Beispiel #1

Datei: SPI.cpp Projekt: hasnainvirk/mbed-os

void SPI::start_transfer(const void *tx_buffer, int tx_length, void *rx_buffer, int rx_length, unsigned char bit_width, const event_callback_t& callback, int event)
{
    lock_deep_sleep();
    _acquire();
    _callback = callback;
    _irq.callback(&SPI::irq_handler_asynch);
    spi_master_transfer(&_spi, tx_buffer, tx_length, rx_buffer, rx_length, bit_width, _irq.entry(), event , _usage);
}

Beispiel #2

Datei: I2C.cpp Projekt: 0xc0170/mbed

int I2C::transfer(int address, const char *tx_buffer, int tx_length, char *rx_buffer, int rx_length, const event_callback_t &callback, int event, bool repeated)
{
    lock();
    if (i2c_active(&_i2c)) {
        unlock();
        return -1; // transaction ongoing
    }
    lock_deep_sleep();
    aquire();

    _callback = callback;
    int stop = (repeated) ? 0 : 1;
    _irq.callback(&I2C::irq_handler_asynch);
    i2c_transfer_asynch(&_i2c, (void *)tx_buffer, tx_length, (void *)rx_buffer, rx_length, address, stop, _irq.entry(), event, _usage);
    unlock();
    return 0;
