What would you suggest be the best way to add external memory to a Panda to create a large buffer?
For example, read an AD pin and store the values in the buffer, then apply FFT afterwards. This is just an example.
The thing here is the transfer must be fast from AD to memory, so…
- Preferably do it by moving from register directly into memory using the chip’s capabilities
- If memory is external, use an 8 or 16 bit port on static ram or fifo and move with RLP
- or use fast SPI based ram?
Is there anything that can be done to make such external memory part of the NETMF memory pool? It would be great to be able to do int[3][3000000]
I’m just toying with the idea of a basic Multimeter/Oscilloscope/Logic analyzer shield for students.
