ch32vxxx 烧写
ch32v003 烧写需 wch-link e [***e]；link无法烧写 需link ehttps://i-blog.csdnimg.cn/direct/0e88a417ef0a4344ad22c71abbf82930.png

使用三线烧写，不需要swclk引脚

使用串口发送数据；天问的开发板有bootloader可以直接烧写，但如果使用wch-linke覆盖了bootloader后，使用下面的

ch32v103 ch32v link可烧写
wchlink模式；tx gnd 毗连 切换状态；risv arm
risv 针对 ch32v ; arm ch32f
经常需更新固件 ispunitl

arduino 库 下载地址 使用
GitHub - openwch/arduino_core_ch32: Core library for CH32duino
1.0.3
ch32v003 WS2812B 可以使用TWCH32V003的WS2812库;需要调整主频为48M，GPIO_SPPED不调 ；arduino ch32v003 1.0.3 注意引脚
使用逻辑分析仪 抓取波形 ARDUINO NANO 与CH32V
PD_4 PD4 代表的引脚不同；PD4
// pinMode(PD4 ,OUTPUT);
//led.rainbowCycle(100);
直接使用寄存器操作 PD4操作
//((GPIO_TypeDef *)(GPIOD_BASE ))->BSHR = 1<<(4);
//delay(500);
//((GPIO_TypeDef *)(GPIOD_BASE ))->BCR = 1<<(4);
//delay(500);

Blink
Turns an LED on for one second, then off for one second, repeatedly.
Most Arduinos have an on-board LED you can control. On the UNO, MEGA and ZERO
it is attached to digital pin 13, on MKR1000 on pin 6. LED_BUILTIN is set to
the correct LED pin independent of which board is used.
If you want to know what pin the on-board LED is connected to on your Arduino
model, check the Technical Specs of your board at:
