通过使用char数组,可以有效地管理内存使用。 使用reserve()函数:Arduino的String类提供了一个reserve()函数,可以在创建String对象之前预分配足够的内存空间。这有助于减少动态内存分配和释放的次数,从而降低内存碎片化的风险。 避免频繁使用String对象:尽量避免在Arduino程序中频繁创建和销毁String对象。每次创建Strin...
I’ve taken this format, because most firmwares use a reading range from 0-1023 and full integer values for temperatures. Repetier-Firmware uses a higher resolution for input and temperature and these factors convert old tables you may have into the needed value range for Repetier-Firmware. If...
