RE: PSoC4 Smarter Life Challeng - DAS Project : Updates on Stage3 and Roadblocks

I'm actually a bit surprised about running to the end of the available resources; does that also come from using the SD-card code?

I've used Elm's code for SD-card in the past, and was able to strip it to a minimum for what I needed. Especially disabling strange languages helped a lot (utf-8 tables) in reducing code size.

Another great help is to make functions static where applicable (if only used in its own c-file), so the compiler can decide to either inline it or make function calls, depending on optimization for speed or size.

Very good post though: shows what happens when you're engineering. Last week I built a large construction out of wood, and in Sketchup it looked and fit great. In reality my walls were sloping slightly in two directions, so I had to 'tune' my design quite a bit during construction!

Great post, especially when you point out to beginners that just plugging cards together is not the total sum of engineering knowledge needed.

I was wondering if some of the more ambitious projects would exceed the onboard capability of the PSOC board.

It sounds like you can squeeze a bit more into the memory. Reminds me of one project where I had to implement a real time data collection and tracking algorithm into a MCU with just 2K by 16Bit EPROM. It took a while to get everything working, but the result was an awesome capability for the late 1970's.
