Hi to all the people in the community
i have an intermediate level when i check ACK bit in an I2C communication ,with uC sending the correct address slave,
It looks like after the 8th bit,the master uC , instead of releasing the SDA line, holds it at high level,in conflict with the acknowledging peripheral
low level , :
Notice that if i use the same pins in GPIO bitbang ,everything works as expected.
I decided to use a MKV31F256VL uController in a prototype needing versatile PWM and good clock speed
I had to communicate via I2C with a RTCC.
I did the same thing in minutes in a previous version using a baseline uC,a MKL15 ,using Code Warrior 10.5,
The PE component for I2C gave me easily the necessary methods.
With this uC i had to use KDS._12C_hal
The GenericI2C component seems not completely implemented for this device.So i tried with a lower level component:fsl_i2C_hal
I used it in a non -OSA project,in a very simple way,not very differently than directly accessing to registers,with no interrupts or semaphores.
The pullup resistors are both 10K.
