Debug with Logic Analyzer to show GPIOB bit signal

hi, I am trying to use the logic analyzer to capture the output pin on my MCBSTM32 board. I have try to add "GPIOB" into Current Logic Analyzer Signals under Setup Logic Analyzer Menu, but couldn't seems to do that successfully. May i know whats the right way to add and monitor the signal? This pin is connected to an IR Emitter and the 38Khz carrier frequency toggle by a Timer ISR.

regards
Thanks for any input.

  • Thank you for all the input. The GPIOB signal is found in ST Micro STM32F10xx Reference Manual. What i am trying to do is read the levels from an input port connected to an IR Receiver, save and retransmit it in 38Khz modulated frequency through GPIOB.0 pin. The 38Khz carrier is generated by toggling the GPIOB.0 pin with period set to 1/38Khz. I have try to store the value read from the output pin into a variable and in stimulated mode it works but not in debugging mode using the ULink Cortex Debugger. Where the value doesn't toggle. Is there a debugging tool in keil to measure the period generated from the output in simulation?
