B4R Library rSD32 library

it is a wrapper based on SD library in esp32 package for arduino.
SPI configuration is depending of esp32 version:
ESP32:
- FSPI = 1, SPI attached To flash / normally Not used
- HSPI = 2, uses SPI2 => MOSI (13), SCK (14), MISO (12), SS (15)
- VSPI = 3, uses SPI3 => MOSI (23), SCK (18), MISO (19), SS (5)
- VSPI is SPI by default

ESP32-S2:
- FSPI = 1, uses SPI2 =>MOSI (13), SCK (14), MISO (15) And SS (12) / 6 SS lines any other pin
- HSPI = 2, uses SPI3 =>MOSI (35), SCK (36), MISO (37) And SS (34) / 3 SS lines at any other pin
- VSPI Not defined

ESP32 C3:
- FSPI = 0, uses SPIx =>MOSI (5), SCK (6), MISO (7) And SS (10) / 6 SS lines any other pin
- HSPI Not defined
- VSPI Not defined


' * SPI Standard case: Connect the SD card To the following pins:
' *
' * SD Card | ESP32 | HSPI | VSPI
' * D2 -
' * D3 SS 15 5
' * CMD MOSI 13 23
' * VSS GND
' * VDD 3.3V
' * CLK SCK 14 18
' * VSS GND
' * D0 MISO 12 19
' * D1 -
' */
a personal configuration is also possible when pins are added in begin.

new functions in esp32 package are added:
byte getcardType();
ULong getcardSize();
ULong gettotalBytes();
ULong getusedBytes();
bool readRAW(ArrayByte* buffer, ULong sector);
bool writeRAW(ArrayByte* buffer, ULong sector);

[candide]

i think it is an issue due to esp32 package used:
C:\Users\saset\AppData\Local\Arduino15\packages\esp32\hardware\esp32\1.0.4\libraries\SD\src/SD.h:31:10: note: candidate: bool fs::SDFS::begin(uint8_t, SPIClass&, uint32_t, const char*, uint8_t)
=> esp32 v1.0.4 is used in your example

in my case, compilation is done with esp32 v2.0.2 and it is OK.
Also, If i look at esp32 SD library, we have a lot of differences between both releases, and it can explain your compilation issue.

Please to test compilation with last release esp32 v2.0.2 and we will see

 

[thetrueman]

Hi,
Where is library? Could not find it.

 

[candide]

Sorry, after a minor update, library was missing.

 

[thetrueman]

Thanks for sharing library but confused as it is v1.1 but in post #4 there is also mentioned a library v2.0.2...
Which one to use or please share both. Thanks.

 

[candide]

sorry for this mistake, the last one at head of this thread is the good one

 

[Mostez]

I'd like to thank you so much for sharing this great lib.
If I customized pin configs (sd.Initialize2) instead of using hardware SPI port, does it affect read/write speed or overall performance?

 

[candide]

with a google search "arduino esp32 change spi pins" you will have your answer :

standard pins used are depending of SPI interface used :
ESP32:
- FSPI = 1, SPI attached To flash / normally Not used
- HSPI = 2, uses SPI2 => MOSI (13), SCK (14), MISO (12), SS (15)
- VSPI = 3, uses SPI3 => MOSI (23), SCK (18), MISO (19), SS (5)
- VSPI is SPI by default

after you can change pins used :
If you use the pins shown in the table, you can achieve SPI speeds of up to 80 MHz.
If you use other pins, then you are limited 40 MHz. (in fact, most peripherals have a maximum SPI speed less than 40 MHz)

thank you so much
