0.5.6 --- * Fix for Issue #63 where re-setting up a pin wasn't lining up with RPi.GPIO standards. Calling setup after the first time will now update direction. * README updates to point out the direction() function since that was missing

0.5.5 --- * Fix for Issue #62 where using alternate name of an XIO would cause a segfault due to trying to set pull up/down resistor setting

0.5.4 --- * Re-enabled the polarity setting for PWM based upon Issue #61 * Fixed a 1 letter bug was trying to write inverted to polarity when it wants inversed (such facepalm) * Cleaned up the polarity setting code to work when PWM is not enabled * Fixed the unit test for pwm to verify we can set polarity

0.5.3 --- * Fixes to the PWM pytest * Added pytest for LRADC and Utilities * Makefile updates for all the things

0.5.2 --- * Updating Utilties to determine CHIP Pro better * Updating the README to fix things

0.5.0 --- * CHIP Pro Support * README Updates

0.4.0 --- * Software Servo code added

  • Only works on the LCD and CSI pins
  • Fixed cleanup() for the SOFTPWM and SERVO - The per pin cleanup for SOFTPWM doesn't work as stop() clears up the memory for the pin used - SERVO code was based on SOFTPWM, so it inherited this issue

0.3.5 --- * Merged in brettcvz's code to read a byte of data from the GPIO

  • Cleaned the code up and expanded it (in the low level C code) to read up to 32 bits of data
  • Presented 8 bit and 16 bits of data functions to the Python interface with brettcvz's read_byte() and my read_word()
  • I think I finally fixed the GPIO.cleanup() code one and for all

0.3.4.1 --- * Quick fix as I borked XIO setup as inputs with the latest change that enabled PUD

0.3.4 --- * Pull Up/Pull Down resistor setting now available for the R8 GPIO. * Some general cleanup

0.3.3

  • Added Debug printing for all the capabilities with the toggle_debug() function
  • Added 2 functions from @streamnsight for PWM that allow for setting the period of the PWM and the Pulse Width, both in nanoseconds
  • Fixed the SPI2 overlay stuff by using the NTC overlay instead of mine.

0.3.2

  • Fixing issue #53 to handle the return values of the set functions in pwm_enable.
  • Start of whole library debug for #55

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
