Resolved! Proper way to code in C++, as IOC tool won't update main.cpp but rather create a new main.c

Hey everyone,I'm trying to make a project in C++. I tried the trick to rename main.c to main.cpp with the right-click > rename function. It works, but then if I change the IOC with the config tool, it will create a new main.c with the proper settings...

Hello. How can I measure the length of an indefinite length "uint8_t"? I used sizeof() but it didn't measure correctly

I am using STM32F7 series. I created httpd server ethernet project. I have web code which html,css,js. But my microcontrollers memory not enough for these codes. I need to use SD Card.

I need to put it my web codes (html, css, js) to SD Card. Also These codes need to work on SD Card. Because my web codes memory size is around 300MB. Normally I worked my code (basic html files) without SD Card. It needs converting to fsdata.c files....

Hello, is there a way to calculate and display the flash/memory checksum after build for example in MPLAB X IDE there is a checksum in the dashboard (see the attached picture).

USART2_IRQHandler called continuously for DMA reception on STM32L031K6T6 with hardware flow control

Hi. I am using UART with DMA for TX and RX on STM32L031. It communicates with nRF52833 over UART with hwfc enabled. My problem is, when I receive data from nRF52, USART2_IRQHandler is called continuously. Below is the screenshot of all the flags that...

Resolved! How do I get GDB debug output to a file?

I'm debugging a problem on the target. The data I want to examine is in an array and can be easily seen in the Debugger console using "print output_data". I'd like this in a file to facilitate further host processing. When using gdb standalone I c...

Resolved! How can I know where a function is being used in STM32CubeIDE?

When I analyze a code that another guy made, I want to track where a function is used.I can see the definition of a function using open declaration but I cannot see where the function is used.STM32 has so many files. So, I cannot search for each of t...

X-CUBE-CELLULAR 5.2.x MQTT Client Sample, does not work when using STM32CubeIDE based on GCC.

Instead, the project under IDE_Mqtt folder of X-CUBE-CELLULAR 5.2.x work fine, because it uses IAR Compiler and Embedded Workbench IDE (downloaded under 30day evaluation). The sample code provided, I was able to test it using Stackhero Node-RED Dashb...
