Constructor for class for driving TM1638 LED controller as used in LKM1638.
Supports 8 Digits of 7 Segments + DP Icons. Also supports 8 Bi-Color LEDs and a scanned keyboard of 8 keys.
- Parameters:
-
PinName mosi, miso, sclk, cs SPI bus pins
Supports 8 Digits of 7 Segments + DP + Bi-Color LED Icons. Also supports a scanned keyboard of 8.
- Parameters:
-
PinName mosi, miso, sclk, cs SPI bus pins

Member Function Documentation
int _putc | ( | int | value ) | [protected, virtual] |
Write a single character (Stream implementation)
Definition at line 890 of file TM1638.cpp.
void clrIcon | ( | Icon | icon ) |
Clr Icon.
- Parameters:
-
Icon icon Enums Icon has Grid position encoded in 8 MSBs, Icon pattern encoded in 16 LSBs
- Returns:
- none
Definition at line 856 of file TM1638.cpp.
void cls | ( | bool | clrAll = false ) |
Clear the screen and locate to 0.
- Parameters:
-
bool clrAll Clear Icons also (default = false)
Definition at line 811 of file TM1638.cpp.
void cls | ( | ) | [inherited] |
Clear the screen and locate to 0.
Definition at line 69 of file TM1638.cpp.
int columns | ( | ) |
Number of screen columns.
- Parameters:
-
none
- Returns:
- columns
Definition at line 803 of file TM1638.cpp.
bool getKeys | ( | KeyData_t * | keydata ) | [inherited] |
Read keydata block from TM1638.
- Parameters:
-
*keydata Ptr to Array of TM1638_KEY_MEM (=4) bytes for keydata
- Returns:
- bool keypress True when at least one key was pressed
Note: Due to the hardware configuration the TM1638 key matrix scanner will detect multiple keys pressed at same time, but this may result in some spurious keys also being set in keypress data array. It may be best to ignore all keys in those situations. That option is implemented in this method depending on define setting.
