Serial communication, particularly UART (Universal Asynchronous Receiver\/Transmitter), is a fundamental aspect of embedded systems development. Testing UART communication is crucial to ensure the accuracy and reliability of data transfer in STM32 microcontroller-based projects. In this comprehensive guide, we will take you through the process of testing UART prints on STM32 microcontrollers using Tera Term serial monitor software.<\/span><\/p>\n

 <\/p>\n

Creating the Buffer:<\/strong> <\/span><\/p>\n

To get started, let’s create a buffer named usr_msg<\/code>(Figure 1) in the global space<\/span>. This buffer will serve as our test bed for transmitting messages through UART.<\/span><\/p>\n

char<\/span> usr_msg[250];<\/pre>\n
<\/div>\n
\"Figure
Figure 1. Creation of buffer.<\/span><\/figcaption><\/figure>\n
 <\/p>\n
Next, we’ll populate the usr_msg<\/code> buffer with a sample message using the sprintf<\/code> function.  Let\u2019s do that after the prvSetupHardware function. <\/span><\/span><\/p>\n
The prvSetupHardware is the function that does the UART initialization. Before UART initialization, you can\u2019t print anything. Let\u2019s populate usr-msg with some message by using sprintf, as shown in Figure 2.<\/span><\/p>\n
sprintf<\/span><\/strong>(usr_msg,\"This is hello-world application starting\\n\");<\/pre>\n
\"Figure
Figure 2. Populating usr-msg with some message.<\/span><\/figcaption><\/figure>\n
 <\/p>\n
After that, let\u2019s use the printmsg function and just pass usr_msg buffer as a parameter, as shown in Figure 3. The sprintf copies the given message into the usr_msg buffer, and then we just print that message via printmsg function.<\/span><\/p>\n
printmsg(usr_msg);<\/pre>\n
\"Figure

 <\/p>\n
Testing the Project:<\/strong> <\/span><\/span><\/p>\n
Now, let’s move on to testing our UART communication project.<\/span><\/p>\n
Let\u2019s compile the project (Figure 4). The project builds successfully without any errors.<\/span><\/p>\n
\"Figure
Figure 4. Building the project.<\/span><\/figcaption><\/figure>\n
 <\/p>\n
Now open your serial monitor software. If you are using Windows, then you can use tera term software (Figure 5). If you don\u2019t have this software, just download and install it on your computer. <\/span><\/p>\n
Tera term is a serial monitoring software, which is freely available, and you can download and install it if you haven\u2019t done it already.<\/span><\/p>\n
Let\u2019s open the tera term software. Then establish the serial connection, i.e., our ST-Microelectronics, and click ok (Figure 6).<\/span><\/p>\n
\"Figure
Figure 5. Tera term software.<\/span><\/figcaption><\/figure>\n
 <\/p>\n
\"Figure
Figure 6. Establishing serial connection.<\/span><\/figcaption><\/figure>\n
 <\/p>\n
After that, configure the serial port (Figure 7). Select the baud rate of 115200 because the firmware running on our board uses the same baud rate range. All the settings in Figure 7 should be the same with respect to the code that we have written. Now let\u2019s click ok (Figure 7).<\/span><\/p>\n
\"Figure
Figure 7. Configuring serial port.<\/span><\/figcaption><\/figure>\n
 <\/p>\n
Download the code into the board (Figure 8). Tick the reset after the program (Figure 9) and click ok.<\/span><\/p>\n
\"Figure
Figure 8. Downloading the code.<\/span><\/figcaption><\/figure>\n
 <\/p>\n
\"Figure
Figure 9. Ticking reset after program checkbox.<\/span><\/figcaption><\/figure>\n
 <\/p>\n
Now the board is programmed, and we got the output on the serial monitor software (Figure 10). And you can see that the cursor is at the end of the output. That\u2019s because you can do some settings here.<\/span><\/p>\n
 <\/p>\n
Go to the setup terminal and select receive CR+LF and click ok (Figure 11). Now just reset the board.<\/span><\/p>\n
Troubleshooting:<\/strong><\/span><\/p>\n
    \n
  • Baud Rate Mismatch:<\/strong> Ensure that the baud rate in your code matches the one configured in Tera Term.<\/span><\/li>\n
  • Newline Character:<\/strong> If messages appear on a new line but don’t return to the original position, add a carriage return (\\r<\/code>) in your sprintf<\/code> statement.<\/span><\/li>\n
  • Incomplete Messages:<\/strong> If messages are truncated or incomplete, check the buffer size and make sure it can accommodate your messages.<\/span><\/li>\n<\/ul>\n
     In Figure 12, you can see that it is not working. It actually needs a carriage return. The message has come to the newline since you are sending a newline character at the end of the message (Figure 8). But it did not return to the original position. That\u2019s why you have to send the carriage return, i.e., \\r, as shown in Figure 13.<\/span><\/p>\n
    \"Figure
    Figure 10. Output on the serial monitor software.<\/span><\/figcaption><\/figure>\n
     <\/p>\n
    \"Figure
    Figure 11. Configuring serial port.<\/span><\/figcaption><\/figure>\n
     <\/p>\n
    \"Figure
    Figure 12. Output on the serial monitor software.<\/span><\/figcaption><\/figure>\n
     <\/p>\n
    \"Figure
    Figure 13. Adding carriage return in sprintf statement.<\/span><\/figcaption><\/figure>\n
     <\/p>\n
    Try to build the project once again\u2014the program compiled successfully. Now let\u2019s test the project by downloading it into the chip. Reset your board once again. Now you can see that the result will be fine (Figure 14).<\/span><\/p>\n
