Teensy 3.0 and above support is needed about adafruit-pcd8544-nokia-5110-lcd-library HOT 5 CLOSED

It worked after editing the header file (H file). After changing "uint32_t" in these lines
#else
typedef volatile uint32_t PortReg; ///< PortReg for other chips
typedef uint32_t PortMask; ///< PortMask for other chips
#endif

Changed to "uint8_t"
#else
typedef volatile uint8_t PortReg; ///< PortReg for other chips
typedef uint8_t PortMask; ///< PortMask for other chips
#endif

I request you to update the library by providing the support for Teensy 3.0 and above boards

Thanks

By default the example uses software SPI, switching to hardware SPI should fix it.

The port registers on the Teensy 3 are emulated as 8-bit for compatibility with Arduino so we could check for that board and use the 8-bit defines. The actual port registers for the teensy are 32-bit and can be used directly, that would be the better way to handle it. See this teensy forum post and this one for more info.

Okay, thanks.

Same problem here. Applying @vamsee227 corrections worked!
An update to the library to automatically account for 32 bit Teensies would be nice indeed!

Like:

#if defined(SAM3X8E) || defined(ARDUINO_ARCH_SAMD)
typedef volatile RwReg PortReg; ///< PortReg for SAMD
typedef uint32_t PortMask; ///< PortMask for SAMD
#elif defined(AVR) || defined (TEENSYDUINO)
typedef volatile uint8_t PortReg; ///< PortReg for AVR
typedef uint8_t PortMask; ///< PortMask for AVR
#else
typedef volatile uint32_t PortReg; ///< PortReg for other chips
typedef uint32_t PortMask; ///< PortMask for other chips
#endif

this should be fixed now with the move to busio!
