收到有一家国产32位
单片机开发板:
开发板做工不错哦,全部引脚引出:
- 3 颗 LED: - 电源指示灯(LED3),用户指示灯(LED1,LED2)
- 三个轻触开关: - 复位轻触开关(S3),用户轻触开关(S1,S2)
- USB 转串口芯片(CH340N)
- FLASH 芯片(W25Q64JVSSIQ)
- EEPROM 芯片(CW24C02AD)
芯片特性:
MCU可以接收4 ~ 32MHz 晶体振荡器,相对比
STM32f1不能超过16M,芯片超频看来可以的。
SDK 工程案例demo丰富,容易上手,SDKIdeSupportMDK有WHXY.CW32F030_DFP.1.0.3.pack
也有IAR配置文件。支持IAR MDK。完美!

总结:SDK官方写的比较全面,代码规整。芯片功能齐全,性能稳定,可以取代国外同类IC。
