#174885 - trying to clarify Responding to: ???'s previous message |
I would like to set up a device where a hex file (i.e real time clock program) stored in the primary microcontroller can be sent to the program memory of another microcontroller via the serial communication ports. When the secondary microcontroller is removed from the device and placed in say a real time clock circuit, it will perform the program installed on it from the primary microcontroller.
So basically I want to be able to erase any program memory and program one at89c51 with the use of another at89c51. Is this at all possible? Thank your reply. |
