• In terms of standalone application development, what’s the difference between ACR88 and ACR89?

  ACR88 uses proprietary script language which imposes more limitations on functions and programmable size. Meanwhile, ACR89, having embedded FreeRTOS, uses C language, which is familiar to many users. C language also has more flexible functions and larger programmable size than those provided by the ACR88. The multi-tasking environment provided by FreeRTOS also makes it easier to develop complex applications.
