LPC1768 In System Programming

Reza Ghochkhani

Dear all, Hi

I am using LPC1768 for a while now and I have always used J-TAG to program it. In my new project I need to use ISP procedure. I read the user manual but everything is vague and frustrating there about ISP. It did not even give me a head-start.

I was wondering if any of you have used ISP to place a program on the flash memory of microcontroller. please help me figure out what do I need to do.

With warmest regards

    Yes, thanks for your help. You too Gary.

    I read the manual very carefully and have a clue where to start. Whenever the ISP mode is requested, the auto-baud operation is raised. All you need to do is to send synchronization signal "0xF3" and wait for response. If everything is OK you proceed to the next step. It is a good place to begin with.

    I am configuring the required hardware to start in system programming using my own code. If any news comes up, I will share with you.
