Hello, i would like to get the mem size and block size but when i sent the request nothing is answer by st25t95

Hello,For various tests and especially for certification, I like to put the ST25R39xx into a test state in which it generates a continuous unmodulated field or a field modulated with random data (similar to NXP's PRBS test).Is such a mode available?How can I access this mode? Ideally via the RFAL library.The ST25R3916-DISCO board is FCC certified. Can you share the project / code used for FCC certification?Thanks in advane,Michael

Hello everyone, I am working with uC STM32F7 (main board)NFC Reader ST25R3916 ( pcb NFC reader)NFC ST25DV dynamic tag (pcb NFC tag)My project is working with freeRTOS and I have been writing my code based in the FreeRTOS_polling project from ST25NFC_EMBEDDED_LIB_ST25R3916_1.3.0. At this moment I am able to read/write different NFC Tag registers from NFC Reader without problems. I configured the NFC Reader in FTM mode so I am working with the 256 buffer. Once I detected my card and the rfal process is able to exchange info I put the next code. int32_t nfc_reader_wr(rfalNfcvListenDevice *nfcvDev , uint8_t *message, uint16_t len) {   ReturnCode err; static uint8_t tx_buf[200]; uint8_t *uid;   /*TEST WRITE*/ uint8_t rxBuf[ 1 + DEMO_NFCV_BLOCK_LEN + RFAL_CRC_LEN ]; /* Flags + Block Data + CRC */   // known data static uint8_t tx_msg[66] = {0,1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20\ ,21,22,23,24,25,26,27,28,29,30,31,32,33,34,35,36,37,38,39,40,41,42,43

As per SBSFU memory mapping details, to download application remotely, we need to define ACT_SLOT, DNLD_SLOT and SWAP_AREA range.What is the typical size of swap_area ??For STM32H753, as we have 2MB Flash only and One Sector 1 127 KB, is reserved for Secure Boot, Then what is the maximum size of Firmware application we can store ??What is the limit on Application size ??

Could the BAF_BYPASS field in the BAF configuration DCF register by modified by the user.If yes, under which module can I find it? I'm unable to find this in Lauterbach debugger.If no, how can I skip the BAF section during the bootup? - My device has pre-programmed BAF region.Thanks!

Could you send us the datasheet of L9966, we want to know the difference of L9966 and L9966CB. Is L9966 EOL?

hi, I would like to know if it is possible to read mcu SPC56EL60L3 with usb / uart adapter with software SPC5 FLASHER?

I am working with a SPC582B60E1 64 pin Flat pack chip. I am trying to program GPIO11_INT24_PWM16_CAN4SYS1_RX_WKPU pin 53 as a PWM output. But I am not sure if it is even possible. I consulted the SPC5 LLD Drivers for RLA components document for PWM low level driver and in that section of the document has a diagram showing the physical and logical channels. I took a screen shot and attached it for reference. It shows that that of the eMIOSx channels, that channels 8, 16 and 24 do not have PWM Drivers. So does this mean it is not possible to set channels 8, 16 or 24 as a PWM channel? If they can be set to a PWM, could you include a code snippet to set it up? Thanks,Steve Lam

Hi. What are the differences between them?

Hi,I'm trying to program a Connectionless Observer that scans all ADV_NONCONN_IND adv events, but the hci_le_advertising_report_event() callback isn't called.

Hi ST,We are currently adapting ST code into a Linux device driver and we have some issues with the Gen2 Select option: We are able to:Perform inventory rounds and list all the tags present in range of the antennaRead/Write EPC, TID and USER data when finding a tag and getting its handle during the inventory.Send a Select command to select only one tag by its EPC with startTagConnection function.After selecting the tag, we can call gen2AccessTag function and we are able to retrieve the tag handle 100% of time, but when trying to read data from memory banks just after that, we succeed only 5% of time (95% of time we get a ERR -33 (chip no response), or a ERR -35 (err chip preamble)).More details about the code:For each tag we want to select, we set the selParams global variable accordingly:selParams[0].mode = STUHFL_D_GEN2_SELECT_MODE_CLEAR_AND_ADD; selParams[0].target = STUHFL_D_GEN2_TARGET_SL; selParams[0].action = 0; selParams[0].memoryBank = STUHFL_D_GEN2_MEMORY_BANK_EPC; memcpy(sel

Hi,I want to program a connectionless observer to scan events, but the hci_le_advertising_report_event() callback isn't called.

STM32F301R8T6(Master)M95160-WMN6TP EEPROM(Slave)Low Level driversI've been trying to do a basic SPI EEPROM test based on the STM32F30x_DSP_StdPeriph_Lib_V1.2.3 SPI EEPROM example. Have finally gotten the write to work correctly but when we begin the read back from the EEPROM we see an extra three bytes of zeros in the receive buffer. The SPI bus analyzer shows the correct data coming out of the EEPROM chip so it seems that the RX FIFO still has data in it from the three read command bytes sent to the EEPROM(0x03, 0x00, 0x20, read command and address.) I've tried code examples from this site for flushing the RX FIFO but when running at full speed(i.e. not stopping in the debugger) there still is an extra three 0x00 getting into the receive buffer.When stepping in the debugger as we enter the flush function the SPI3->SR register shows a receive buffer not empty(RXNE) and a FIFO reception level(FRLVL) of 0x3(FIFO full.) After a single read of the SPI3->DR register the RXNE clears an

I am programming on the STM32L4R9I-EVAL dev board, but my project is configuredfor the STM32L4S9AII6. I am clocked at 120MHz.I have been fighting the following bug off and on for about 3 months. I queried for help on this a couple months ago and thought I had resolved the issue.https://community.st.com/s/question/0D53W00001PxcHZSAZ/can-you-have-too-many-peripheral-init-functionsI think I fix the issue and then it randomly pops back to ruin my day about every 2-4 days. The problem first manifest itself in my project as I was trying to get a one-shot timer configured. Since then I have observed enough to be 97% convinced that this is an interrupt configuration issue with MxCube, but as I debug the code and analyze the auto-generated code by MxCube everything seems correct.The cycle goes like this. I have to make some change to MxCube for various reasons like deleting a mutex or queue from FreeRTOS or adjusting settings with DMA or ADC interrupts. The ADC and DMA interrupts that I crawled

The DMAMUX1 can trigger DMA requests through synchronization and within the tab of synchronization possibilities there is TIM12_TRGO (input 7). So here is my question do the bits MMS[2:0] in register TIM12_CR2 configure this TRGO (it is written that it is for slave timers, for timer1 there is a separate MMS register for the ADC)?

Hello, I have a problem with programming EMMC through USB. Everything seems to be ok but when in U-Boot USB change from DFU to Gadget on Linux side everything stack (lsusb - stack). Of course, programming processes interrupt as well. I'm not sure where I should look for a malfunction. After the system boot-up USB gadget works normally I'm able to login to the board through USB. So from a hardware point of view, it seems to be correct or maybe not. When kernel boot-up and the system starts there is no switching activity on USB just load the Gadget driver and start USB and it works. I'm not sure how the switching process on USB in U-Boot works.   Part of my schematic is very simple So USB-C-ID is connected to PA13, with no connection to VBUS on the processor site. Maybe this VBUS is a problem or maybe the problem is in dts.   Please suggest to me something where I should start. Thanks

I want to send ADC data to the PC using BLE.The ADC data is directly connected to the DMA,So, sending DMA data is also fine.Is there any example or source code for it?I'm using the Nucleo-WB55 board.

I am using an STM32F429 Nucleo 144 and the Ethernet interface to run an Azure Iot client.Using STM32Cube IDE version 1.8.0NetxDuo versios 6.1.7Nx_SNTP_Client Sample projectI have combined this example with NetxDuo's sample_azure_iot_embedded_sdk_with_retry.c Once the IP address and SNTP server is connected (time is sync'd) I start the Azure client thread.My code is not able to successfully connect to the iOT hub. The call to mqtt_client_secure_connect() eventually returns the generic NXD_MQTT_CONNECT_FAILURE (i.e. 0x00010005 from file nxd_mqtt_client.h). The response code is generic and does not help with further debugging. Is there some additional logging or method to debug this. Here is a snippet from the console outputNx_SNTP_Client application started..

I have problems detecting a falling edge external interrupt. I can see with the tester the signal changes from 3.2v to 0v so its produced but the the interrupt is not generated. Could the 3.2v instead of 3.3v the problem?Signal is oscillating 3.19-3.20 all the time. Thanks

Sometimes an image tells more than a thousand words:As you can imagine, the dots shouldn't be shifted to the right as on my display (there is an offset on the x-axis)This is my very example template (lots of buttons to test my touch).I use the STM32F469 controller and my display is a ILI9881.When I use the same display with the STM32 Disco Techstar Board everything works fine.I have no reference where to look for my misrepresentation.I appreciate your helpCheers Jimmy

Hello,I have experience using Bluetooth classic profiles: SPP and A2DP.Started using STM32WB and I understand it doesn't support these two above profiles, it only has a stack for BLE. Is this correct?Can I use STM32WB with SPP and/or A2DP, if yes - how? if no - what profiles supported by the STM32WB do you recommend (to replace SPP and A2DP)?In addition, I've noticed ST has Bluetooth devices of series BlueNRG and SPBTLE: what is the difference between these two and the STM32WB?Do they support SPP and A2DPThanks,Jig

Hi ST,We bought a ST25RU3993-HEPV last year to evaluate the RFID chip and wanted to control it using SPI (You already helped us with that question and this one). The SPI master is a Cortex A15.We are currently adapting ST code into our newly created Linux Device driver. We tested the driver to read/write registers, the IRQ is working properly, and the selftests done by ST st25RU3993Initialize function are OK.However, when we try to read a tag using inventoryGen2 function in evalAPI_commands.c file, we can't manage to have more than -17dbm in output of the spectrum analyser. We can see that we are emitting at the good frequencies (Europe profile), but the output power with the internal power amplifier are nowhere near the experiments we did with a non modified EVAL board (-2db).Currently, here are the calls we do to initialize and run a scan:Note that spictx is just the context of the 25ru3993 device to be able to communicate with it by SPI./* Initialization */ initializeFrequencies();
