Posted on September 20, 2016 at 20:29 During evaluation of this chip, we found thatthe microcontroller apparently sets the ACK bittoo early when receiving messages from other devices. Bus was 250 KBaud with a sample point of 80% (also tried 75% a...
Posted on September 26, 2016 at 17:50Ok the problem is apparently resolved. The project was set up to use the internal oscillator. ST recommended using the external oscillator. When this was done, the problem was resolved.
Posted on September 22, 2016 at 16:31 That is correct. We believe this to be a new errata. We were unable to find any register that would effect the timing of the ACK bit alone. The register settings should affect all bits equally. Do you agree? ...
Posted on September 21, 2016 at 20:08Thank you Hannibal for your response. Unfortunately the only baud rate we will ever use is 250K. That is the J1939 standard. Even if it works at a different baud rate, it will be unusable for our purposes. We...
