Hello, I am trying to establish standard CAN communication between the sn65hvd230 IC and the stm32f4 discovery and stm32f103. While the loopback mode works fine, when it sends data to the normal mode, the output goes to 0 and then back to 1. I still haven't found a solution.
Surely easier to cut-n-paste
Running from a 84 MHz bus, perhaps 1 Mbps? 500 kbps at 42 MHz.
Are you sure there's not a better balance of Prescaler, SJW, BS1, BS2 settings?
Perhaps SJW =1, BS1 = 4, BS2 = 2 or SJW =1, BS1 = 5, BS2 = 1
Loopback doesn't need a responding/acknowledging device on the bus, Normal mode does.
