Solved

In every example which i have tested after second device disconnection it stops Advertising. After a short investigation i found that aci_gap_set_discoverable waits for hci_cmd_resp_release. I don't know if problem is with stack on CM0 or it is problem in STM32Cube_FW_WB_V1.0.0I need answer ASAP: i have to decide if this Product will be used in our new (quite big) project.Best RegardsWojtek

I downloaded the latest version available at ST site i.e. Ver 1.07. When I am trying to sync the project the error appears. Same happens with old version also. Kindly help.

Posted on July 02, 2017 at 05:34Hello,I recently migrated to STM32 Platform and I'm trying to learn all the Peripheral features without using Standard Peripheral Libraries. Problem Statement: I am not able to  get PWM output on  timer output channel 2 ( GPIOA1)  after configuring general purpose timer 2 of STM32F103c8T6 Micro-controller in PWM mode 2.My Configuration: Timer :              General Purpose timer 2Timer Clock:     72 MHzDuty cycle:        50%Frequency:       50 HzMCU crystal :   8 MHzI configured the GPIOA in Alternate function output Push Pull mode with maximum frequency not exceeding 50 MHz,  I connected an LED bulb to the GPIOA pin 1, but the LED wend on glowing without reduction in the brightness level. The LED was still glowing even after i performed a test with duty cycle set to 0. O

Compiling the BLE_SensorDemo sources in True Studio does not generate the same .hex as the precompiled .hex provided in the "Firmware" directory. The precompiled .hex works with the BLE Sensor app when loaded onto the BlueTile, but the .hex compiled from sources does not. When comparing both .hex files, they appear to be mostly identical except for about 200 lines of data at the beginning of the precompiled .hex that does not exist in the .hex generated in True Studio. It seems like there are either issues with some of the source files or project settings and it is not clear to me what needs to be corrected.

I use stm32h743zi microcontroller and nucleo board.When I wanted to use ethernet communication on cubemx,LWIP is not enable.

I have been flashing ST with the Flash Loader Demo utility successfully for long time, directly to my PCB design. BOOT0 pin is high, everything around the STM32 is quite (no activity on peripherals connected). Reset properly connected to a Resistor with a small Cap.I try with a second PCB board and got the same issue. Googled the issue, read the Q&A, Try the CubeProgrammer, try the FlashLoader demo and try bootloader commands using a serial terminal. All tests with some interaction but unable to flash a new firmware.Flash Loader demo: It connects, shows "Target is readable. Please click Next to proceed. "remove protection" button is disabled. Next screen No target list, PID 0x45 (correct) BID: NA and version 3.1. Can't do anything more here. Flash Loader is not useful anymore after this point.Manual bootloader codes: Sent the 0x7F and received the ACK, Sent the 0x00 0xFF, received the proper answer (1F 79 0B 31 00 01 02 11 21 31 44 63 73 82 92 79) , Just in case sent the readout un

Hi everybody!I working on a simple project but with some sensors and co.I'm newbie with the STM32 and I want to try to port the project from the ATmega2560 to the STM32.But witch chip? I need :> SPI for an TFT screen 2.2" (ILI9340C or ILI9341)> SPI for a MicroSD Card> BMP180 sensor> 2 pins interup> 3 indepedants Pins PWM> 2 ADC> RTC time> One Serial for bluetooth HC-05> One Serial for an GPS L80> One Serial for connect an external probe> 10 digital Input> 4 digital Output> min 72Mhz for the sreen> All pin in 3.3vQuestion :> Minimum 64K of program space ?> Flashing the MPU directly with the USB port ?> Possible to program all from the Arduino IDE ? ( with the right card )Thanks! =)

831/5000I've created a board using the STM32F405R6T6.I am experiencing some problems with the card, after I record the firmware on the microcontroller, withdraw the power and reinsert, the firmware only starts to run when I press the reset button.In the debug it works, I record during the debug and it is already running, but when I save the card in release mode there is a need to press the reset button.I thought it might be something related to the bootloader circuit, or even the proximity of reset capacitor, I've attached the circuits below, if someone has already gone through it or has a hint how could solve the problem, I'll be extremely grateful.Sometimes during recording it also gives the following error "error erasing flash with vflasherase packet". Sometimes the error disappeared when activating boot, but not always.SOLUTION: Thanks for the comments, I found the problem. I currently have a switched source (L7981A) that converts the input voltage. The time for the voltage to go f

With Cortex M0+ (BLE) running, how Cortex M4 writes data on flash ?The reference manual says during flash writes all acess are denied.

To implement something like iconview in emwin,I created a​ Custom container,consist of a image and textarea. name as a icon.Then,create 2 screen .The screen1 use SwipeContainer ,whitch add 12 icon.Q1:How do I determine which icon is pressed?Q2:How do I switch to screen2 by clicking the icon?

Hi, everyoneI am using the STM32CubeMX for the first time.​I have a problem with clock configuration on it.But I do not know why the problem is occurring.I need help.Best regards,

Hello everyone, I configured TIM1 for pwm. I will use CH3 and CH4. CH4 works well, but CH3 does not work. Sometimes when I load program first time CH3 works, But When I turn off the power and then turn on power CH3 does not work. Is there anyone who has any information about this topic ? Thank you.

Dear Experts ,basically i am a embedded engineer but i don't have a knowledge in signal processing area, so i need your help for design UHF rfid reader for long range max 10feet is enough. anybody can help me to stay in wright track still complete the design. which is the best IC for my design?there is any example design, code for my need?How to start with out knowledge based on DSP.

Hello,I'm designing an application where a PCB with STM32F031C6 has to receive a minimum of 5 bytes via an half-duplex communication. Transmission is delimited by special character, ASCII is used. Ideally, the transmission would be composed by 3 data bytes and 2 delimiters (minimum).I don't properly understand if the HAL_UART_Receive_IT function suits my interest (i see it works with n° of bytes) and, more importantly, how the HAL_UART_Error_Callback is triggered. I don't understand the so-called "half transfer" callbacks too.The documentation is not helping me, i already read some PDFs...Anyone who understood enough to explain it to me?Thank you in advance,Mirco

Hello,an4013 Rev. 6 on page 21 writes:"The Counter Enable signal is generated by a logic OR between CEN control bit and the trigger input when configured in gated mode."while e.g. RM0351 writes:"Enable the counter by writing CEN=1 in the TIMx_CR1 register (in gated mode, the counter doesn't start if CEN=0, whatever is the trigger input level)."This contradicts and probably AN4013 is wrong and should read "logic AND"

Hi, I'm trying to use the STM32F7 to perform the FFT of a signal connected to ADC1 Channel 0 on my discovery board and I'm having trouble getting the TIMER 2 to trigger the conversion. When debgugging, it seems the DMA function isn't called at all. This is what my code looks like:void SystemClock_Config(void); static void MX_GPIO_Init(void); static void MX_DMA_Init(void); static void MX_ADC1_Init(void); static void MX_USART1_UART_Init(void); static void MX_TIM2_Init(void);   uint16_t uhADCxConvertedValue;   int main(void) { HAL_Init(); SystemClock_Config();   /* Initialize all configured peripherals */ MX_GPIO_Init(); MX_DMA_Init(); MX_ADC1_Init(); MX_USART1_UART_Init(); MX_TIM2_Init();   // Start Running ADC.   if(HAL_ADC_Start_DMA(&hadc1, (uint32_t*) &uhADCxConvertedValue, 1) != HAL_OK) { Error_Handler(); } // STart Running Timer: //Enable and start peripheral counter if(HAL_TIM_Base_Start(&htim2) != HAL_OK) { Error_Handler();

How does one convert:Raw angular rotation data to DPSRaw temperature sensor readings to degreesThanks :grinning_face:

I would like to pilot ST25R3911DISCO with labview (8.6). I have imported ST25R3911DISCOComm.DLL to LabView and I use GetST25R3911 from the DLL to get the handle and to redirect it to checkConnection for example. The problem is i do not know the data type of the handle ( UInt32, Signed, Array ,string?, pass value or pointer to value ?), so impossible to run the VI without an error.Anybody could help ?Does it exist a DLL, and .H without handle, like for CR95 ?Thanks,Bernard

Posted on May 22, 2017 at 19:51 Hi guys, I am working with the STM32L486 using the CubeMX tool and running into some SPI issue that I can't seem to figure out (I am new to ST chipsets btw). Specifically the HAL_SPI_Transmit routine takes to long compared to the fraction of the time the data is transmitted, as can be seen in the scope image below with yellow being the clock, blue being the data and pink the test point PA0_SET I wiggle (code below). The scope shows that theHAL_SPI_Transmit takes up to 4uS, which is ridiculous. Any idea how to speed this up close to the time it takes for the data to transmit (around 1.44uS)? Thanks, ED PA0_SET; Spi.Status = HAL_SPI_Transmit(&hspi2,(uint8_t *) &DDS_Cmd, sizeof(DDS_Cmd)>>1, 2); PA0_CLEAR; #hal_spi_transmit Note: this post was migrated and contained many threaded conversations, some content may be missing.

Posted on June 08, 2018 at 11:07Hello everyone!I`m trying to get CDC VCP working on STM2F407VET6 chip. I`ve created a project in STM32CubeMX (the latest version available), where I`ve set up clocks, enabled USB_FS_Device and USB CDC middleware. All the settings remained default, except for VBUS sensing, which was disabled.After this, I`ve generated code for Atollic studio, compiled and run in without making any changes to code. When I plug my device into PC (Windows 10 Pro x64 with latest updates), device configures and enumerates correctly, no errors was reported, and COM4 port is assigned to device. However, if I try to open this port with any terminal software (like Putty or RealTerm), they are reporting connection error ('the parameter is incorrect' in RealTerm`s case). On the device side, in this moment hUsbDeviceFS.dev_state is equal to USBD_STATE_CONFIGURED, and if I try to call CDC_Transmit_FS, then it returns USBD_OK on first call and USBD_B

Hello:I am using the STM32L433 device.In CubeMX, I am using ADC1 channels 5,6,9 and 15. Other than the yellow highlights, there are no conflicts. Under ADC Settings, for ScanConvMode, it only has "Disable" in the drop-down list. Why is this? Another setting needs to be first changed?
