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。

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。
