I am making a device that is to take pulse outputs which have been converted to wireless LoRaWAN signals, and convert it back again into a hardwire pulse output. For the receiving device, I intend to use a modem board PN 109990166 connected to an STM32L476RG. Is it possible to make a simple LoRaWAN server on the stm32F4 whose primary purpose is to take the wireless data and convert it to pulse output? If not, what other wireless protocols would be good for this application? The transmitter doesn't have to be LoRaWAN.

(A translator was used for this inquiry.)Hi,I am using the vl53l0x sensor.I would like to inquire about the detection range of the sensor.What value do you get when the wall you want to measure the distance against is tilted? (Refer to image1)What point distance do you get if the minimum length between the sensor and the wall is 100 mm and the maximum is 200 mm?I know that the maximum measurement distance of the sensor is 2M.I would like to know the range of the detectable area when the wall and the sensor are 2M away.(Refer to image2)Thank you.

Hi Guys I'm Trying to find stm32l073rz Nucleo board datasheet that contains the boards pin description, but I can't find it anywhereI have found those but when I compare the pin description in the first pic from: NUCLEO-L073RZ | Mbedwith the one provided in this datasheet:Datasheet - STM32L073x8 STM32L073xB STM32L073xZ - Ultra-low-power 32-bit MCU Arm<Sup>®</Sup>-based Cortex<Sup>®</Sup>-M0+, up to 192KB Flash, 20KB SRAM, 6KB EEPROM, LCD, USB, ADC, DACsI find the pins order is different..

Hi,I'm working on a hardware design using the STM32F765VIH and I am trying to connect a MT28EW128ABA1HPC-0SIT NOR Flash and IS66WVH16M8DBLL-100B1LI PSRAM to the FMC in muxed mode. I'm struggling to understand how the muxed connection should be made and although I've searched a lot I cannot seem to find any reference schematics for this.  Can anyone point me to reference material that could help me? Thanks,George Edit: Corrected NOR Flash part number, was previously wrongly written as part IS29GL128-70DLEB

Folks, I started off with the H573i discovery board demo as reference for the MSC + SD card (with ThreadX). I don't have the Discovery board since in my application I needed those CC1, CC2 USBPD pins for something else.  So I ran a board of my own (using the H563ZIT6).  I'm using just micro-USB B connector, not USB-C.I set up the project in Cube and pulled in all the segments from the demo for H573I.But in CubeMX I have to disable the UCPD in order to get access the two pins I need.I just left the USB enabled.But it seems that there is no USB library setup properly if the UCPD is disabled.Can someone tell me how to get the demo from the H573 to work if the CC1, CC2 pins are disabled in Cube and assigned as GPIO? I don't have to have the ThreadX but figured it might be helpful as my product develops.  Thanks!J 

Hi, the problem is very simple, yet I haven't seen any information about this case in the foro or anywhere.When trying to build the example proyect BLE_HR_p2p_Sensor which I think was already in the B-WB1M-WPAN1 board relesed to start cathing up with the FW I'm not able to do so.It doesn't mind if i get the example from the "STM32Cube_FW_WB_V1.18.0" or from the STM32CubeMX example BLE_HR_p2p_Sensor generation I always encounter the same errors: C:/ST/STM32CubeIDE_1.11.2/STM32CubeIDE/plugins/com.st.stm32cube.ide.mcu.externaltools.gnu-tools-for-stm32.11.3.rel1.win32_1.1.100.202309141235/tools/bin/../lib/gcc/arm-none-eabi/11.3.1/../../../../arm-none-eabi/bin/ld.exe: BLE_HR_p2p_Sensor.elf section `._user_heap_stack' will not fit in region `RAM1'C:/ST/STM32CubeIDE_1.11.2/STM32CubeIDE/plugins/com.st.stm32cube.ide.mcu.externaltools.gnu-tools-for-stm32.11.3.rel1.win32_1.1.100.202309141235/tools/bin/../lib/gcc/arm-none-eabi/11.3.1/../../../../arm-none-eabi/bin/ld.exe: region `RAM1' overflo

Hello everybody!I installed STM32CubeIDE 1.15.0 and I tried to follow the session STM32WBA5x workshop - 3:https://www.youtube.com/watch?v=BLs1KzC-s4obut STM32_WPAN is in grey; explanations say me to install other things, but it seems boxes insides other ones...I enabled RNG: STM32_WPAN is STILL in grey,I enabled RAMCFG: STM32_WPAN is STILL in grey,I enabled RF: now STM32_WPAN is active!Why is STM32_WPAN not already active starting from the example WBA55_P2P_SERVER?Thank you for the replyBR

Hello,I would like to get free memory on USB drive (64GB, FAT32) with FatFs library. Here is part of my code:  DWORD fre_clust, fre_sect; uint64_t free_memory; res_file = f_mount(&fs, "0:", 1); res_file = f_getfree("0:", &fre_clust, &fs); fre_sect = fre_clust * fs.csize; free_memory = (uint64_t)((uint64_t)fre_sect*(uint64_t)fs.ssize)/1048576;//MB  The problem is that f_getfree() always returns same value, even if data size is changed.Also I would like to say that res_file has return value FR_OK in both cases andIam able to write data on USB drive with FatFs. (Iam using STM32CubeIDE 1.14.1 and STM32H753) Does anyone know what Iam doing wrong?Thank you for your response.

Hello,we are developing IoT device for which we are planning to use STM32MP135D MPU placed on our custom SoM.To do test before SoM is ready, I have obtained a STM32MP135F-DK. There are some concerns about the 'factory programming' of such device.With the STM32MP135F-DK the method I have tried is to set all Boot switches (BOOT0, BOOT1, BOOT2 pins) to 0. Then the device boots into "Force USB boot for programming" mode, and the firmware can be uploaded using STM32 Programmer CLI running on PC. It works fine.As pic. 1 shows, also USART3 can be used for factory programming and that was the plan for SoM. Of course first I wanted to try it with DK. But unfortunately, the default USART3 TX and RX pins aren't accessible at STM32MP135F-DK GPIO connector. After research I came to conclusion that also USART6, UART4, UART5, UART7, UART8 are not accessible at that STM32MP135F-DK.1. Is my conlusion right? Can I somehow test factory programming using USART instead of USB with STM32MP135F-DK?2. Maybe w

Posted on April 19, 2017 at 09:27 Hello, I want to use DFU for update my program on the STM32L476RG. I use a personnal board. When I put BOOT0 to VCC, the Bootloader start and we can change the firmware but my system is on battery and I have no access to BOOT0 pin and RESET. So I want to jump in bootloader directly from software for that I have search the start addresse of system memory of the MCU -> 0x1FFF0000. So this is my code : #define USBD_DFU_APP_DEFAULT_ADD 0x1FFF0000 pFunction JumpToApplication; uint32_t JumpAddress; /*** **** some code HERE ***/ HAL_RCC_DeInit(); HAL_DeInit(); SysTick->CTRL = 0; SysTick->LOAD = 0; SysTick->VAL = 0; //_HAL_REMAPMEMORY_SYSTEMFLASH(); /* Jump to user application */ JumpAddress = *(__IO uint32_t*) (USBD_DFU_APP_DEFAULT_ADD + 4); JumpToApplication = (pFunction) JumpAddress; /** * Step: Disable all interrupts */ __disable_irq(); __HAL_SYSCFG_REMAPMEMORY_SYSTEMFLASH(); /* Initialize user application's Stack Pointer */ __

I have a STM32F405RGT6 on a custom PCB and are using a ST-Link/V2 ISOL in my computer. A USB-Mini is conencted to the ST-Link and from the ST-Link I use RESET, SWCLK, SWIO and GND to my STM32. I have tried connecting to the ST-Link with the STM32CubeProgrammer with the following settings:Port: SWDFrequency: 4000Mode: NormalAccess port: 0 Reset Mode: Software resetSpeed: ReliableShared: DisabledDebug in Low Power mode: ONBefore connecting I have updated the driver to the latest according to the STM32CubeProgrammer: Version: V2J43S7 After updating the driver I tried to connecting to the MCU and recieve the same error every time:Error: No STM32 target found! If your product embeds Debug Authenication, please perfrom a discovery using Debug Authentication(I have also tried with different settings and it gave the same error) I have tried following steps on the following guide:https://community.st.com/t5/stm32-mcus/how-to-solve-debugger-connection-issues/ta-p/49

Hello,I am working with the IIS3DWB for a vibration monitoring sensor, and have a few questions about the ODR (Output Data Rate) accuracy, hoping someone can help me.1. I know that on the datasheet the ODR accuracy is stated as +-1% typ, or +-2% Max.I want to know, does this accuracy specification include using the INTERNAL_FREQ_FINE register to correct the ODR (See page 45)? If we use the contents of that register is the tolerance considered more accurate?2. I am also curious if anyone knows the INTERNAL_FREQ_FINE register is set once in manufacture, or if the contents change over time. Should I read this register once or read it regularly to update my data rate correction.2.a. I know there is also a characteristic to describe the ODR change with respect to temperature. Is this characteristic captured in the adjustment provided by the INTERNAL_FREQ_FINE register? Or would it be beneficial for me to apply this correction in post processing?Thank you in advance to anyone who can help me

Hello eveybody.Before try to uss a motor with encoder drive by B-G431B-ESC1 board, need some setting ? Examples:Encoder A and B sequence respect to motor rotation CW or CCW ?Encoder phased to electrical motor phase ?Any Other ?

The KC chips made breaking changes to some configuration registers, but v2.3.1 of the ST25 Tag Editor has no option for the KC variant, so some configuration registers are read/written incorrectly.

Hi,I want to know by when STMicrolectronics is going to support STM32U0 series in STMCubeMX.-Sumit

Hey, I have a problem with the callback for FDCAN1. I am sending frames through ucandevices converter but the callback for FIFO0 is not called. The frames are definitely arriving, I added a test FreeRTOS and a task to receive and send frames to CAN1 and it worked very well, frames were received and sent back to the bus.I have NVIC interrupts set up, I fiddled with the clock for CANFD and speeds, also with no effect.Is anyone able to help me?I am sending my project as an attachment

Hello,I am currently Using STM32F779NIH6 for one of our application prototypes. Currently the internal RAM size is 512KB and based on our evaluation, for certain peripherals we need a higher RAM size ( Atleast 2X or 3X). Can you suggest any Controller from the High performance MCU family which can satisfy this higher internal RAM requirement but at the same in pin to pin compatible ? Thanks,Siddharth

Hi everyoneI'm currently using the NUCLEO-F429ZI development board. I'm planning to create a PCB using the STM32F429ZIT6, but I've encountered some questions during the planning stage.According to the datasheet, HSE_OSC is specified to provide 8MHz, and CubeIDE also indicates "Input Freq HSE = 8MHz." However, on the NUCLEO-F429ZI development board, the JFVNY 25.000 oscillator supplies 25MHz. I have verified that the SPI clock indeed derives from multiplying and dividing an 8MHz source, but when I measure the JFVNY 25.000 oscillator on the development board, it does indeed supply 25MHz. Why are these two frequencies inconsistent, or am I misunderstanding something?Referring to the Clock tree and considering, if not using the RTC section, is it possible to omit providing the external LSE_OSE?

Hello, I want to use X CUBE USB AUDIO examples in X CUBE IDE.After generating the binary code (without errors) and flashing the binary code via DFU, the card is not recognized as an audio device, I tried on all 4 projects. I unplugged USB, do reset, nothink change.On the other hand, if I generate for example the binary of another audio project: FP-AUD-SMARTMIC1, and flash it via DFU, the card is recognized as an audio device. Thanks by advance.

Hi,I have my master and slave applications running on NUCLEO-H563ZI Boards both of which normally receive/transmit  10 bytes of data in each SPI transfer. I use SPI in DMA mode.However, in one test case, master starts a SPI transaction for only 4 bytes i.e it calls HAL_SPI_TransmitReceive_DMA with Size as 4. So, my master sends clock for only 4 bytes even though the slave has 10 bytes of data. At this point, the Master receives 4 bytes but the HAL_SPI_TxRxCpltCallback on Slave is not called.I am doing a GPIO Pin toggle in the callback to denote completion of the SPI transfer which is necessary for my slave application. How do I abort the SPI communication in this scenario?I see there's a HAL_SPI_Abort_IT. Not sure how to use it. Appreciate if you would provide some insight on this.

Hi, guys, anyone has met such an issue?I was trying to generate code by CubeMX, and I also wanna generate USART1 IRQ handler but failed.here are my settings, anyone can help me with this?thanks
