I try implement 1424x280 DSI panel and it work, but transition on single buffer have trouble.I start with simple fadeout and attached video show result. Try off DCACHE ICACHE DMA2D GPU2D, no big difference. Exist example or recomm for video mode with TE signal memory single buffer manage ? @GaetanGodart  ... seems i cant upload video  https://drive.google.com/file/d/1l9psb7h2DsEAAxUi8_kvEnL9ac-wNu1_/view?usp=sharingTGFX 4.23.2

I'm just starting to learn about MCUs and am reviewing the datasheet for the STM8S003F3. In the pin description table, I came across some symbols that I'm not quite sure about, such as bold X with underline (X), regular X (X), and dash (-). What do these symbols mean? 

Hello everyone,I’m working on a project in STM32CubeIDE with C, and I’d like to add a C++ library. I’ve read that it’s possible to mix C and C++ using different compilers, but in my project settings (C/C++ Build > Settings > Paths and Symbols), I only see the GNU C compiler (arm-none-eabi-gcc).How can I add the C++ compiler (arm-none-eabi-g++) in STM32CubeIDE?Do I need to change any other settings to properly handle mixed C and C++ code in the project?Thank you for your help!

Hi All, I was testing my new STM32H746XIH6 board and met the post below by @GSpre.1 during a search about SDRAM  performance. GSpre.1 - Performance characteristics of SDRAM on STM32F7508-DISCO board I don't have a lot of time to read MPU documentation, maybe someone has an idea about the code piece below that @GSpre.1  adviced.  I did not perform a precise measurement but used Systick for both internal and external (32-bit SDRAM) memory array manipulation time for the same data length. (I-Cache and D-Cache are both enabled as expected.)Internal memory test:  12ms External memory test: 47ms without the code below  External memory test: 13ms.with the code below * What exactly the code below does ? * Am I compromising from anything for speed ?  There are a lot of job to do during board bring-up I have no time to read a lot of documentation. I will be appreciated if

Hi,I'm using STM32WB5MMG and placed it in the top left corner of the PCB as recommended. The component assembly is top side only so I can't place the decoupling capacitors for VDD, VDDA, VREF+. Also, the schematic of Sparkfun's MicroMod Processor using STM32WB5MMG has a Note: "Decoupling capacitors are integrated onboard the module." So, I'm confused now. However, I've enough space to add 4.7uF Capacitor which is recommended to eliminate ripple on power supply.So, is it okay to completely drop these 100nF decoupling capacitors from the schematic itself which are shown in MB1292 (STM32WB5MMG Discovery Kit)? Will it make a difference for being there or not in this module's case?Thanks & Regards,Sumit

Hi allim using the STM32L4R9AI evaluation board ,with IS66WVH8M8BLL HyperRam memomry.with the help of AN5050 i try to communicate with this device in memomry map modeand also toke for reference the memory map mode in STM32CubeH7 package (https://github.com/STMicroelectronics/STM32CubeH7/tree/master/Projects/STM32H735G-DK/Examples/OSPI/OSPI_HyperRAM_MemoryMapped)) i notice that during my memoey allocation operation the MCU not putting the data in the desire location and it not working as expected.the behavior that i saw in that the data was written into the device but not in order.Is it due to this device in PSRAM ?i saw at ERRATA es0393-stm32l4rxxx @ 2.8.22 that OSPI not supported in PSRAM ,but i am working with the HyperBus and also in the device DS also noted that itusing a self-refresh DRAM array organized ( so it is not regular PSRAM )please see below my code that i'm using.the FREQ is 120 MHz..please find attached my code ,INIT, HperRam Deviceappritiate an

Hi,this is my MCU code: STM32H563VGT6. I'm working to a porting from Texas to ST.I need to efficently use the two Rx FIFO (3 messages depth) of the FDCAN module. In Texas I had 32 mailbox divided into transmission and reception.Each FIFO has four buffer.I need to accept all messages I receive.I would like to find a way to fill FIFO 0 and then move to FIFO 1.The only solution I found is to create two range filter: one for the first half part of IDs space assigned to FIFO 0, the second for the rest of IDs space assigned to FIFO 1.In this way I'm going to overload FIFO 0 or FIFO 1, depending on the IDs that I receive. There is a way to maximize the use of two receive FIFO ? Thank you.Regards.

I am making a board using your WLC38RX chip.I had a problem during the experiment. When I applied a load and then disconnected it, the board rebooted.So I found a solution. When I updated the Rx f/w, the reboot did not occur.In order to find the parameter that affected it, I manually changed the config settings from the initial state without f/w update to the same as after the f/w update, but the board still rebooted.I wonder why there is a difference when the Rx registers config settings are the same.Is there an invisible setting value?The f/w used is STEVAL-WLC38RX_config_1F46_EPP.memh.

Hello, i need help with na stm32l031k6, I want to just start the processor and read it with an st-link v2, I have connected BOOT0 to GND(i haven't added a 10k resistor, but that shouldn't be the problem ), NRST with pull-up 1k to VDD, VDDA and VDD are connected together. From what I read online I can pass without the external crystal because there is an internal one. So when I connect the VDD to 3v3 on the st-link, the GND to the st-link GND, SWCLK to PA14, SWDIO to PA13 and the chip isn't recognized. I have ruled out an faulty st link because it recognizes a blue pill f103 board. Please tell me if I am forgetting something

I am starting some test with this modulehttps://it.aliexpress.com/item/1005002482177244.htmlwith 7” lcdI have found only one example that run but with TouchgfxI have got the same ioc from this example to generate a new code and insert the functions to switch on lcd but still no resultI would like to use the normal functionsBSP_LCD_Init() ;BSP_LCD_DisplayStringAt(10, 80, buf, LEFT_MODE);BSP_LCD_DrawBitmap(0, 0, (uint8_t *)(&BackGround0));   

I can connect in STM32CubeProgrammer my BluePill but can't do that in STM32CubeIDE. I fixed that my ST-LINK's pins were reverse in it. The problem I get is,Error in initializing ST-LINK device.Reason: ST-LINK: Could not verify ST device! Abort connection.I have downloaded STSW-LINK009 already. Can you help me?

Hello Guys,I am searching for a MCU to drive dual LCD screens. Although I see some MCU (eg, STM32U5G9ZJTXQ) providing both DSI and RGB mode interfaces without pinout collision, I didn't see any description about whether the LTDC can output 2 different images to the different interfaces respectively. Can I get your experiences sharing?Thanks in advance,SRONY

Hello,We have a project that uses STM32WB55 as the main controller.This project has certain requirements for power consumption and wants to enter sleep mode through stop2 mode.But I tested the power consumption current of stop2 mode on the STM32WB55 DK board (Nucleo-WB55) and it was 107uA.  We have configured RTC and external interrupts to wake up stop2 mode, and we want its power consumption current in stop2 mode to be less than 5uA.May I ask if the power consumption current can reach 5uA when enabling RTC Alarm A and external interrupt to enter stop2 mode?I used the routine on the stm32wb55 official website to test the stop2 mode: STM32Cube_FW_WB_V1.22.0\Projects\P-NUCLEO-WB55.Nucleo\Examples_LL\PWR\PWR_EnterStopModeI added serial port printing and configuration before entering stop2 mode to this routine.Now I have configured the MSI clock to 100Khz.void EnterStop2Mode(void) { LL_GPIO_InitTypeDef gpio_initstruct = {LL_GPIO_PIN_ALL, LL_GPIO_MODE_ANALOG, LL_GPIO_SPEED

I am trying to persuade an stm32F412 to provide Periodic PC sample packets.Reference manual RM0402 implies it is doable (Configure DWT as a PC sampler)The "Cortex-M4 Technical Reference Manual r0p0" says "You can configure the DWT to generate PC samples at defined intervals" and DWT registers are described in the ARMv7M Architecture Reference ManualThat reference manual contains what I thought were reasonable instructions.I can see the CYCCNT register changing value as expected.I have confirmed that ITM and DWT registers can be written to. I'm obviously missing something!The below code does generate ITM packets over the SWO interface of my stlink v2-mini e, picked up via openocd, so I believe that the serial and clock speeds are set correctly.   DBGMCU->CR |= DBGMCU_CR_TRACE_IOEN; CoreDebug->DEMCR |= CoreDebug_DEMCR_TRCENA_Msk; DWT->CYCCNT = 0; ITM->LAR = 0xC5ACCE55; // unlock the ITM registers ITM->TCR |= ITM_TCR_ITMENA_Msk; //

Hello everyone,I am developing a custom PCB and am having a problem while trying to flash the chip.Before delving further, I need to say that I have made a mistake with routing the JTAG traces to 10pin JTAG connector and may have burnt the chip. I tried to circumvent this by soldering a new chip and using external wires as made a new connector for JTAG 20 to 10pin adapter (https://www.adafruit.com/product/2094) which then connects to ST-LINK/V2:After this I would get TDI ERROR message. I tried every possible type of connection available on STM32 ST-LINK Utility and STM32CubeProgrammer. I only maybe haven't tried to lower down the frequency.I checked the connections made to the chip and everything seemed fine. Every power pin gets correct voltage and there are no short circuits. The power comes through 2 LDOs: 1 is 3.3V and the other is 5V and the power input to the board is 12.5V and around 70mA. The boot pin 1 is connected to ground.I do not know what to try n

Hi,I am using STM32G0B1RE with the ISM330IS sensor, I just want to understand the procedure of loading a program into the ISM330IS ISPU memory, after compiling my algorithm I have the SREC binary format,  what should I do next ? from what I understand I need to let the host device to load the program into the ISPU, so I am thinking of copying the SREC data into a buffer then loading the program to the ISPU program RAM, so on every power cycle the host needs to load the ISPU program before starting fetching data is that correct ?

Simple question:If i'm right the serial number returned by cat /sys/firmware/devicetree/base/serial-number is the UID from BSEC. Where is the code responsible for setting this value? I've seen the function get_board_serial in u-boot but it doesnt seem to be implement for the stm32mp1 board.

Hello everyone,I am currently experimenting with X-Cube-AI with a NUCLEO-G474 (because i get some weird errors with NUCLEO-N6 [N6 Post] ). I am trying to run a very simple network with the validation application. I have some Questions which i have not been able to answer myself regarding X-Cube-AI.I first tried to print something to my pc console. I used UART with the function HAL_UART_transmit. This works fine.Then i want to do the same with the X-CUBE-AI package in use. The first thing i see is that syscalls.c is removed from the core folder and moved into X-Cube-AI/app. In  app_x-cube-ai.c in MX_X_CUBE_AI_Process() ->aiValidationProcess() i found the function LC_PRINT which also uses HAL_UART_transmit. But i cant see nothing in my terminal.I am not sure what i did wrong. Can someone help with this problem?

Hello, I plan to make a 333V Battery using AEK-MCU-C4MLIT1 as the master, AEKSCOM-ISOSPIA as the translator and AEK-POW-BMS69EN as the slave BMS Boards.  So far, I have been using the Example "SPC58EC—AEK_POW_BMS63EN_SOC_Estimation_Single application for discovery" to connect the Master to a single slave and receive cell voltages and temperatures. That has worked well.  Now, the next step of the project is to connect the slaves in a daisy chain and get individual data. Since the battery modules are supposed to be connected in series, I can't connect the slave boards using the USB connection. Thus, I have only connected the ISOH & ISOL lines.  As per the support document, I can't directly use the same example when I have multiple slaves. I should use the following examples: "SPC58EC - AEK_POW_BMSWTX_SOC_Est_SingleAccess_CHAIN application for discovery" However, I am not able to get cell data from even a single slave if I use this example, even when I change the connec
