I made a project using fsl_i2c_edma on a k22.
The project works except when i send 1 data byte through i2c, the callback never happened.
I read later in the file fsl_i2c_edma.c :
If transfer size is 1, use polling method
I don't understand why, can someone explain me ?
And, is it possible anyway to use the callback; stay in "standart" edma operation ?
SDK FRDM_K22F 2.6.0
Based on the example project "i2c_edma_b2b_transfer_master"
Thanks in advance.
