Solved

I want to send the numbers in order but it only sends the number 0 constantly. When I make the delay 100ms it only sends 0 and 1. When I remove the delay completely, it sends numbers from 1 to 30 in order.

Hi all,I am using MPU ref. STM32MP153F, do you say me what is the time that elapsed between a tamper is detected and the backup resister are finishing erased?And the backup SRAM?Thank you in advance

I'm writing firmware for a custom board using the STM32WB15CCU6E and am having trouble getting the BLE functionality to work properly. I have created a minimal project that gets BLE running, and have not changed anything in the STM32_WPAN section, so it's just running the default "Custom P2P Server".The device advertises and is picked up by Windows and Android, but connection attempts always fail. During a connection attempt, HCI_LE_CONNECTION_COMPLETE_SUBEVT_CODE is received (in app_ble.c) with a Status of 0, and HCI_DISCONNECTION_COMPLETE_EVT_CODE is then received immediately after with a Reason of 0x3E (connection failed to be established).Sniffing the packets shows that the master sends CONNECT_IND and then makes repeated requests with LL_FEATURE_REQ, but the slave never sends anything back. The slave then goes back to advertising a few seconds later.I've been working on this issue for multiple days now and am out of ideas, so would really appreciate some help solving it.

 Is it needed to do the learning on every device? Or can the library be used on all devices of the same class?

Hi ST,We bought a ST25RU3993-HEPV last year to evaluate the RFID chip and wanted to control it using SPI (see that question, where you already helped us). The master SPI is a Cortex A15.We managed to set-up SPI communication and to implement spiTxRx() to read/write registers (single and continuous read/write). We started to integrate others ST functions from the ST25RU3993 STUHFL SDK package v3-0-2-0 package, especially the st25RU3993Initialize function.Before doing anything, this function runs a selftest to check three things:SPI communication works (write & read 4 bytes in Modulator control register 1 register)Check EN pin by calling st25RU3993ResetDoNotPreserveRegistersWe did not connect EN pin to a GPIO for now, so the chip is always enabled. I replaced the OFF/ON of the EN pin by a Soft Init (83h) single command.Check that the IRQ line is working, by sending 24 bytes in FIFO register instead of the 48 announced, and waiting more than 40ms, to have a timeout triggered on ST25RU

Hi, I am working on SPC58NG84E7 bootloader. I have Bootloader code(at 0x00FC0000) with which i am using "FlashErase" API to Erase Flash Memory block at 0x00FF0000 with "-Os size" Optimization But its not working. Also, I tried putting breakpoint to the next line after erase, but breakpoint does not hit. Looks like its stuck in the execution.I tried all other optimizations as well but same result.Also, without optimization (NONE(-O0)) its working fine. Same result is for "FlashProgram" API.What could be the issue here?Please help me resolve the issue.

We are developing a IC card skipass Reader product for ski resort market. I checked TRF7961 from TI, but it can provide only 200mW output power. In the datasheet of ST25R3916, this IC can give up to 1.7W output power. I wonder these two are same index or not. I would like to know the maximum reading distance with ST25R3916. Could you give me some information or advice?If possible, we want a distance about 30cm. With TRF7961, about 15cm can be obtained. Thank you very much for your help in advance.

I just installed the CubeProgrammer and I'm following the Populate the target and boot the image guide. When I get to section 1.1.1.1.2.6 Populate the SDCard and click "Connect" I get this error: But if I execute this on the command line:sudo /opt/st/stm32cubeprgrammer_2.9.0/bin/STM32_Programmer_CLI -c port=usb1 -w flashlayout_st-image-weston/trusted/FlashLayout_sdcard_stm32mp157c-dk2-trusted.tsvEverything works perfectly fine. I get this: Is anyone familiar with that error on the GUI? If it works on the CLI it should work on the GUI too, isn't it?

Hello, I have issues when I tried to use my nucleo 32WL with Sigfox (working well with LoraWAN). I followed the steps proposed in the AN5480 : working well for that : However, in practice when I try to obtain my ID and my PCA throught AT command, the values are wrong ! (don't match with the one in the header file)The sigfox activation works only with the one in the header file (and not with the ID and PAC obtained thanks to AT commands)Thus, it seems that there is a problem in the sigfox credentiel provisioning but Cubeprogrammer said that it is a success...Best regardsLouis

I am trying to run simple program to output HIGH on IO pin of microcontroller STM8S003F3P6. I am using PB5 pin to output High. I am using 3.3v power supply and expect GPIO to output 3.3v when I set it HIGH but surprisingly I am getting 5V instead, below is the circuit diagram  Can someone help how to get 3.3v instead of 5V on GPIO output for above processor, is there anything wrong with above circuit?

Hi all...I am using a nucleo board and CubeMX ....I have an external interrupt which I can see on the logic analyzer. However when setting a breakpoint in code it never goes there?? I am set for rising edgevoid HAL_GPIO_EXTI_Callback(uint16_t GPIO_Pin) { if (GPIO_Pin == SPI_IRQ_Pin) ISR.SPI_WakeUp = T; }

Starting a new project using the STM32F767ZI (144 pin) chip. Project will have ethernet, can w/bootloader over can, and lcd/touchgfx.Looking at the demo kits all of them have SRAM and a large amount of non-volatile memory that is assigned to different memory regions for extra storage of images/etc.My question is are both memory types necessary for building a successful touchgfx application? We need non-volatile memory for data storage anyway, but as I'm putting together the first prototype schematics I'm trying to decide how much SRAM and external FLASH memory is needed. We will be driving a 7inch 800x480 display in RGB565 mode. There will be a few image assets, but none will consume a full 800x480 resolution. Not seeing any guides out there for figuring this out.

UM2552 has a paragraph 4.2.2: Send request messageA SINK must send a request message to ask for a new power level, the rest of the sequence is identical to AMS power negotiation. How and what should I do to start the process of renegotiation? How to send USBPD_PE_Request_Ctrl/Message REQUEST? Thanks.

Hi everyone,I'm facing some issues while trying to understand if (and eventually how) it's possible to use a different antenna using an X-NUCLEO-NFC03A1 evaluation board.I know I may just use the bare ST25R95 chip and then realize an impedance matching circuitry to it, but for timing reasons I'm trying to understand if it would be possible to do that with all that's offered with the NFC03A1 evaluation board.Still, I have some questions and doubts:1) Is it possible? 2a) if possible, how can I do that? In the ST25R95 datasheet is only reported the differential output impedance, but in the X-NUCLEO-NFC03A1 there is only a schematic with the whole matching circuitry after ST25R95 TX1 and TX2 pins, so it's not clear how to do that.In fact I have a custom antenna which is a MUST to be used for my application, and I need to use it instead of the one integrated in the NFC03A1.2b) If not possible, I found the X-NUCLEO-NFC06A1 which uses the ST25R3916 reader, which has an AAT possibility control

I experienced NEAI Studio license activation issues, can you please help ?

Hi,We build a IC board with STM32G0 and ST25 NFC/RFID tag. It use also an EMI (AN5248) (I²C, Timers are used on the STM32). Reading Tag is OK. But when generating noise(EMC test) on SCL and tag is detected at the same time, the system goes down. ??

Hi, I'm designing a board in which the communication between STM32 and the host is UART over LVDS. So RS232 transceiver is not used in the design. And we want to upgrade STM32 firmware remotely through the UART LVDS interface by the host. But according to AN2066 page 38, the hardware requirement to use USART is through RS232 transceiver to the host. https://www.st.com/resource/en/application_note/cd00167594-stm32-microcontroller-system-memory-boot-mode-stmicroelectronics.pdfI'm wondering if RS232 transceiver is necessary to use the system bootloader. Is UART over LVDS ok to use the system bootloader. Does anybody know the answer?Any response is appreciated. And thank you very much in advance. With best wishesJasmine

I am using your NanoEdge AI Studio Software for classification and I am looking at the FFTs displayed in the signals segment after collecting data.How, specifically are these FFTs generated from the raw data ? Also, what the units on the axis are as I am unsure what unit 'fs' is ?
