We are looking for a sensor that can identify tilt angle with respect to gravity. I have been looking around at 3-axis accelerometers but cannot be sure if these will work as a tilt angle sensor. Please advise.NOTE: This question and answer originated from a customer support case which was handled by us. We regularly review support cases and add any helpful ones here for all to benefit from.

Hello all, I tried to integrate touchGFX to ​STM32CubeMX and I'm using keil to complie all the files. The complication is successful yet mountains of errors occurs during linking ! All errors are of the same type like this: Error: L6654E: Rejected Local Symbol .x refered to from non group member x.o (.iar.stackusage) Please help! I think I'm almost there!

STM32L041F6 - I configured RTC for wakeup every second from Stop mode. It works ok, but after external reset (NRST pin) it not working. Program run in main while() only once, to line:HAL_PWR_EnterSTOPMode(PWR_LOWPOWERREGULATOR_ON, PWR_STOPENTRY_WFI);After switch power supply OFF / ON it is working again correctly with 1Hz wake up and stop mode. I am affraid, if cpu will be reset from some reason, application will be "freezed".I readed similar bugs about external wakeup, I tried more solutions, but it is still same. What is needed for fix "RTC wakeup bug"? What I forgot to do? Thanks

HiI would like to know if there is any IBIS models available for this devices?RegardsLin Biao

I read the 4.10.0 User Manual on CanvasWidgetRenderer. I was unsure what it means by "CanvasWidget will not allocate memory dynamically, but will use memory from the buffer kept in CanvasWidget -Renderer."I see the commented line in main.cpp://static uint8_t canvasBuffer[CANVAS_BUFFER_SIZE]; //CanvasWidgetRenderer::setupBuffer(canvasBuffer, CANVAS_BUFFER_SIZE);When I create screens with lineprogressbar the generated files all have :static const uint16_t CANVAS_BUFFER_SIZE = 4800; uint8_t canvasBuffer[CANVAS_BUFFER_SIZE];   CanvasWidgetRenderer::setupBuffer(canvasBuffer, CANVAS_BUFFER_SIZE);Is it better to have one function (CanvasWidgetRenderer::setupBuffer(canvasBuffer, CANVAS_BUFFER_SIZE);) called in main.cpp or have multiple screen call (CanvasWidgetRenderer::setupBuffer(canvasBuffer, CANVAS_BUFFER_SIZE);) ?The application is running fine with multiple calls, but I was just afraid this will create memory problem if the buffer isn't returned during teardown.Thanks for the help!

I just designed a board with the new STM32F730Z8 value line with embedded USB high speed PHY. I'm using a 16MHz external crystal and I am using the default code generated with CubeMX. It fails in the USBD_Init function. Following it through at first glance I found that in usbd_conf.c there is this line:hpcd_USB_OTG_HS.Init.phy_itface = USB_OTG_ULPI_PHY;I changed the interface to USB_OTG_HS_EMBEDDED_PHY but it still fails. I imagine there could be some other settings that may be wrong as well. Any guidance on this?

Hi,I use SWD interface to configure my STM32 board.It all worked out, but I changed #define and moved to a part of the program that disabled the sw interface.Now my STLINK/V2 can not connect to the device.Do you have an idea to erase the chip or restore the SWD interface?#else /* DEBUG */ /* sw interface off*/ // GPIO_InitTypeDef GPIO_InitStructure ={0}; // // GPIO_InitStructure.Mode = GPIO_MODE_ANALOG; // GPIO_InitStructure.Pull = GPIO_NOPULL; // GPIO_InitStructure.Pin = (GPIO_PIN_13 | GPIO_PIN_14); // __GPIOA_CLK_ENABLE() ; // HAL_GPIO_Init(GPIOA, &GPIO_InitStructure); // __GPIOA_CLK_DISABLE() ; // // __HAL_RCC_DBGMCU_CLK_ENABLE( ); // HAL_DBGMCU_DisableDBGSleepMode( ); // HAL_DBGMCU_DisableDBGStopMode( ); // HAL_DBGMCU_DisableDBGStandbyMode( ); // __HAL_RCC_DBGMCU_CLK_DISABLE( ); #endif

We are using your TS512 with (+/-15V rails) as a low current (1mA), 10V voltage follower. We have a test case where the output the TS512 is pulled to a 19V/100mA source for just 600us, and I am trying to assess whether this transient could internally damage Q29 or Q30 or anything else in the o amp (referring to TS512 schematics from datasheet, see also below).My understanding is that during such transient the negative feedback would try to pull the output down to -15V to counter back that transient, hence Q29 would be cut-off and R13 would prevent the B-E junction from breakdown. On the other hand Q30, I think it would be almost fully "on", which would potentially create a differential voltage across R14 of 19-(-15)=34V. The question is: 1. Would the output still limit to 25mA so would R14 be safe -and by extension TS512- during those 600us)?2. Is there any other considerations to take into account to assess the robustness of this part under this transitory?NOTE: This question and

We are using an ST1S12GR device and the input current is >2.5mA even with only the feedback loop connected and ENable pin connected to Vin. Feedback resistors values are 220k resp. 59k. According to Datasheet Table 8 (“Electrical Characteristics�?) Quiescent Current Iq should be max 650uA when non-switching, so how can we reduce current consumption?  NOTE: This question and answer originated from a customer support case which was handled by us.

I would like to use TSC103 in a system where the power line to be monitored is 48Vdc (63V maximum peak or steady state) and the ADC acquisition system is powered by a 5V voltage independent from the 48V line; so my doubt is if any failure can occur if the main monitored 48V line is present but 5V for Vcc is missing. Datasheet is not explicitly mentioning this operating condition, will it work without risk of damage? NOTE: This question and answer originated from a customer support case which was handled by us.

We are considering to use L6924U for a new design for a battery charging circuit in our industrial wireless remote controller project. If we set up L6924U for AC input (MODE grounded), do we need to do anything with IUSB pin? Can we just ground it (w or w/o resistor) or leave it floating or tie it to IAC pin?

We are using L6470PD driver IC for driving 2-phase stepping motor. Problem is related to external clock and internal clock setting in L6470.In fact, we noticed different motor rotation speed when we switch between external clock of 16MHz and internal clock of 16MHz generated by OSC. We realized that motor rotation number in using external clock is slower x 0.666 than using internal clock in 16MHz clock. This is an important aspect of our application where we have to use internal and external clock with exactly same resulting motor speed.By the way, is there any method of changing motor speed without changing SPEED parameters?NOTE: This question and answer originated from a customer support case which was handled by us.

I'm using the SPWF04SA module to write sensor data to Azure Storage Table service by sending https POST request over a socket connection. The application works fine for some hundred requests over several hours but occasionally a WIND: NtpServerDelivery message just occurs when I have opened the socket for writing which makes my program hang (yet unknown reason).To circumvent this problem I wanted to control the SPWF04SA ntp client so that the WIND: NtpServerDelivery messages occur at a time where I'm just not opening a socket.I can switch off the NtpServerDelivery with AT+S.SCFG (ip_ntp_startup = 0) command but I'couldn't manage to change the refresh interval with AT+S.SCFG (ip_ntp_refresh = xxxx). Whatever value I write to the 'ip_ntp_refresh' variable (success controlled by reading it back), the WIND: 'NtpServerDelivery' events comes in every 60 minutes.Is there something I could be doing wrong?Is there a way to control the timing of the WIND: NtpServerDelivery messages?

Hi, I can't get the correct fix rate for x-nucleo-gnss1a1Using following command:$PSTMSETPAR,1303,0.1,0$PSTMSAVEPAR$PSTMSRRwhat I expected is update rate 10Hz, i.e., the timestamp is increasing 0.1 each time. However, the result isabove the red line, one can see that it is updating at the rate of 10Hzbelow the red line, it is updating at the rate approximately 3HzIf I reset the program, it will maintain 10Hz for about 1 sec, then back to 3Hz.If I power off the stm32 and power on, it will maintain 10Hz for a while, then back to 3Hz.Any idea or advice will be appreciated, thank you so much.

Hi,I'm planning to buy an STM32MP1 discovery kit (when available) and I'm wondering how to get access to the distribution package. I read on wiki.st.com that I have to request these rights to my ST support contact but I can't found out how to do it.Thanks in advance

Hi. When I call HAL_NVIC_SystemReset(); or NVIC_SystemReset(); the system just freezes up instead of restarting. I figured forget about it and moved on to try out the watchdog, well the same thing happens. Watchdog is enabled and working fine, then I enter an infinite loop to try it and after it times out the whole chip gets stuck.I don't know why this is :(

I update my Stm32CubeMX to 5.0, and open an old project , regenerate the code with ToolChain SW4STM32I have some floder missing, I must recreate the floder and copy the files into it.The old version of Stm32CubeMX is OK.Is there a solution?

We are building a 115kHz SMPS transformer that is being used in a circuit using a VIPER06HS. It is in the circuit with my transformer that is outputting 5 volts at 200mA the OCP is tripping off the VIPER unit. I would like to know how the OCP works. If my transformer was oversaturating would that cause the OCP to trip?NOTE: This question and answer originated from a customer support case which was handled by us.

I have a question for the configuration of the static registers via the I2C bus.The easiest way to configure the Area RF protection and Area ending point registers, (address 0x0004 until 0x000A), is to send a I2C write message to program all 7 data bytes in one I2See the table 11 snapshot from the datasheet:However, data is not programmed. Any suggestion why it does not work?NOTE: This question and answer originated from a customer support case which was handled by us.

Hello,I have a very weird behavior...When trying to access external synchronous PSRAM.I see the clock and cs change only if I stop and starts stepping inside the while(1) loop below. When doing "go", there is no clock nor CS changes.I tried to add delays as you can see, but nothing helps.#define FPGA_BANK_ADDR 0x64000000   __IO uint8_t value; __IO uint8_t * volatile psramaddress = (__IO uint8_t volatile*)FPGA_BANK_ADDR+2; while(1) { *psramaddress = value++; rd_2 = *psramaddress ; HAL_Delay(500); }Is there any idea ?Thanks

Prefer to have versions older than the STM32CubeF3 v1.10.0 release. Scot over to the website to see if they have options to download previous versions but to no success. Please help!
