  • 完成了 timer 驱动

[0.1.0] - 2019-12-17

@zyq

  • 修改了micro-uart 采样时钟高电平时间过长的问题

  • 实现了 printf 函数,默认波特率115200

  • 修改了 complex_core.sv/peri_req

    from

    peri_req = (data_addr & ~`PERI_MASK) == `PERI_START;

    to

    peri_req = (data_addr >= `PERI_START) && (data_addr <= `PERI_END);
  • 完善了 GPIO 驱动
