At90CAN32. How to get rid of Tx Form Error (FERR, FERG) ?
It is in the Bosch CAN 2.0 specification. The AVR data sheet only documents the RC internal oscillator characteristics.Bosch Specification wrote:For the full bus speed range of...

Setting CANGIE = 0x80 makes no sense. You are enabling the CAN IT interrupt (see Figure 16-14 CAN Controller Interrupt Structure) but you are not enabling any CANSTMOB or CANGIT...

Issues receiving CAN signals at90CAN128
You did not say which compiler you are using. This: CANIDT = 0; suggests you are using WinAVR/AVRGCC since CANIDM is a 32 bit value reference. I will assume this is GCC...

Well I actually did find a few bugs in the old test program code. I forgot to re-enable the Rx Remote Frame after the Tx automatic reply Data Frame completes. I got rid of the...

So, did that test program help out, or was it broken?

This comment is not correct since the CANIDM registers are used for CAN Rx: CANIDM1 = CANIDM2 = CANIDM3 = CANIDM4 = 0; // CANIDM is not used for CAN Rx I would...

Any experience with AVR LIN/UART hardware?
Since this subject is about using hardware, you should start a new forum thread about the LIN protocol. People that could read and respond to a LIN protocol question will likely...

The slope control (the MCP2551 RS input pin) is for reducing radiated noise from the CAN bus wires. It limits the slew rate of the CAN bus drivers. Slope control used on a high...

Just noticed another error in the receive CAN node code: CANIDM1 = CANIDM2 = CANIDM3 = CANIDM4 = 0; // CANIDM is not used for CAN Кx This is a Rx MOb and the...
