Unicode overflow: It creates a buffer overflow by inserting unicode characters into an input that expects ASCII characters. ASCII and unicode are encoding standards that let computers represent text. Because there are so many more characters available in unicode, many unicode characters are larger than...
As you may have noticed, we used the first address of the memory to store the BTABLE, which is a list of addresses of the endpoint buffers. The BTABLE stores 8 bytes for each endpoint. Since the STM32G474 has 8 endpoints, it can consume at maximum of 64 bytes. In th...
(char*)ptr + 1), it will advance the pointer 1 byte, because a "char" is 1 byte. The code ((void*)ptr + 1) does not work, because the compiler has no idea what size "void" is, and therefore doesn't know how many bytes to add. This is why you got Error 1 C2036, from ...

You can edit the run-time parameters for many of the Device Fundamentals tests. In the Driver Test Group window, an arrow (») next to a test name indicates that the test has parameters that you can change. Select the arrow (») to display the run-time parameters. ...
The thing is that now, when I try to convert the string to an integer using a C function, sometimes it works, but sometimes the conversion is totally wrong. I proved this function in the compiler in my PC and I am pretty sure that it worked. What could be happening here? Martin P....
If you are really so very desparate for code and memory space, you will have to write your entire functions in assembler. This might be worth the effort if you are writing an ISR or perhaps you have to handle many 24-bit values in a very short time. But, before you do th...
There are many possible ways to do this - user code can be waiting for a lock that never gets released, either because it was leaked or there was a logical deadlock or livelock, or it could be in a clever infinite loop, etc. Once again, any unsent response will never happen...
