Hello All,
I've been playing around with SDFat_beta using the example ExFatLogger code for about 2 months now and it works well to record a single analog input via the onboard ADC on both the t3.6 and t4.0.
But...I have tried several micro SD cards one of which is supposed to be ridiculously fast but I keep hitting the same 75 kHz limit. I have changed buffer sizes in the code and I am using the dedicated SPI mode but can not seem to get past this speed.
So my question in can the ExFatLogger code be used to record a single analog signal at 1 Msps on a t3.6?
