x0 - X postion of 1st point
y0 - Y postion of 1st point
x1 - X postion of 2nd point
y1 - Y postion of 2nd point
color - Color
void drawRect(uint8_t x0, uint8_t y0, uint8_t x1, uint8_t y1, uint16_t color)
Draw a rectangle edge.
x0 - X postion of 1st point
y0 - Y postion of 1st point
x1 - X postion of 2nd point
y1 - Y postion of 2nd point
color - Color
void fillRect(uint8_t x0, uint8_t y0, uint8_t x1, uint8_t y1, uint16_t color)
Draw a filled rectangle.
x0 - X postion of 1st point
y0 - Y postion of 1st point
x1 - X postion of 2nd point
y1 - Y postion of 2nd point
color - Color
void drawCircle(uint8_t x0, uint8_t y0, uint8_t radius, uint16_t color)
Draw a circle.
x0 - X postion of middle point
y0 - Y postion of middle point
radius - Radius
color - Color
uint8_t drawText(uint8_t x, uint8_t y, char *s, uint16_t color, uint16_t bg_color)
Draw a string from RAM. The return value is the X end postion of the text.
x - X postion (left top)
y - Y postion (left top)
s - Pointer to string (RAM)
color - Font color
bg_color - Background color
uint8_t drawTextPGM(uint8_t x, uint8_t y, PGM_P s, uint16_t color, uint16_t bg_color)
Draw a string from Flash. The return value is the X end postion of the text.
x - X postion (left top)
y - Y postion (left top)
s - Pointer to string (Flash)
color - Font color
bg_color - Background color
For colors you can use the RGB(red,green,blue) function.
Examples: clear(RGB(255,50,100))
drawText(10, 10, "Hello world", RGB(0,0,255), RGB(255,50,100))
drawTextPGM(10, 20, PSTR("Hello world"), RGB(0,255,0), RGB(255,50,100))
To rotate or mirror the display uncomment the defines S65_ROTATE or S65_MIRROR in /libraries/S65Display/font_8x12.h.
The text functions can draw characters from 0x20 to 0x7F.
But you can remove the FONT_END7F definition from /libraries/S65Display/font_8x12.h to support 0x20 to 0xFF.
RotaryEncoder
void init(void)
Initialize the microcontroller periphery.
void service(void)
This function has to be called every 1 millisecond (1000 Hz).
int8_t step(void)
Get the step of the rotary encoder: -1, 0, +1
int8_t sw(void)
Get the state of the switch: 0, SW_PRESSED, SW_PRESSEDLONG
SDcard
void init(uint8_t clock_div)
Initialize the microcontroller periphery.
clock_div - SPI clock divider (2, 4, 8, 16, 32), SPI clock = Main clock / clock_div
void service(void);
This function has to be called every 10 milliseconds (100 Hz).
uint8_t mount(void);
Initialize the memory card and mount it.
The return value is 0 if the mounting failed and 1 if card is mounted successfully.
void unmount(void);
Unmount the memory card.
