Why there's no 480..500MHz variants of H5, like in the H7 line?  

We would prefer to not use SPI to interface to a NFC reader as we are I/O and peripheral constrained here.I didn't see I2C as an option for any of the ST25R95, ST25R3911B or CR95HF. UART is an option for the CR95HF, but it is not available for it's successor product the ST25R95.So our interface requirements are steering us towards the CR95HF. Is that my best choice here?

Hello all,I'm currently implementing a double async circular buffer on a STM32L432KC Nucleo board. In order to increase the flow speed of the data leaving the buffers, I'd like to change the FLASH wait states (i.e. set the wait state value to 0). The ST documentation mentions the ART accelerator but does not provide enough details... I've also noticed a few code lines referring to wait states in the HAL_Init function.Could someone explain how to implement that and which file(s) to modify?I deeply appreciate your help!

Hello,I'm trying to set up the two interrupts on the LSM6DSOX, INT1 and INT2 to indicate Single and Double Tap events, respectively.I'm able to make both events trigger their respective interrupt, but would like them to be completely separate.I think I need to implement a delay on the Single Tap, to ensure it doesn't operate under double tap condition - it currently operates twice for a double tap!Is there a way I can do this inside the LSM6DSO, or must I differentiate the interrupts in my microcontroller?  WriteRegister( LSM6DSOX_CTRL1_XL, B01100000 ); //Set ODR to 417Hz? WriteRegister( LSM6DSOX_CTRL4_C, B00100000 ); //Enable Tap on X,Y,Z WriteRegister( LSM6DSOX_TAP_CFG0, B00001110 ); //Enable Tap on X,Y,Z WriteRegister( LSM6DSOX_TAP_CFG1, B00001000 ); //Set X Threshold WriteRegister( LSM6DSOX_TAP_CFG2, B10001000 ); //Set Y Threshold + Enable Interrupts WriteRegister( LSM6DSOX_TAP_THS_6D, B10001000 ); //Set Z Threshold WriteRegister( LSM6DSOX_INT_DUR2, B01111111 ); //S

Hi everybody and thanks in advance for the support.I have a ST SensorTile and I'm starting with the DataLog project to output data through USB port. I have correctly integrated MotionFX libraries and they seem to run, except there are just a bit of problems.What are the right units for time in MotionFX_propagate and MotionFX_update (param eml_deltatime). It seems it has to be expressed in seconds but in some samples you use a 20 constant defined. For instance: 20ms are 0.02f?What is the param eml_q_update in MotionFX_update? Should I put a float of something or it should remain NULL as stated in example/doc?What is the correct sequence for magnetometer calibration?MotionFX_MagCal_init at start (using sampleTime expressed in milliseconds?)MotionFX_MagCal_run in the loop, before the MotionFX_propagate/_update and until the MFX_MAGCALGOOD is reached?Can the MotionFX_MagCal_run be called every loop independently of the quality reached? What is the drawback?Is possible to know when to call

Hello I am using a custom design with the STSPIN32G4. Running open loop space vektor commutation works, but after a random amount of time the motor simply stops.Surprising is that if SPI is active the error seems to occure sooner than normal. Everything else seems to work fine (Control loop interrupt, main loop, i2c communication, SPI communication even the timer1 interrupt).No protection fault is being generated by the Driver. A reset and clear of the driver does not help.A software MCU reset seems to solve the Problem for a moment.Without a load it seems the problem does not ocure. So my thought is that it is an EMC problem. But why does it only effect the driver or the timer?Is there a recommended layout or a layout guide for the STSPIN32G4?I think since a MCU software reset solves the problem temporaly and I would assume that the reset does not affect the Driver. The problem is within the Timer1.Does anyone know how I could investigate it further? Should I reduce the FET driver cur

I use a glass for our VL53L1X sensor. But we found there is a crosstalk problem and have to use crosstalk compensation. We use VL53L1X ULD for our device. There are three functions about crosstalk.int8_t VL53L1X_CalibrateXtalk(uint16_t dev, uint16_t TargetDistInMm, uint16_t *xtalk);VL53L1X_ERROR VL53L1X_GetXtalk(uint16_t dev, uint16_t *Xtalk);VL53L1X_ERROR VL53L1X_SetXtalk(uint16_t dev, uint16_t XtalkValue);Could you tell how to use these functions to compensation crosstalk affect?best regardsDai Sai

I have an application where I need to use ECDSA to check a signature using the secp192r1 curve. However, I don't see a clear define for this in cmox_ecc.h. Is this supported under a different name?

I'm running the SBSFU on a STM32H7 where I can succesful upload a new application and it is starting. The application is running on an external flash.The question is, can I simply change the clock system settings to the applications need at startup or do the bootloader and app must have the same clock settings? Because the bootloader already sets the clock settings for it's own need. Can I usethe same clock settings as it would run as a standalone app?The second question is, the application is running azure RTOS which uses the SysTick as a base timer und the normal tick is incremented via TIM6. Is this possible to simply change the Tick sources or do I have to stop the current clock system inany way?I appriciate your help

I tried the same code on both microcontrollers, but STM32F103RET6 freezes with NVIC_SystemReset(); Can you help me please?

Edge-triggered interrupts had been used by us to identify various system states. However, it appears that the interrupts are now sometime erroneous and cause an undesirable state change. This led us to search for implementations where level-triggered interrupts would determine when a state would change.Note: STM32G041F6P6 is the MCU being used.

Hello team am Receving 16bit ADC conversion data to DMA in STM32H745i Disco in CubeIDE software. Here DMA interrupt is generating by default in software (i am disabled the interrupt in programming after that program counter is out of control) I dont want any ADC/DMA interrupt . DMA sholud receives the data contineously without any interrupt any solution for this ?

Hi,I try to combine STM32MP157CAA3 with DDR3L 8Gbits density. I modified cubemx to support 8Gbit memory and recompiled the Openstlinux mp1-v22.11.23 kirkstone.The problem is that DDR3 is detected in the first stage U-Boot but not executed 2nd stage U-Boot and reboot a few times after stack. The question is do STM32MP157CAA3 support 8Gbits density DDR3 memory in one chip and if yes what is wrong?Log from boot processNOTICE: CPU: STM32MP157CAA Rev.Z NOTICE: Model: STMicroelectronics custom STM32CubeMX board - openstlinux-5.15-5 INFO: PMIC version = 0x21 INFO: Reset reason (0x15): INFO: Power-on Reset (rst_por) INFO: FCONF: Reading TB_FW firmware configuration file from: 0x2ffe2000 INFO: FCONF: Reading firmware configuration information for: stm32mp_io INFO: Using USB INFO: Instance 2 INFO: Boot used partition fsbl1 NOTICE: BL2: v2.6-stm32mp1-r2.0(debug):v2.6-dirty(a1f02f4f) NOTICE: BL2: Built : 13:14:26, Nov 23 2021 INFO: BL2: Doing platform setup INFO: RAM: DDR3-DDR3L 16bits

Hello,Does sourcing the MCU clock from the ST25R3916(B) improve the RX sensitivity in card emulation mode? Is the strongest external load modulation obtained by setting the drain resistor (R301 in the X-NUCLEO-06A1/08A1) to zero?AN5768 states that the ST25R3916B has "advanced shaping of NFC-A, B, V, F modulation waveforms". Does this improve the card emulation mode as well?

Good afternoon,I would like to use the Sensor tile on which is running the en.fp-sns-allmems1 fw to directly record sensor measurements on the SD card. The idea is to power on the sensor tile, then dobletapping on the sensor tile to start recording directly on the SD card; once I dobletapping on the sensor tile, it stops recording on SD. In a nutshel, I want en.fp-sns-allmems1 to work like en.stsw-stlkt01 on the sensor tile without interacting with the BLE app, because I am interested in having quaternions recorded in csv and en.stsw-stlkt01 does not support quaternions. Should I try to (a) adapt en.fp-sns-allmems1 to do as I said above or should I try to include a library for computing and recording quaternions in en.stsw-stlkt01? If it is better to do (b) what library do you suggest ? Since I am new to programming at these level could you provide me some hints and examples, please ?

In follow up to my earlier question on reading Mailbox Memory from our iOS app, we are trying to pass the Read Msg command, but looks like this needs address flag set and UID needs to be passed. But when we try to pass the address flag and UID along with "AC" read command code, we get Stack Error along with Invalid Parameters error.The most recently released ST ios App seems to work fine with same Custom command. The source code in your site is not updated to reflect the latest changes you have made. So, we would like to get the latest source code and the code implementation specifically for Reading mailbox bufferShould we always check Message Buffer Length before calling ReadMsg (or) we can always 256 bytes of memory with null data returned for empty bufferCould you please also point to the section in the Data sheet to refer the different mailbox command implementations to understand which commands would need .address request flags along with UID

I'm having trouble with my STM32h757 processor. I'm trying to sample 2000 samples using ADC3+DMA1/DMA2/BDMA, but it's not working as expected. I set up the ADC to work in continuous mode and the DMA to work in circular mode with the address increment set to half-word. However, when I start the sampling process, the DMA doesn't increment the address and only the first value in the buffer is changing. I've tried defining the buffer in domain 1, 2, and 3, but it didn't make a difference in the behavior.IN addition, everything works fine when I use ADC1 instead of ADC3.Any ideas on what might be causing the issue and how to fix it?Thanks for your help.
