Hi,My project is SubGHZ Phy Ping Pong. In AN5568 the Rx consumption varies from 4mA to 10mA. In my project, the Rx consumption current from 8mA to 9mA. I want to reduce the Rx consumption. My configure below,Please recommend me some solutions.Thanks.

Hi guys, I'm a mechatronics student learning the basics of STM32s in my own time through the excellent series of guides by Vivonomicon. I'm currently learning interrupts, but my program seems to trigger a SIGTRAP fail when the interrupt fire.The code consists of main.c for the main loop and setup code, and nvic.c for holding the ISRs. There are a few header files for the volatile led_on variable and pin constants, It's running on an STM32413ZH Nucleo-144 board (I plan to use an 8080 LCD soon). All it does is watch the global led_on variable in the main loop, and on a rising edge on the on-board button (PC13) it'll toggle this variable (or at least that's what it's supposed to do)// Main.c   #include "main.h"   int main(void){ RCC->AHB1ENR |= RCC_AHB1ENR_GPIOBEN; // Enable GPIO bank B RCC->AHB1ENR |= RCC_AHB1ENR_GPIOCEN; // Enable GPIO bank C GPIOB->MODER = 0x1; // set Pin 0 to output mode // GPIOC is already in all input mode   GPIOB->OSPEEDR = 0x0

Using STM32F765VG6TR, every time I power on the MCU, the two DACs are supposed to be set to constant output voltages of 2.4V and 0.8V. This happens inconsistently - sometimes it works, about 50/50 success rate. A few notes:If it isn't working, an MCU reset does not fix it.There seems to be a correlation between how long I wait after power-down and power up and the DACs enabling properly. Waiting not too long and not too short seems to be the sweet spot (about 1.5s)This would lead me to believe it's a power sequencing issue with VDDA/VDD, but can't seem to correlate a specific start-up waveform with bad DAC behaviorHave reproduced the issue on two separate processors with different PCBAsEither both DAC channels work, or both do not work. Haven't seen one work and not the other.It didn't work on this try (DAC voltage in yellow):It did work on this try (see DAC voltage rise in yellow):I have tried waiting 100ms in the code before trying to run the DAC, no luck - which kind of makes sense

Apologize for IAR specific question, hope someone here can shed some light on my problem. I've tried to ask IAR support, but looks like they have a long weekend or whatever.​I have a bootloader at 0x08000000 and main app at 0x08008000.The bootloader initializes something for the main app so it must execute every time before the app.Pretty common thing, done many times with Atollic and CubeIDE.But I cannot debug this with the EWARM debugger.​When I set the main app as active and start debugger, it enters the main app directly from its reset handler, without going thru the bootloader. No matter how I define the reset method - "system", "core" "connect under reset".More to this - the reset button on the debugger toolbar has similar options - and none of these goes to the bootloader. Unchecked run to main - does not help.​ I tried to debug the bootloader instead, and load the main app as extra image. This properly starts the bootloader, but after entering the main app source navigatio

Hi,I've set up timer in PWM mode with circular DMA in CubeIDE.I would like to change buffer with halfcplt and cplt callbacks but i have no idea how to do that. I can't find any example on internet neither in documentation.Should i somehow register those callbacks or maybe there are some weak void functions that i can't find? I would be very thankful for any code example.Edit: I'm using stm32f407vg

This is a FreeRTOS related question. I am using FreeRTOS on the STM32L4S9AII6 MCU.How do I get access to the source code for the ulTaskGetIdleRunTimeCounter() function? All the IDE allows me to see when I attempt to open the declaration (F3) is this pseudo declaration found in task.h:uint32_t ulTaskGetIdleRunTimeCounter( void ) PRIVILEGED_FUNCTION;What a self-absorbed function. This must be proprietary information I guess. I need to know if this function does any blocking or disabling of interrupts. Is there a straightforward way to gather this information?

A regression was detected when a project is migrated to the latest STM32CubeMX v6.6.0. The following source files got removed from Core/Src folder after the migration.system_stm32xxxx.csysmem.csyscalls.cTo avoid this issue, please apply one of the following workaround:Delete .mxproject file before performing project migrationMove or copy the whole project in another location before project migrationWe are working on a patch release for MX and IDE in which the described issue will be fixed. The patch will be available soon. We apologize for the inconveniences.

Why I get \0 at the end of the transmission?I imaging the \0 is a NUL termination character but I have seen from the terminal that sometimes is not received or arrives with a big delay.Could somebody tell me anything about it?Thanks in advance.

Before that there was STM32CubeIDE ver1.4.0 STM32CubeMX ver6.0.0 everything was fine.Installed STM32CubeIDE ver1.5.1 and STM32CubeMX ver6.1.1, there was an error when connecting USB_DEVICE.Tried creating a project from scratch with nothing but USB_DEVICE. Gives an error message.What to do?

Hi all,I'm trying to read and write values to an STmicro tag(ST25TA02KB-D,  ISO 14443-4) using the X-Nucleo board from a python program. I've tried a number of approaches(waveshare pi hat, standalone PN532 modules, using libnfc and adafruit libraries, to list) but none really work and it's honestly a little out of my depth. Currently I've built the Linux nfc polling demo included with the X-Nucleo board, but even that fails to run(see attached)If I had resources or python examples using any of these systems, I could probably figure it out, but all the support I've found seems to apply mainly to mifare classic cards.If anybody has experience or pointers for any of this I'd be quite grateful to hear it!

I am trying to make SPI6 work with BDMA I see that transfer completion flag set in BMA ISR but SPI registers i don't see EOT bit set. I don't see any data coming from MOSI line of SPI6. Please help me know what is going wrong. There is no error set in any of the registers I have attached a screen shot of BDMA and SPI6 registers. I am using BDMA channel 0 for Rx and BDMA channel 1 for Tx.

The application is to measure the temperature of the liquid inside a container.

Hello everyoneI am trying to use the crypto library to perform an AES CCM encryption decryption. I am using an STM32F423CH MCU. The frames I am receiving are comming from other system and the authentication is always failing.I implemted the validation scheme that appears in the NIST Special Publication 800-38C for CCM. //FROM THE EXAMPLE IN nvlpubs.nist.gov const uint8_t key[] = {0x40, 0x41, 0x42, 0x43, 0x44, 0x45, 0x46, 0x47, 0x48, 0x49, 0x4A, 0x4B, 0x4C, 0x4D, 0x4E, 0x4F}; uint8_t nonce[] = {0x10, 0x11, 0x12, 0x13, 0x14, 0x15, 0x16}; uint8_t header[] = {0x00, 0x01, 0x02, 0x03, 0x04, 0x05, 0x06, 0x07}; uint8_t data[] = {0x20, 0x21, 0x22, 0x23}; uint8_t outputData[40]; uint8_t outputTag[8]; uint8_t recoveredData[32]; int32_t outputLength = 4; int32_t outputTagLength;     volatile uint32_t error_status = AES_SUCCESS; AESCCMctx_stt AESCCMctx; AESCCMctx_stt* AESctx = &AESCCMctx;   AESctx->mNonceSize = 7; AESctx->mKeySize = CRL_AES128_KEY; AESctx-&gt

I would also like to clarify whether there is support for the multi-zone VL53L3CX sensor? Do you have code samples or libraries for tap / double-tap detection using VL53L3CX?

Hi, The STM32Cube_FW_G4_V1.5.0 software package only have the the Buck Voltage Mode example. Where to find more applications examples for the B-G474E-DPOW1 board?

Hi,I am developing a program with the nucleo STM32G474RE that passes the ARR,CCR1,CCR2 values to TIM2 after some measurements made with another general purpose timer.However something weird occurs since when I look at TIM2 registers the ARR,CCR1,CCR2 values are correctly set but the TIM2 CNT seems to not care about the ARR value and it keeps counting.Any idea about why this is happening?

I have been looking in the documentation and break frame gets mentioned but cannot find whether is possible to disable the SBK.

Can anyone confirm if it is okay to supply the RF switch directly from a general purpose output of the STM32WL? This way I could control when the switch is working or when the antenna is isolated (off) from the circuit.I see in the datasheet for the STM32WL that "The GPIOs can sink or source up to ±8 mA, and sink or source up to ± 20 mA (with a relaxed VOL/VOH)". While for the RF switch the typical supply current is of 65uA and a maximum of 110uA.Seems that it should be okay. Could anyone that has done this or anyone with the knowledge confirm this is a good practice?Thanks and best regards,Asier
