Hello,I am assigning pins on a STM32F446 micro in cubemx.I would like to give a pin name to NRST, but it is stuck in a reset_state, and won't let me change it. It is colored differently than other pins.Is it possible to change NRST, or does it stuck like that to signify that it is the reset pin? Still going to use it as the reset pin, but not sure if that has to be specified somehow. I have the same exact issue with the BOOT0 pin. Is it possible to change the BOOT0 pin?

Hi,I am trying to use the PA2 and PA3 Pins among others as Inputs with Pullups. The configuration is correct, since I am comparing what is in the GPIO Registers for Port A with another input pin PA8 which works fine. I have seen that the same pins use serial and analog input, however I have not initialized serial and I guess to use the analog input you have to initialize it in the mode register? I am using the ADC but I have not configured these pins for analog input.Am I missing something, that is keeping me from using these pins?

Hi there,My application is battery operated, so I’m trying to wake up atmega328p from deep sleep from an interrupt though the GPIO pin from the sensor. I'm using Thresholds, "inside window". If any object ditected inside the range, to fire a trigger to wake up the host. Is such thing possible?If yes, could you give me some pointers or code samples please?My host platform is Arduino Pro Mini @ 8Mhz 3.3v.Thanks!

I need to get some PCBs made by JLC but they are continually out of stock of the STM32H743IIT6 which is my target processor. They do however have the STM32H753IIT6. Is there any reason I can't substitute these to run identical firmware?Thanks

Hi,Master:​​Platform: STM32F301K8U​As shown below in Figure 1, PA7 (MCU_14) is a video signal (As shown below in Figure 2), which contains the line sync signal (A area in Figure 2, fixed frequency, there may be noise)​and the field sync signal(B area in Figure 2). I want to distinguish the line sync signal and the field sync signal . My question is as follows:Question 1: What is the purpose of PA4 in Figure 1 through capacitor to ground and PA2, PA3 short circuit?Question 2: I want to use the comparator to compare PA7 and DAC1_CH1 and then use the input capture to measure the period to distinguish between the two signals (As shown below Figure 3). Is it feasible? I worry that if there is a lot of noise on the PA7, it may be difficult to distinguish. Is there a better solution? Ask the master for advice.​Thank you very much!​​ Figure 1 ​ Figure 2​ Figure 3

Hi guys, I disabled flashing core M7 in STM32CubeProgrammer option bytes to run just M4, but now I cant connect to the board and the tool says Error: No STM32 target found!. Is there some possibility how to reset the option bytes to again run M7?Thanks a lot!

Although SPC582B family has up to 7 FlexCAN modules, some units have only 3 (i.e. SPC582B60E1CD00X).Which 3 of 7 CAN modules are available in this processor?Since SPC5Studio shows 7 CANbuses for this processor, I don't know which I/O should I design for CANbuses.

Did someone has developed an i2c driver for SPC56EL70L5 that has no on board specific peripheral?Thanks

I am assigning pins on a STM32F446 micro in cubemx, and I would like to connect multiple chips to the micro on one spi bus.I would like each chip to be connected to a separate chip select pin, aka spi_nss.When I try to assign a second spi_nss pin, it deletes the first spi_nss pin.How do I assign multiple spi_nss pins?

Hello,I am assigning pins on a STM32F446 micro in cubemx, and I would like to read 2 encoders.When selecting Encoder Mode under the Combined Channels dropdown of the timer configuration, it automatically selects ch1 & ch2.Ch1 of the timer conflicts with other pins I have assigned (and can't easily move around).Is it possible to do encoder mode on a different pair of channels, say ch3 and ch4, or is there something special about ch1 and ch2?Also, what is encoder mode? I just presume I should use it to connect encoders, but I don't actually know how it works.

Following instructions @ https://www.emsyslabs.com/how-to-compile-linux-using-yocto-for-stm32mp1/andhttps://koansoftware.com/yocto-project-meta-layer-for-stm32mp1-by-koan/I'm led to believe that a qtcreator executable or script will be created which I can run on the host (Debian) to create and cross compile a QT5 app for STM32MP157.I'm new to QT but need to create a simple UI to run on STM32MP157, what am I missing ?Thanks in advance.

I used ST25R3911 and ST25DV16K for nfc.​I frequently get an error message about ERR_RF_COLLISION from rfalST25xVPollerFastReadMessage.​What is the problem?​As far as I know that RF_COLLISION is happened when the NFC reader has multiple NFC Tags neraby.But, I only used one tag(ST25DV16K). ​​

Hi, I have been following the STM32WB workshop, however the material seems to not fit to the current FW anymore.I need to read a sensor that is connected via I2C and send the results via BLE.I can get the sensor readings and output them via UART but as soon as APPE_Init() is called, the output to UART does not work anymore. I assume it is a problem due to scheduling, however the schedule.h file referenced in the workshop videos seem to not exist anymore, so I am stuck here.Does anyone have a working current example of reading sensor values in parallel to running BLE services, or an updated info on how to use scheduling?

Hi, I have 2 Nucleo boards: NUCLEO STM32F767ZI (F4) and NUCLEO STM32F446RE (F7).I'm using macOS 10.15.4 omn MacBook Pro 2017 with STM32CubeProgrammer 2.4.0 and stlink tools from brew (GitHub.com/texane/stlib).When I plug in F4 over USB-C to USB-Mini then neither Cube Programmer or stlink command line tool can find it. The device is powered properly and begins the blinking demo. But when I use F7 over USB-C to USB-Micro then both tools properly identify the board and the IC and I can program it over built-in ST-LINK.So would anyone know what might be the issue with F4? Am I using wrong cable (unfortunately it's the only one I have) or maybe do I need to do anything with the jumpers? I just took both boards from their boxes and plugged them in. And as described F7 works fine, but F4 is not discoverable...Any help would be appreciated. Many thanks.

Hi all,I'm currently using a nucleo-L031 board for some testing and I came across a weird RTC phenomenon.My goal is to do some ADC and send the data through USART, set up an RTC alarm for 10 seconds later, and then fall into stop mode.I have set up the main system clock to be drawn from the HSE, and the timer setup to use the ADC works correctly (i.e. correctly samples 10 samples over 1 sec, then send the data through USART), so I know that the HSE is clocking.I was able to achieve the RTC alarm and timing using the LSI and the LSE by adjusting the prescaler values correctly, but I was unable to do this using the HSE no matter the prescaler value. In fact, I even set the prescaler factor to both 1 and to 2^22, but neither had an effect on incrementing time which I tried to get using HAL_RTC_GetTime function.I'm going to use an STM32F051K8 custom board with this program later, and the MCU is only compatible with an HSE but not an LSE, and considering timining is important in this projec

I'm using the SPI peripheral on an STM32H743 as a slave. Is there a way to change the contents of the TX FIFO without resetting the peripheral? I need to always transmit a specifc byte at the beginning of a transaction along with other data, but the master may only request the first byte to analyze it (It is a status word indicating the repsonse is ready). At this point I need to refill the FIFO with the status word and the data.

Hi,I am using 3 ADC modules triggered with TIM3 to start in the same time.I read the result in the DMAx_Channely_IRQHandler function and for debug only I do a toggle in a GPIO.I have 3 DMAx_Channely_IRQHandler functions , one for each ADC with DMA and 3 output pint that I toggleAll of the outputs are showing me that the DMAx_Channely_IRQHandler function is called twice.I am using STM32G474 and STM32CubeIDE, with HAL.Why is this happening and how can I fix it?Thanks!!

hi during the debug of my program with UDE it gets stuck on osalThreadDelayMilliseconds i found in the forum that the problem may be a PIT configuration problem but i don't know how to set it.

Hi I'm a student, I'm trying to program for the first time a SPC584B-DIS developer board. I'm trying to set 6 pin as GPIO because I want to control 6 switches by setting the voltage to 0V for close and to 5V for open but I can't figure out how to do it.

Hi, For education purpose, I'm trying to create, compile, load and debug assembly projects with STM32Cube. Unfortunately, there are no built in options to do it. I noticed that I can erase on an existing project the main.c and create a main.s instead. It works, but I'd prefer to create an assembly project from scratch. Here are my questions :Even with this solution, I cannot access the external variables (.extern) RCC_BASE, GPIOA_BASE, etc... defined in stm32f446xx.h in order to program easily the registers. Is there a proper way to create an empty assembly project ?I also created a project with Makefile that I imported. I can compile, but in order to load or debug, i don't know how to set a correct configuration. A solution is to import that configuration from a C STM32 project, but that's no satisfying : it works, but I still have error pop ups all the time (Not able to get MCU/Board target).Thank you if you have answers to my questions !
