I am working on storing data from Portenta H7's ADC through a high sample rate (>100kSa/sec) per channel. I am using 2 ADC channel for my work. Through the forum, I learned that the serial. print command reduces the sampling rate. Therefore one of the suggestions was to use the onboard available Portenta H7's 8MB SDRAM to store the sample values and then retrieving them after the sampling period. My sampling time is between 3-5 seconds so it is well within the storage limit of this SDRAM.
However, since I have no previous experience with microcontrollers, I am struggling to find a starting point for accessing this SDRAM for saving my data? Any suggestions from your side are most welcomed.
Please do recommend If you have any other ideas about managing the data for faster sampling.
You can find the Portenta H7 information here. https://store.arduino.cc/usa/portenta-h7. Portenta has STM32H747 dual-core processor.
Thank you all.
