Fix compiler warning: initialization makes integer from pointer without a cast
Fix #44 Using a uint32_t was a legacy from mbed pinmap feature. This allow to be compatible with high leve api common to all mbed target. There is not reason to keep it for Arduino. Peripheral(SPIx, DACx, TIMx,...) is a pointer so manage it as it is to avoid cast. system/Drivers/CMSIS/Device/ST/STM32F4xx/Include/stm32f429xx.h:1245:29: warning: initialization makes integer from pointer without a cast [-Wint-conversion] #define ADC1 ((ADC_TypeDef *) ADC1_BASE) ^ /local/data/work/stm32/stm32duino/arduino-1.8.3/hardware/STM32/stm32/variants/NUCLEO_F429ZI/PeripheralPins.c:41:13: note: in expansion of macro 'ADC1' {PA0, ADC1, STM_PIN_DATA_EXT(STM_MODE_ANALOG, GPIO_NOPULL, 0, 0, 0)}, // ADC1_IN0 - PA0/WKUP ^~~~ ...
