利用IIC接口的4路 ADC max1037，采集思路信号，通过在FPGA内部的构建DeltaSigma DAC软核，在VGA液晶显示屏上显示波形。 (IIC interface 4-way ADC max1037, collecting ideas signal the FPGA internal build DeltaSigma DAC soft-core VGA LCD display waveforms.)

说明：  PL 和 PS 的高效交互是 zynq 7000 soc 开发的重中之重，常常需要将 PL 端的大量数据实时送到 PS 端处理，或者将 PS 端处理结果实时送到 PL 端处理，但是各种协议非常麻烦，灵活性也比较差，直接通过 AXI 总线来读写 PS 端 ddr 的数据，这里面涉及到 AXI4 协议，vivado 的 FPGA 调试等。(The efficient interaction between PL and PS is the top priority of zynq 7000 SoC development. We often need to send a large amount of data from PL to PS for real-time processing, or send the processing results from PS to pl for real-time processing. In general, we will think of using DMA for processing, but various protocols are very troublesome and the flexibility is poor. This course explains how to use Axi directly Bus to read and write DDR data of PS terminal, which involves axi4 protocol, FPGA debugging of vivado, etc.)

The SPFD5408A, a 262144-color System-on-Chip (SoC) driver LSI designed for small and medium sizes of TFT LCD display, is capable of supporting up to 240xRGBx320 in resolution which can be achieved by the designated RAM for graphic data. The 720-channel source driver has true 6-bit resolution, which (The SPFD5408A, a 262144-color System-on-Chip (SoC) driver LSI designed for small and medium sizes of TFT LCD display, is capable of supporting up to 240xRGBx320 in resolution which can be achieved by the designated RAM for graphic data.
