My question here is this: Can the STM32G4x1 line access external flash memory (e.g., via QuadSPI)?My confusion is as follows: the following page:https://www.st.com/en/microcontrollers-microprocessors/stm32g4-series.htmlintroduces the STM32G4x1, G4x3, and G4x4 lines. In the table (at the center of the page), Quad-SPI (for accessing external flash memory) is listed in the left column as a common feature across all three of these lines.In addition, the slides athttps://www.stmicroelectronics.com.cn/content/ccc/resource/training/technical/product_training/group0/42/95/f2/b1/78/5c/49/55/STM32G4-Memory-QuadSPI_interface_QUADSPI/files/STM32G4-Memory-QuadSPI_interface_QUADSPI.pdf/_jcr_content/translations/en.STM32G4-Memory-QuadSPI_interface_QUADSPI.pdfindicate that "The Quad-SPI memory interface integrated inside STM32G4 microcontrollers provides a communication interface, allowing the microcontroller to communicate with external SPI and Quad-SPI memories". In addition, Ch 19 of the exhaustive

Posted on September 07, 2017 at 03:03HI,I'm currently test the STM32F429 Disco kit with some example on step by step.But I nerve that LCD always turn on, So Is there any way to turn off the lcd ? because I'm not ready to test the LCD.

Hello,For an end of study project, I use a STM32L073RZT6 MCU.I made an STM32 / Breadboard adapter. Like that : Now, I would like to program this MCU. For this, I was given a ST-LINK / V2. I used the MCU and ST LINK datasheet to make the following connections:I then used the ST LINK software to try to connect, impossible!I tried several things, with the BOOT, Reset .. But nothing helps.I checked the pins, but absolutely nothing.Did I forget something to keep it from working?

Im can not set SNSINC-bits from MACSSIR Sub-second Increment Register. Other Bits like SSINC I can set without problem ! (STM32H745XIH6U Discovery Kit ). Look like a Bug ?

Hi all,I am using the  ST25R3916 Discovery GUI to communicate with an NFC03 board in CE mode and so far I have been using the ISO14443A Tab and Debug tab to exercise the functionality. I have a few questions regarding the GUIIs there an updated or more detailed manual/documentation on the GUI -- the hosted version doesn't contain information regarding the ISO-DEP tab.What is the difference sending out a command via the ISO-DEP tab vs the Debug Tab.Can somebody point me to the firmware section that processes/interfaces with the GUI across the different tabs, fields and buttons?Is it possible to rebuild the GUI with some additional functions or buttons? Some additional functions that I would like to have is to be able to send a large chunk of data which then will be parsed into multiple frames and get sent across and likewise receive multiple frames and reparse them back into its original form.Would appreciate a PM if that would be easier for communication, thanks!!

Hi everyone,I am student who is new to STM32. I am trying to understand how to program the MCU and noticed GPIO_InitTypeDef data type. I went into the reference manual but did not find anything about it. Is there a document including all the functions a user can apply to the STM32 (and hopefully find information on GPIO_InitTypeDef) ? Thank you in advance.

According to product page X-NUCLEO-IHM03A, this motor driver voltage range should be between 10.5 V to 85 V. But I got a sample I do see Vin max printed as '50V'. Can someone from the nucleo explain which max voltage spec I should choose?

Hi...Here the problem so far: I have a well running debug configuration, everything runs fine on target. It´s programmed into memory (using internal and external flash via qspi) and now it comes to play around with the connected (custom-) hardware. Testing different input-settings, moving around jumpers and dip-switches, connecting different motors with (of course...) different settings, changeable via my software and so on.Of course i need to stop debugging, switch off the target, change my (hardware-) settings and restart debugging.If you have to do this for around 100 times per day, it can be very annoying, that EVERY time, i press the "debug"-button, the cube programmer starts and is flashing the same code again and again. I changed to CubeIDE recently and i really miss that feature, i´ve had in Visual Studio with VisualGDB on top: To flash the board only, if rebuilt since last time.Now the question: Am i just to stupid, to find it or is there even a way to set this up ??/Charly

Hi, I'm currently porting OpenAMP virtio to Arduino platform: https://github.com/stm32duino/Arduino_Core_STM32/pull/766I would like to share one thing about the OpenAMP examples in CubeMP1.Here is the implementation of MAILBOX_Poll:int MAILBOX_Poll(struct virtio_device *vdev) { /* If we got an interrupt, ask for the corresponding virtqueue processing */ int ret = -1;   /* USER CODE BEGIN PRE_MAILBOX_POLL */   /* USER CODE END PRE_MAILBOX_POLL */   if (msg_received_ch1 == RX_BUF_FREE) {   /* USER CODE BEGIN MSG_CHANNEL1 */   /* USER CODE END MSG_CHANNEL1 */   OPENAMP_log_dbg("Running virt0 (ch_1 buf free)\r\n"); rproc_virtio_notified(vdev, VRING0_ID); msg_received_ch1 = RX_NO_MSG; ret = 0; }   if (msg_received_ch2 == RX_NEW_MSG) {   /* USER CODE BEGIN MSG_CHANNEL2 */   /* USER CODE END MSG_CHANNEL2 */   OPENAMP_log_dbg("Running virt1 (ch_2 new msg)\r\n"); rproc_virtio_notified(vdev, VRING1_ID); msg_received_ch2 = RX_NO_

I am doing some basic bluetooth development with the WB55 Nucleo Board using the STMWB Workshop videos as a guideline. Following this, I was able to reproduce the example project that blinks the LED and reads the button state of the board with the ST BLE App. I am also testing with a bluetooth app that generically connects to a device, retrieves the services/characteristics, and interacts with them by sending/receiving bytes. On workshop video 4, the tutorial diverged from the Cube MX version I was using (5.6) when enabling a Custom Template. Using Cube MX 5.6 generates a number of additional fields to configure the custom services/characteristics (not present in the videos), which seemed to make it easier to set everything up. I simply want to create characteristics to read/write arrays of bytes, but I can't seem to figure out the correct settings in Cube MX to get this to work. To make things simple, I started by trying to create a single service and characteristic to write a byte of

The process is as follows:config the variables node ,choose the axf executable filespitch on Expand Variable Listwaiting for the file parsing,and then the software breakdown

I am trying to get the stm32L010 lpuart TX out of PA14. The datasheet says this is AF6. However, despite uart interrupts etc all working (so I assume the lpuart block is configured ok) I can get nothing on PA14. This isn't helped by the fact that PA14 is also SWCLK so debug is not possible.However, PA14 can be used for GPIO. So, for IO initialisation I have done the following: GPIO_InitStruct.Pin = LL_GPIO_PIN_14; // GPIO_InitStruct.Mode = LL_GPIO_MODE_ALTERNATE; GPIO_InitStruct.Mode = LL_GPIO_MODE_OUTPUT; GPIO_InitStruct.Speed = LL_GPIO_SPEED_FREQ_VERY_HIGH; GPIO_InitStruct.OutputType = LL_GPIO_OUTPUT_PUSHPULL; GPIO_InitStruct.Pull = LL_GPIO_PULL_NO; // GPIO_InitStruct.Alternate = LL_GPIO_AF_6; LL_GPIO_Init(GPIOA, &GPIO_InitStruct); LL_GPIO_SetOutputPin(GPIOA, LL_GPIO_PIN_14);and within LPUART1_IRQHandler() I have added: // Transmit register empty if(LL_LPUART_IsActiveFlag_TXE(LPUART1)) { LL_GPIO_TogglePin(GPIOA, LL_GPIO_PIN_14); ........ etc }I can then see PA14 toggling

IN the function USBD_HID_setup for a class requese I added a case for send report. case HID_REQ_SET_REPORT: Debug::Instance()->printf(Debug::ALLWAYS, (char *) "Set report %X\n", req->wValue); Debug::Instance()->printf(Debug::ALLWAYS, (char *) "Received: "); for (int ii = 0; ii < req->wLength; ii++) Debug::Instance()->printf(Debug::ALLWAYS, (char *) "%02X ", CtlEP0OutData[ii]); Debug::Instance()->printf(Debug::ALLWAYS, (char *) "\n"); Report::Instance()->ProcessReport(CtlEP0OutData); USBD_CtlPrepareRx(pdev, CtlEP0OutData, sizeof(CtlEP0OutData)); return USBD_OK; break;The first time I get here the buffer is empty, the second time is shows data from 1st transfer. Bus analysis says the data is being transferred as exepected. Moving USBD_CtlPrepareRx before the print (even with a delay) does not change the behavior.Thanks for looking,Rob

Thank you!

Hello when I enter NVIC settings for timer interrupt, there are different interrupts for TIM1. Such as: TIM1 break interrupt, TIM1 update interrupt, TIM1 trigger and commutation interrupts and TIM1 capture and compare interrupt. What is the difference between these interrupts? I want to use timer 1 as global timer interrupt but there is no option for that in CubeMX. Which interrupt I can use for this purpose?

Hi,We are currently developing on the STM32MP1. Our goal now is to be able to debug the core at the different running stages : TF-A, Optee, U-boot and kernel. We are using the DK2 with a ST-link and openOCD.When using your Setup.gdb we experience some issue during the debug session : We can't use the step instruction but we can use the stepi instruction. When we use the step instruction we have the following error on openOCD :Error: Timeout waiting for cortex_a_exec_opcode Error: Timeout waiting for InstrCompl=1 Error: Timeout waiting for dpm prepare Error: Timeout waiting for cortex_a_exec_opcode Error: can't add breakpoint: unknown reason Warn : negative acknowledgment, but no packet pending Warn : negative acknowledgment, but no packet pendingThe exact same error message is found when loading u-boot symbol after gdb is connected to openOCD.The software breakpoint doesn't work, only the hardware breakpoints break the core.We also have some questions regarding this debug script :Wha

I'm using VS 2019 with visualgdb extension for stm32f303vc device. I have a class TlteCom with array of pointers to members of the c++ 17 class. Here it is.class TlteCom { public: volatile uint16_t number=0; volatile uint16_t paramNumber=0; volatile char param1[20]; volatile char param2[20]; volatile char param3[8];   constexpr static uint8_t paramCount = 3; volatile char *const paramlist[paramCount] = {(volatile char *)param1, (volatile char *)param2, (volatile char*)param3}; volatile uint16_t paramlength[paramCount] = { 0, 0, 0 }; };I create the object of the class as global variable as follows: TlteCom com;I don't understand why com.paramlist members are all zero. if I create object of the TlteCom class on stack in main() function everything is ok: com.paramlist has right values of param1, param2, param3 addresses. So, what is the right initialization of pramlist array?Help, please!And thank u in advance!!!

Hi,I want to use an image but it takes up a lot of space in FLASH memory when I add it.Example:Image size ------ (no image) ---- 7.55 KB -------- 2.38 KB (same picture but compressed)FLASH (free) ---- 811.97KB ----- 385.55 KB ----- 385.55 KB(Instead of) -------------------------- 804.42 KB ----- 809.59 KBI don't understand why...Do you have the same problem?Best Regards

I am setting up a custom board for the STM32F743 and only the first 18% or so of the screen is being displayed. The rest is garbage.. If I write directly to the framebuffer, the LTDC does write out to the display, so I know my SDRAM and LTDC are configured and functioning properly. I suspect a TouchGFX configuration issue and am wondering if the AT for the STM32H743-EVAL v3.0.0 will be available soon?

Hi, where can I find schematic and footprint for STM32H753 (or STM32H7 xx family) for Altium? In the STM32H7 and STM32H753 page I cant find nothing.Best regardsGMG

I'm running out of timers on the STM32G431RB that I am designing for, and am inclined to try to use TIM_15, 16, and/or 17 for upcounting (only! not up/down quadrature counting) encoders, for rotary encoders on shafts that only spin one direction. Is this possible? I'm finding quite a lack of information on this type of application for these timers in both the STM32G4 Datasheet as well as the 2000+ supplemental Reference Manual.

The ADC (ADC3 if that's relevant) provides for triggering by way of the TIM6 TRGO event. I have the ADC configured to convert with "ExternalTrigConv" pointing to ADC_EXTERNAL_TRIG_T6_TRGO, and the update event's rising edge. In no case am I able to get the thing to trigger though, not off of TIM6, only by software conversion start. I'm sure TIM6 is firing because when I intercept its ISR it's running on time, it's just not triggering the ADC.The errata for the 32F4xx suggests that one has to enable the DAC RCC clock domain for it to work. This doesn't help on the H7 (and it's not mentioned in the H7 errata). Has anyone managed to use TIM6 to trigger conversions of the ADC? I can start the s/w conversion in a roundabout way (roundabout because of the HAL locks if I do stuff in ISRs) after TIM6 fires its ISR but I'd rather not couple things so closely. TIM6 when it's mentioned in the docs is always in relation to the DAC and not the ADC so I wonder if the connection just doesn't exist on

I'm not sure how many H7xx applications deploy without EEPROMs. Everything I've touched in the last 5 years in the F3xx and H7xx line needed an EEPROM for the usual customer side configuration persistence requirement. My customers prefer to take the BOM hit for an external EEPROM like the 24C256 or even the weird PCA9500 multiuse I2C device (4 byte pages!) rather than setting things up to possibly exhaust flash words should firmware lose its mind and exhaust the flash area in seconds when used as an EEPROM substitute.I'm sort of afraid to ask for new things that may tend to break old things but it'd be cool if ST would add a small true EEPROM to the device, maybe not the value line but for the more premium parts with more oomph. 256 bytes should be enough and it's a product ST already makes so....
