C++ (Cpp) HAL_USB_USART_Available_Data Examples

Example #1

int32_t HAL_USB_USART_Receive_Data(HAL_USB_USART_Serial serial, uint8_t peek)
{
    if (HAL_USB_USART_Available_Data(serial) > 0)
    {
        int state = HAL_disable_irq();
        uint8_t data = usbUsartMap[serial].data->rx_buffer[usbUsartMap[serial].data->rx_buffer_tail];
        if (!peek) {
            usbUsartMap[serial].data->rx_buffer_tail = ring_wrap(usbUsartMap[serial].data->rx_buffer_length,
                                                                 usbUsartMap[serial].data->rx_buffer_tail + 1);
        }
        HAL_enable_irq(state);
        return data;
    }
