|
|
<p>The KSDK provides a peripheral driver for the Inter-Integrated Circuit (LPSCI) module of Kinetis devices.</p>
|
|
<p>The LPSCI driver can be split into 2 parts: functional APIs and transactional APIs.</p>
|
|
<p>Functional APIs are feature/property target low level APIs. Functional APIs can be used for the LPSCI initialization/configuration/operation for optimization/customization purpose. Using the functional API requires knowledge of the LPSCI peripheral and how to organize functional APIs to meet the application requirements. All functional APIs use the peripheral base address as the first parameter. The LPSCI functional operation groups provide the functional APIs set.</p>
|
|
<p>The transactional APIs are transaction target high level APIs. Transactional APIs can be used to enable the peripheral quickly and also in the user's application if the code size and performance of transactional APIs can satisfy the user's requirements. If there are special requirements for the code size and performance, see the transactional API implementation and write custom code. All transactional APIs use the lpsci_handle_t as the first parameter. Initialize the handle by calling the LPSCI_CreateHandle() API.</p>
|
|
<p>Transactional APIs support queue feature for both transmit/receive. Whenever the user calls the LPSCI_SendDataIRQ() or LPSCI_ReceiveDataIRQ(), the transfer structure is queued into the internally maintained software queue. The driver automatically continues the transmit/receive if the queue is not empty. When a transfer is finished, the callback is called to inform the user about the completion.</p>
|
|
<p>The LPSCI transactional APIs support the background receive. Provide the ringbuffer address and size while calling the LPSCI_CreateHandle() API. The driver automatically starts receiving the data from the receive buffer into the ringbuffer. When the user makes subsequent calls to the LPSCI_ReceiveDataIRQ(), the driver provides the received data in the ringbuffer for user buffer directly and queues the left buffer into the receive queue.</p>

<p>This function receives data using the interrupt method. This is a non-blocking function which returns without waiting for all data to be received. If the RX ring buffer is used and not empty, the data in ring buffer is copied and the parameter <code>receivedBytes</code> shows how many bytes are copied from the ring buffer. After copying, if the data in ring buffer is not enough to read, the receive request is saved by the LPSCI driver. When new data arrives, the receive request is serviced first. When all data is received, the LPSCI driver notifies the upper layer through a callback function and passes the status parameter <a class="el" href="group__lpsci__driver.html#ggac1d1feb1e13e35beba93e7afce633e16a4d3b44544996f003e9246e4b725e1db3">kStatus_LPSCI_RxIdle</a>. For example, the upper layer needs 10 bytes but there are only 5 bytes in the ring buffer. The 5 bytes are copied to the xfer->data and the function returns with the parameter <code>receivedBytes</code> set to 5. For the remaining 5 bytes, newly arrived data is saved from the xfer->data[5]. When 5 bytes are received, the LPSCI driver notifies the upper layer. If the RX ring buffer is not enabled, this function enables the RX and RX interrupt to receive data to the xfer->data. When all data is received, the upper layer is notified.</p>
