I’m pretty new to the Arduino environment and just after some advice
I am looking at using an arduino mega to read an IMU and store the data.
The overall question would be, where should i store a large amount of data?
I would like to be reading and storing data multiple times a second. If possible something around 50times a second? or Is that to high?
If the IMU has 9DoF, that’s around 450 data values to be stored a second. Is this possible? If not whats the upper limit?
The data will be to 2 or 3 decimal places. So i multiply all the data by 1000 and store it currently as an int into the internal EEPROM.
The issue comes as i would like to log data over a 5 hour period.
450 data values per second
if each value take 4bytes
1800 bytes/second needed
32MB total storage space needed
Now i believe this sort of capacity is not available in an external EEPROM microchip?
Obviously a micro SD card could easily hold this amount of data, do these come in a microchip form?
As i don’t need it to be removable.
Or could i use some type of flash memory? Which i dont really understand currently.
