RK引脚编号计算器
这段程序将一个GPIO引脚名称字符串(name)解析为数字表示该引脚的编号.具体来说,GPIO引脚名称的格式为"GPIO{bank}_{group}{pin}",其中{bank}为引脚所在的GPIO bank编号,{group}为引脚所在的GPIO组编号,{pin}为引脚在组内的编号.程序首先从字符串中提取{bank},{group},{pin},并将它们转换为整数类型.其中,{bank}从字符串第5个字符开始,{group}从字符串第7个字符开始,{pin}从字符串第8个字符开始.然后,程序根据以下公式计算出该引脚的编号:
bank*32+group*8+pin
其中,bank32表示该引脚所在的GPIO bank的编号对应的引脚编号的偏移量,group8表示该引脚所在的GPIO组的编号对应的引脚编号的偏移量,pin表示该引脚在组内的编号.最终,程序将计算出的引脚编号打印出来.
name = "GPIO1_A3"
bank = int(name[4])
group = ord(name[6].upper()) - 65
pin = int(name[7])
print(bank*32+group*8+pin)Recommend
