I am working on K70 with MQX 4.0 on a TWR module. In my project I want to store my high frequency acquisition data to RAM for fast processing. Since there is not enough space in SRAM I planned to use DDR memory while acquisition and processing. All the other times I want to disable DDR to reduce the power conception. Is it possible to enable or disable DDR dynamically in MQX ? . One thing I noticed that RAM selection is done before building our project. Is it possible to use internal SRAM always and enable DDR when necessary?
