Hi,

/ <e> TWI0_ENABLED - Enable TWI0 instance
//==========================================================
#ifndef TWI0_ENABLED
#define TWI0_ENABLED 1
#endif
// <q> TWI0_USE_EASY_DMA - Use EasyDMA (if present)

#ifndef TWI0_USE_EASY_DMA
#define TWI0_USE_EASY_DMA 1
#endif

// </e>

// <e> TWI1_ENABLED - Enable TWI1 instance
//==========================================================
#ifndef TWI1_ENABLED
#define TWI1_ENABLED 1
#endif
// <q> TWI1_USE_EASY_DMA - Use EasyDMA (if present)

It looks like you configured both instances to the same GPIO pins. Check the assigned pins.

Hi there,

I was under the impression only 1 and 2 are available, 0 is used for QSPI?

look forward to an Answer.
