A few years ago I read about voltage spikes in car power lines.

As far as I remember, those spikes come from devices which have an inductance.
They can have peak voltages of more than 100V.

Make sure not only to protect the ADC input but also use a proper power supply for the chip.

Hmm. I knew that pin and pad mean the same thing but I thought that is because the gpio fabric has a pad for bonding on the chip. The fact that some packages have pads instead of pins makes much more sense though

Nice. Yes, critical sections might make sense. You only need to temporarily deactivate the TX interrupt so no need to disable global interrupts.

PS : you might to want to compare tbs against a value or use TCS. Simply for clean code if people use your snippet.

You also might want to try placing the application in the ISR. This is the fastest yet nastiest solution. You might mess up the complete timing behavior of the chip or experience stack overflows. But hey, it would be very fast

Not waking an activated Task in the RX ISR is on purpose. Adding an entry to a queue will set the waiting tasks into READY state. However, there will be no task switch, the RUNNING task stays running. We need a rescheduling point (Yield) to switch tasks. You will find rescheduling points e.g. in the...

Cool !
Thanks

Lines of code != number of instructions. The code looks different but does the same. As u8 is an array you can use the same syntax like you did in your example. As Rudi says: i do the msg_frame example with a typedef struct it is one line :lol: Using a structure that holds all the information necess...

Correct. There is some acknowledgement/error check story going on in the ACK slot of the frame. You should get CAN error IRQs if there is no recipent. Haven't tested it.
