Hi Pals, does anyone know where i can find the application note 139 "In-system Flash Programming for 8051"???? I have searched the whole website http://www.keil.com but couldnt find it. waiting for an answer AAA
Why reinvent the wheel. Use an ISP derivative such as the P89C51Rx2 or P89C66x which have flash write built in and come with free software to download with. Erik
