1、FSMC全称是静态存储控制器，用来高速操作外部SRAM，NOR，NAND等，广泛用来驱动LCD MCU的FSMC配置在fsmc_nor.c，你也可以查阅相关资料。 2、此例程通过读写外部M29W128，熟悉FSMC的配置以及操作。(1, FSMC stands for static memory controller for high-speed operation of external SRAM, NOR, NAND, widely used to drive the LCD MCU FSMC configuration in fsmc_nor.c, you can also access to relevant information. This routine by reading and writing external M29W128 familiar with the configuration and the operation of the FSMC.)

Simple UART for FPGA is UART (Universal Asynchronous Receiver & Transmitter) controller for serial communication with an FPGA. The UART controller was implemented using VHDL 93 and is applicable to any FPGA. Simple UART for FPGA requires: 1 start bit, 8 data bits, 1 stop bit! The UART controller was simulated and tested in hardware.

HART 官方资料-HART协议采用基于Bell202标准的FSK频移键控信号，在低频的4-20mA模拟信号上叠加幅度为0.5mA的音频数字信号进行双向数字通讯，数据传输率为1.2kbps。(Official information-HART HART protocol based Bell202 standard frequency shift keying FSK signal at low frequencies 4-20mA analog signal amplitude is 0.5mA superimposed on the two-way audio digital signal digital communication, data transfer rate of 1.2kbps.)
