<div style="margin-left: 40px;"><span style="font-size: 10pt; font-family: "Verdana","sans-serif"; color: black;">The
STSW-STLKT01 firmware package for SensorTile provides example projects
that can be used as a simple starting point for the development of
custom applications. Built on STM32Cube software technology it includes all the low level
drivers to manage the on-board devices and system-level interfaces.</span><br>
<span style="font-size: 10pt; font-family: "Verdana","sans-serif"; color: black;">
<br>The package comes with 3 applications: DataLog, AudioLoop and BLE_SampelApp.<br>
DataLog application has two major features: sensor raw data streaming
via USB (Virtual COM Port class) and sensor data storage on SD card.<br>
AudioLoop
application sends audio signals acquired by the microphone to an
onboard DAC via I2S interface. In this way the user can conveniently
play the recorded sound on loudspeakers or headphones.<br>
The BLE_SampleApp provides an example of Bluetooth Low Energy
configuration that enables SensorTile to stream environmental sensors
data; it is compatible with ST BlueMS app available for both Android
and iOS.<br>
This firmware package includes Components Device Drivers, Board Support
Package and example applications for the SensorTile platform
(STEVAL-STLKT01V1).<br>

</span><span style="font-size: 10pt; font-family: "Verdana","sans-serif"; color: black;">software
features:<br>
<br>
<br>
<b>Datalog Application</b><br>
<br>
Datalog Application has two operating modes that can be selected at
compile time by changing the value of "SendOverUSB" variable in main.c:<br>
<ul>
<li>SendOverUSB=1 sensor raw data streaming via USB
(Virtual COM Port class) </li>
<li>SendOverUSB=0 sensor raw data storage on SD card. </li>
</ul>
<br>
After reset, the firmware performs the following actions:
<ul>
<li>Configures HAL and clocks. </li>
<li>Configures LED1 (USB mode only) </li>
<li>Configures the Real Time Clock (RTC) </li>
<li>Initializes the USB peripheral or the SPI for SD Card
access </li>
<li>Initializes and enables all the sensors </li>
</ul>
<br>
The main loop is executed every DATA_PERIOD_MS milliseconds
(default=100ms);
<ul>
<li>Reads the timestamp from RTC and writes it to the USB
or SDCard </li>
<li>Reads each one of the configured sensors and writes
the data to the USB or SDCard </li>
</ul>
<br>
If SDCard card mode has been selected, the user must activate the
DataLog with double tap on the board. When the first double tap is
detected the application starts logging data to file
(SensorTile_Log_N000.tsv), another double tap will stop the
acquisition. The user can now repeat the operations and restart the
data logging on another file (SensorTile_Log_N001.tsv).<br>
<br>
<br>
<b>AudioLoop Application</b><br>
<br>
AudioLoop application sends audio signals acquired by the microphone to
the onboard DAC via SAI interface, in this way the user can play the
sound on loudspeakers/headphones.<br>
After reset the firmware performs the following actions:
<ul>
<li>Configures HAL and clocks </li>
<li>Configures LED1 </li>
<li>Configure STM32 Serial Audio Interface peripheral
(SAI) in I2S mode and the external DAC </li>
<li>Configure the digital filter peripheral (DFSDM) for
microphone acquisition </li>
<li>BSP_AUDIO_IN_ClockConfig function (defined weak in
the BSP) is redefined as an empty function in main.c because the clock
and PLLs configuration is already performed in BSP_AUDIO_OUT_Init
function. </li>
<li>Starts the Audio acquisition </li>
</ul>
<br>
The main loop is empty in this application, because all the operations
needed to copy the audio stream acquired from the microphone to the
Serial Audio Interface are executed in the DFSDM interrupt. For this
reason the function AudioProcess() is called by the two callbacks
BSP_AUDIO_IN_TransferComplete_CallBack() and
BSP_AUDIO_IN_HalfTransfer_CallBack().<br>
<br>
<span style="font-weight: bold;">BLE_SampleApp Application</span><br>
<br>
BLE_SampleApp provides an example of Bluetooth Low Energy configuration
that enables SensorTile to stream environmental sensors data; it is
compatible with ST BlueMS app available for both Android and iOS.<br>
<br>
After reset the firmware performs the following actions:<br>
</span>
<ul>
<li><span style="font-size: 10pt; font-family: "Verdana","sans-serif"; color: black;">Configure HAL and clocks</span></li>
<li><span style="font-size: 10pt; font-family: "Verdana","sans-serif"; color: black;">Configure and disable sensors Chip Select pins</span></li>
