XMC4 series Analog Referenece AREF pin errors #199

Closed techpaul closed 1 year ago

techpaul commented 2 years ago

XMC4 series boards

Wiki for XMC4400 and XMC4700 claims on pinout diagram that the AREF pin is

P2.3 Arduino pin 14

AREF is HARDWIRED TO POWER RAILS

P2.3 can be Arduino pin 14, but it is on a DIFFERENT hardware pin most likely RJ45 as the circuit shows this as ETH-RXD1

Please do not copy pin out from XMC4200 or XMC4400 to any new XMC4200 wiki page.

pins_arduino.h for XMC4400 and 4700, claims that ARduino pin 14 is "AREF TO DO:" it is not.

*Manual and Hardware" for XMC4200 and XMC4400 claims R109 is fitted so AREF will give 3V3 as is required needs physical checks as I do not have these boards.

For XMC4700 manual and actual hardware has no R109 so AREF is open circuit where as R109 should be installed.

I will be updating my Wiki on this for hardware at least for pages https://github.com/techpaul/XMC-for-Arduino/wiki/Analog-Functions-and-Additions and https://github.com/techpaul/XMC-for-Arduino/wiki/XMC4xxx-Series-Analog-pins
