Hello,I am searching for the input/output impedances for my STM32L476RG microcontroller and I can't find any information in the microcontroller datasheet or else where on the web. Are those values given in any documentation? If not, can they be calculated?Regards,

Hey guys and gals! I am facing a persistent problems when configuring system clock on the STM32L152 to 32MHz using SPL. It smoothly runs at 24MHz but always freezes when making it to run at its maximum freq.The MCU's max clock frequnecy is 32MHz and it runs just fine when configuring the clock using STM32CUBE IDE and HAL. The intention is to run it from HSI (16MHz) via the PLL in this way: It refuses to work in my SPL-based code, although the procedure seems to be the exact analogy to the HAL code:void init32MHzClock() { RCC_DeInit(); FLASH_SetLatency(FLASH_Latency_1); PWR_VoltageScalingConfig(PWR_VoltageScaling_Range1);   RCC_HCLKConfig(RCC_SYSCLK_Div1); // HCLK = SYSCLK RCC_PCLK2Config(RCC_HCLK_Div1); // PCLK2 = HCLK RCC_PCLK1Config(RCC_HCLK_Div1); // PCLK1 = HCLK   RCC_AdjustHSICalibrationValue(0x10U); // default HSI calibration trimming value RCC_HSICmd(ENABLE); while (RCC_GetFlagStatus(RCC_FLAG_HSIRDY) != SET);   // PLL clock from 16 MHz HSI: RCC

Thank you for helping.Environment: TouchGFX Ver 4.15.0What are the intflash.hex and target.hex files built and created by TouchGFX used for?Thank you.

I need generate 15 phase signal in ATOM GTM. How I phase shift between ATOM channel's?

Hello,I wrote some codes and it worked succesfully. Then I wanted to add some global variable for computing a value but global variables which are added later, their values did not change, altough I set the refresh period setting ( while are changing global variables which are declareted before) . And their initialize values also don't change (there is a "?" symbol everytime). Additional their adresess is seen 0x000000. What could be the reason of this? How can I add a global variable for wathing what is going on?Regards,

I had to enhance the stack size using __process_stack_size__ value to make my software running and I would like to know how to measure the stack remaining size. I tried commenting out the ram init in boot.s and fill the stack ram area with a 0x55AA pattern using the debugger, but the area is still initialized. Is there an easy way to know the stack occupied size??

Hi,In code generated by SPC5Studio for SPC582B microcontroller there are some macrodifinitions, which validate setting of the clock.Particularily the one (components\spc582bxx_clock_component_rla\lib\include\clock.h):/* Check ratio between SPC5_LIN_CLK and PBRIDGE_CLK.*/ #if (SPC5_LIN_CLK != 0U) && (SPC5_PBRIDGE_CLK < ((1UL * SPC5_LIN_CLK) / 3UL) || SPC5_PBRIDGE_CLK > ((2UL * SPC5_LIN_CLK) / 3UL)) #error "SPC5_LIN_CLK outside acceptable range (1/3 PBRIDGE_CLK...2/3 PBRIDGE_CLK)" #endifDue to the #if equation - LIN_CLK must be 2 times bigger than PBRIDGE_CLK.But due to #error comment - LIN_CLK acceptable value is half of PBRIDGE_CLK (between 1/3 and 2/3 of PBRIDGE_CLK actually).Which one is correct?Best,Yannek

HiI have discovery M24LR and CR95HF demonstration board, I read and write data by ST application software successfully but when I use DLL file and LABVIEW software according to AN3954 I read just strange data, for example when I read data from tag I read:800D00FF214A886CE15902E05C5700according to page 42 of AN3954 the main format is correct but I can't understand the read data, my goal is to read the whole data of EEPROM

Hi, I am trying to do some audio project based on STM32F7/F4 series. I have got STM32F769I-DISCO board. I have downloaded x-cube-audio v.1.1.1 and x-cube-usb-audio v.1.0.0.I have unpacked both packages and I am trying to build and run some example (starting from Import->Existing project into workspace). Every project that I am trying to build ends up with "Nothing to build for project..." in CubeIDE. What is the best way to start with such examples?

The recommended voltage range is 85 volts which is also the same as the recommended voltage for the POWERSTEP01 device.Why max Voltage 50V on IHM03A1 development board?

Hi,I'm seeing some odd behavior with the icon decorators on excluded source files:Create a new STM32 project with everything as defaultBuild the project ... all goodAdd a source file, say demo1.c that contains a single functionAdd another source file, say, demo2.c, that contains a single functionCreate two new build configurations, say, Demo1 and Demo2Set Demo1 as the active configuration and exclude resource demo2.cSet Demo2 as the active configuration and exclude demo1.cBuild the Demo1 configuration ... look in the console output to prove it built demo1.c and excluded demo2.cBuild the Demo2 configuration ... look in the console output to prove it built demo2.c and excluded demo1.c...but the icon decorators are not showing the excluded resourcesThis is with STM32CubeIDE v1.4.2Any ideas?Thanks

The release notes no not mention MacOS 11, but has anyone tried?I want to upgrade my Mac, but not if STM32CubeIDE stop working!

Hi, When i use STM32CubeMonitor, I can't understand add some of values.*.out file is not created when stm32 project debug?​How to get this file or know value's start address?

I want to know the difference of device tree compiling the with the Developer Package and Distribution Package.​I understand that when I create my own machine, I can create device tree by following 2 method. Method 1) Building device trees with Developer Package (separately from bitbake) This method is described in following Wiki page. https://wiki.st.com/stm32mpu/wiki/How_to_compile_the_device_tree_with_the_Developer_Package Method 2) Building device trees with Distribution Package (included in bitbake) This method is described in following Wiki page. https://wiki.st.com/stm32mpu/wiki/How_to_create_your_own_machineWhen I checked the operation with the device tree created by above two methods, the behavior was different even though the device tree source before compiling was the same.Specifically​, with device trees build with Developer Package I can use remoteproc to exchange data with Cortex-M4, but with device trees build with Distribution Package I can

Can I download still somewhere the old legacy versions of Atollic Truestudio (e.g. 9.x)? I would really need an old version for legacy compilation...

Hi,I tried to I2C Loopback test on STM32F401.I added two I2C Ports and checked NVIC Setting.Following some of tutorials, below function is craete automatically.but when i generated codes, this function was not crated.this function is wrote by user?

How to port UCOSIII to SPC5x in SPC5 Studio?Anyone succeeded? Or is there any offical tutorial?

We have confuse for shelf life for SPC560P40L3BEAAY If the DC over 2 years ，is it still Effective? Or have some risk? Do you have document for date code police or storage shelf life can send us? Thank you in advance. Looking forward to your reply soon.

How does THE SPC560 MCU achieve software reset, I can't find a register that the software can reset.

In my CubeIDE 1.5.1 project I have proprietary custom defined symbols that deleted every time I generate the code from IOC.How can I protect them from being removed?

Hi everyone we are trying to debug the program in SPC560p dicovery board when we are using the UDE debugger in that we getting some errror which i mentioned below please help us in this regard ,we need configure anything in the UDE debeggerMessage from component 'PpcJtagTargIntf' :Can't connect target !Message from component 'PpcJtagTargIntf' :Failed to open communication channel !Message from component 'FtdiCommDev' :Failed to open FTDI device driver !Message from component 'UDEDebugServer' :Unable to establish connection . To correct the situation, check configuration file entries and try again. Kidlt help us in this regardThanks in AdvanceSaravanan Mariyappan
