基于FPGA 的正弦波三角波方波锯齿波，的电路图及VHDL的代码-FPGA based sine wave, triangle wave, square wave sawtooth wave, the circuit diagram and VHDL code, based on the FPGA sine wave, triangle wave, square wave, sawtooth wave, the circuit diagram and VHDL code

使用VHDL编写三角波输出，其中DA使用的是DAC902,一个12位的DA转换芯片(Use VHDL to write triangle wave output, including DA using DAC902, a 12 DA conversion chip)
