Embodiment Construction
[0016] The specific implementation manners of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0017] figure 1 It is a hardware connection diagram of a system using this software, including DSP, FLASH, MAX232EUE, and PC.
[0018] DSP: For the object that needs to be updated and configured, the DSP that needs to be updated must support the self-starting method and serial port communication, and start to execute the Control program segment to update after the self-starting.
[0019] FLASH: There are 3 programs stored in FLASH. The first segment is the DSP boot program, which is used to start the DSP; the second segment is the Cnotrol program, which is used to update the DSP; the third segment is the user program, which is the normal running program of the DSP. Replace this program when the DSP needs to be updated.
[0020] MAX3232: This chip converts the level format of the data, converts the digital signal of DSP into th...
