The sixth step, how to use the firmware of the lower computer
The target file of the lower computer has two "IAPISP.hex" and "AP.hex". For a new single-chip computer, for the
first time, you must use the ISP download tool of Acer Technology to write "IAPISP.hex" into the chip. As shown below.
No need to write after updating "IAPISP.hex" is the file. The "AP.hex" in the attachment is just a template for the user
program. When the download conditions are met, the user only needs to jump the PC value to the address of FA00H to
update the code.
