TMS570LC4357: ARINC429 implementation in micrcocontroller

Part Number: TMS570LC4357

Hi,

Can we implement ARINC429 logic in microcontroller?  As per datasheet there is a high end timer interface.  Can this be used or is there any other interface which can support this?

We are planning to implement ARINC429 logic in the controller and use an external transceiver IC to convert it into ARINC levels?

If ARINC429 interface can be supported, what is the impact on processor utilization?

Regards,

Archana Rao

  • Hi Archana,

    As you have correctly identified, the programmable high-end timer can be used to emulate several different serial interfaces such as I2C, UART, EnDAT, etc. This is especially valid for fixed-frame-format interfaces. We do not have an implementation example for ARINC429 that you can readily use as reference. Hence we also do not have any CPU lading information for this implementation. For reference the loading on the main CPU is very minimal for implementing I2C, since the HET acts as an independent coprocessor.

    You can certainly use some of the HET implementation examples as reference and implement your own ARINC429 interface.

    You can use the HET IDE for your development: http://www.ti.com/tool/het_ide
