I2C Slave Callback not being called...

[jwoo124]

Hi, this is based on the k3x4evb-t172 board.

I'm trying to use this board as a slave device in order to test transmitting/receiving from this end.

Using channel LPI2C0 as Master and LPI2C1 as the Slave device. I've already tested as the Master device with an EEPROM before this and now using it as a slave device instead.

After searching, I've just made a simple MasterSendData to show the regular transmission between the Master and Slave. I created a SlaveCallback function and added events so that they can be triggered during interrupts. I've used interrupt handler and everything else.

When running the debugger, it doesn't seem to leave the MasterSendData/GetTransfer loop to even hit the callback. 

I was wondering if I was approaching this correctly? I feel like something is always missing..

I thought that approaching this with coding the callback would help me understand how the transmission between the 2 worked, but maybe I'm going about this wrong?

Hi

Which version of S32K3 RTD did you install?
I installed RTD 4.0.0 in S32DS v3.5, and the I2c_Ip_Example_S32K344 project has configured LPI2C1 as interrupt mode and set a Callback (I2c_SlaveCallback). It is recommended to refer to this example.

Best Regards,
Robin

Hi Robin,

I am currently using both S32DS 3.4 and 3.5, RTD 2.0.0 for 3.4 and RTD 2.0.3 for 3.5.

I tried to install RTD 4.0.0 for 3.5 like you suggested; however, after doing so, I still could not find the folder for 4.0.0. It still shows as before. For the I2C_Ip_example you are talking about, is it the one that uses MCAL with the callback function that doesn't specify a Slave Callback, but uses a callback in general?

Please check whether it meet your needs. I am using S32DS v3.5 + S32K3 RTD 4.0.0. 

If you want to install S32K3 RTD 4.0.0, please refer to the discussion in RTD 4.0 with Design Studio 3.5.

Unfortunately, there is no current way to install multiple RTD packages in the same instance, as a workaround, you can install multiple instances for S32DS like:
C:\NXP\S32DS.3.5_RTD300\
C:\NXP\S32DS.3.5_RTD400\
and then install specific RTD to each instance.
