Hello.
I need add SDIO support to my development. I have download and install the SDFAT library and open the example TeensySdioDemo, compile and load to Teensy 3.6.
Now I run, and select option 1 for SdFatSdioEX, this work perfect, I check results in the Arduino Monitor Serie and there is a file in the SD card. These are data in Monitor;
size,write,read
bytes,KB/sec,KB/sec
512,16733.97,18772.84
1024,17299.63,18907.91
2048,16544.37,19059.21
4096,17457.50,19161.74
8192,17373.19,19207.90
16384,17273.20,19231.19
32768,17166.38,19241.91
totalMicros 6508199
yieldMicros 209248
yieldCalls 180
yieldMaxUsec 1433
kHzSdClk 45000
Done
But when I choose option 2 for SdFatSdio, this do not work, in the Monitor Serie windows, only see following text and there is not file in SD card:
size,write,read
bytes,KB/sec,KB/sec
512,
Somebody know why fail SdFatSdio option ??.
Its better and faster SdFatSdio than SdFatSdioEX ??
Seem that SdFatSdio work with DMA, so I understand that must to be faster than SdFatSdioEX. So if it's true, I prefer SdFatSdio, but in my current test this fail.
Kind Regards
