I am using STM32CubeMX ver 5.1.0 for stm32L433, In my old projects, i use STM32Cube_FW_L4_V1.10.0 with CubeMX ver 4.Now i'm facing with two problems,First, is it possible to use STM32Cube_FW_L4_V1.10.0 with CubeMX ver 5 (I don't know how to change firmware package in CubeMx). Because it is difficult to change every previous projects i had made.Seconds, I cannot find STM32Cube_FW_L4_V1.13.0. Can you help me with that.

Hello Everybody, I've a big problem to debug my EVAL-ST95HF board, i tried two ways to fix that:the first one: i unzipped the source folder getting EVAL-ST95HF_FW_V3.7.0 that i used with keil uvision5, when i build i get this error message and i've seen this file doesn't exist within the indicated directory and tried to install a previous version e.g keil uvision4.74 i've no managed to open project with the last one Rebuild started: Project: DEMO_BOARD_ST95HF*** Using Compiler 'V5.06 update 6 (build 750)', folder: 'C:\Keil_v5\ARM\ARMCC\Bin'Rebuild target 'DEMO_BOARD_ST95HF'compiling Firmware_Saving.c...compiling menu_writer.c...compiling menu_Tagemul.c...compiling menu_cardemul.c...compiling menu_reader.c...compiling main.c...compiling common.c...compiling hw_config.c...compiling menu_auto.c...compiling menu.c...compiling stm32f10x_it.c...compiling PongExample.c...compiling proprietary_p2p.c...compiling drv_spi.c...compiling drv_95HF.c...compiling drv_interrupt.c...compiling drv_uart.c

I'm using an STM32F466RE to drive a motor via PWM and want to sample a current monitor via ADC during the active part of the pulse so that I can integrate the amount of power delivered to the motor. This will require the sample rate to be high enough to obtain samples during the minimum pulse witdth (1/100 of PWM period) and what I'd like is to prevent the ADC from capturing wasted samples during the off part of the pulse since that would just be a heap of zeroes that need to be integrated.Is there any way to configure the device so that continuous ADC sampling is gated by the state of the PWM output? Or will I have to sample continuously and figure out what to ignore?At the moment I'm planning on driving the PWM at ~500Hz, sampling at ~50kHz, and using the calculated power in a control loop updated at maybe ~50Hz.

I don't use libraries.I got I2S working by polling. Below was my test. I had an array of 16 bit signed words for a tone of 1khz. The I2S pins from the MCU feed a an external DAC and produces a very nice tone.  RCC->APB1ENR |= RCC_APB1ENR_SPI3EN; // turn SPI3 clock on   Config_STM_Pin(GPIOB, 3, 6, H_GPIO_Alt_Function, H_GPIO_Output_PushPull, SlewRate_Medium, No_Pull_Up_or_Down); // I2S_Bclk B3 Config_STM_Pin(GPIOA, 15, 6, H_GPIO_Alt_Function, H_GPIO_Output_PushPull, SlewRate_Medium, No_Pull_Up_or_Down); // I2S_LRClk A15 Config_STM_Pin(GPIOD, 6, 5, H_GPIO_Alt_Function, H_GPIO_Output_PushPull, SlewRate_Medium, No_Pull_Up_or_Down); // I2S_Data D6   AudioMutePIN(1); // mute off   // set up I2SPLL   RCC->PLLI2SCFGR = (271 << RCC_PLLI2SCFGR_PLLI2SN_Pos) | (2 << RCC_PLLI2SCFGR_PLLI2SR_Pos); // this gives correct I2S_clock   // enable I2S clock   RCC->CR |= RCC_CR_PLLI2SON;   // wait until stable   while((RCC->CR &am

Hi everyone!I'm new to embedded and that's my first board - STM32F103C8T6. I'm trying to program it using ST-LINK V2, but getting error "can not connect to target" all the time. I've tried to done that on two different PC with Windows 7, but result remain the same.I've changed modes and reset board several times, as it said in error messages, but it didn't helped either. Board - STM32F103C8T6Utility is STM32 ST-LINK Utility v4.4.0Driver is STSW-LINK009There are some screenshots and photo of hardware attached Waiting for your advice a lot ;)

Hi,2 questions related to HW device, which works with STM32CubeProg:1. Can STM32CubeProg work with ST-Link v2?2. Can STM32CubeProg work with a J-Link device (rather than ST-Link)?Thanks,Aviv

Hello,Hardware : STM32F769-DISCOCompiler: Atollic 9.3.0I am trying to merge the Fatfs with mbedtls example from cube 1.15mbedtls has tx and rx buffers at SRAM2 region.Fatfs sample program fails to write and read a file.Can anyone look at the linker script and MPU_Config() function in main.c if I am doing it correctly.I am attaching the project folder.PS: simple fatfs program without any linker file modification works OK.Thanks,Tushar

I am searching for an MCU with dual Ethernet. Do any of the ST cores have dual ethernet? Thanks in advance.

programmed in IAR, for debugging im using stm32-utility,in this when i try to connect the target it shows can not connect to the target.What i did in this is 1.connected the jtag pins with respective.2.power supply 3.3v3.NRST is high4.BOOT0 is high

I am attempting to integrate a bootloader and an application into my stm32f7 mcu. I understand this has been done numerous times previously, so apologies for probably small questions leading to larger ones.I am running into issues on the jump function between my bootloader (located at 0x08000000) to the application firmware (located at 0x0800FA00). The bootloader occupies two sectors of memory, and the firmware the remaining 8, in single bank memory mode. When i attempt to jump between the bootloader and the application, I would assume I would jump to memory address 0x0800FA00 + 4, which is the offset from the top of the application, but that does not seem to be successful. Prior to this jump, I map the interrupt vector to 0x0800FA00. (code snippet below)//Jump function void Bootloader_JumpToApplication(void) { pFunction appEntry; uint32_t appStack;   appStack = (uint32_t) *((__IO uint32_t *) APPLICATION_ADDRESS); appEntry = (pFunction) *(__IO uint32_t *) (APPLICATION_ADDRESS

Hi,I have small bitmap in a window, which normally I would like it appear to be transparent (invisible) but when a flag is set to become fully opaque, when the flag is cleared go back to being fully transparent.Kind RegardsMikeZ

Hi,I don't get why I can't set the border thickness/color directly when creating the BoxWithBorder object._boxWithBorder3(50, 50, touchgfx::Color::getColorFrom24BitRGB(150, 150, 250), touchgfx::Color::getColorFrom24BitRGB(0, 0, 0), 5,50)Indeed, it doesn't work and draw a box without a border! All the other params work, hence I can change its size, background color, transparency, but impossible to get it to be drawn with a border! Calling the setBorderSize function after the object has been created works just fine. An idea?Thanks.

We are trying to use STM32CubeProgrammer on Windows computers running JDK 11 and higher. Is this not supported by CubeProgrammer? It does not appear that the program contains the typical BIN file that we would edit to use a different version of Java installed on the machine. Is there any other option than having to use JDK8 as the main Java install?

@Eleon BORLINI​ Greetings of the Day Currently I am using LSM6DSM as my IMU. Now in this sensor I need to write my own function to obtain the quaternions and then based on that obtain the roll, pitch and yaw of the system. The question that I have is , does ST provide an IMU that already has on board motion processing that can calculate and return the quaternions ? Thank you

I'm trying to register a P-L496G-CELL01 Discovery Kit in the Concierge portal at www.stm32-c2c.com. The problem is that the portal doesn't seem to recognise that I click the confirmation email. Each time I try to register the new board, it just asks me to resend/confirm my email address. This is the first time I use the portal and have created a new account. I have tried several times, cleared cookies and restarted my PC.  Is there a solution to this?

I have bootloader initial position 0x08000000 and IAP 0x08004000 now.​First, I form bootloader jump to IAP code and it works fine.But my jump back to bootloader will stop.​Maybe I have a lot of IAP function enable.So I want to ask, besides __disable_irq() close NVIC, and any other way to deinit other functions?​Because I use __disable_irq(),but it seem isn't effect.when i back to bootloader code of GPIO inti funaction , it already haven't stop.

I just received version 2 of a board I designed. It has two STM32F427 on it. One a 144 pin used for main processing and the second a 100 pin used to control IO.The 100 pin MCU uses Ports B, D, E (all as outputs) to control outputs.Version 2 of the board is all hand assembled and soldered by an assembly house in China. I've had firmware running on Version 1 for weeks so I know the software is not causing the hard fault.The board is drawing about 200 ma more than it should which would indicate an issue somewhere.I debug the operation of the 100 pin MCU (output ports) to jump to the hard fault vector when any of the pins associated with ports B, D, E are set to being an output.I've looked hard at the board and parts under a microscope and do not see any solder bridges.I do see a lot (about .25v) of noise/hi freq oscillation on both VCAP pins. The voltage is clean on the VCAP pins of the 144 pin CPU.What would noise or oscillation on either of the VCAP pins suggest as being an issue?Both c

We have an existing embedded application with older GUI which is being ported to TGFX. For keeping the old logic, we want to display a blocking message box and wait for user response (button click) in a widget callback(GUI button callback). The problem is that the tick is ignored during executing the callback and screen stop rendering. Is there anyway to keep the screen alive during executing widget callback? Thanks in advance.

Dear all,how can the Cortex-M4 MCU (bare metal or RTOS) exchange data fast with the A7-Linux system? Can the M4 access the DDR RAM of the Linux system, like the PRU on the Beaglebone can do? In the datasheet, there is a connection between the AHB bus and the AXI bus, maked as asynchronous, so it looks like there is a DMA channel for this.I could not find an example code or project, showing a fast data exchange between the memories of M4 and A7. Does ST provide an example for this? Thanks,Michael

So why this issue in the STM32L1 discovery board.I also uploaded images regarding the problem in the board. 

Hi,I want to measure a static object and approximate tilt angle with accelerometer only data.With 303AGR e-compass I can easily configure the filters so a low pass filter can be set up in no time.With LSM6DSL I am a bit lost on where or what filter I have to setup in order to achieve the same (a extremely low-pass filter, below 1Hz).Thanks!

Hello. I am evaluating STEF01 for a PSU application. I am trying to calculate the values for RH using the formula provided in the datasheet. But my calculation result for RH is not in line with chart given in figure 6 (page 8 of the datasheet). Referencing the chart, for a value of RL of 10K, and a required UVLO of 12V (=Von), I would expect RH around 60kOhm. But my calculation is far apart from expected value:FromRH = 1 / { [ (1/RL) + (1/333) / (Von-1) ] - [ 1/4500 ] } I get 16,703 Ohms with Von=12 and RL=10k:1 / { [(1/10000) + (1/333) / (12-1)] - [1/4500] } = 16,703Very obviously my calculation is wrong, but why? Please advise, thank you.NOTE: This question and answer originated from a customer support case which was handled by us. We regularly review support cases and add any helpful ones here for all to benefit from.

Hi,When using the 'setAction' function of the class Button, why can't I pass a callback object taking one more parameter than just the "const touchgfx::AbstractButtonContainer&"?Here's my CallBack object with its corresponding handler function:Callback<NumpadBis, const touchgfx::AbstractButtonContainer&, const int> _keyPressed; void keyPressedHandler(const touchgfx::AbstractButtonContainer& src, const int);And this doesn't work:aKey->setAction(_keyPressed);While it works just fine if I remove the "int" param.

Hi, I am learning how to use Uart and created a simple example project where I sent 'hello world'. i then use RealTerm to view this message. i have generated this project using CubeMX and it works however i flashed the board once and after that i cannot debug it again, although the board is still working and i can connect to realterm to view the messages. i get the error 'Error in initializing ST-LINK device.Reason: No device found on target.'i connected another nucleo board to the computer and flashed that. the same thing happened where after its flashed it become unresponsive in the IDE. I am using Atollic TrueStudio as my IDE. STM32F103RBKind Regards,Mike
