For the Arduino Giga how do you configure the SPI speed for use in the SD library for maximum speed, I have a device that supports up to 50Mhz SPI: https://www.adafruit.com/product/4899 Any help would be greatly appreciated thanks! :slight_smile:

Just as a follow on example. For listfiles example it would be: /* Listfiles This example shows how print out the files in a directory on a SD card The circuit: SD card attached to SPI bus as follows: ** MOSI - pin 11 ** MISO - pin 12 ** CLK - pin 13 ** CS - pin 4 (for MKRZero SD:…

would you happen to know how to get the sdfat library going using SPI1 and set the SPI speed?

Its been awhile since I had to change SPI but for clock you simply follow the example - this is from DirectoryFunctions.ino // Try max SPI clock for an SD. Reduce SPI_CLOCK if errors occur. #define SPI_CLOCK SD_SCK_MHZ(50) // Try to select the best SD card configuration. #if HAS_SDIO_CLASS #define…

awesome, thank you Merlin! :slight_smile:

Something like this might work: This worked for me on stm32f446re arduino platformio, static SPIClass mySPI2(PB15, PB14, PB13); // set for SPI2 SdFs sd; sd.begin(SdSpiConfig(PB12, DEDICATED_SPI, SD_SCK_MHZ(18), &mySPI2)); you need to do your own mods based on the example. Found that on: Does no…

@PCMaster2165 Could wait. This works. What was in previous doesnt work for the giga: // An example of an external SPI driver. // #include "SPI.h" // Only required if you use features in the SPI library. #include "SdFat.h" #include "sdios.h" #if SPI_DRIVER_SELECT == 3 // Must be set in SdFat/S…

[image] Using SD Cards on Arduino Giga? GIGA R1 WiFi Quick and dirty setup: [image] I modified the directory function example for SDFat... Note I have the Adafruit fork of it, so not sure how different... /* * Example use of chdir(), ls(), mkdir(), and rmd…

[image] KurtE: I think I had it working… Tried the example you posted with &SPI with Bills latest version of SDFat and its giving me errors: In file included from C:\Users\Merli\AppData\Local\Arduino15\packages\arduino\hardware\mbed_giga\4.0.10\cores\arduino/mbed/targets/TARGET_STM/TARGET_ST…

I am getting the following error: "Compilation error: #error SPI_DRIVER_SELECT must be three in SdFat/SdFatConfig.h" any ideas?

You have to edit the SdFatConfig.h file in the SDFat library and change SPI_DRIVER_SELECT from 0 to 3.
