STM32 Boards for Energy Monitoring

I thought of you OEMers the other day. I’m currently using some STM32 processors on a project unrelated to energy monitoring, but when I discovered the phenomenal ADC performance I couldn’t help but think what a great OEM platform it would make. It can do 12-bit conversions in 1 usec, do a continuous sequence of them in the pin-order of your choosing, and load the results directly into your C datastructure, all without any CPU interaction at all. Imagine an interrupt every 1 msec to say “I’ve just loaded those 1,000 12-bit samples you requested into your first array and I’m currently working on filling your second array with a new 1,000 samples”.
