Hello!Q1: We wonder if it is possible for evaluation to change the resolution from 800x480 to something like 640x480 (or even 320 x 240) on the f469I-DISC0 by changing parameters.The screen should then show black 80 pixel to the left and 80 pixels to the right, the active screen should be positioned in the middle (like on a standard monitor).Reasons to do so:- target application does just need lower resolution- remarkable memory saving (e.g. using internal SRAM)- saving 20% (640/800) bus bandwidth can have an impact while evaluating for a 640 x 480 solution. With 800 x 480 we already have issues with DMA2D (we need to set the "DeadTime" to a value of 230 to avoid "bucking").- higher framerates for nice animationsWe played already with values for horizontal front- and back porches (""nt35510.h"), in the hope, this produces the black bars on the left and right side but with no positive effects, there are no black bars at all... Q2: We were able to change the frequency of the LTCD to

           Hallo everyone,I tried to export the measured data of my project on a WeAct-3.0 STM32H723 board as an USB_OTG_HS stream to a Virtual COM Port on my Windows desktop. Unfortunately, I fail to get this operational, despite many trial and error attempts. Finally I reduced the challenge to just writing a test-string to USB, but even this minimal task doesn't even invokes a port in the Windows Device Manager.Still being a beginner, I work with STM32CubeIDE, version 1.16. I created a new project, configured the HSE with a 25MHz crystal, configured the CPU clock @ 250MHz, and the USB clock @ 48MHz via HSI48. I configured an uint8_t array 'text' with a string constant assigned to it. Finally in the main 'while()' loop, I invoke the statements:Return_CDC_Transmit = CDC_Transmit_HS(Txt, sizeof(Txt));HAL_Delay(1000);Count++;When I run this project with the Debugger, I see the value of 'Return_CDC_Transmit' become 1 (Busy) and 'Count' inc

When i try to set ADC sequencer to not fully configurable, ADC shows ADC_Regular_conversion_Mode error after migration of the .ioc file from previous version of CubeMx. In the previous version of CubeMx everything worked well. Help please!

Hello, I am working on a project using the STM32WLE5JC module and STM32CubeIDE for development, with firmware packge v.1.3.0.We are currently running EMC tests at a test facility, and they have requested for the ability for the device to send data every 500ms (to The Things Network, TTN). Is  this doable? What configuration will be needed to accomplish such a fast transmission rate?Thanks

Version: MCSDK v6.3.0, CubeMX v6.9.2, STM32 FW V1.5.2 (using HAL)Tool: Firmware generated by MCWB, no modificationDetails: Pressing button SW1 on EVLSPIN32G4-ACT is supposed to start the motor, but instead makes the motor buzz for a second, then stop. I successfully ramped the motor with B-G431B-ESC1 dev kit and I'm using the same `mc_parameters.c` file (14 pole motor, RS=0.11836, LS=0.04).  I also tried the same main.c code on the EVLSPIN32G4-ACT as the B-G431B-ESC1 main loop.Expected Behavior: motor should spin as it does in this demo video https://www.youtube.com/watch?v=DIMeHnKfJZ8How to reproduce: Use EVLSPIN32G4-ACT, generate default project from MCSDK, press SW1 to try and run motor.Can anyone tell me what variables I might look at to troubleshoot this issue?  Or possibly some more example code to try? Thank you

I am currently implementing a series of  vl53l4cd sensors into a project. These work really well and I am able to address these individually on one shared i2c line. These sensors are working perfectly fine on this shared line when measured independently but when an object is blocking both sensors, the readings speed up and the readings of both sensors becomes much less accurate and noisy. Is there a specific approach to reading sensor data from both sensors simultaneously? As a test I did move one of these sensors onto another i2c line, and the issue continued. I originally thought it was congestion on the i2c line but it clearly isn't and may be the way I am getting the distance data from both sensors. I am using the Arduino library - https://github.com/stm32duino/VL53L4CD/ I have attached a video which should hopefully show what I am seeing. The yellow line is one sensor and blue is the other.  Thanks  

I'm having a problem where the linked complains to me with undefined reference to `HAL_TIM_PWM_Init' erros. The objects that it complains are not defined are HAL TIM based ones such as HAL_TIM_PWM_Init or HAL_TIM_IRQHandler. There is a source file with these functions defined that is compiled "stm32f7xx_hal_tim.c" but for some reason the linker still complains.Here is some source code (the last line gives me the error):#include <string.h> #include "stm32f7xx_hal.h" #include "stm32f7xx_hal_tim.h" #include "ws2812b.h"   extern WS2812_Struct ws2812b;   // Define source arrays for my DMAs uint32_t WS2812_IO_High[] = { WS2812B_PINS }; uint32_t WS2812_IO_Low[] = {WS2812B_PINS << 16};   // WS2812 framebuffer - buffer for 2 LEDs - two times 24 bits uint16_t ws2812bDmaBitBuffer[24 * 2];   // Gamma correction table const uint8_t gammaTable[] = { 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 1, 1, 1, 1, 1, 1, 1, 1, 1,

Hi, Can you confirm if the X-NUCLEO-GFX01M2 has a color display or monochrome display? 

Hi everyone,   I start to question myself and this whole programming thing....   I'm using a STM32F3-Discovery Board and generated a code with STM32CubeMX in default mode. I changed absolutely nothing before code generation.   In main.c I added the following code to the default one:   #include "math.h" #define PI 3.141 uint32_t sine_val[100];   void calcsin(void){         for (int i=0; i<100; i++) {         sine_val[i] = ((sin(i*2*PI/100) + 1)*(4096/2));        } }   That's all. So nothing special at all. The thing is, everything is fine but whenever I try to call calcsin() in the int main function I get the following error:   Error in final launch sequence:   Failed to execute MI command: load E:\\STM32\\Workspace\\090924\\Default\\Debug\\Default.elf    Error message from debugger back end: Error finishing flash operation   Also the STM32CubeIDE opens another erro

HI team,               I am using STM32F769 board , do we have sample code or example for USB RNDIS application for F7 series. 

Hello ST Micro community,I'm working with a NUCLEO-F746ZG board and have noticed some interesting behavior regarding memory usage. I'd like to seek your advice on the following:The VTOR (Vector Table Offset Register) is currently set to 0x00200000.The contents flashed to 0x08000000 (Flash memory) are mirrored at 0x00200000 (RAM).I haven't seen a linker script that explicitly uses the 0x00200000 address range for the uploaded code.Given this situation, I have two main questions:a) What could be the reason for VTOR being set to 0x00200000? Is this a default behavior for this board or a specific configuration?b) Using the 0x00200000 address range (RAM) could potentially be more efficient for code execution. How can I modify my project to take advantage of this? Specifically, what changes would I need to make to the linker script to utilize this memory address?Any insights or guidance on how to optimize my setup would be greatly appreciated. Thank you in advance for your help!Here's the co

HI,      I am trying to interface the USB device with a customized STM32H563ZIT6 controller board. I followed the example steps from the STM Community, but the USB port is not detected.

I have created a configuration for use of an external tool (PCLint) and successfully ran the tool in my STM IDE. I exported that configuration and got the .launch file, but now other developers on my team want to run the same external tool configuration and we cannot figure out how to do this. All the info is in the exported file, we're just missing how to get that info into the IDE to avoid having to manually copy and paste all of the fields.

Please let me know if there are any hardware or sofware specifics for connecting TCXO to the STM32G474 series? What should pay special attention to?I use FT2MN at 40 MHz. Its output was connected through a 10 pF capacitor and a 220 Ohm resistor, in series, to PF0 RCC_OSC_IN.I'm running CubeIDE 1.16.0.Unfortunately this doesn't work, I'll use a primitive for testing:  while (1) { HAL_GPIO_TogglePin(GPIOC, LED_G_Pin); HAL_Delay(100); /* USER CODE END WHILE */ /* USER CODE BEGIN 3 */ }  When power is supplied, the LED_G lights up constantly. After pressing the reset button, it turns off and does not turn on again. If I turn the power off and on again, everything repeats itself. When I change the configuration to the built-in RC generator. The LED_G flashes as specified by the program, the reset button works correctly. I tried to see what happens at the input PF0 with my DSO2D15 oscilloscope, the declared band is 150 MHz, with the original probe in the 1:10

Hello,I am trying to use RF with iOS and Android to write into the memory of the ST25DV04KC. Reading is not a problem, but the difficulty is the protection. There are two areas: Area 1 is only used for the NDEF message and is locked with Password 1. Area 2 is the data area, which is also protected with Password 1. So, reading does not require a password, but writing with RF into the area does.I studied the datasheet, and it looks very confusing. I can't figure out how to handle writing multiple blocks into an area that is password-protected.Here is more information: I initially used the Req_Flag, which is 0x62 or 0x22, with the ID of the chip. The command for multiple block writes is 0x24, and the starting block is 0x0A (which is Block 11). To write two blocks, I use 0x01 (because the number of blocks is -1). I also saw that the maximum number of blocks is 4, so the maximum number of blocks to write in the data area is 0x03. When I issue these commands with the NFC Tag app, it says tha

I would like to sample the entire GPIOA Port using the DMA and TIM16. TIM16 triggers the DMA which in turn is supposed to copy the content of the IDR register of GPIO onto an array. This works fine if I use the CNT register of TIM16 as CPAR. When I switch to the IDR register of GPIOA, the transfer error flag is set.I found a post stating that the GPIO on the G0 series is on a private bus and therefore not available for the DMA. Is this the case for the C0 series too? If so, is there any other way to copy the content of the IDR register in a fixed interval except for doing it in a timer interrupt routine?Many thanks in advance for any replies!

您好我们使用NFC08A1开发板做NFC识别时，功率无法达到介绍中的1.7W。开始以为是VDD_RF的电压偏低，然后控制寄存器2C的rege将VDD_RF的电压设置为5.1V，使用B区域寄存器2C和万用表读取都没达到5.1V，测量到的最高电压只有4.9V。而且运行直接命令开场后电压降为4.6V。开发板的最高电流只有100mA。排查过供电电源没有功率受限的问题。想问下如何提高功率，期待获取到贵公司的指导。 Hello.When we use the NFC08A1 development board for NFC identification, the power cannot reach the 1.7W in the introduction.At first, it was thought that the voltage of VDD_RF was low, and then the rege of the control register 2C set the voltage of VDD_RF to 5.1V, but the reading of the B-zone register 2C and multimeter did not reach 5.1V, and the highest voltage measured was only 4.9V. And the voltage drops to 4.6V after running the direct command. The maximum current of the development board is only 100mA. Checked that the power supply is not limited.I would like to ask how to improve the power and look forward to getting your guidance.

Hi, I have a custom board based on a STM32MP153 and I'm trying to reduce CPU (MPU) max frequency... Now it's running at 650Mhz, which is the default configuration. looking at the Wiki : https://wiki.st.com/stm32mpu/wiki/How_to_change_the_CPU_frequency#CPU_frequency_configuration_2 in the configuration side, it seems to me that changing PLL1 clock is enough (thanks to TF-A algorithm).But nothing is changing... Running the command cat /sys/devices/system/cpu/cpufreq/policy0/cpuinfo_cur_freq I still see 650Mhz and u-boot prints always 650Mhz:   U-Boot 2021.10-stm32mp-r1-dirty (Oct 04 2021 - 15:09:26 +0000) CPU: STM32MP153CAC Rev.Z Model: STMicroelectronics custom STM32CubeMX board - openstlinux-5.15-yocto-kirkstone-mp1-v22.06.15 Board: stm32mp1 in trusted mode (st,stm32mp157c-es-dcc-proto-b-mx) DRAM: 1 GiB Clocks: - MPU : 650 MHz - MCU : 165 MHz - AXI : 201.333 MHz - PER : 0 MHz - DDR : 302 MHz The other peripherals (e.g. AXI or DDR) seems to

Hello,  I currently have SPC560P chip which I am able to program using SPC5 Studio and Debug using SPC5-UDESTK. The compiler that I have currently selected is "FreeGCC with VLE Support" by going to the Application Configuration -> SPC560Pxx Platform Component RLA -> Build Settings.I see the other options in the dropdown of Compiler Variant such as Hightech and GreenHills. The issue that I am currently facing is that I am modifying only a part of the existing code and I need to use another compiler when merging with the old code. So I was wondering if I can change the compiler to "mwcceppc" from "FreeGCC with VLE Support"  in SPC5 Studio ? If Yes, how ? I have added the path to "mwcceppc" in the SPC5 Studio -> Windows -> Preferences -> C/C++ -> Build -> Environment. And also the same in Project Properties. But I believe the settings in Configuration.xml will override these settings ?Let me know if this is a possibility or not.
