I'm trying to make a simpler approach to flash LPC1114 MCU.
If the MCU is reset while pin1.1 is held low it enters bootloader mode. I'm using a simple arduino sketch to drive reset & 1.1 pins via serial line.
It was pretty simple with reset:
I've just replaced my button with a transistor and it did the trick.
Now, with 1.1 pin I have the following setup:
i.e. by default it's not connected to anything, on button press it's pulled down. Well, replacing the button with transistor doesn't seem to work.
Any hints on how to fix that?
