My powerStep01 is constantly triggering the Overcurrent alarm whenever I give a movement command, even if there is no stepper connected. What could possibly be causing this? Previously I was getting a similar effect on the L6470 chip. When I turned off the overcurrent shutdown feature the chip fried and apparently took out GPIO25 of the Raspberry Pi that was command it. In both cases, the motors never moved.

I used STM32CubeMX to create the initial code for my STM32CubeIDE project. But looking over the generated code, I realize I need to make a change. How do I get back to STM32CubeMX from within STM32CubeIDE in order to modify and regenerate the code?

Hi,I wanted to generate interrupt on pins PC14 and PC15 on NUCLEO-F722ZE board but it doesn't work. In the board documentation I found that jumpers configuration should be as per screenshot. Since elements there are pretty small and I don't want to destroy my board can someone confirm if this is the reason why interrupts on pins PC14 and PC15 are not triggered?For other pins it works (I used the same code as below, only changed pin numbers). I also generated code in CubeMX and I don't see any difference.void EXTI15_10_IRQHandler (void) { GPIOB->BSRR |= GPIO_BSRR_BS14; //Light LED   if (EXTI->PR & EXTI_PR_PR0) { EXTI->PR |= (EXTI_PR_PR0); flagInterrupt = 1; } }   void Gpio_Config (void) { /* Enable clock for port C */ RCC->AHB1ENR |= RCC_AHB1ENR_GPIOCEN; /* Set the 15th pin to input */ GPIOC->MODER &= ~(GPIO_MODER_MODER15); /* Configure pull up on pin 15th of port C - set value to one == set bit 0th */ GPIOC->PUPDR |= GPIO_PUPDR_PUPDR15_0;

Dear Community,as a hardware developer I'm working on a project with ST25DV Tag.Now I'm facing some problems with the NFC Antenna and would like to try out some double sided ones. I have some example boards and also a list of ST approved antennas but I want to fit the antenna size to my application. That's why I need some formula to calculate.Unfortunately, I can't find any useful information on designing double sided antennas.Do you have any experience with it or do you know good whitepapers or tools to calculate?Of course I know the ST Antenna calculating tool but that's only for single sided antennas.Thank you very much!

Hello,I'm having difficulty in reaching the maximum RPM specified by my battery and motor combination using the B-G431B-ESC1 dev board. I'd expect about 10,000 RPM with a full battery but am only able to achieve ~4000 before getting a speed feedback fault. I'm using an 11 pole-pair motor rated 480KV at 21V (5S Samsung 18650 25R cells). I've used an LCR meter to measure the motor characteristics and have input them into the motor control workbench. I've had to manually adjust PID Gains in the advanced tab in order to get a successful startup as the motor profiler simply has not worked with my configuration. When I manually ramp up the speed, regardless of how quickly (1s ramp or 10s ramp), it'll cut out and report a speed feedback fault at ~3800 to 4200 RPM. This works out to around 42k to 46k eRPM that it trips at. Currently this motor is just sitting on my bench, no-load. I've commented out the "ESC applicaton" calls from main.c as the "waiting for signal beeps" were interrupting the

I’m attempting to optimize a process of loading a large file from eMMC flash memory directly into a SPI device with 8 data lanes. Originally, I meant to use peripheral to peripheral in the DMA component that comes internally with the STM32L5 series. However, the hal32l5xx_hal_mmc driver states“No general propose DMA Configuration is needed, an Internal DMA for SDMMC Peripheral are used.�?I’m trying to determine the most speed-efficient way to manage this transfer. I’m currently experimenting with directly calling the OctoSPI memory mapped location as the data buffer in the HAL_MMC_ReadBlocks_DMA function but I’m having little success.Are there any examples of using MMC Peripheral to Peripheral DMA communication? How would this process be achieved? 

Hello,I am writing a code to initialize the BMI055 IMU on my STM32F765. To do so I am using the HAL libraries to enable the SPI connection through DMA and the drivers provided by Bosch: bma2x2 and bmg160.The two sensors work perfectly when only one of the two is enabled, but together they don't work.// Init Gyro int32_t bmg160_sensor_init(void) { SPI_routine_gyro();   com_rslt_2 = bmg160_init(&bmg160);   com_rslt_2 += bmg160_set_power_mode(BMG160_MODE_NORMAL);   v_bw_u8 = C_BMG160_BW_230HZ_U8X; /* set gyro bandwidth of 230Hz*/ com_rslt_2 += bmg160_set_bw(v_bw_u8);   /* This API used to read back the written value of bandwidth for gyro*/ com_rslt_2 += bmg160_get_bw(&v_gyro_value_u8);   bmg160_set_intr_output_type(BMG160_INTR1, 0);   // 1.

Hello,I'm working on an a project that uses an ST32G474, and it needs to run two different/independent applications. The project requires that from a reset, the device boots from Bank2 every time. The application in Bank2 will then decide if it is ok to then jump to, and start running the application that is stored in Bank1.The dual-boot example from ST isn't exactly what is needed, because it flips the BFB2 option bit during each boot, to toggle between banks. My application requires to always boot from Bank2, and then jump to Bank1, without going through a reset operation.From reset, I'm able to get App1 to run from Bank1 when BFB2 is cleared, and also from reset, I'm able to get App2 to start and run from Bank2 when BFB2 is set. However, when I try to jump from App2 to App1, I'm not succeeding. Through various different tests, it looks as though App2 somehow either jumps to itself, or I jump somewhere and just crash.I've tried to figure this out reading various different posts about

The steps to reproduce this build error:Use TouchGFX Designer to create simple GUI by using the template for STM32F769-DISCO.Build and Run it on target -> OKThen open the .ioc using STM32CubeMX to configure for Virtual Com Port.Use STM32IDE to open the project , build and run -> OKBut when we open the project using TouchGFX designer to edit some GUI, it had build error on target (simulation is ok).   Core/Src/main.c:24:10: fatal error: usb_device.h: No such file or directory     #include "usb_device.h"         ^~~~~~~~~~~~~~    compilation terminated.It compains as it cannot find the file that CubeMX just generated from step 3.Are my steps wrong to cause this? How to resolve this?

Hello, I am working on a Cortex M4 and I'd like to add some power-saving features to my program and figured I'd need to detect user activity. For this reason, I'd like to detect if a user hasn't tapped the touchscreen for x [e.g. 5] seconds, and if so:dim the screen's backlight as much as possible or, better yet, manually set the display to standby and disable touch sensing.clock-down the MCU.if a HW button is pressed, I'd like to wake the display back up again, and increase the clock again.Furthermore, I created a dedicated "charging screen" (basically only an animated battery filling up some bars in a loop) from which I want to go to power-saving mode even when a user touches the screen in order to charge faster. So, my questions are:Where is the `TouchController::sampleTouch(...)` method even called? I haven't found it anywhere in the code...Would the `TouchController` be the best place to put the logic for detecting inactivity?If not, where should I best put this kind of code?Thank

Hi,I have a NUCLEO- F401RE board with the X- NUCLEO-S2868A2 expansion shell and i want to test the examples, provide by ST, that the X-NUCLEO-SUBG2 folder contain.I import the border router and both of the udp's projects to see how they works (one by one of course) and in every of it i have the same errors. I do not change anything in the projects, just import and build it. Do you know what is happening?Thanks. In this image you can see the errors.

Hi,I can't find any examples of using commands in the statemachines.I want to create a tilt sensor, by using 2 statemachines, 1 is monitoring x axis, the other z axis.To keep it simple i will add the code for the x axis only . This statemachine setup should do the same as this equivalent in c : If ((x<THRS1) || (x>THRS1)) -> trigger the interrupt pin This does not seem to work, what do i overlook?Triggerlevel goes from 1 to 255, i use this to set the sensitivity of the detection// 1 get the current x, y , z values to determine how the PCB is fixed in the cabinet lis3dsh_update_xyz(); triggerlevel = MAX_SENSITIVITY/sensitivity;   buf[0] = CTRL_REG3; buf[1] = 0x48; // INT1 pin active '1' if(! lis3dsh_write(buf,2)) return false;   buf[0] = THRS2_1; buf[1] = (lis3dsh.xyz.raw.x/256) + triggerlevel; //threshold to identify angle if(! lis3dsh_write(buf,2)) return false;   buf[0] = THRS1_1; buf[1] = (lis3dsh.xyz.raw.x/256) - triggerlevel; //threshold to i

Hi,I am trying to debug in engineering mode with the STM32MP157A-DK1 through a external ST-Link V3 but i am not being able to get it to work. I attacht the error gotten, as well as pictures of the connection and the debug configuration in Cube IDE. The image thas shows the debug configuration has the OpenOCD option configured, however i have also tried the GDB option but the board is not even found in this case. Thank you in advance.

I register MDMA call backs, for example XferBufferCpltCallback, XferBlockCpltCallback, etc. using the HAL_MDMA_RegisterCallback() function. But the callbacks never got hit. These callbacks are called from stm32h7xx_hal_mdma.c/HAL_MDMA_IRQHandler(). HAL_MDMA_IRQHandler() in turn is called from stm32h7xx_it.c/MDMA_IRQHandler(). However, in my source tree , both CM4 and CM7, DMA_IRQHandler() is not in stm32h7xx_it.c as generated from CubeMX 6.1.1. And MDMA ISR is not in the vector table in startup_stm32h745bitx.sI have looked at NVIC1, NVIC2, MDMA in CubeMX and can't find anything that would get MDMA_IRQHandler() to be generated. I would aprreciate it if someone let me know how to solve this problem.

We are trying to locate the POWERSTEP01, but we see that it is impossible, since the distributors do not have stock, and the forecast dates are long.Is it possible to get the device in ????we need it very urgently.

Hi I met a problem with reading/writing an NDEF message to ST25DV04k tag with iPhoneXR.I will first introduce some background of the problem.I use NFC Tools and NFC tap(ST) appsWhen the tag is new, I used NFC Tools to write and read NDEF messages successfullyAt some point, I wrote some bytes to the tag by NFC tap( I think the command is writesingleblock) and the NFC Tools can no longer write/read NDEF message to the tag.Read/write bytes on NFC tap is always working fine.​The area1 size is 512ByteI looked up AN4911, and reset the CC bytes as E1 40 40 00 or E1 ​40 3F 00, but my phone still can not recognize the tagMy question is how to set up the ST25DV04k tag in order to be recognized as an "NDEF writable device" ​YuechuanBest Regards
