2-wire potentiometer ADC input protection
Very good point, thanks! I'll had a 100 Ohm before the diode.   EDIT: I've had to increase the above 100 Ohm series resistor to 1000 Ohm in order to balance power rating vs....

2-wire potentiometer ADC input protection
Thanks for the link, that was indeed some very good reading.   I'm still confused about the diode in series with the 1kOhm pullup to 5V. My understanding of these two-wire...

2-wire potentiometer ADC input protection
Thanks again for your input. I've done some more research, and have made a change to the 5V power supply as well. I've replaced the existing regulator with one which has reverse...

SAME70 CAN - Clarifying watermark, put/get indexes and batch processing
It looks like I can potentially answer question 1 myself, as I had a realisation as soon as I had completed the post and was reading through it again. I went into the datasheet...

Difference between SAME70Q21A & SAME70Q21B
Hi Yashwanth,   Since our last correspondence I've now got MCAN0 partially working on the SAME70Q21B. MCAN0 TX is working as expected; I can receive the expected arbitration...
