## Building and flashing
|
|
|
|
|
Just as with normal Arduino codes, build and flash it from the Arduino Software.
|
|
|
|
|
* Board: Generic STM32F103C series
|
|
|
|
|
* Variant: STM32F103C8 (20K RAM. 64K Flash)
|
|
|
|
|
* CPU Speed: 72MHz
|
|

## Note
|
|
|
|
|
If using a different board, then change the configuration and modify the pins accordingly.
|
|
|
|
|
For the STM32 board the following changes are necessary:
|
|
|
|
|
|
|
|
|
|
Adafruit_PCD8544.h:
|
|
|
|
|
```
|
|
|
|
|
#define PCD8544_SPI_CLOCK_DIV SPI_CLOCK_DIV4 -> #define PCD8544_SPI_CLOCK_DIV SPI_CLOCK_DIV8
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
```
|
|
|
|
|
#ifdef __SAM3X8E__
|
|
|
|
|
typedef volatile RwReg PortReg;
|
|
|
|
|
typedef uint8_t PortMask; -> typedef uint32_t PortMask;
|
|
|
|
|
#else
|
|
|
|
|
typedef volatile uint32_t PortReg;
|
|
|
|
|
typedef uint8_t PortMask; -> typedef uint32_t PortMask;
|
|
|
|
|
#endif
|
|
|
|
|
```
