Resolved! STM32 Debugging Tools and Real-time MCU Inspection?
Hello,Previously when working with NXP MCUs, I was able to inspect MCU registers and memory whilst debugging through a convenient interface built into the IDE.I'm wondering if the STM32Cube ecosystem, or other ST tools, can provide equivalent functio...
Can the STM32 Power Shield (LPM01A) be triggered on AND off?
The X-NUCLEO-LPM01A Power Shield can be triggered by the target device to start acquisition, using the D7 pin. Can it also be triggered to stop acquisition?Also, my power shield is currently running v1.0.1. The latest version of the firmware is 1.0.6...
Using SWO with built-in stlink on nucleo H743ZI2 board
I'm having trouble getting SWO to work using openocd on the NUCLEO-H743ZI2 board. I've removed SB26 as per the user manual for this board. This should leave the SWO pin (PB3) connected to the stlink SWO, meaning I can get ITM output over the usb conn...
STM32H7xx - PLL input frequency range settings
Hello,this is a description of PLL settings from a reference manal00: The PLL1 input (ref1_ck) clock range frequency is between 1 and 2 MHz (default after reset)01: The PLL1 input (ref1_ck) clock range frequency is between 2 and 4 MHz10: The PLL1 inp...
Help setting up a comparator and counter to count frequency of 0-3.3V square wave input
HelloI am using a STM32L476VG. I want to use pin PC4 (named 'comp_negative') and PC5 (named 'comp_positve) for comparator inputs. Reading through 'stm32l4xx_hal_comp.c' it gives some idea how to set this up. I have also seen someone else has had a si...
Resolved! STM32F7: setting PA15 as GPIO breaks SWD connection
I'm using an STM32F750 with the JTAG/SWD pins as follows:PA13 (JTMS/SWDIO) is connected to my debug headerPA14 (JTCK/SWCLK) is connected to my debug headerPA15 (JTDI) is to be used as a general-purpose outputPB3 (JTDO/TRACESWO) is connected to my deb...
Enable XIP and write/erase external flash concurrently
Hi ST,I'm using STM32H723 with mx25lm51245g to test XIP feature, we want to run the program in the external flash, in the meantime we want to write/erase external flash.We found that once the XIP feture is enabled (memory mapped mode), if we try t...
Is it possible to monitoring local or static variables using SWV ?
How to monitor Static of local variables using SWV?
STM32F PWM Signal Configuration During Working
Hello, currently I'm working on a PWM signal generation project. I can generate PWM for certain values. But I need to change them during experiment.For example, at start PWM going to work on 1KHz freq. and 10ns pulse witdh. Then I'll change them with...
