Other Parts Discussed in Thread: HALCOGEN
Hello,
I'm starting with CAN communication in TMS570LS1224, and I searched for some project examples to help me get started.
The three example projects I found are:
1) The TI Hercules CAN tutorial on Youtube:
https://www.youtube.com/watch?v=TrKQN-sor-s&t=252s&ab_channel=TexasInstruments
2) A project example in an E2E thread:
3) The following example installed with HALCoGen:
C:\ti\Hercules\HALCoGen\v04.07.01\examples\TMS570LS12x_11x\example_canCommunication.c
But when I run any one of these projects, the CAN1TX signal waveform is like the one displayed below, which is not a correct CAN communication waveform.
There are only about 15 pulses in the waveform, and the pulse width is incorrect.
P.S. I don't have a transceiver yet, so I'm holding the RX pin at 3.3 V.
How can I solve this problem?
Thanks
