Tutorial 6: Logic analyzer in Keil

[@asntrk1]

I discovered how to use logic analyzer a few days ago after many tries and searches. Thanks for sharing. Especially pointer approach would be very useful.

How did u make the graph stable (freeze) in logic analyser( from 6:30 to 6:40)

[@embeddedsystemswitharmcort9051]

If you download the code and run it on the board, the graph is automatically plotted in the logic analyzer. I don't understand what you mean by "stable". Is your output unstable?

sir for stm32f401re , the normal code HAL_GPIO_WritePin(GPIOA,GPIO_PIN_5,1);
HAL_Delay(500);
HAL_GPIO_WritePin(GPIOA,GPIO_PIN_5,0);
HAL_Delay(500);
pin pb3 = swo, pa14 = tck and pa13 = tms , what variable name should i give in the current logic analyser window

Thanks for tutorials, I will save and watch them later

Hope you enjoy!

This feature I can you with USB ST-Link or must use SWD connecter with ST-Link. Thanks!

[@embeddedsystemswitharmcort9051]

USB ST-LInk uses Serial Wire (SW) protocol. I think both should work.

How do you set a global variable to f.e. GPIODATA for reading a PWM Signal? The IDE tells me it is not a compile-time constant.

[@embeddedsystemswitharmcort9051]

You can directly use any global variable, such as GPIOA->ODR, making sure to setting the mask and shift to make your data easier to view.

Thanks for tutorial. I connect the swo. But I get the "Trace: sw buffer overrun" error.

[@embeddedsystemswitharmcort9051]

Yes, if I monitor two or more variables, I got the same error. One variable would be fine. I guess the communication between the board and PC is not fast enough.
