T4.x - Software SPI - don't use FAST_PINIO

Limor "Ladyada" FriedandGitHub b949d28bde Merge pull request #93 from eringerli/cs-transaction-management 
better transaction management
 2022-05-02 18:29:00 -04:00
KurtE 17cf18bf5b T4.x - Software SPI - don't use FAST_PINIO 
The original problem was that the code defined the registers and mask as 8 bits, when the T4.x ones are 32 bits.  So it only worked on a subset of pins.

So first fix would be to simply define these values as 32 bits.  But doing so leaves you code at risk as the Set/Clear code in this library is not atomic,
Example: *clkPort |= clkPinMask;

So if something happens in the small time window after the time the register is retrieved and then manipulated and written back, such as an interrupt.
Or maybe if other hardware is driving the pin.  These changes would be
clobbered by the above code.

Not sure how many other boards (if any) may be hit by the same issue.

It is not an issue with T3.x as the Teensy code uses the M3/M4 bitband support, so for each pin there is a unique memory address for it and these operations are atomic.

Note: the Arm M7 does not support bitbands.  However  in these caseAtomic code can be written for the T4.x by instead using the DR register of the IO port, you use the DR_SET, DR_CLEAR, DR_TOGGLE registers instead which do as the names imply
the do that operation only those pins who have a 1 bit set to the value...

Christian Riggenbach 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.
 2022-05-02 22:37:17 +02:00
Christian Riggenbach 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.
