Hello,I would like to select STM32F0 examples projects from the New Project -> Example Selector.I have CubeIDE, and in the MCU/MPU selector I can select my NUCLEO-F072RB. In the Example Selector I can see examples for STM32 F4, F7, G0, G4, H7, L5 and WB only. I have no examples for the F0 MCUs.In the STM32Cube Repository Folder I have both the STM32Cube_FW-F4 and the STM32Cube_FW_F0 folders with all the examples.I've checked for updates, I have the latest F0 firmware package. My Firmware Installation Repository is set to \STM32Cube\Repository... ...can anyone help me understand what I'm missing to get the examples in the example selector?? I feel like this is going to be a facepalm....Thanks!

Using TouchGfx 4.14.0, select "Understanding Application Structure" example and run on target (stm32f469i-disco).It will stack overflow on the 3rd transition:The cure is to increase stack size from 2048 to 3072 (\TouchGFXProjects\MyApplication_1\Core\Src\main.c, line 69).Please fix!

Hi,I am using the LSM6DS3 with I2C at 400 kHZ. I would like to know the pin capacitance value so as to calculate the value of the required pull up resistors. I was unable to find this in the data sheet.Thanks

For now, all the information I got about this library is it only supports to F​4. So, will it work with F7 ? ​Thanks​.

Hello.How can i use active miller clamp function of STGAP1AS mosfet driver for paralleled mosfets?

Hi,I'm trying to debug STEVAL$STSPIN3202 motor control board. I have generated code by using motor control workbench. I compile the code without anyproblem, but i recieve attached error message.I'll be glad to get your support.thanksMustafa

I'm looking at the IHM03A1 stepper driver board, which claims to handle 10A per phase. However, it's documentation says it only has .1 Ohm 2 W current sense resistors. Wouldn't that only be able to handle ~4.5 Amps of current?https://www.st.com/content/st_com/en/products/ecosystems/stm32-open-development-environment/stm32-nucleo-expansion-boards/stm32-ode-move-actuate-hw/x-nucleo-ihm03a1.htmlhttps://www.st.com/resource/en/user_manual/dm00206777-getting-started-with-the-high-power-stepper-motor-driver-expansion-board-based-on-powerstep01-for-stm32-nucleo-stmicroelectronics.pdf

Hi,we are having difficulties in order to find solution for STM32H7 Nucleo Board (NUCLEO-H743ZI2). When we are trying only toggle a pin ( interrupts are closed --> 480MHz)freq is not passing 20MHz. When i check ref documents GPIO section, it says “Fast toggle capable of changing every two clock cycles�? . (Page 527) But we can't achieve to these speed. Can you please let me know if there is something i need to do? here are some links i have found from the community.https://community.st.com/s/question/0D50X00009XkWd2SAF/why-i-get-stm32h7-gpio-toggle-speed-just-only-at-167mhz#:~:text=Why%20I%20get%20STM32H7%20GPIO%20Toggle%20speed%20just%20only%20at%2016.7MHz%3Fhttps://community.st.com/s/question/0D50X00009XkWN7/stm32h7-gpio-togle-max-frequencyhttps://community.st.com/s/question/0D50X00009cdgGjSAI/stm32h7xx-fast-gpio-toggleBy the way, when we face this problem we thought that we should use SPI port. But in this case we get following SPI CLK signal erosion(attached pictures). Can you p

Updating to CubeIDE 1.14.1 I have seen that I can choose some new STM32H7xx MCU's ( especialy the STM32H725, STM32H735 and STM32H730 ). They are very interresting for me ( 3. CAN interface and 2x OCTOSPI with hyperflash support ). Is there any roadmap when this devices will be avaiable?Martin

I am getting so much noise on analog pin without connecting any analog signal. I also tried by changing analog pin but still i am getting so much of noise in analog pin. I am calculating analog value for 50 Hz signal. Is there any way to calibrate STM32F413 micro controllers ?Is there any mathematical calculation available for calibration of 50 Hz signal or to reduce noise from signal ?Please help regarding above topic.Thanks in advance.

When it comes to the imageProgress widget, can someone tell me if the entire rectangle is re-rendered (invalidated) when the function setValue() is called? Or only the parts that are changing rendered?It appears to me that it is. Animation performance would be better if only the parts changing are rendered.Note that I do have "Anchor progress image at zero" selected.I did search through the TouchGFX documentation, but did not find an answer to this question.

Hi!I have NUCLEO H743-ZI board, and I am trying to create PWM sequence with advanced timer 1, by utilizing DMA feature.Code is mostly generated by cubeMX.I am using PWM mode 2, Center-aligned mode 1.Code works, untill DMA loads into compare register (TIMx_CCR1 register) value 0, than it hangs.After some digging through HAL code, and manual, I presume this happens because timer stops generating interrupts, which force DMA to load new values into compare register (TIMx_CCR1).My theory is that interrupts are generated when counter gets bigger than compare value, which never happens (lowest counter value is zero, and zero is not higher than zero, thus no interrupt).Now how to resolve this issue…..TIMx DMA/interrupt enable register (TIMx_DIER) has flag „Bit 8 UDE: Update DMA request enable“, but enebling it did not help. Simultaneously I set flag „Bit 0 UIE: Update interrupt enable“, but to no avail, I am still stuck…..Did anyone came across this problem, and how was it resolved?At this mom

Hello,I'm currently working on an PCB for an lecture about uC programming. It should be an education board for students to engage and learn hardware programming using an STM32 and the given ICs and interfaces on the board.Because this pcbs will be often reprogrammed but will have some fixed parts I thought on using an on-board debugger to make it more comfortable to use and minimize possible sources of misuse. It would be handy for the students to flash the STM32 through an usb cable.I've searched around and found out about an open source project BMP (not sure if it is exactly what im looking for) and and the on-board solution from segger (J-Link OB).However I wanted to know if there are any other possible solutions for programming/debugging STM32s on custom pcbs I've missed. Is there an appropriate way to realize this or would you tend to use an small external debugger (STLINK-V3MINI, J-Link EDU mini)?Thanks for any suggestions and sorry if I might have missed any already existing thr

Hi,I would just like to know the date code on the LSM303AGR on our PCB Board. So far I have not found any document to interpret the date code. The markings are 636 AGR.Regards,Markel

Hello,I am working with the ISO15693 chip ST25DV64K for the first time.The V_EH output goes to a 1.8 V regulator and the output of the regulator supplies a microcontroller.I would like to know how can I ensure that the microcontroller first writes its data into the EEPROM of the ST25DV64K, via I2C, and then the ST25DV64K chip is ready to be read out via RFID.If the voltage at the V_EH is too low and the microcontroller is not yet on, I do not want the ST25DV64 chip to be accessible via RFID. Only when the microcontroller is on and the data in the EEPROM (ST25DV64K) has been updated can the ST25DV64K be read out via RFID.How can I achieve this ?

Hi all,I have trouble with receiving one byte on SPI1-DMA1. All is working if I set more bytes to transmit/receive (2 and more) but when I try to send only one byte it do not trigger interrupt on Rx channel (DMA1 channel 2).I can see transmitted bytes on logic analyser. Transmitting is without problem and one byte is correct too and triggering Tx interrupt (on DMA1 Cchannel 3).Interesting is that when I set receive one byte (spi1.rxLength = 1) and transmit two (spi1.txLength = 2) so Rx interrupt rise after one byte received.I do not found any detail description about trigger DMA channel from SPI and counting received bytes. Could you help me with to found where problem is?Here is preparig struct://------------------------------       spi1.rxLength = 1; //for DMA_SetCurrDataCounter       spi1.txLength = 1; //for DMA_SetCurrDataCounter       for (int i = 0; i < 10; i++) //some test

Hello ,According to the st25r95 datasheet:"After the power supply is established at power-on, the ST25R95 waits for a low pulse on the pin IRQ_IN (t1) before automatically selecting the external interface (SPI) and entering Ready state after a delay".I have a custom board and I want to read the device id over spi, but the IRQ_IN pin is not connected. Can it work without IRQ_IN low pulse? Can I communicate with the device, currently I have nothing on MISO line.

We have already a product based on STM32F429VGT6 which uses USB Host feature to read out data from plugged in USB-memory sticks. Our device have an USB A input so that normal USB-sticks can be inserted.This works well.Now there is an USB-stick which is going to transfer data via a FTDI FT230XS chip. The STM32F429VGT6 needs to communicatie with this chip. Should that be possible?Is there already software which does that?Best regards,Hilco

HIcommunityI am new to the STM32 world and am looking for the name of the library file in which the function HAL_SPI_Receive (..) is included as source code or the direct source code of this function.thanks for help
