Solved

Hello everyone,I am fairly new to embedded so bear with me. I am trying to understand bare metal programming.So basically I managed to turn on the LED on soldiered on the board (PA5) but now am trying to create a delay using basic timer TIM6. My issue is that the LED is barely turning on for a very brief moment before turning off. I think my issue lies in how I am configuring the prescaler and auto-reload register. I looked up online and it says that the default clock speed is 16MHz, but I did not configure any clock source.Here is my code down below which I used the reference manual to write: GPIOA->ODR |= (1<<5); // Turning on LED // Initialize TIM6RCC->APB1ENR|=(1<<4);TIM6->CR1|=(1<<0);TIM6->PSC=16000-1;TIM6->ARR=1000-1;TIM6->CNT=0; while(!(TIM6->SR & (1<<0))){}TIM6->SR&=~(1<<0);TIM6->CR1&=~(1<<0); GPIOA->ODR &= ~(1<<5); //Turning off LED  Thank you. 

I am going to rebuild STM32DDRFW-UTIL Firmware to do DDR Test on my custom hardware. I looked at this document: https://github.com/STMicroelectronics/STM32DDRFW-UTIL/blob/main/README.mdin section 1.2.3.3 Customization, it mentions about using STM32CubeMX to generate the DDR Templete (stm32mp2xx-ddr4-2x16Gbits-2x16bits-template.h). Unfortunately, I tried the device tree generation function from STM32CubeMx; there was no DDR templete was generated. Is there any instruction to generate the DDR templete?    

When using the VL53L1CB for ranging, we want to achieve lower power consumption by reducing the measurement frame rate. I performed the following two experiments:A 50ms measurement budget (integration time) followed by a 50ms waiting period.A 50ms measurement budget followed by a 100ms waiting period.I observed that the power consumption in both scenarios is nearly identical, with no significant difference. Using a photodetector, we confirmed that the ToF sensor's light emission time aligns with the measurement budget; a 50ms integration time results in approximately 50ms of light emission, confirming my parameter settings are effective. The power consumption curve shows that the power level remains high even after the ToF sensor has finished emitting light.How can we reduce the power consumption during the waiting interval between measurements (without shutting down the sensor)?If shutting down the sensor after each measurement achieves lower power consumption, what is the reason for

VL53L1CB的最低投资回报率配置是 4x4？我可以将其配置为 1x1 吗？ Translated : The minimum ROI configuration for the VL53L1CB is 4x4? Can I configure it as 1x1?

Hello!I am using the VL53L4CD TOF Sensor as sold by Adafruit. I am running it with the circuit patched together as described in the example file VL53L4CD_Sat_HelloWorld.ino, also with the exact code (the only change being the port number). I am using an Arduino R4 WiFi. When I start the unit up, it runs normally for a bit (<1 min), and then stops.Starting... Status = 0, Distance = 37 mm, Signal = 232 kcps/spad Status = 0, Distance = 38 mm, Signal = 234 kcps/spad Status = 0, Distance = 35 mm, Signal = 233 kcps/spad Status = 0, Distance = 36 mm, Signal = 230 kcps/spad Status = 0, Distance = 39 mm, Signal = 236 kcps/spad Status = 0, Distance = 35 mm, Signal = 234 kcps/spad ...I have an Arduino R3 Uno, and tested the TOF sensor using that, and it seemed to run endlessly.Based on reading around, I am guessing this has something to do with the resistors required for I2C connections and some builtin difference between the R4 WiFi and the R3 UNO, but I am not sure where I should start here.

hi, i am trying to attach a Touch Sensor header file  with touchGFX STM32TouchController.cpp file but it's showing error .the Touch_Sensor.h & Touch_Sensor.c file are include project file and further included via path location ( Properties ->General -> path.). 

I am successfully using all the SWV debugging functionality in STM32CubeIDE except for the ITM functionality, as described in UM1609 and in the advanced debugging videos on youtube from ST.I have both tried overriding the "_write " function in main.cpp or replacing "__IO_putchar" with "ITM_SendChar" in syscalls.c, but I don't see any output when using printf and ITM port 0 (described in video 4 and section 4.3.5 in UM1609).I have further tested sending output to ITM port 31, as described in video 5, but still cannot see any output.Some details and further questionsSWO is left unconnected - Do I need to connect the SWO to some other pin to make ITM work?I am running at 180 MHz clock speed - Is this too fast for ITM?Does it matter if I compile for cpp rather than c?Are there any benefits to updating an ITM port, like in video 5, rather than updating a global variable and observing the execution order by looking at a graph in a SWV Data Trace Timeline Graph or in CubeMonitor?Any further s

  Hi all, I’m using an ST25R3916 with RFAL on an STM32 and I’m trying to talk to an NXP NTAG 5 Boost (ISO15693/NFC-V) using its custom commands: READ/WRITE SRAM (0xD2/0xD3) and READ/WRITE I²C (0xD5/0xD4). Plain ISO15693 commands work fine (e.g., ReadSingleBlock / WriteSingleBlock). For example, reading config block 0x37 returns:     REQ: flags 0x22, CMD 0x20, UID=<8 bytes>, DATA=0x37 RSP: 00 08 DB CF 00 Now I’d like to send the NXP customs via rfalNfcvPollerTransceiveReq(), but I’m not getting a response (often RFAL_ERR_TIMEOUT). What I’m calling now For customs I call rfalNfcvPollerTransceiveReq(cmd, flags, param, uid, payload, payloadLen, rx, rxLen, &rcvLen) like this: flags: RFAL_NFCV_REQ_FLAG_DEFAULT (0x02, high data rate, no option bit) param: 0x04 (NXP manufacturer code) uid: 8-byte UID (addressed mode) payload and length per the NTAG 5 Boost datasheet (see below) rx: buffer big enough + checking rcvLen Example (READ SRAM, command 0xD2:

Split from this thread. i've had the same issue. Set the internal pull-up on Rx pin and pull-down on Tx pin.

Could you please suggest a PLC module that includes a signal scaling unit and an isolation circuit, equipped with a high-speed sampling ADC with up to 16-bit resolution? The module should also integrate a microcontroller featuring SPI, LAN (Ethernet), SD card storage, and an HDMI port.”

Hi everyone!  I designed the board shown in the attached picture. It’s built around an STM32H745 microcontroller, along with crystal oscillators, a DAC, an EEPROM, and an NE555 that generates a reset signal when a button is pressed long enough.  After assembling the board, I noticed that it draws an unusually high current (over 800 mA). The power supply goes into compliance and reduces the voltage, while the microcontroller itself becomes very hot to the touch. I noticed that the current rises with time to the compliance and over.To troubleshoot, I removed all external components (oscillators, DAC, EEPROM, transistors, and NE555), leaving only the microcontroller, but the excessive current consumption persists. I’ve checked carefully and I’m quite confident there are no shorts on the board.  When I connect via ST-Link using STM32CubeProgrammer, the tool successfully detects and identifies the MCU. However, within a few seconds, the connection drops because

Hello,I am designing a board with a STM32F446 connected to an IS42S16160H SDRAM through the FMC interface.Could you please provide ST’s official recommendations regarding the use of series resistors on FMC lines?Typical values (22–33 Ω)?Any ST guideline or application note available?Thanks,Rihem

The goal of my project is to turn on an LED on the recieving side through CAN. Both my reciever and transmitter have the transciever circuit. Both are Nucleo boards, TX: F303RE, RX: F446RE. The data i am sending through is 16-bit, but as long as my reciever is not in reset copnstantly (as in me holding the reset button when the program is running), the transmitted and recieved data is not correct, its far to short. The data is the same on TX and RX, but wrong. But when i hold reset on the reciever the data that comes through looks right.  I cant figure out what the problem is, i have measured the connections on the transcievers a million times, measured the RX, TX pin, CAN_H and L and always come back to the same issue.  I am programming the boards in Cube_IDE. The pictures below are of the boards and the signals i recieve. Please help. I dont see how this could be a hardware problem but maybe I missed something, i am still a begginer.    The reciever board is part

So the code should be modified as follows. Please help me confirm whether my understanding is incorrect or if there is indeed an error here? 

Hello everyone, the STM32F723IEK6 chip on my H755ZI-Q development board is damaged. If I replace it with a brand new MCU, how can I restore the program

Hi everyone, I am trying to reserve a block of RAM using a custom device tree overlay on my STM32MP157F-DK2 running Linux. Here's what I have done so far: This is my custom DTS overlay /dts-v1/; /plugin/; / { compatible = "st,stm32mp157f-dk2", "st,stm32mp157"; fragment@0 { target-path = "/reserved-memory"; __overlay__ { sensor_shm: sensor_shm@c8000000 { compatible = "shared-dma-pool"; reg = <0xc8000000 0x00040000>; /* 256KB */ no-map; status = "okay"; }; }; }; };   I compiled this to get custom-overlay.dtbo and placed it under /boot/overlays/. Then, I edited the /boot/mmc0_extlinux/stm32mp157f-dk2_extlinux.conf configuration file to include the overlay during boot by adding this line inside the appropriate boot label:   # Generic Distro Configuration file generated by OpenEmbedded menu title Select the boot mode MENU BACKGROUND /splash_portrait.bmp TIMEOUT 20 DEFAULT OpenSTLinux LABEL OpenSTLinux KERNEL /uImage FDTDIR / INITRD /st-image-resize-initrd

1.I have TouchGFX Designer 4.24.2 and STM32CubeMX running on Windows 11.  I downloaded the demos and examples via the file menu, also the latest TouchGFX Generator via CubeMX.  I am targetting a NUCLE0 STM32G071 with GFX01M2($AZ2) display, so I selected the demos for that board, and have tried several of them, giving each a project name and pressing Create.  In each case the progress bar goes to 88% then the program closes. If I restart TouchGFX Designer and try to open the project it has created in "TouchGFX Projects" folder, I get the error "Failed to open native freetype library".  If I manage to import the projects (individually) to STM32CubeIDE (1.17.0) they appear to be missing some header files and do not compile. The configured paths (in project properties) appear to be wrong.I also downloaded TouchGFX 4.22.0, thinking it may be a compatibility issue, but it did the same thing. 2.Is it feasible to run TouchGFX designer on Windows, then import the p

Hello,I am currently working with HSO for motor control and would like to clarify whether DPWM (Discontinuous PWM, 2-Phase PWM) is supported.In the Observer + PLL method, it seems possible to select discontinuous PWM by setting the modulation flag.However, I noticed that such an option does not appear to be available in HSO.Thank you in advance! 

I am using a NUCLEO-L053R8 board with an X-NUCLEO-NFC08A1 extension. I made modifications to the NFC08A1 to enable I2C communications and this works. I can read the A bank of registers and the values all make sense except for IO configuration register 1. It should have all 0s for the default value, but it always reads 0xFF. I can read, write, and read back IO configuration register 2 just fine. Even if I try to write all 0s to IO configuration register 1, it always reads back as 0xFF. I set up a scope to capture the i2c activity and it agrees with the firmware. Our firmware is custom, and we can successfully operate an NFC07A1 board. I am attaching a picture of the scope screen.

Hi there, Ive gone around in circles for hours on this. I'm just trying to read a frequency, around 150Hz typ. using the 32 bit timers, for now just TIM2, 4 channel but behaviour same on all channels. Using 16MHz clock the timer overflow happens around 4:40 mins, the read of the period and calc of frequency is fine, matches input signal, until the first overflow.After first overflow the period halves, frequency doubles, and stays like this for every subsequent overflow (confirmed by making a smaller ARR so overflows more frequency). I am trying to increment the high side of a 64bit counter-measurement value with the overflows and then populate the low side with the TIM2->CCR1. Below is my code, just one channel for brevity.As far as I can see it looks relatively textbook and it's just a simple task, it seems so odd that it just doubles the frequency reading on the first overflow but on no subsequent. Any help very gratefully received... // uint8_t TIM2_CH1_N

Is anyone able to identify this TSSOP EEPROM from the package marking "Z531"?  I'm trying to determine an orderable part number.  Thanks.

I've got a project that has the following files in the tree view:All is well if I clean and build, but if I open the .ioc and "Generate Code", the tree changes to:and the project then fails to build due to a duplicate system_stm32g0xx.c file.Why is this getting added and how do I stop it?I am using STM32CubeIDE V1.18.1.

Hey,I am trying to make a device which connect to an app using stm32wb15. Everything works properly, but I want to make it so that when the device becomes disconnected, i can use a button to broadcast BLE so that i can connect through an app again. I tried the existing ready functions. But I could not seem to make it visible as a Bluetooth device again (have to restart the device) Can someone point me to which functions i should call in the main.c to start broadcasting durign button press.
