libohiboard's Issues

Add/Fix PLL and HSE management on STM32L0

There are a lot of TODO inside clock_STM32L0.c

ADC into low-power

These functions must be added to reduce consumption (by @NicoPaolinelli ):

/*
 * To keep power consumption low, it is important to disable the ADC voltage regulator
 * before entering lowpower mode (LPRun, LPSleep or Stop mode).
 */
void LowPower_disableADCRegulator (void)
{
    if (UTILITY_READ_REGISTER_BIT(ADC1->CR, ADC_CR_ADEN) == 1)
    {
        UTILITY_SET_REGISTER_BIT(ADC1->CR, ADC_CR_ADDIS);
    }
    UTILITY_CLEAR_REGISTER_BIT(ADC1->CR, ADC_CR_ADVREGEN);
}

void LowPower_enableADCRegulator (void)
{
    UTILITY_SET_REGISTER_BIT(ADC1->CR, ADC_CR_ADVREGEN);
    UTILITY_SET_REGISTER_BIT(ADC1->CR, ADC_CR_ADEN);

    while (UTILITY_READ_REGISTER_BIT(ADC1->CR, ADC_ISR_ADRDY) != 1);
    UTILITY_SET_REGISTER_BIT(ADC1->CR, ADC_ISR_ADRDY);
}

Pin management and initialization for FRMD-KL03

This feature allows to use the new library structure with automatic initialization of the pins.

Test libreria

Testare libreria con scheda OHIBoard.
Essendo i moduli USART uguali nelle famiglie K40 e K60, si potrebbe provare anche sulla Kiwistick o sulle board in kit con le Tower che ci sono all'università.

Add LoRa middleware

Baudrate error in kl15

Added rounding up and down for calculation of sbr.

/* Calculate baud settings */
float pre_sbr = (float)clockHz/(baudrate * 16); // per arrotondamento
sbr = (uint16_t)((clockHz)/(baudrate * 16));
    if (pre_sbr-sbr>0.5){
        sbr=sbr+1;
    }
