I have a MSc project in mobile robotics which involves the use of TMS320F2812 DSP and CAN. I would like to setup a test configuration. I compiled example programs from TI but unfortunately there is no signal change on the CAN TX pin. During debugging I noticed, that the program never actually leaves the InitECan function because it gets trapped in a loop waiting for the CCE bit to be set - and this does not happen. Forcing a change with Code Composer lets the program through, but there is no sign of CAN frames. I would be very happy if anyone could help.
have You connetced a transceiver to the CAN-Pins of the CPU and have You wired the CAN-Bus correctly ? Incorrect connection of thee Transceiver as well as a shortcut on the CAn-bus can cause this error.
The CPU has to sense CYNRX high prior able to set the CCE to one. For our systems we had to implement a break inside this loop, because sometimes the system does have a corrupted CAN-bus.
Sta...i'm gaston and i new in the dsp family, i have a ezdsk 28335 and my problem is i can't run a program because i don't know how to make a .cmd, i just want to do a sine wave, i know how to do the c code but de .cmd not. can you help me. Thanks. Gaston.
