Solved

Hi, I have been using PWM with DMA in one project with register-level programming, there i could find the RAM usage was around 28% and the ROM usage was hardly 0.5%. The similar application project when i tried with using HAL API's, I found the RAM usage was 6% and ROM usage was 3%. So i don't understand how there is so much difference when i use HAL over register level programming. At the same time using more of RAM is better or utilization of ROM is better?

We have a design with a menu implementation that uses texts in multiple places with potentially different typographies (the translated text is used for menu entries, headings or keyboard edit screens). Example: We have a parameter "Modbus Address" which has a menu entry with "Typography 1". When entering the menu, the keyboard pops up with the title "Modbus Address" with "Typography 1 bold". The issue is that the TouchGFX generator only generates the glyphs for the selected typography of the text resource but not for other typographies the text can be potentially used with. Now with the use of wildcard ranges this is easy for latin and other character sets with a relatively small number of character. But with chinese or similar languages, I would need to include >20k chars in the wildcard ranges in order to have all characters at hand which bloats the image to 10x the actual required size.Is there a possibility to solve the issue other than having a translation text multiple ti

Hi,   I have been using STM-STUDIO-STM32 for moitoring the real time variable while motor running without disturbing the program.  MCU used - Stm32F103c8t6 Debugger used - st-link v2 Software used - Stm-stdio  - The stm-stdio is get stopped while debugging and ended up with  showing the following error code: ''Acquisition stopped after 10 consecutive communications error'' @while motor is on loaded condition. - @Motor no loaded condition stm-studio seems fine. - Does any other software or debugging tool (for stm32) is available to monitor the real time variable for motor control.      

Hello everyone. I need help with single pulse mode stepper motor control. I am using motor control driver tb6600 and nema 17 stepper motor. Can you help with this?

Hi All,I am trying to get my Nucleo-U575ZI-Q to receive low level USART data using DMA. I have set it up to be a circular buffer in the IOC file but everytime I receive 1024 bytes for example after that it won't receive anything.When I call LL_DMA_GetBlkDataLength it gives me the space in the DMA buffer left and once it hits 0 it stays at 0. Instead of rolling around back to 1024. Attached is the settings for my USART1 Rx using DMA channel 0.Any other info required please ask.Thanks. 

Is there any way to store SVG images in external flash, similiar to how PNGs can be stored there?

I'm working on an audio-processing application with the STM32MP157F-DK2 discovery board. While evaluating the hardware, I built and installed the system using the distribution package. I used the following command to record sound via the 3.5mm audio jack:arecord -D record_codec -f S16_LE -d 10 /tmp/rec.wavAfter examining the resulting file, it seems like the board was unable to capture any sound from the 3.5mm audio jack input (which I connected to an AKG headphone that has a microphone). The only thing I can hear is some background noise (and it is still the case even if I use SSH to transfer the recorded file to my computer and play it back there, so it can't be the output issue).Any insight for recording audio on this board? Thanks a lot.

Hi All,I wanted to move from STM32F401 to a ECC enabled MCU and came across the STM32U575/585 series. Is it possible to in place use the QFN48 package for stm32u575 in place of stm32f401?. The pinouts/ports/power pins all look to be the same. are there any red flags?Please help with your expert advice!Regards,Nilav

HelloI want to build an In-Ear Monitor system for performing music live. This system gets an audio signal from a sound card. Transmits it wirelessly (around 865MHz) to a bodypack receiver and plays the audio with virtually no delay.I stumbled upon the NUCLEO-WL55JC1 Development board, which I thought may can do what I need on the RF and DSP part.I was however curious if anyone can tell me if I can connect two units, make a digital modulation, transmit from one unit to the other, demodulate the signal and play it from an audio unit with virtually no delay. I'm hesitant about ordering a couple of units as I think their intended purpose is less critical about small delays. :)Thanks in advance!- Kenney

hello?I am trying to perform BLDC position control using STSPIN830(X-NUCLEO-IHM16M1)+ NUCLEO-F072RB and MotorControl Workbench 6.1.2.Position control is MC_ProgramPositionCommandMotor1(). It can be controlled with a function, but how should the go_home() function be implemented to set the origin?This function is essential for project progress.help me !!!Thank you in advance.

I’m working on a project that uses an STM32H745IIK6. Occasionally, 32-bit SPI read data was invalid. This happened in about one out of every two hundred reads. To track down the cause, I added a few lines of code to toggle a GPIO pin as a scope trigger.What I found was unexpected. Trace 1 is the invalid data detect toggle. Trace 2 is the SPI chip select. (firmware controlled GPIO pin) Trace 3 is the SPI clock. Trace 4 is the chip select for a second SPI device that uses the same port. Trace 2 shows that the misread was caused by a delayed chip select. And trace 4 shows that the chip select disable for the second device was also delayed.An interrupt routine handles the chip select and starts the SPI send/receive.void SPI2_IRQHandler(void) { /* USER CODE BEGIN SPI2_IRQn 0 */ LL_GPIO_SetOutputPin(GPIOB, LL_GPIO_PIN_11); // SPI2 CS2_N high, disable ReadData = LL_SPI_ReceiveData32(SPI2); // read LL_SPI_DisableIT_RXP(SPI2); // disable SPI2 interrupts LL_GPIO_ResetOutputPin(GPIOB, LL_GPI

Hello, I am trying to find reliability data (specifically MTBF and FIT) for the FERD20H100S. If anyone knows where to find it or could point me in the right direction I would be very grateful.Thank you,-M

Hi,On a STM32 F7, I would like to lock access to the FLASH_CR by writing a wrong key to the FLASH_KEYR register. Writing a wrong key results in a bus fault (disabling the bus fault raises it to a hard fault).Could someone help me with a way to write a wrong key to FLASH_KEYR and mask the bus fault? I do not want to mask all bus faults (just this once when writing the wrong key).__set_FAULTMASK(1);FLASH->KEYR = 0;SCB->SHCSR &= ~SCB_SHCSR_BUSFAULTPENDED_Msk;__set_FAULTMASK(0);This only works when stepping through a debugger but not in the regular cases.Any suggestions would be greatly appreciated.Thank you.

Hello,I am developing a USB PD sink application on custom board with STM32G0B1VETI am using periphery UCPD2. I followed AN5418 to set up eveyrthing in CubeMX and add the specified pieces of code.Hovewer, ithe USBPD stack doesn't seem to send or recieve anything on the CC1 or CC2 lines. I have confirmed with oscilloscope, data is flowing to the MCU CC2 pin, but nothing seem to happen inside the USB stack.This is as far as it gets:With a sniffer device, I can see the power supply sending source capabilities, but these packets are nowhere to be seen when logging the application.This leads me to believe, the USB PD stack isn't getting the data.Any ideas where to look for the problem? I have followed the instrucions and I can't see how this could be a electricall issue. Firmware package is STM32Cube FW_G0 V1.6.1Thank you for any help 

I was just told that I've reached a limit of 1000 uploaded images.Now what?JW

Hello, I connected the UNICO GUI but it did not work and did not allow me to configure the device. Please see the images provided below.  

HiI was wondering if there are any examples for using the Sensor Fusion Low Power Algorithm inside a LSM6DSV16X. I would like to retrieve the current Heading, Pitch and Roll information. Alternatively I'd also be happy with an example explaining how to get the Quaternion values from the SFLP. Anything regarding the SFLP would be nice. The examples do not outline any of the SFLP features (at least I was unable to find anything except the calls for directly manipulating the registers).

Hi,I'm not able to use the GUI (W7). The DFU driver is not detected and the guidelines to fix it are not clear.At page 5/32 the UM2517 claims:Enter “C:\Program Files (x86)\STMicroelectronics\ST25R3916_Discovery_GUI\Driver�? and install it.But the \Driver folder does not exist at all...Where's this driver? Please, could anyone clarify this?On the other hand the Method 2: ST-Link on next page does not work neither. Any hint?thanks in advance,gaston

Posted on July 27, 2017 at 15:43Hello,I am trying to set up CUBEMX so that it can support LCD display for the STM32F469i-Discovery board.Unfortunately I had no luck in making the correct configurations to enable the LCD display or find an example project for the STM32 ac6 or maybe a .ioc file with LCD setings.Is there anyone familiar with LCD on STM32F469i?What are the correct configurations?Thank you!#lcd #ltdc #stm32f469-discovery #cubemx #ac6 #ioc

What are the 144 pin MCU s available

Starting from this video (https://www.youtube.com/watch?v=CGUC1wqSLCE) I'm trying to write my bootloader for DFU from an USB stick. The code works but I would like to tweak it such that:if at boot an USB stick is detected, than start the update, otherwise jump to application (done and it works)at the end of the update, jump to the application (this does not work)I got it work the second point by adding a delay to let me remove the USB stick. But if the USB stick is still plugged in, then the "jump to application part does not work.I suspect that this is related some kind of USB peripheral initialization.Here is the zip of the project.

Hello everybody, We hope you are doing well.we planned to use ST25R95 chip to create a smart card reader that can communicate with all smart cards and java cards (MIFARE and NFC). we read in ST25R95 datasheet that this chip does not support write action in all standards(ISO/IEC). We know we can use PN512 chip that fulfills all needs we have.Does anyone know PN512 can be replaced by ST25R95?Can we have full read/write access to all tags MIFARE and NFC mode in all standards(ISO/IEC) by using ST25R95?Thanks in advance.Best regards.

Hi everyone,I have just discovered that I have multiple errors when I try to read more than 30 blocks, rfalNfcvPollerReadMultipleBlocks() function depending on the number of blocks I try to read.Firstly, I want you to talk about the TAG I am reading: - It is a ST25TV02KC NFC type5 - ISO/IEC 15693 (NFCV) TAG from ST - It has 320 bytes of memory and 4 bytes block-size.- With the Android app ST25 I can read all the blocks correctlyThe behavior I am seeing is the next:- I can read successfully from 1 to 30 blocks. - When I ask for 31 blocks, I get ERR_FRAMING (0x09) error. I don't understand this error... Could you kindly explain it to me, please? I have, also, searched in ST forum for this error, but I haven't seen any solution related to my issue.- When I ask for more than 32 blocks, I get ERR_RF_COLLISION (0x1D) error. Again, I don't understand why I get collision error because I have only one tag in the field of the RFID. Could you explain me this, also, please?Another t
