TMS320F280049C: F280049C AMIC110

Part Number:TMS320F280049COther Parts Discussed in Thread: TIDA-00299, AMIC110, LAUNCHXL-F280049C, TMDXICE110, LAUNCHXL-F28069M

LAUNCH PAD  TMS320F280049C能否与TIDA-00299相接实现EtherCAT通讯?如果可以的话该如何实现,F280049C和AMIC110谁作从站主控芯片?

Susan Yang:

您可以参考下面的技术文章

四,联合C2000 LaunchPAD进行SPI通信测试

其实大概的方式我了解一些,c2000作从站主控芯片,但是官方给的套板举例所用MCU全部带有MAC功能,所以我想知道的是没有MAC+PHY模块的F280049C是否可以作主控芯片,

如果可以的话是不是只需要SPI或者UART任意一种通讯方式连接AMIC110,ECAT信号的ECAT_LATCH0、ECAT_LATCH1、ECAT_SYNC0、ECAT_SYNC2、IRQ、LOADED是否不需要连接;

还是说需要一种通讯加上普通GPIO连接ECAT的6个信号就可以?

主要纠结的问题是ECAT信号的ECAT_LATCH0、ECAT_LATCH1、ECAT_SYNC0、ECAT_SYNC2、IRQ、LOADED连接是普通GPIO还是需要特定外设

理论上是可以的

For richer HMI or broader communications support, especially for very flexible support of industrial Ethernet standards like EtherCAT and Profinet, you can use the F28004x SPI port to communicate with TI’s SitaraTm AMIC110 multiprotocol processors.

我会在确认后给您回复

zhi pan:

万分感谢!

zhi pan:

请问大佬实现方式有思路了吗?期待您的回复。

Susan Yang:

我去找国外同事确认了,因为时差原因,应该要明天有结果

Susan Yang:

请您参考下面的回复:

We don't have a document or software specifically for F280049C + AMIC110. Hardware wise, the LAUNCHXL-F280049C should work with the TMDXICE110 since I believe only a SPI connection is required. Other signals mentioned could be optional depending on the application and need for eCAT SYNC/LATCH signals.

You might find some useful information in the training videos below, which shows LAUNCHXL-F28069M and TMDXICE110 being used together. SW support may be available in one of the processor SDKs.

By the way, any reason you are not looking at the F2838x device which has the EtherCAT slave controller IP integrated into the device?
