API ADC read and store

Post by Pineapple » Tue Nov 06, 2018 2:45 pm

Hi,

I'm trying to use the RP board to read the fast analog input form the ADC and store the data in the local memory.
The problem is that even if I install the RP OS on an SD card with large memory (tried using 16GB) the available space to store my data is always limited to 1.5GB. All the other memory not occupied by the installation of the OS seems to be inaccessible.

Is it possible to use that memory space in some way or do i need to find an other solution?

Thanks in advance to anybody that can help me out.

When you overwrite with the image from RP it creates two partitions on the SD card that have a fixed size regardless of the SD card you use.

To increase the size of a partition, use a partition management tool.
