If data size to be sent is greater than the max defined, application can split the transfert Note: no limit implemented in RX buffer, because when receiving, data are received on I2C, it is not possible to split. Fixes stm32duino#1539 Signed-off-by: Alexandre Bourdiol <[email protected]>
Check of null pointer is already done in both * allocateTxBuffer() * allocateRxBuffer() and it leads to _Error_Handler() Signed-off-by: Alexandre Bourdiol <[email protected]>

Summary
Wire: limit TX buffer size to avoid consuming too much stack
If data size to be sent is greater than the max defined,
application can split the transfert
Note: no limit implemented in RX buffer, because when receiving,
data are received on I2C, it is not possible to split.
Fixes #1539
