Hi,

We are developing a display using STM32F439NIH6 Microcontroller in our design. We have the following technical queries:

We have referred to your evaluation board design and we are interfacing STM32F439NIH6 with SDRAM, NVRAM and ARINC 429 devices through FMC data bus and Address bus.

Can we connect all 3 loads and access simultaneously.

We are unable to drive all the three loads. During the process of analysis we came across I/O Cell Compensation in Reference Manual.

Is this can be enabled for FMC?

We are working on 3.3V supply and configured the System Clock as 180MHz.

We tried to enable I/O cell compensation by reducing the System Clock to 100 MHz/90 MHz and 50 MHz.

We are unable to enable the Cell Compensation. Please help us in this regard by providing the procedure to enable the same.

ARINC 429 Interface with STM32 MCU - Help Needed

Dear gajraj,

I hope this message finds you well.

I recently saw your post about interfacing an STM32F439NIH6 with ARINC 429 using the HI-3585 transceiver. I'm currently working on a project that requires a similar interface with an STM32 MCU and HI-3585.

As this is my first experience with ARINC 429, I'm encountering some challenges during configuration. I would be grateful if you could offer any guidance or advice to help me understand and overcome these issues.

Thank you for your time and consideration.
