[OpenTRV-dev] SMD version of ATmega328P

[Damon Hart-Davis]

Hi,

We’re starting production engineering work in earnest very soon, and we’re going to need to support in-circuit programming to use SMD.

I believe the standard way to do this involves driving the SPI bus as for loading a bootloader.

I am concerned that this cannot be done without damaging the RFM23B attached to the SPI bus, or am I wrong about that?  What gotchas don’t I even know about yet?

Thanks

Damon
