» CAN-Bus repeating frame problem.
I`m using two AVR AT32UC3C0512C CAN nodes, I get an Atmel-Studio 7 example, the CAN Software Stack Example 2 - UC3C-EK.
The CAN Frames are repeating always 32 times, half of that get ACK. The fault confinement is normal.
How can I get a single-shot transmission?
The problem was a transceiver power supply. I supplied with 3.3V, the final level on Receptor Rx was lower than the minimum needed for a ACK recognise on CANIF os UC3C.
To solve the problem, just use a higher voltage level.
