沁恒CH32V307VCT6最小系统板/开发板开源

沁恒CH32V307VCT6最小系统板，引出了所有IO口，一个Type-C连接到USB2.0全速OTG接口，一个Flash芯片 型号W25Q64 容量64Mbit 连接到SPI2接口，板上还有TL432电压基准1.25V(实测1.246V左右)可通过跳线连接到PC3的AD13，还有3.29V基准通过0欧电阻可连接到ADC参考电压VREF。

CH32V307VCT6简介

CH32V 系列是基于青稞 32 位 RISC-V 设计的工业级通用微控制器。全系产品加入硬件堆栈区、快速中断入口等设计，相比标准大大提高了中断响应速度。CH32V303_305_307 系列搭载 V4F 内核，支持单精度浮点指令集，具有更高的运算性能。在产品功能上支持 144MHz 主频零等待运行，并根据不同应用方向提供了具有特色的资源结构，例如 8 组 USART/UART 串口，4 组电机定时器，内置 PHY 收发器的USB2.0 高速接口（480Mbps），千兆以太网 MAC 等。

顶层：

TL432的1.25V（实测1.246V左右）电压基准可通过H8插跳线帽接到GPIOPC3的ADC13接口。

SW3是控制BOOT0和1自举引脚的，可以设置自举模式（具体看芯片手册2.5.2的 片上存储器及自举模式），都打到低电平（关闭）就行。

H9排针时用于接WCH-Link烧录代码用的。

H5排针是用于选择VBAT引脚的电源，如果没插电池就通过跳线帽接到3.3V电源，如果插了电池可接到BAT。

底层：

如果不需要外接VDDA电源和VREF要将底面的R11和R7接上0欧电阻，然后VREF+可以通过R8和R9选择接LDO降压出来的3.3V电源或者TL432输出的3.29V参考电压，正常接R9即可 另一个空着。

立创开源平台开源链接：https://url.zeruns.tech/Avda8

例程用了 Harmony LiteOS-M 系统，例程中建了3个任务，分别是：LED2间隔500ms闪一下，LED3间隔1秒闪一下，LED4间隔2秒闪一次。（上面的动图速度加快了1.5倍）

工程要用MounRiver Studio软件打开。
