i bought your STEVAL-ISC004V1 together with NUCLEO-F072RB to configure to configure NVM over I2C. For this you have the tool: STSW-STUSB001Now i really tried to connect everything like the minimal description in the UM2254 of the STSW-STUSB001, but there is no blinking at all and no connection. I can upload the Nucleo_F072RB_STUSB_NVM_config_1.6.bin to the NODE_F072RB and i can read the DETAILS.txt file(Version: 0221 Build:  Sep 18 2018 11:09:21) but still no blink when i disconnect, connect the board, connect usb-b to NUCLEO-F072RB.Could you please update your software/usermanual or anythink to let me configure the PDO's ?Thanks

I am using STM32L432 with HAL library. I am programming ADC1 Channel 16 (i.e. PB1) as analog input signal. I have initialized ADC as Analog WatchDog-1 with Interrupt and without DMA, so that I dont have to continuously monitor my input voltage, if my input voltage goes out of certain threshold values, my AWD1 interrupt flag is set. Please find my initialization attached below.Now my problem is as soon as I start my ADC using "HAL_ADC_Start_IT(&adcHandle);"(WHICH DOCUMENTATION SAY "ADC Conversion by Interruption"), my EOC-End of conversion flag,ESMP-End of Sampling Flag is also set (almost immediately--I am not concerned about this flags) and My ISR is executed. And Never leaves ISR (As at the start of ISR I stop my conversion in ADC channel and before returning to main program, I again start my ADC conversion using HAL_ADC_Start_IT(&adcHandle)) otherwise my analog watchdog does not take new valueHow can I make my ADC to execute ISR only when AWD1 Interrupt Flag is set? (I guess

I need to get a copy of the STM32CubeF4_1.16.0 firmware and can't find the archived versions on your website. Can you please point me in the right direction?

As in the title, I've just updated to 4.27.0 and it insists on enabling Scan Conversion mode. This causes my ADC code to fail. Since there are no alternate options, why is the item in the menus?

Hello,​I am working on a project based on NFC energy harvesting application. I am using AMS AS3955 dynamic tag which offers this functionality with ST25R3911B as the reader. In the ST25R3911B datasheet, it says that NFC type 4 tags are preferred and nothing is mentioned about other tag types. Can ST25R3911B work with T2T commands(read/write)? If no then please suggest an alternative.​​PS: AS3955 can also work on ISO14443A​ standard, but its mode must be changed to tunneling.​Thank you in advance!​

In USART block diagram figure, "f" in "Transmit shift register" is missing, giving it a whole lot different meaning... ;)Besides this, the arrows from both "shi(f)t registers" to their respective data registers have incorrect direction. The LPUART chapters and the older STM32's chapters got this one right.This appears in several 'F0, 'L4, 'F7 RMs.(This one spotted by @jaromir sukuba​ )JW

Can I operate Nucleo-32 board with 3.3 V input voltage and disconnect on-board ST-link and connect external St-link?

I am working with SD card in SDIO mode. The current version of cube mx i.e, 4.27 is not working.

Hi,Just switched over to ST25SDK V1.3.0, and can no longer read my M24SR02 tag. After stepping through it appears I am getting a java cast exception during a Log call in file AndroidType4ReaderClass, function:public byte[] transceive(Object TAG, String commandName, byte[] data) throws STException (Line 61)java.lang.ClassCastException: com.st.st25sdk.command.Iso14443aCommand$iso14443aFrameMode cannot be cast to java.lang.StringLine 61:Log.d((String)TAG, frame);Causes java.lang.ClassCastException: com.st.st25sdk.command.Iso14443aCommand$iso14443aFrameMode cannot be cast to java.lang.StringBecause TAG is of class com.st.st25sdk.command.Iso14443aCommand$iso14443aFrameMode type.Thanks,Martin.

I am working on FreeRTOS on the STM32F777II. Was just curious, how can I configure TCM (CCM) memory for use and how can I force the linker to use this TCM memory only for selected variables declarations?

Posted on June 01, 2018 at 07:54I think I got the concept of how to jump to the MCU built-in bootloader but I never got it working. And often information is opposing each other.My requirement is simple and very common, hence I hope somebody has code at hand. I am fed up with trying and trying.I have a USB CDC connection, and enter commands there. One command should be 'boot to MCU bootloader' which would disconnect the USB and make the MCU appear in the DfuSeDemo tool. As if I manually disconnected the the board, pressed the Boot0 button and power it while button pressed.Source Code can be found here: https://github.com/wernerdaehn/CC3D-CableCam-Controller  Nothing special, standard memory layout etc.#stm32f4-dfu-usb-bootloader

Hi,I am using STM32F051R8T6 (of Discovery board). In my application I am using two timers: TIMER3 and TIMER15. TIMER3 is used to count number of pulses. Hence, I have used it as an external clock source based timer.TIMER15( based on internal clock source) is used to interrupt at certains ms(say 10ms) of time. I am toggling a GPIO pin inside the Timer15 interrupt, so that I can verify if the timer is right (by verifying the ON & OFF time of the GPIO pin with the configured TIMER15 time of 10ms).The problem is, when there is no external clock source for TIMER3, the TIMER15 interrupt works fine and the GPIO pin inside the interrupt is toggled at regular timer interval. But, whenever there is an external clock source for TIMER3 , the TIMER15 is affected(i.e the GPIO toggling inside the interrupt becomes irregular).Interrupt priority of TIMER3 is set to 1 and that of TIMER15 is 2.Why is this happening? Where I should I check for error?

Im using stn32f413zh nucleo board.I want to voltage to BJT from stm32 using DAC ,how can i do it or what to configure?please any thoughts.

Hi,I am trying to port a software written for STM32L486QX to my STM32L476RG Nucleo board. I have made the board modifications as described in the User manual, except I adjusted the capacitor values for a 19.2 MHz clock. I ran a small program to printf to UART using the HSE clock and it worked, I also measured with a frequency counter and was getting the correct 19.2 MHz within the specified tolerance. Now when I try to run the code written for the STM32L486QX it gets stuck in the loop where it's waiting for the HSE ready bit. Is there any difference as to the location of this bit for these two CPU's? Or is there something else that obviously jumps out? Thanks in advance for your answers

I am trying to configure the CR95HF (using either CR95HF.dll V0.9 or V1.2) to communicate with an M24SR02-Y, with an eventual view to read/writing NFC Forum Type 4 NDEF files. All I2C coding has been completed for "internal" access to the EEPROM/NDEF files. I now need to get things going from the RF interface.I'm struggling to get information on the correct sequence of commands to be sent. In particular, the meaning of the various parameters and responses (e.g. the whole anti-collision algorithm) would be useful. The CR95HF datasheet gives examples (e.g I've tried to follow D.1.5), but I come unstuck with Anti-collision and RATS/ATS commands.I can see that once past these, the remaining commands are very similar to the I2C commands.Any help would be much appreciated!

HelloIs there a possibility to reduce the time gap between two consecutive SPI Frames? Background: I would like to use only the MOSI signal without the clock to send information to some addressable LED (WS2812). They just measure the time between rising and falling edge of the signal to determine the data. With gaps between the frames, the timing of the MOSI signal is destroyed for a MOSI without Clock usage.I have the following Setup:Atollic TrueSTUDIO for STM32 9.0.1 STM32F042K6T Nucleo Board, with internal HSI48 Clock CubeMx HAL (STM32Cube FW_F0 V1.9.0) SPI Configured with baud rate 3MBit/s, 16bit data size, transmit only, SPI Tx DMA, highes priority In the main programm I have a uint8_t array with values to send over SPI.uint8_t DataToSend[]={0xBB,0xBB,0xBB,0xBB,0x88,0x88,0x88,0x88,0xBB,0x88,0x88,0x88,0x88,0,0,0,0,0,0};In the main loop, I call the following functions: HAL_SPI_Transmit_DMA(&hspi1,DataToSend,sizeof(DataToSend)); HAL_Delay(1000);With an attached scope, I can mea

I was trying to figure out what datasheet says with the following sentence highlighted bold for STM32F303R8T6The PWM mode can be selected independently on each channel (one PWM per OCx output) by writing ‘0110’ (PWM mode 1) or ‘0111’ (PWM mode 2) in the OCxM bits in the TIMx_CCMRx register. You must enable the corresponding preload register by setting the OCxPE bit in the TIMx_CCMRx register, and eventually the auto-reload preload register (in upcounting or center-aligned modes) by setting the ARPE bit in the TIMx_CR1 register.Do we have to set the ARPE bit for a basic PWM generation .. ? I experienced setting or clearing it in debug mode but I can't see the difference , It still generates the same PWM wave form .In my application I will be working with a fixed PWM frequency with a variable duty cycle , and I don't know if I should set or reset the ARPE bit .. I meant basic by Edge Aligned mode .. But I want to know what it changes with Center Aligned mode ..

I can connect with JTAG via SWD and load a simple program but after load the system won't run to main. The chip seems to be stuck in some hardware system reset loop. Attached is an image of the nRST pin. I've gone through AN4661 many times and can't figure it out. Power rail looks good and I have BOOT0 strapped low, PDR_ON strapped high. Any ideas?

Hi All,I am developing an application for the STM32H753II using IAR toolchain, STM HAL and Micrium OS-II.Most of the linker script files in the STM32Cube example suite only specify DTCM RAM for data storage (addresses 0x20000000-0x2001FFFF). I have been using the stm32h753xx_flash.icf (with only DTCM region specified) file with no issues up until now. I now need more RAM space.I have been attempting to use the chip's SRAMs however each time I change the linker to place data there, my application starts crashing somewhere in the init to UsageFault due to a jump to address 0x0...EDIT: I've narrowed down the instruction that breaks. At the end of an OS function when it's supposed to branch to the calling function, the instruction POP {R0, R4, R5, PC} is executed which is supposed to branch to a location in flash but instead it branches to 0x00000000. It tries to execute code from there and ends up in a UsageFault. Hope this adds useful context.EDIT 2: Turning off D-Cache seems to solve th

Hi,I'm using the evaluation board STEVAL-IDS001V4M which has a STM32L152 mounted on.I'm having some trouble on the initialization of the UART2 peripheral.I'm using the ST library contained into the STSW-CONNECT009 packet.To initialize the UART2, I'm doing the following steps:>> RCC_AHBPeriphClockCmd(RCC_AHBPeriph_GPIOA); //activate clock on peripheral>> USART_StructInit(&USART_InitStruct); //initialize parameters (parity, stop bit, bauderate....)>> USART_Init(USART2, &USART_InitStruct); //initialize USART2 parameters>> USART_Cmd(USART2, ENABLE); //enable usart2Then I use the following function to send multiple times a character 'A' to my PC.void USART_SendData(USART_TypeDef* USARTx, uint16_t Data){ /* Check the parameters */ assert_param(IS_USART_ALL_PERIPH(USARTx)); assert_param(IS_USART_DATA(Data));  /* Transmit Data */ USARTx->DR = (Data & (uint16_t)0x01FF);}But nothing arrives at my COM port!What did I miss in the init

I've used a Nucleo-F410RB to develop my application. I'm now trying to minimally configure the chip (STM32F410RB) on a separate PCB breakout board (LQFP64 package) after studying the schematic diagram and specs in the Nucleo documentation. Sadly, I cannot get the separated ST-LINK/V2-1 to recognize the chip on my breakout. Have no problem getting the LINK to connect and program a separated Nucleo-F410RB.Could anyone validate that the minimal connections to the chip (for it to be recognized by LINK programmer) would be as below (also shown in attached minimal schematic):3.3V (VCC) connected to pins 1,13,19,32,48,64 (with 0.1uF caps as applicable)GND connected to pins 12,18,30,31,47,634.7uF (Low ESR) connected to pin 54 and GND10K resistor connected to pin 60 (BOOT0) and GNDSWCLK on CN7 of LINK to pin 49 (PA14)SWDIO on CN7 of LINK to pin 46 (PA13)NRST on CN7 of LINK to pin 7 (NRST)VDD_TARGET on CN7 to 3.3VGND on CN7 to GNDSWO on CN7 left unconnectedI have crystals as well

Where do you connect JTAG (e.g. TMS, TCK, TDO, TDI, NRESET) to the STM32F091RC? I can't find this anywhere in the datasheet (r4-1/17), is this supported?
