 This is the third tutorial and here you will see how to establish serial communication between the microcontroller and your PC.

 ## Introduction
 
-If you want to visualize the data you read from the sensor on your PC, you can use the _TRACE()_ function: it is basically a _printf()_ during the debugging, but it performs no action when the production code is released. You can use it as normal _printf()_ (it has the same signature). In fact the _printf()_ usage is almost prohibited by our [coding guidelines](Coding-Guidelines).

You can use it as normal _printf()_ (it has the same signature). In fact the _printf()_ usage is almost prohibited by our [coding guidelines](Coding-Guidelines).\
 Everytime you call _TRACE()_ in your code, the output data is redirected to the default serial port of the microcontroller. The default serial port for the STM32F407VG microcontroller is the `USART3` (default value set by Miosix), which corresponds to the GPIOs `PB10` (TX) and `PB11` (RX). The baud rate is by default set to `19200`.
 
 In order to read the _TRACE()_ output you can use a serial to USB adapter and the connections you need are:
-
-| STM32F407VG  | Adapter |
-|--------------|---------|
-| PB10 (TX)    |   RX    |
-| PB11 (RX)    |   TX    |
-| PB13         |   CTS   |
-| PB14         |   RST   |
-| GND          |   GND   |
-
-Make sure you connect at least `RX`, `TX` and `GND` pins.

 If you want to only receive data you can connect only the RX pin of the adapter (or TX if you only want to send data).
 
 Consider that you should set your serial adapter to work with 3.3 volts, since the microcontroller GPIOs work with this voltage level.

 You also need a program that is able to read those data from the USB port of your PC. You can use for example _GTKTerm_ on Linux or _Putty_ on Windows. You have to select the correct serial port (for example `/dev/ttyUSB0`) and set the correct baud rate.
 
 #### Note
+
 Consider that if you are using a different board, it may be possible that its USB connector is also connected to a microcontroller's serial port (i.e. you don't need to connect an external adapter). Just check which serial port is connected to the USB connector (e.g. `USARTX`).
 
 ## Create your entrypoint
 
-Here we will write an entrypoint that uses the _TRACE()_ function in order to send data to the PC.
-In `src/entrypoints` add a file called `hello-skyward.cpp`.

 In order for the _TRACE()_ function to act as a normal _printf()_, we need to compile the entrypoint with debug enabled. To enable debug you can add the option `-d` when you build with the SBS script:
