Hello there. I have a homework to do stopwatch, but I'm having a few problems. 
In code there are 4 button interrupt(B0-B3), 1 timer1 interrupt for 1 ms and USART2 interrupt. 
Buttons and timer interrupts work properly but USART2 interrupt work just…

Hello,

I am trying to find out GPIO mapping on a board with an STM32F407 (which firmware function is related to which GPIO). I know I could do it using a LA, but pins are note very accesible.

I have no access to source code so... I only have a firmware…

I am facing issues with initialization of an object array within the Constructor. I would like to initialize my array using initialization from brace-enclosed lists. But the armcc compiler for some reason, doesn't compile my code nor throw me a warning…

Hello alltogether,

for me a binary-file (.hex or .bin) looks like there is no structure in it. 

Do you know if it could be possible, to mark all my binarys, so that i can recognize? E. g. with a unique string i could grep or ? Or let's say line xyz start…

I'm new to uVision for a University project and since trying to get my code to build on my PC at home I get this error with any code I try to compile. Anyone know any way to fix this? I've been racking my brain for hours trying to find a solution as I…

Hi,

I am trying to compile my code but I am ending up with ERROR: L6218E : Undefined symbol Bit (referred from main.o).

Where Bit is a struct that I am using to store boolean values. For eg:

In variable.h file

struct
{
	unsigned bPowerONStatus : 1;
…

The scenario is STM32L0 (ST Nucleo evaluation board) and custom firmware.

When I execute the code in debug mode and it stops at main function, the value of FLASH->SR is 0x0000000C, and it looks good for me.
Now, without running the code, if I simply…
