-                        ##### How to use this driver #####
-  ==============================================================================
-    [..]
-      The SPI HAL driver can be used as follows:
-
-      (#) Declare a SPI_HandleTypeDef handle structure, for example:
-          SPI_HandleTypeDef  hspi;
-
-      (#)Initialize the SPI low level resources by implementing the HAL_SPI_MspInit() API:
-          (##) Enable the SPIx interface clock
-          (##) SPI pins configuration
-              (+++) Enable the clock for the SPI GPIOs
-              (+++) Configure these SPI pins as alternate function push-pull
-          (##) NVIC configuration if you need to use interrupt process
-              (+++) Configure the SPIx interrupt priority
-              (+++) Enable the NVIC SPI IRQ handle
-          (##) DMA Configuration if you need to use DMA process
-              (+++) Declare a DMA_HandleTypeDef handle structure for the transmit or receive Stream/Channel
-              (+++) Enable the DMAx clock
-              (+++) Configure the DMA handle parameters
-              (+++) Configure the DMA Tx or Rx Stream/Channel
-              (+++) Associate the initialized hdma_tx(or _rx)  handle to the hspi DMA Tx or Rx handle
-              (+++) Configure the priority and enable the NVIC for the transfer complete interrupt on the DMA Tx or Rx Stream/Channel
-
-      (#) Program the Mode, BidirectionalMode , Data size, Baudrate Prescaler, NSS
-          management, Clock polarity and phase, FirstBit and CRC configuration in the hspi Init structure.

-       Callback registration:
-
-      (#) The compilation flag USE_HAL_SPI_REGISTER_CALLBACKS when set to 1U
-          allows the user to configure dynamically the driver callbacks.
-          Use Functions HAL_SPI_RegisterCallback() to register an interrupt callback.
-
-          Function HAL_SPI_RegisterCallback() allows to register following callbacks:
-            (++) TxCpltCallback        : SPI Tx Completed callback
-            (++) RxCpltCallback        : SPI Rx Completed callback
-            (++) TxRxCpltCallback      : SPI TxRx Completed callback
-            (++) TxHalfCpltCallback    : SPI Tx Half Completed callback
-            (++) RxHalfCpltCallback    : SPI Rx Half Completed callback
-            (++) TxRxHalfCpltCallback  : SPI TxRx Half Completed callback
-            (++) ErrorCallback         : SPI Error callback
-            (++) AbortCpltCallback     : SPI Abort callback
-            (++) MspInitCallback       : SPI Msp Init callback
-            (++) MspDeInitCallback     : SPI Msp DeInit callback
-          This function takes as parameters the HAL peripheral handle, the Callback ID
-          and a pointer to the user callback function.
-
-
-      (#) Use function HAL_SPI_UnRegisterCallback to reset a callback to the default
-          weak function.
-          HAL_SPI_UnRegisterCallback takes as parameters the HAL peripheral handle,
-          and the Callback ID.
-          This function allows to reset following callbacks:
-            (++) TxCpltCallback        : SPI Tx Completed callback
-            (++) RxCpltCallback        : SPI Rx Completed callback
-            (++) TxRxCpltCallback      : SPI TxRx Completed callback
-            (++) TxHalfCpltCallback    : SPI Tx Half Completed callback
-            (++) RxHalfCpltCallback    : SPI Rx Half Completed callback
-            (++) TxRxHalfCpltCallback  : SPI TxRx Half Completed callback
-            (++) ErrorCallback         : SPI Error callback
-            (++) AbortCpltCallback     : SPI Abort callback
-            (++) MspInitCallback       : SPI Msp Init callback
-            (++) MspDeInitCallback     : SPI Msp DeInit callback
-
-       [..]
-       By default, after the HAL_SPI_Init() and when the state is HAL_SPI_STATE_RESET
-       all callbacks are set to the corresponding weak functions:
-       examples HAL_SPI_MasterTxCpltCallback(), HAL_SPI_MasterRxCpltCallback().
-       Exception done for MspInit and MspDeInit functions that are
-       reset to the legacy weak functions in the HAL_SPI_Init()/ HAL_SPI_DeInit() only when
-       these callbacks are null (not registered beforehand).
-       If MspInit or MspDeInit are not null, the HAL_SPI_Init()/ HAL_SPI_DeInit()
-       keep and use the user MspInit/MspDeInit callbacks (registered beforehand) whatever the state.
-
-       [..]
-       Callbacks can be registered/unregistered in HAL_SPI_STATE_READY state only.
-       Exception done MspInit/MspDeInit functions that can be registered/unregistered
-       in HAL_SPI_STATE_READY or HAL_SPI_STATE_RESET state,
-       thus registered (user) MspInit/DeInit callbacks can be used during the Init/DeInit.
-       Then, the user first registers the MspInit/MspDeInit user callbacks
-       using HAL_SPI_RegisterCallback() before calling HAL_SPI_DeInit()
-       or HAL_SPI_Init() function.
-
-       [..]
-       When the compilation define USE_HAL_PPP_REGISTER_CALLBACKS is set to 0 or
-       not defined, the callback registering feature is not available
-       and weak (surcharged) callbacks are used.

- [..]
-    This subsection provides a set of functions allowing to manage the SPI
-    data transfers.
-
-    [..] The SPI supports master and slave mode :
-
-    (#) There are two modes of transfer:
-       (++) Blocking mode: The communication is performed in polling mode.
-            The HAL status of all data processing is returned by the same function
-            after finishing transfer.
-       (++) No-Blocking mode: The communication is performed using Interrupts
-            or DMA, These APIs return the HAL status.
-            The end of the data processing will be indicated through the
-            dedicated SPI IRQ when using Interrupt mode or the DMA IRQ when
-            using DMA mode.
-            The HAL_SPI_TxCpltCallback(), HAL_SPI_RxCpltCallback() and HAL_SPI_TxRxCpltCallback() user callbacks
-            will be executed respectively at the end of the transmit or Receive process
-            The HAL_SPI_ErrorCallback()user callback will be executed when a communication error is detected
-
-    (#) APIs provided for these 2 transfer modes (Blocking mode or Non blocking mode using either Interrupt or DMA)
-        exist for 1Line (simplex) and 2Lines (full duplex) modes.

+# STM32 CAN Demo
+
+This Project is a simple CAN Demo for STM32F407. It uses sta-core, rtos2-utils and TACOS.
+
+## Explanation
+
+In the `startup.cpp` we register threads in the `onManagerInit()` func, by calling the following:
+```c++
+// Register Spam Thread to only run in the first state
+addThread<demo::CanSpam>({ALL_STATES}, 0x123);
+// Register Receive Thread to run in states 0 and 2
+addThread<demo::CanReceiver>({0,2}, 0x124);
+```
+
+The `CanSpam` thread sends a message every 1 second, while the `CanReceiver` thread receives messages and prints them to the console.
+Sending is done by calling the following:
+```c++
+CanSysMsg msg;
+
+msg.paylod = ...;               // Set the payload
+msg.header.sid = getCanID();    // Use the ID of the thread
+msg.header.format = 0;          // Set the format to standard id
+
+sta::tacos::queueCanBusMsg(msg, 0); // Send the message, 0 means no timeout
+```
+
+As we can see here every task has a unique ID, which is used to identify the task. Trough this ID (which is set at construction), messages are automagically forwarded to the correct task.
+
+Receiving is done by calling the following:
+```c++
+CanSysMsg msg;
+if (CAN_queue_.get(&msg, osWaitForever))
+{
+    // use msg.payload and msg.header to access the data
+}
+```
+
+# Setup
+The only thing one must change outside of the App repository (and ofc the including of the Libs) is starting the ALPAKA stack in Core/freertos.c:
+
+```c++
+void StartDefaultTask(void *argument)
+{
+  /* USER CODE BEGIN StartDefaultTask */
+  /* Infinite loop */
+
+	extern void startALPAKA(void *);
+	startALPAKA(argument);
+  for(;;)
+  {
+    osDelay(1);
+  }
+  /* USER CODE END StartDefaultTask */

+## Notes
+
+We are using one of our own "ASEAG" modules which have a special define in the `config.hpp` to indicate the CAN bus and UART output. To replicate this for other hardware one must define `STA_STM32_USART_HANDLE` and `STA_STM32_CAN_HANDLE` in the `config.hpp` file.
