Unused variable warning in SAMD51 implementation #359

Open IanBurwell opened 1 year ago

IanBurwell commented 1 year ago

When compiling for the PyPortal (SAMD51) GCC raises an unused variable warning (see below). This issue is not critical but would be easily fixed by removing the hanging bit variable here

GCC (9.3.1) warns the following:

.pio/libdeps/adafruit_pyportal_m4_titano/Adafruit NeoPixel/Adafruit_NeoPixel.cpp: In member function 'void Adafruit_NeoPixel::show()':
.pio/libdeps/adafruit_pyportal_m4_titano/Adafruit NeoPixel/Adafruit_NeoPixel.cpp:2505:44: warning: unused variable 'bit' [-Wunused-variable]
 2505 |   uint8_t *ptr, *end, p, bitMask, portNum, bit;
      |                                            ^~~
