Because of the internal reference of 2.5V on Analogue pins
of ESP32-S2, the R6 must be modified from 20k Ohm to 16.67k Ohm.
This can be achieved by placing a new 100k Ohm resistor
in parallel with R6 resistor. Use this mod only when Arduino
is ESP32-S2 based.
Previously the new line characters were expected to be
part of the feed request message. This is not so on
ESP32 based Arduino library implementation. The new
line characters arrive later on separately after a small
pause This code change fixes 'corrupted feed request'
warning messages on such Arduino platforms.
The IDCODE check mask was updated to support:
ATF1502ASL: 0150203F or 0150303F
ATF1502ASV: 0151203F or 0151303F
ATF1504ASL: 0150403F or 0150503F
ATF1504ASV: 0151403F or 0151503F
The ID codes were found on https://bsdl.info
Previously the TDO pull-up was not properly connected
to VCC. The Rev.2 adapter can still be used, either
without the pull-up or with a small mod-wire to
connect the pull-up with the VCC."
Previously unused pins were always set as output low.
Now, they are output low when active operation is in
progress, and they are set as input when inactive.
When the serial device name is not passed with paramerer -d
then the PC app will try to find an existing serial device.
* On Windows: selects the COM device with the highest number.
* On Linux: selects the serial usb device in any order, but
priority is given to devices with Arduino name.
* ON MAC OS: selects the last /dev/tty.* or /dev/tty/wchusb*
device in the order that OS lists them.
This serial port detection should work OK if you have only one
Arduino attached. If you have (and need to have) several
Arduinos or serial ports connected at the same time then pass
the '-d' parameter to specify which one to use.
The proress bar cusros hiding/revealing sequence was not
compatible with some Windows versions / shells.
This fix removes the escaped sequences and ensures the progress
bar is fully printed at the end of each iteration, which prevents
the visual artefacts caused by the jumping cursor.
This change stores the digi pot indices in the scale 1-255
(previously 1 -128) so the stored values for calibration
are no longer valid after this change is uploaded to Arduino.
Please re-run the full calibration on your Afterburner!
