#174862 - alternative programming 89C51RD2 microcontroller |
I have already built a programmer for an 89C51, which allows me to program it using the serial tx/rx pins via atmel flip. However I would like to know if it is possible to set up a system where a 'master' microcontroller is connected to another microcontroller via the tx/rx pins and able to program the second microcontroller with a predefined program. So basically any 89c51rd2 put into this system will be programmed with the predefined program. Eliminating the need for Flip.
I realise this sounds strange but any help given would be much appreciated. Eric |
