- Creating a stand alone PCB with the NXP MCU

- Using __TIME__ will return GMT. Thought this was interesting since the compiler is hosted in the UK =P

1. What if Multiple binaries are stored on the MBED?  Which one gets loaded?

1. If multiple binaries are stored on the mbed then the one with the most recent timestamp is loaded.

1a. Can one binary call another? Or does multiple files get handled in the project before compiling?

 

2. Can the MBED be powered from an external source (not through USB)?

2. The mbed can be powered from an external source, but it is not recommended that you power up higher then 9V. Power is pin 2, it can take 4.5V to 9V.

There are answers and I could post them here but it might be better to do it on the forums where everyone can see both questions and answers.

Thank you Vlad. I will add these to my page.

 

I've slowed down more than I like to with this page.  Unf =( Real life always seems to get in the way =P

The actual input rating is 14v, but as the voltage regulator is linear it is not recommended to go above 9v as it can potentially overheat depending the system load.
