#174886 - that is the what, but not the why 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.
What I have done on some occsions is to have a small plug on the uC PCB that fit a small external PCB with a MAX232(derivative) and associated circuitry that interfaces to a PC with FlashMagic (if you use Atmel, that would be Flip). Would that work for you. I can not see why you want to program from a uC, rather than a PC, and then remove the programmed device. I guess (we all have been there) that you have an idea that is not optimal Erik |
