1.把wch的ch55x系列单片机,移植到Arduino,制成所谓的“ch55xduino”:GitHub - DeqingSun/ch55xduino: An Arduino-like programming API for the CH55X
2.ch55x系列单片机比较(立创/云汉2022年12月报价)
(1)CH552T:2.66(30)/2(500)
Freq:6/24M,Flash:16K,RAM:1K+256,DataFlash:128,1*D,TSSOP20
(2)CH554T:5.18(30)/3.65(500)
Freq:6/24M,Flash:16K,RAM:1K+256,DataFlash:128,1*H/1*D,TSSOP20
(3)CH555L: 5(厂家报价)【推荐】
Freq:12/48M,Flash:63K,RAM:8K+256,DataFlash:1K,1*D,LQFP48
(4)CH556:
Freq:12/48M,Flash:63K,RAM:8K+256,DataFlash:1K,2*H/1*D,LQFP48
(5)CH557:
Freq:12/48M,Flash:63K,RAM:8K+256,DataFlash:1K,4*H/1*D,LQFP48/LQFP64
(6)CH558L:7.35(30)
Freq:12/56M,Flash:36K,RAM:4K+256,DataFlash:5K,1*D,LQFP48
(7)CH559L:8.26(30)/7.98(500) 7(厂家报价)【推荐】
Freq:12/56M,Flash:63K,RAM:6K+256,DataFlash:1K,2*H/1*D,LQFP48
(8)CH549L:3.6(厂家报价)
Freq:12/48M,Flash:63K,RAM:2K+256,DataFlash:1K,1*H/1*D,LQFP48
原则:Flash要大,引脚要多,不需要H,价格便宜。首选CH555L,其次CH559L,其次552T
3.相应支持(目前只有CH552、CH551、CH559,以及测试中的CH549):
4.Arduino下开发板管理器安装
GitHub连接不畅,尤其是json文件几乎无法运行,而发布者Deqingsun提供的Proxy所能下载的并非为最新版本,可采取以下变通方法:
点开GitHub - DeqingSun/ch55xduino: An Arduino-like programming API for the CH55Xhttps://github.com/DeqingSun/ch55xduino
下右侧“Releases->Latest”,下载“package_ch55xduino_mcs51_index.json”到D盘,文件->首选项->其他开发板管理器地址,添加“file:///d:/package_ch55xduino_mcs51_index.json”,如下图:
随后按照“开发板管理器”正常操作即可。可以看出,当下可用示例还是不少的。
