0.3.1

  • Fixing issue #50 where I broke GPIO.cleanup() and SOFTPWM.cleanup() when no input is specified.

0.3.0

  • Added setmode() function for GPIO to maintain compatibility with Raspberry Pi scripts, this function literally does nothing
  • Added per pin cleanup functionality for GPIO and SoftPWM so you can unexport a pin without unexporting every pin
  • Updated README to make edge detection wording a little better and to add the per pin cleanup code
  • Version update since I blasted through 3 issues on github and feel like we need a nice bump to 0.3

0.2.7

  • Fix to the Enable 1.8V Pin code as it wasn't working due to bit shifting isn't allowed on a float.
  • Updated README to denote the PocketCHIP Pin names better

0.2.6

  • Fix to keep the GPIO value file open until the pin is unexported (issue #34)

0.2.5

  • Updates to the pytest code for HWPWM and SoftPWM
  • Removed the i2c-1 load/unload support in OverlayManager as CHIP Kernel 4.4.13 has that bus brought back by default

0.2.4

  • HW PWM Fixed - Start/Stop/Duty Cycle/Frequency settings work - Polarity cannot be changed, so don't bother setting it to 1 in start()
  • Added the unexport_all() function to Utilites

0.2.3

  • LRADC Support

  • Added Utilities - Enable/Disable the 1.8V Pin - Change 1.8V Pin to output either 2.0V, 2.6V, or 3.3V

    (Current limited to 50mA)

0.2.2

  • Fixes for Issue #16 - Pass SoftPWM setup errors to Python layer (aninternetof) - Updated spwmtest.py to test for this issue

0.2.1

  • Pull request #12 fixes:
  • Fixed indent in the i2c-1 dts
  • Removed import dependencies in the SPI and PWM overlays
  • Re-enabled building of the dtbo on setup.py install

0.2.0

  • Added the ability to load DTB Overlays from within CHIP_IO
  • Support for PWM0, SPI2, and I2C-1 (which comes back as i2c-3 on the 4.4 CHIP
  • Support for a custom DTB Overlay
  • Fixes to the pwm unit test, all but 2 now pass :)

0.1.2

  • SoftPWM Fix by aninternetof
  • Added a verification test for SoftPWM

0.1.1

  • Some refactoring of the edge detection code, made it function better
  • Added Rising and Both edge detection tests to gptest.py - Small issue with both edge triggering double pumping on first callback hit

0.1.0

  • Fixed edge detection code, will trigger proper for callbacks now

0.0.9

  • Fixed SoftPWM segfault
  • Added Alternate Names for the GPIOs

0.0.8

  • Updates to handle the 4.4 kernel CHIPs. Numerous fixes to fix code issues.
  • Added ability to get the XIO base into Python.
  • Still need a proper overlay for Hardware PWM and SPI.

0.0.7

  • GPIO edge detection expanded to include AP-EINT1 and AP-EINT3 as those are the only other pins that support edge detection

0.0.6

  • Initial PWM
  • GPIO edge detection and callback for XIO-P0 to XIO-P7 working

0.0.4

  • Initial Commit
  • GPIO working - untested callback and edge detection
  • Initial GPIO unit tests
