f82f699c64 reuse beginTransactionWithAssertingCS()/endTransactionWithDeassertingCS() 2022-05-02 22:37:27 +02:00
Christian Riggenbach
c00ec13218 moved setChipSelect() in front of beginTransactionWithAssertingCS() 
This is a more logical order, as beginTransactionWithAssertingCS() and
endTransactionWithDeassertingCS() both call it.

41635e3c68 beginTransactionWithAssertingCS() and endTransactionWithDeassertingCS() 
These two methods are similar to beginTransaction() and endTransaction(),
but, as the name implies, with CS management. They are both public, as
beginTransaction() and endTransaction() are too.

67bd6e7db5 Add a hack to work around the differences between the Adafruit SAMD core and the official Arduino SAMD core. 2022-01-21 18:12:50 -08:00

7f66a34b9c In the Adafruit_SPIDevice class, when running on the SAMD architecture in the hardware SPI case, use the SPIClass::transfer(txbuf, rxbuf, count, block) method when writing instead of looping over individual bytes. 
This makes use of DMA and is noticeably faster.

3bdfee4ab8 In the Adafruit_SPIDevice class, when running on ESP32 in the hardware SPI case, use the SPIClass::transferBytes() method when writing instead of looping over individual bytes. 
This makes use of the hardware fifo buffers and is noticeably faster.

c43e0ae83e added write_and_read() 
This method adds a wrapper for transfer() with CS-pin and
transaction management

Update Adafruit_SPIDevice.cpp 
The SPI.cpp that the STM32 project uses does not have a transfer method with both a buffer and a length.  Changes to this file uses a transfer method that just needs a single 8 bit character.
