Using more than 2 TPDO

[Alrick-gr]

Hello,
When I m using more thant 2 TPDOs (configured with the OD_editor), the 2 first TPDOs are sent and then, nothing happens.
In CO_CANsend I have the error CO_ERROR_TX_OVERFLOW. If i only use 2 TPDOs, it works perfectly.

When i put a breakpoint before CO_process_TPDO, then it works and send all TPDOS, but the device will no longer receive any commands.



Here you can see the configuration in the OD_editor. If i check "invalid" for one TPDO it works fine

Probably there is a problem with the driver.

Hi!
I have the same issue. I want to send 5 TPDO, and the TPDO1~TPDO4 were sent successfully，but the TPDO5 is not being sent. When I put a breakpoint in CO_TPDOsend(TPDO) .It running normal.When I put a printf or delay before this function, it's also running normal.By the way, I reference to this author's code: https://github.com/CANopenNode/CanOpenSTM32

I forgot to update the issue but i solved my problem by changing the size of the heap and stack.
Also i changed the timing in the function CO_process_TPDO.
And now it works perfectly.
