller, with 32K SRAM expansion, and its address space is 0x0000-0x7FFF, so only 15 address lines are needed. I use A15 (P2_7) as chip select signal, and expand 2 I...
