Solved

Hi,probably my problem is very simple to solve. I have a swipe container with a static graph that fills almost the entire screen. My problem is that I can't swipe the container because the static graph widget processes the touch event, even the click listener is not enabled.Is there a simple solution to pass the event to the swipe container so I can move it?Thank you very much.Best regardsDominik Schmid

Posted on July 04, 2017 at 15:47Hello Team,As per STM32F769I-DISCO board schematic, I understood it should be Bypass clock source.But default cube project gives selection as Crystal ceramic. Why it is ceramic crystal?Request you to help me which one I should select for STM32 -DISCO board?

Hello, I am using a p-Nucleo-wb55. I would need to get data from vbat channel and the internal temperature channel. I used the example for internal temperature and it works but I am not able to add the reading of vbat value. Am I supposed to use one rank per channel? How do I add a rank using the .ioc file ?  Thank you

I looked into the radio_driver.h library, Radiolorabandwidths enum there is enumeration of lora bandwidths but the value assigned seems to be random with respect to RM0453 document on Bandwidth on lora. Is the library is correct or need modification?

I am writing SW in python to eventually program the STM32G051K8 over the UART from a BeagleBone Black (BBB). For testing I am doing it from the PC with a TTL-232R-3V3-WE USB to TTL Serial adapter. At the moment I am making routines for each command. What I am discovering, is that if something happens and a command returns a NAK, all of the following commands return a NAK and there is no recovery other than a HW reset. For me it is not a big, deal as long as I know that is how it is supposed to work. Right now I have the Get Command, Get Version, and Get ID commands working. And I am having some issue with the Get Read command. But after I do, none of the other commands that were working now work, they always return a NAK, until I ground the reset pin. Then I send the 0x7F to reset the baudrate, and I can continue. Is this how it is supposed to work? Like I said, if that is the case I can work around it. (right now the PC cannot automatically toggle the reset line, I have to do that man

I have used CubeMX to configure the HAL comparator driver to trigger an interrupt on the rising edge only, however the interrupt seems to occur on both edges. I checked the EXTI registers and everything seems correct. I then thought that my voltage supply might be noisy enough that it was causing transitions despite the high level of hysteresis that I have set. I used an oscilloscope to view the comparator output on a GPIO pin and there were no spurious transitions that I could see. I have no idea what the problem is at this point. Does anybody have any ideas? thanks.

simple 3 Button Touch Key application using TSC on STM32L431 goes wrong when VDD power supply drops from 3.3V to approx 3.0V (just above BOR level) then recovers to 3.3V.All 3 Buttons are read back as active from this point on. Has anybody experienced this behaviour?Solution is to make a software reset, if this scenario is detected.

Please Share, suggest suitable library or sample codes for Mounting SD card as Mass Storage with Virtual COM port option.Thanks

Hello all ~​I have STM32MP157A-EV1 and STM32MP157C-DK2. I want to change system time and keep it. But It is not working well. Below is the test log on EV1.root@stm32mp1:~# date -s "20031025 18:00:00" Sat Oct 25 18:00:00 UTC 2003 root@stm32mp1:~# date Sat Oct 25 18:00:03 UTC 2003 root@stm32mp1:~# root@stm32mp1:~# hwclock --systohc --utc root@stm32mp1:~# hwclock 2003-10-25 18:00:18.632338+00:00 reboot .... root@stm32mp1:~# date Mon Jun 27 03:19:28 UTC 2022Am I miss something?:sad_but_relieved_face: thanks. 

Hello everyone ~​My custom board has RGB(LTDC) and HDMI display interfaces. We want to display same screen on same time.(duplicate mode)So, LTDC interface connected to local LCD and HDMI transmitter(sii9022).&ltdc node of my dts is below ..&ltdc{ pinctrl-names = "default", "sleep"; pinctrl-0 = <&ltdc_pins_mx>; pinctrl-1 = <&ltdc_sleep_pins_mx>; status = "okay"; /* USER CODE BEGIN ltdc */ port { #address-cells = <1>; #size-cells = <0>; ltdc_ep0_out: endpoint@0 { reg = <0>; remote-endpoint = <&sii9022_in>; }; }; /* USER CODE END ltdc */ };and we can display both screen successfully as below picture. However, unfortunately my LCD`s resolution is 1280x800.and linux platform doesn't have this HDMI resolution mode.so my LCD was displayed as below...Therefore, I want to add 1280x800 mode to HDMI. Is there any guide article on wiki?Thanks a lot !!!

I have bought ST25R3911B-Disco board for proof of concept.I need to be able to read the tag for identification from ~50 cm.currently I have ST25TA tag and it I can read it from ~3cm. I understand I need to buy tag ST25TV with NFC type 5.can you guide me how I get the ST25R3911B-Disco to work in long ranges ?what kind tag I need to buy ?will I need to change the setting in the registers map to get long ranges ?will the disco be able to provide long range readings ?if not what reader/eval board can do the job?

What are the best chip/settings to read multiple RFID 14334A tags? What should I look at when selecting chip?I need to create a reader that needs to read playing cards (14334A) from the table.Currently, I have a setup with AS3910 chip. It works fine while 1-2 cards go through its field simultaneously. 1) First issueIf I stack one card on another it can read only up to 2 cards like that. When I stack 3 cards it can't.2) Second issueIf cards (2-16) are in its field from the start it usually then can read just one card and sometimes more. (No idea why. Even if I leave the cards in the same place)So I wonder what is responsible for these limitations? Is it the wrong settings, old chip, wrong protocol, or just the physical limitations of RFID technology?Thanks!

There is an issue with a number of variables in the example machine conf files in the 4.0.0 (Kirkstone) ecosystem. The variable names have been changed in meta-st-stm32mp/conf/machine/include files but have not been changed in the addons layer example machine conf files to match.

Hello there,I have sensorless 3-phase bldc motor. I am using MC Workbench for Sensorless FOC algorithm with STEVAL-SPIN3201 board. I've run my motor at torque mode and it seems okay. But, when I loaded motor does not produce any torque and immediately stops. What can be the problem? I've attached screenshots of GUI settings file.

I bought a stm32f429i-disc1 board and I want to learn how to communicate to stmpe811 with I2C protocol, now I'm a little confused. According to stmpe811's data sheet, its address is 0x82 because its A0 pin is connected to ground, but board's schematic(MB1075) shows that address is 1000001(7 bit). Is the address on schematic missing a 0 on the far right?

i´m new here, and i´m starting to work with STM32F103C8 (blupill)I´ve created a very simple code. It´s shown in image down.The problem is:The editor doen´t recognize the variable type int8_t and int32_t (probably int16_t too).And when a try to build the code, the editor show me a message: adc0 undeclared.I don´t know how to resolve this. I´ve tried to declare stdio, nothing changes.Does anyone could ,pelase, help me??Thanksss

Hello.I am in need of inputting large strings of text (larger than the width of the screen) using keyboard. I have managed to get a working keyboard, but after increasing the buffer size, the text is being cut off after it leaves the widget area.I want to be able to scroll the written text left and right, or maybe even up and down. This would require me to somehow get a Scrollable Container as a parent for the text area, or rather the Rect textAreaPosition (which is part of Layout structure), which the text is being drawn on.I have managed to increase the size of drawn text dynamically by calling setLayout(&layout) after changing the size of textAreaPosition, which means that Scrollable Container could work (although I wonder how will calling this method so fast impact the performance). The question is how to add Scrollable Container as a parent of Rect textAreaPosition, without changing the provided Keyboard widget code? Is it doable? Maybe there is an easy way of doing what I wan

Hi,me and my team are working on a project on STM32MP1-DK2. While everything is working fine on the previous ecosystrem release (v3.1.0),after updating to the latest release v4.0.0, our demo stop to work, even after recompiling.This is caused by the following code:wl_display * display = wl_display_connect(NULL); if (display == NULL) { std::cout << "can't connect to wayland display" << std::endl; return false; }wl_display_connect keeps returning null and thus I cannot get the current Wayland display.What's more interesting is that even the built-in "weston-info" tool has the same issue and in fact it doesnt work.Can anyone help?Thank you
