2023寒假一起练平台（2）- 基于STM32+iCE40的电赛训练平台

Feature

• Amazing GUI with Encoder & Keys
  • GUI framework made by myself

  Thanks to the hardwork of afiskon/stm32-ssd1306

• SPI Commu with FPGA
  • SPI Slave not using IP core but verilog to simu it

  Thanks to the hardwork of damdoy/ice40_ultraplus_examples

• Base DDS Func
  • Working on changes of Waveform, Frequency, Amplitude
  • Up to 1Hz-10MHz Frequency && 0.1-1V Amplitude
  • Ultra low power consumption

  Thanks to the hardwork of Senpai @基于小脚丫FPGA的电赛训练平台suki

Official Introduction

项目3 - DDS任意波形发生器/本地控制

具体要求：

通过板上的高速DAC（10bits/最高125Msps）配合FPGA内部DDS的逻辑（最高48Msps），生成波形可调（正弦波、三角波、方波）、频率可调、幅度可调的波形

生成模拟信号的频率范围为DC-5MHz，调节精度为1Hz

生成模拟信号的幅度为最大1Vpp，调节范围为0.1V-1V

在OLED上显示当前波形的形状、波形的频率以及幅度

利用板上旋转编码器和按键能够对波形进行切换、进行参数调节

Hardware

• 电赛扩展板 x1
• DAC模块 x1
• STM32+iCE40核心板 x1

Software

• STM32:
  • CubeMX 6.7.0
  • Keil uVision 5 + ARM_CC 5.06
  • CubeProgrammer(Use UART To program device)
• FPGA:
  • Lattice Radiant Software
  • Lattice IP Core(PLL)
• STEP LINK (on board)：
  • Use as a virtual u-disk to download program to FPGA
  • Use as STM32's UART.
• distributed version control :
  • GIT: you can see my every change

User Guide

Simple use it

1. Download the release files in the Bin_Files folder.
   1. .rbt is for FPGA, use programmer to program it,or STEP LINK and simply drag it to your virtual disk.
   2. .hex is for STM32:
      1. press boot,then plug it on your computer.
      2. pretty easy use STM32 CUBE PROGRAMMER software to download your program by connecting to it's COMx/TTYx serial name.
2. Enjoy your DDS.

elp me improve it

1. Fork it, make your change, make PRs.
2. I will accept/contact you if have PRs.
