Hi,The file stm32l432xx.h defines SRAM2_BASE as 0x10000000, but the datasheet https://www.st.com/resource/en/datasheet/stm32l432kc.pdf says that SRAM2 starts at 0x2000C000, is this a typo in the HAL header?Thanks,Jacob#STM32L432​ #Hal​ 

where to download the data sheet for STM32 NUCLEO-F303RE board , please provide the linkNeed to know the register adress details of all peripherals and MCUs.

I have a product that needs to write parameters to Flash.I saw on the website and datasheet all tell me STM32F100C8T6 is 64K Flash,Flash 1K per page, total 64 page,the finnal page is page 63,however I made a fault I made a fault I write parameters to Flash of page 127,I found that 127 pages of Flash can save and store data.Does this mean that Flash has 128k can be program?​​

Hi, I'm really new in this world but I'm trying to read a NFC card with my NFC01A1 on a Nucleo L476RG but all the examples I found are only for writing on an android phone. Is it possible to read a NFC card with the NFC01A1 ? And if yes, how ? Is there an example somewhere ?

I generated a new cube project, included everything what nfc reader needed(like the sample project for 401), I modified the platform.h, the SPI is working, but its a bit confusing, because if I use HSI the reading is freezing in demoPollNFCA() - without any card. If I use the 072 with 48Mhz HSI the polling works fine but if i put a card in front of the reader I get a hardfault ISR.. So the ST25 init  succeeded, the SPI and the interrupts are working. Maybe there is some problem with timings, (like NFC's GP or SW IT..)

Hi,In my application I put the BlueNRG-1 unit into deepsleep with NO_Timer activated and it can only be awoken by IO12. When the unit is awaken by IO12 I check the wakesource and I confirm it was IO12 that has awaken the chip. Right after this I need to do a BLE scan by using the following instruction result = aci_gap_start_general_discovery_proc(625, 625, PUBLIC_ADDR, 0x01);The result code returned is 0x46 which indicates /** * @brief The requested operation cannot be performed by the Host in the current status. */ #define BLE_STATUS_NOT_ALLOWED ((tBleStatus)(0x46))I am not sure why it is not allowed ?The strange this is that this only happens when the unit has been awaken from DeepSleep. If I run the system normal I don't get this errorANDWhen my program runs the first time I do a scan as indicated above and it works 100% and then I go into a Deepsleep awaiting to be awoken by IO12.What am I missing?What do I need to do when I have been awoken from sleep?Please help as I have sitti

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

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?
