Solved

Hi Team！ I would like to consider a gimbal with STEVAL-GMBL02V1 dev-kit.I would like to change the firmware and verify it, but only a hex format firmware is available. Is it possible to obtain the C/C++ source code?  

I there a way (device or API) to control STM32 resources via JTAG or SWD without the need to downloading a custom program?  For example, setup GPIO pin with pull-up and direction and then write value.  In addition, be able to perform more advance scenarios like reading/writing data via the I2C, SPI, or UART ports.  This would mainly be used for testing out new boards or manufacturing environments.I've seen projects like Firmata do similar, but was curious if there was something else provided directly by ST (or community) as more of a long-term standard.  Would be nice if something like ST7Programmer tooling/API could offer this ability.Thanks in advance for any help/references.

Hello everyone, I want to enable the AAT(Automatic Antenna Tuning). Can someone provide a example Thanks 

I have examined the FSM example folder on github and, while there is an example for an external magnetometer, I haven't found any examples for an external barometer. Is there such an example? And if so, where can I find it?I believe I can create my own, but it is always easier to follow a previous working example. Thanks!

I have learned that STEVAL-SMARTAG1 can power MCU through EH of ST25 to achieve wireless transmission function, then can I replace the digital sensor with a thermocouple as a principle to collect data?

Board: STM32F429I-disco1How can I send an I2C command when a button is being pressed? So I set up a FlexButton to act as a toggle button and set its interaction to call a function (ToggleMute) which I would need to implement.My idea was just to use the HAL_I2C_Master_Transmit function in the ToggleMute function which is in the file Screen1View.cpp/hpp but the issue that I ran into is that the variable hi2c3 which I need to pass to the HAL_I2C function is privately declared in main.c meaning I cannot access it. So I do not know what to do.I thought of maybe having to use the Model and ModelListener files by making a function in main.c which is the functionality of the ToggleMute function so that way my ToggleMute function in Screen1View can just call that function in main. Even if that is correct I would not know how to go about it exactly. 

Hi, I assigned all used GPIOs to desired functions except the PC2 at ball M1. The datasheet seems doesn't indicate this pin would be something special. I just need SPI2_MISO there but MX doesn't allow select anything, all choices are off just the Reset_State. Is it a bug? I use latest version of MX 6.9.2.

Hi, What is acceptable ripple voltage on power supply pins on stm32? I am using DC/DC converter and have 100mVpkp at the output (+3.3V). I tied VDD and VDDA pin to one power supply as I am not planning to utilize an internal ADC. I am just planning to use this mcu to read analog signal from an external ADC and generate PWMs. Is 100mVpkp critical for this application? I have attached a snapshot of the schematic! Let me know if I need to clarify anything. Thank you 

Hi allI want to create a GUI, similar the Scroll Wheel in the provided examples.The only difference to the Example i need, is that it should always update the Selected value from the scroll wheel. Also when moving around. So I used the scrollWheel.getSelectedItem() which returns the selected item. But as the documentation says:"Gets selected item. If an animation is in progress, the item that is being scrolled to is returned, not the item that happens to be flying by at the time"What i actually want is to the the item which is selected also when flying over. Do you have a Idee, how i can get the selected Item also when a animation is in progress?

Currently using STM32L496.​Pressing the button long key enters STOP mode as shown below.HAL_PWR_EnterSTOPMode(PWR_LOWPOWERREGULATOR_ON, PWR_SLEEPENTRY_WFI);​Additionally, you can exit STOP mode by pressing the interrupt button.​For reference, after exiting normal mode, use SystemClock_Config(); You must enter to return the timer to its original state.​​When you press the interrupt button, it exits STOP mode and returns to NOMAL mode (TIMER, UART, I2C, SPI, LCD, etc. all operate normally.)​However, only the ADC does not work.​Is there any additional code that needs to be added after exiting the interrupt?

Hi! I am a student new in this theme and i am searching for components to create a energy harvesting NFC system. This will work only with the power given by a mobile reader though the antenna. Searching for a dynamic tag, i have see that only M24LR and ST25DV Series can use this feature, but i prefer ISO14443-A because it is a mandatory system requirement. Is it impossible to use the M24LR in a energy harvesting system? Is there any other solution using the ISO14443-A protocol?

I made a custom STM32 board based on the schematics of Nucleo-G071RB and X-Nucleo-GFX01M2. On the development board, the TFT LCD works. However, when I program my custom board using STLINK-V3SET, the TFT LCD only shows a white screen.I did changing TFT LCD(DT022CTFT) : new TFT LCD just same.  this is my custom board's MCU.   This is my custom board's SWD pins 1. How can I program using STLINK-V3SET in TouchGFXDesigner?

Hello,  I don‘t understand the Syntax of the Function  rfalWriteMultipleRegister(). After trying and don‘t receive any Data. Can someone provide an example on how to use the function.  Thank you very much Rgds 

Hello I want to measure the distance of water in a cylindrical container to the lid of the cylindrical container. I need to find the height of the water by subtracting the measured distance from the height of the cylindrical container. Since there is no pure water in the pipe, we cannot use an ultrasonic sensor. However, the chemicals in the water are not flammable or explosive. What I want to ask is, is there a distance sensor you can recommend to measure water distance? pipe height 400 cm.pipe diameter 100 cm.

Hello all,I developed a board based on the STM32U585RIT6 (without SMPS package) based on the STM32U5 guidelines.I've encountered a problem during tests: When I turn on the MCU block on my board, the MCU draws >600mA of current.My first reaction was to test continuity between GND and 3.3V. Result: no continuity and insulation around 49kOhms. It was very strange. I also tested the possibility of a short between the MCU pins, but nothing.However, I still manage to connect to the MCU with a STLINK. I also used a thermal camera which shows me that the problem is with the MCU.I continued by gradually removing the components around the MCU to exclude a potential external short circuit.=> I tested the MCU in 2 main configs:1) All GPIOs are not connected to anything, but I kept all decoupling capacitorsResults--> Abnormal current  >600 mA consumed by the MCU. 2) I removed everything off the board around the MCU (GPIOs connected to anything)I directly feed the MCU powe

Sometimes, I am reading zeroes from IIS3DWB FIFO. I thought maybe it is because I am using a protoboard (using MKI208) so I connected it directly (with cables) to RPi 4 but it still happens.I guess it is not normal to find these in FIFO, can it be due to SPI communication/electrical issues ?

Hi,I developed my first board with a STM32L431RCT6 (80Mhz) but sometimes I have problems with an external 8MHz crystal (HSE switches to HSI). I configurated the peripherals and the clock with STM32CubeMx.This is a clock configurator page (I enabled CSS):This is a RCC page:The 8Mhz crystal is connected on the pins PH0 and PH1 with two capacitors of 20pF.When I stop the firmware after the System Clock configuration the HSEON and HSERDY registers are set to a corrent value (set to one).Then a few lines of the code after (at the beginning of the while loop) the board switches to HSI clock.Many times the board fail to startup (HSE switches to HSI) but sometime it work fine (HSE without switching to HSI).The CSS interrupt is never trigger..  I don't understand the error. Can someone help me?  I attached the source code and the ioc file.Thanks,Edo 

I am using NUCLEO-H753ZI (STM32H753ZITxLQFP144).Using ADC1_IN3 Single-ended (PA6) and DMA (Mode:Circular),I want to perform high-speed sampling. (1MSa/s or more)Calculated: 3.125MSa/s = 50MHz / 4 * (1.5 + 6.5) (Supplement: clockPrescaler=4, 1.5Cycles, 6.5ADC clock cycles)*The clock uses 50MHz of PLL2.However, it seems that the speed is only around 500kSa/s.Please advise if there are any possible causes or places where the settings may be incorrect.

I am using STM32F407 with eclipse IDE. And I want to generate PWM signal using TIMER12. After all the configuration, when I call, "sMasterConfig.MasterOutputTrigger = TIM_TRGO_RESET; sMasterConfig.MasterSlaveMode = TIM_MASTERSLAVEMODE_DISABLE; if (HAL_TIMEx_MasterConfigSynchronization(&htim12, &sMasterConfig) != HAL_OK) { Error_Handler(); }"  inside MX_TIM12_Init(); function, the MCU just stuck and I get no print function. On debugger console I get a the following message,"Wrong parameters value: file ../../stm32f4-hal/stm32f4xx_hal_tim_ex.c on line 1636".And this line refers to the following lines of codes,  " HAL_StatusTypeDef HAL_TIMEx_MasterConfigSynchronization(TIM_HandleTypeDef *htim, TIM_MasterConfigTypeDef *sMasterConfig) { uint32_t tmpcr2; uint32_t tmpsmcr; /* Check the parameters */ assert_param(IS_TIM_MASTER_INSTANCE(htim->Instance)); assert_param(IS_TIM_TRGO_SOURCE(sMasterConfig->MasterOutputTrigger)); assert_param(IS_T

Flash on the STM32WB1M is supposed to be 320K long, as advertised as well as in the ref manual RM0473 and in the Memory Manager in CubeMx. But the default linker script out of CubeMx only gives 110K flash section length. If I try to put an emulated EEPROM section at the last couple of pages (yes, incl. modifying the linker script), say 0x0804E000, I get a hard fault when trying to read that address. Same if I try to read that address from STM32CubeProgrammer. It turns out I can only read (from STM32CubeProg or emulated EEPROM usage) to approximately the 110K past 0x08000000. I could read a page or two starting at 0x08020000 and beyond that I got errrors. Am I missing something here? It's as if addresses beyond about 110-112K in flash are invalid...

Hi,In ST25RFAL library, version 2.8.0, in rfal_isoDep.c, function rfalIsoDepHandleControlMsg(), when ISODEP_S_WTX messages is handled, the code limits how many times a card can request wait time extension, specifically, this line:  if( (gIsoDep.cntSWtxRetrys++ > gIsoDep.maxRetriesSWTX) && (gIsoDep.maxRetriesSWTX != RFAL_ISODEP_MAX_WTX_RETRYS_ULTD) )   By default it limits to 20 (RFAL_ISODEP_MAX_WTX_RETRYS) wait time extension requests.What is the reason for having such a limit?Thank you,D.

Hello,I am trying to create an application that is able to use the ST25R3911B-DISCO to read ISO15693 tags. I read on the forums and understand that the reader does not natively support ISO15693 tags but that there is a RFAL library created by ST which implements all the low level details of ISO15693 protocol so that I don't need to. I was looking on how to implement this on the board and noticed that the firmware already has some of the RFAL library in its files (at least the ones I need). So I was wondering, are some of the RFAL libraries implemented in the firmware already or do I still need to do anything to the firmware to implement them. As well, I was wondering if there is any documentation for the command sets of the RFAL library or more or less how to use the library itself.
