一共有三种方式来发送和接收SMS信息:Block Mode, Text Mode和PDU Mode。其中PDU Mode被所有手机支持,可以使用任何字符集,这也是手机默认的编码方式。其中又分7bit-160,8bit-140,16bit-70的方式,我们中文用16bit70的方式。

For many years prior to the 1970s, engineers designed and built switch mode power supplies (SMPSs) using methods based largely on intuitive and exper- imentally derived techniques. In general, these power supplies were able to achieve their primary goal of high-efficiency power conversion; unfortu- nately, due to the lack of adequate theoretical analysis techniques, many of these power supplies only marginally met their desired performance require- ments. In many cases, they were considered to be unreliable.

FPGA读写SD卡读取BMP图片通过LCD显示例程实验 Verilog逻辑源码Quartus工程文件+文档说明,FPGA型号Cyclone4E系列中的EP4CE6F17C8,Quartus版本17.1。1 实验简介在前面的实验中我们练习了 SD 卡读写,VGA 视频显示等例程,本实验将 SD 卡里的 BMP 图片读出,写入到外部存储器,再通过 VGA、LCD 等显示。本实验如果通过液晶屏显示,需要有液晶屏模块。2 实验原理在前面的实验中我们在 VGA、LCD 上显示的是彩条,是 FPGA 内部产生的数据,本实验将彩条替换为 SD 内的 BMP 图片数据,但是 SD 卡读取速度远远不能满足显示速度的要求,只能先写入外部高速 RAM,再读出后给视频时序模块显示module top( input clk, input rst_n, input key1, output [5:0] seg_sel, output [7:0] seg_data, output vga_out_hs, //vga horizontal synchronization output vga_out_vs, //vga vertical synchronization output[4:0] vga_out_r, //vga red output[5:0] vga_out_g, //vga green output[4:0] vga_out_b, //vga blue output sd_ncs, //SD card chip select (SPI mode) output sd_dclk, //SD card clock output sd_mosi, //SD card controller data output input sd_miso, //SD card controller data input output sdram_clk, //sdram clock output sdram_cke, //sdram clock enable output sdram_cs_n, //sdram chip select output sdram_we_n, //sdram write enable output sdram_cas_n, //sdram column address strobe output sdram_ras_n, //sdram row address strobe output[1:0] sdram_dqm, //sdram data enable output[1:0] sdram_ba, //sdram bank address output[12:0] sdram_addr, //sdram address inout[15:0] sdram_dq //sdram data);parameter MEM_DATA_BITS = 16 ; //external memory user interface data widthparameter ADDR_BITS = 24
