Solved

Hello,​I have some question about use STSPIN840.Page 19 in datasheet, R_EN and C_EN's value are 39KΩ and 10nF.In the graph that is the basis of the recommended value, the value of V is 3.3V.​Also in page 18, FAULT and EN pins in MUC are tied Driver's EN/FAULT pin.​And this typical schematic, each EN/FAULT pin's resistor is tied V_DD.Do they have to be tied to 3.3V or is it okay to configure as shown in Figure 9?(In this case, VDD means the MCU's EN pin is 3.3V?)​A lot is difficult because it is the first time to design.​Best regards,Minkyu Kim.​

Hi All,How do I generate a generic Makefile from STM32Cube ide? Preferably for L56 series. Currently when I create a project the Makefile option under toolchains inside the cubemx is grayed out. The CubeMX is installed as part of IDE. thanks,

 I'd like to start with that using the STM32CubeIDE and modify from there to get my own code to work. I looked in the example space and there are no code examples for the F3 series. Thank you for all pointers.

On STLink-V3MINI (https://www.st.com/resource/en/data_brief/stlink-v3mini.pdf) there is a neat connector used for the STDC14 connection, which has the top and bottom sides of a box header but no ends. This means it takes up a smaller footprint space than if it was a normal box header, but is still keyed (unlike just using a pin header with no plastic sides).Can anyone tell me where to find a connector like this, for my own boards?

Hello,I have a STM32CubeMX installed on an offline cumputer (that cannot be changed!)I would like to install the last firmware for L0 familly, so I download:stm32cube_fw_l0_v1110.zipstm32cube_fw_l0_v1113.zip (patch only file)From local, there is no problem to install the version 1.11.0. But when selecting the 1.11.3 file, there is an error "corrupted or not recognized package)How can I install the 1.11.3 FW version? I tried to extract the 1.11.3 zip in the repository directory. But after that, the version 1.11.3 do not appear in the Packages Manager, and version 1.11.0 is no more there!Thank you for your helpAntoine

i want to have my CNC system moments feedback, which involves displacements of 0.01mm sensitivity

Hello, The stack size is defined by a macro definition, INTERFACE_THREAD_STACK_SIZE inside the "ethernetif.c" file located under: LWIP/Target.I had to manually increase the size due to stack overflow and any new code generation via CubeMX overwrites those changes. Since code generation always defaults the size of INTERFACE_THREAD_STACK_SIZE to 350, I would hope that there would be a way to adjust it via CubeMX?

HiOur marketing needs to know how much space they have for translation etc. and requested if we can show this visually on the screens. The easiest would be if each textarea had a box or border, which indicates the size.Is there an easy way to add a box/border to the textarea that I can see visually how big the textarea is? It should be applicable to the whole application and every textarea with or without wildcard.Thanks a lot.Best regardsMarco

I'm working with a custom tag that needs to be powered by the radio wave field between a select command and a read one.Is there any way to accomplish this using the API or it must be done on register level?

I've recently done a clean install of STM32CubeIDE, and after went for the x-cube-mcsdk setup.The motor WBench cant generate the code because CubeMX is not installed... But in fact CubeMX is now embedded in STM32CubeIDE.How can this issue be solved? (see screenshot )-d

Hello,I'm wondering if there is a an alternative to TICK_INTERVAL_MS constant which is deprecated. It is said that handleTickEvent() function is called by the Application on the current screen with a frequency of Application::TICK_INTERVAL_MS.For the moment I've changed the frequency at which handleTickEvent() is called with this code :/** * Has to be called from within the LCD IRQ rutine when the Back Porch Exit is reached. * * Has to be called from within the LCD IRQ rutine when the Back Porch Exit is reached. */ virtual void backPorchExited() { static int cnt = 0; static int modulo = 2; if(cnt%modulo ==0) { swapFrameBuffers(); tick(); } cnt++; }(Here i got the same LTDC frequency but the frequency display is divided by 2)regards,AJT

We have ordered ST25-TAG-BAG-U. I want to write a password protected data on ST25TV02K tag from it.I have downloaded ST25 anroid application to communication with tag.Using Application I can read & write NDEF text on tag using ISO/IEC 15693 protocol but can not do password protected of that tag.when I tried to set present password it display "command failed" message and when i tried to read register value it display "Error while reading the register values!" I have attached screenshot for reference.I have read ST25 Android™ NFC tap application user manual to set password but it can not help.Please help to write password protection data in ST25TC02K using android applicationThanks,Jignesh Patel

Hi,I was playing around a bit with the clocks.I had it set up to run on 48MHz from MSI.I then choose PLL on 64MHz but couldn't get the 1µs timer pulse I wanted (prescaler on 63 for TIM2 got me something about 1,178µs)I then wanted to get back to MSI, but configuration tool found an issue with RCCFlash latency is marked as a problem with 3 waitstates.I can do nothing about it since its greyed outany idea how I can get back to 48MHz MSIcheers,Bob

Hi,I am working on a project where using external bin lib files is forbidden for safety and security reasons. Is the TouchGFX source code available ? Do we need to buy a license or something like that ?Thanks,Olivier

Hello,TouchGFX version: 4.15.0STMCubeIDE: 1.4.2I need some help, I am seeing some strange behavior from a custom module I am creating. Basically, when I am forced to use a PainterRGB888 to color a circle, TouchGFX will halt when calling showBaseModal()Here is my class:#include <gui/containers/modal/modalBase.hpp> #include <touchgfx/Color.hpp>   modalBase* modalBase::getInstance() { static modalBase gModalBase; return &gModalBase; }   modalBase::modalBase() { mInternalWidth = 212; mInternalHeight = 159; mCornerRadius = 10; mEdgeBuffer = 30;   mMainContainer.setX(0); mMainContainer.setY(0); mMainContainer.setWidth(272); mMainContainer.setHeight(480);   circleTopLeft.setPosition(mEdgeBuffer, 161, mCornerRadius*2, mCornerRadius*2); circleTopLeft.setCenter(mCornerRadius, mCornerRadius); circleTopLeft.setRadius(mCornerRadius); circleTopLeft.setLineWidth(0); circleTopLeft.setArc(0, 360); circleTopLeftPainter.setColor(touchgfx::Color::getColo

Hi,We have used L6208 for driving bipolar stepper motor in our application. We would like to run the motor in full step mode. We implemented the circuit given in the datasheet on our PCB. When we program and try to drive the stepper motor, the shaft rotates one step forward and one step backward.The clock pulse which we are supplying to CLK pin is 50ms.The following are the connections of the bipolar stepper motor with L6208 DriverCoil 1+ve Terminal to Bridge A Output 1-ve Terminal to Bridge A Output 2Coil 2+ve Terminal to Bridge B Output 1-ve Terminal to Bridge B Output 2I am posting a snapshot of the waveform observed after probing the outputs of Bridge A and Bridge B of the Driver.Bridge A - GreenBridge B - YellowLooking at the waveform, I feel that one of the bridge is not functioning properly and hence this to and fro motion of the motor shaft.Request you to kindly let me know if you know how to fix this issue.

I've configured a timer for Output-Compare on a pin that goes to a stepper motor. However is there a way to configure the timer such that it outputs a certain number of reload events / pulses and then stops completely.In software, I understand I can accumulate the count in the TImer ISR and then stop the timer once the desired count has been reached, but would prefer to have the timer stop automatically.Also is it recommended to route the output to a timer input to verify the number of pulses generated? Not sure how others implement driving a stepper motor, but I need a highly precise position!

I need to detect if there is a comparator state change inside a PWM pulse. I want to look for this a little after the PWM rising edge and stop before the PWM falling edge.The PWM is running in center aligned mode.RM0440, Rev 4, STM32G4 Reference manual:1) Page 884 last paragraph says: "Whenever the roll-over event is used for blanking or windowing, the ROM[1:0] programming applies for defining when it is generated"2) Page 894 first bullet says: "In up/down mode (UDM bit set to 1), the counter reset event is defined as per the ROM[1:0] bit setting.Section 27.5.49, page 1028 defines ROM[1:0]. It says for case 00: Event generate when the counter is equal to 0 or to HRTIM_PERxR value01: ...Let's say I program:Period to 1000, PWM to 400 and compare 1 to 500. This means from 0 to 400 the PWM output is low, from 400 up to 1000 down to 400 the PWM output is high and then from 399 to 0 the PWM output is low. I want the blanking window to be open between 500 up to 1000 down to 500.I then program

Hi,I am using STM32H743VIT6 for prototyping, but for production I may not use such powerful micro-controller.How to find pin to pin compatible replacments for this micro controller?

I am trying to develop a smart tumbler.Smart tumbler measures the amount of water you drink per day.Place LPS33HW on the bottom of the tumbler and measure the amount in water.I think the LPS33HW should come in contact with water.Water is eaten by people.Does the LPS33HW contaminate water?Or is there another way?The amount of water to be measured is 10 to 700 ml.I look forward to your answer.

I have a pair of DK1 boards I just received that I wanted to get working with wifi direct, but neither even can show a wlan0 interface. In the past I have used a DK2 with buildroot and got the wlan0, and a coworker used stock yocto build on the DK2 and said wlan0 was there too. Is there some problem with the DK1?#first check:root@stm32mp1:~# ifconfig -aeth0     Link encap:Ethernet HWaddr 00:80:E1:42:70:CC           UP BROADCAST MULTICAST MTU:1500 Metric:1         RX packets:0 errors:0 dropped:0 overruns:0 frame:0         TX packets:0 errors:0 dropped:0 overruns:0 carrier:0         collisions:0 txqueuelen:1000          RX bytes:0 (0.0 B) TX bytes:0 (0.0 B)        &nbs

Hi All, I am just getting started with the  B-G431B-ESC1 evaluation kit. I wasn't able to find it listed as a development kit in the motor control workbench and the instructions in the user guide weren't entirely clear on this for the initial configuration. From what I understand, I should use the motor control workbench to generate the base project code to load onto the development kit, before running the profiler, meaning I am obviously unable to continue without this step. Am I missing it in the menu somewhere? Are we supposed to configure a "custom" project and drive stage for this board (though it would be greatly appreciated if someone could share an example MC workbench project with me)Thank you all for your support!

Hello. This is my first post here. I'm pretty unexperienced at the hardware side of MCU's and I want to debug my STM32F304P6 processor (on an unofficial board) through debugger of STM32F407VG Discovery Board. I connected SWD pins ( 2nd to CLK, 4th to DIO, GND to GND and 3v3 to 3.3V on Discovery) and unplugged CN3 headers. And I get can not find target error. Than I tried to connect 5th SWD pin with NRST on board but the result is same. I read the documentation and I don't know where am I doing wrong. ThanksPS: I tried the same method with STM32F103 too. Result is same. Discovery board works well.Unofficial STM32F034P6 Board:

Hello,I would like to implement an I2C master on an STM32F103. It's pretty straightforward to select the IO's using cubeMX and to generate the code, but I don't want to use either of the available pins for I2C (PB7,PB6 or PB9,PB8). I need to use PB5 as SDA and PB4 as SCK. Is there a way to do this in cudeMX/cubeIDE without writing a custom I2C ?Regards,Mawaba.
