  • Method and system for automatically setting addresses
    Patent number: 12326830
    Abstract: A method for automatically setting addresses suitable for an RS485 system is provided. The RS485 system includes a host device and a plurality of slave devices. The method includes the following stages. The host device confirms that there are no addresses of the slave devices in a database. The slave devices are turned on in sequence. The slave devices calculate their own respective power-on times. The slave device enter an idle state during the period associated with the power-on time. Only one of the slave devices sends the power-on time to the host device when said slave device leaves the idle state. The host device sets the address of said slave device according to the power-on time when said slave device leaves the idle state.

  • CONTROL DEVICE AND ACCESS METHOD
    Publication number: 20230214538
    Abstract: A control device is provided, in which the control device is coupled to an external memory and includes a storage circuit, a memory mapping circuit, and a central processing unit (CPU). The storage circuit stores a firmware image. The memory mapping circuit divides the firmware image into a plurality of segments and calculates the start address of each of the segments and the identifier code to generate an access sequence. The CPU reads the storage circuit and outputs the segments to the external memory according to the access sequence.
