I’m working with Digital Discovery device.
I try to log a SPI bus (its clock is 4 MHz); I tried to log the datas emitted.
As the clock is 4 MHz I’m tuning acquisition rate to 50 Mhz (in order to the device to acquire safely the datas): however it means that with 100M samples I will have only a 2 sec record size:
Is it possible to increase this record size (I would like to have at least 60 seconds)?
I’m perhaps not using the good way.
I want to have logs like this one , obtained after “export” (but larger size):
