TMDSCNCD263: Method to send information from TMDSCNCD263 to a motherboard

user5008585

Part Number: TMDSCNCD263

I want to make a protocol to send data of 100Byte from TMDSCNCD263 to a motherboard every 0.1 msec, but please tell me what kind of code I should make because there is not knowledge.

I use ethernet for connection of TMDSCNCD263 and a motherboard.

(I confirmed movement with reference to the following sample, but do not get the connection confirmation.)

Hi There,

EtherCat can be a good candidate. The sync time between the EtherCat Master and Slave can be 62.5us. 125us or 250us.

See AM263x MCU+ SDK: EtherCAT Slave Beckhoff SSC Demo (ti.com) for details.

Best regards,

Ming

Hi Ming

Thank you for telling information.

>The sync time between the EtherCat Master and Slave can be 62.5us. 125us or 250us.

Does it mean that I cannot send data every 0.1 msec?

Best regards.

Hi There,

The goal during development of EtherCAT was to apply Ethernet for automation applications requiring short data update times (also called cycle times; ≤ 100 μs) with low communication jitter (for precise synchronization purposes; ≤ 1 μs) and reduced hardware costs.

It is typical for a transfer of 125 byte over 100Mbit/s Ethernet and can be updated with up to 10 kHz. Typical network update rates are 1–30 kHz, but EtherCAT can be used with slower cycle times.

The sending data every 0.1ms is at 10Khz, so it is possible.

Best regards,

Ming

Hi Ming,

Thank you.
I understood that a function could be realized.

With reference to a sample cord, I make a code.

best regards.
