Hi there!I am new to STM8s Discovery, could someone suggests me how to print the values of variables in the program? it is more convenient if i can do this but I have no idea how to make it. Thank you very much ! Morris

Hello,We are using x-cube-usb-pd v3 library to implement source/sink application for our product. We've ported it to use on an STM32F030CC and using PTN5110 chip for TCPC controller. We are using configuration USBPD_TCPM_LIB_PD3_CONFIG_1.We have tested sourcing 5V 3A and is working well and now we'd like to go over 5V and want to support different voltages such as 9V and 12V.However, we run into problem where we can't seem to do this.On our hardware, we know we can support 9V or 12V output but for some reason, as soon as we turn the VBus to 9V, the vbus seems to disappear. I've collected a log again and attached here. I am testing with a phone this time (Huawei Redmi Note7). I've also monitored the VBUS on a scope and I can see that it tries to go up ( to around 8V) and then it goes down to 0V. I also scoped the EN_SRC pin and that is pulled low at the same time 8V disappears.It seems that before all that happens, we get an Hi voltage alarm and Low voltage alarm. I'm not sure if these

Hi,How to create custom containter that has moveAnimator mixin included? Is it possible?I want to create notification, which is operated using: notificationContainer.show()The custom container would implement this show() method, which would call startMoveAnimation() to itself, among other stuff.I can add moveAnimator mixin to container in this in view, but then I need to call the startMoveAnimation etc. routine in every view, instead of just calling show() and letting container deal with the implementation.How would I create custom container class that has MoveAnimator mixin?Designer generates it like this:touchgfx::MoveAnimator< notificationContainer > notificationContainer1;I cannot figure out how to create such class. Thanks!

My system have tens of pages, and have 3 hardware buttons to change the LCD backlight.When change the backlight, it is needed to display a small window on the current page.After finished the changing, the small window closed.​I know I can create ModelWindow in each page, and display it in handleKeyEvent.In this case, I need to create the same code for each page. It must be very hard.Is there any simple method to do it?Thanks!

Hi All,is there any mcu in SPC5 family with interface for unmanaged raw NAND chips, e. g. External Bus Interface or something else? I've checked modern gen. datasheets and haven't found any mentions about NAND. Thanks for any help

My question is this - is one presently being worked on?Any further details a bonus..For the 'G' series, I'm really missing not having the ability to use the extra pins, including the TRACE when prototyping on my J-TRACE.I know there is the eval kit, but they are not really practical for prototyping or 'hooking into' my projects.I understand it will need an upgraded STLINK device and the STM32G series micro pin-out is different from the STM32F series..Many thanks Thanks.

Is the STM32L451CCU6 a Boundary scan device. I have found other STM32L451 processors BSDL files but cannot find one for this model.

Hi all , we have designed a custom board based on the ST25DV SMARTAG1 reference design with a 18.5cm *22.5 cm antenna as ST25DV-DISCOVERY-ANT-C1 . Our product is batteryless so we need to power it entirely by energy harvesting output.Before making our custom board we tested on smarttag1 board , we have made a simple change in the provided firmware code for smarttag1 and added this line  SMARTAG1_NFCTAG_WriteEHMode(SMARTAG1_NFCTAG_INSTANCE, 0x00);after HWInitialization();We got the expected behaviour and whenever we placed it near a android phone with nfc , we got the voltage from the energy harvesting pin between 3.3 to 3.6v .But on our custom board when we install the same firmware, the ST android app detects the tag but we get the voltage output from the energy harvesting pin as only 0.1 to 0.3 volts . Can you please help us with this problem ? is this because of the antenna size ? Hope my question is clear . thanks for your time

Any one who has successfully drive the eval board with Arduino via spi?I am trying to drive the ST25RU3993 Eval board using SPI, with my Arduino Due (i read an earlier post on that ran at different voltage and solve using 3V arduino board, in my case both devices run on 3.3V) to prototype a quick project. I use the oscilloscope and it seems my spi outputs (sclk, mosi, chipselect, enable) are looking good. However my ST25 board is not responding any useful feedback. Any clue?my wire up is as follow: MISO to MISO, MOSI to MOSI, SCLK to SCLK , pin 2 to EN, pin 52 to NCS.here is my Arduino code:#include <SPI.h> //////////////////////////////////////////// //set up pins for arudino due //MOSI:ICSP-4 //MISO:ICSP-1 //SCK:ICSP-3 //NCS:52 //en:2 // ///////////////////////////////////////////////   const int NCS = 52;   // set up the speed, data order and data mode SPISettings settingsA(5000000, MSBFIRST, SPI_MODE1);   void setup() {   pinMode (NCS, OUTPUT); pinMode(2

Hello, I am preparing a keypad project in touchgfx. Basically I need to print integer and fraction values on LCD screen through keypad. However, since touchgfx generates a wildcard as uint16_t, I am not able to put the value inside a buffer and giving it in the string form to snprintf, so as to print it on the screen. How can I generate a wildcard variable in char* format, instead of uint16_t format?

Hi,How to display strings in TouchGFX which is not defined previously in GUI

Hi ,I try to put IAP Driver in my projects. But, I have a problem with this driver. Let me inform you what I have done and what I have. I use STM32CubeIDE with STM32L071 Controller. I search the IAP Driver. Found one. Download the driver. Put the driver into my src and inc folder. Try to compile. Then, I get error because the driver is used by STM32F4 Series and the driver use Standard Peripheral Library.Considering that STM32CubeIDE generate HAL Library, so I need your help to translate this part of code from Standard Library into HAL Library or their equivalent.FLASH_EraseSector(i, VoltageRange_3) != FLASH_COMPLETE   FLASH_Status FLASH_EraseSector(uint32_t FLASH_Sector, uint8_t VoltageRange)   (FLASH_OB_GetWRP() >> (UserStartSector/8)) == (0xFFF >> (UserStartSector/8))   FLASH_OB_WRPConfig(UserWrpSectors, DISABLE);I really appreciate for your help. thanks.Pradipta

Hello,Has anyone tried updating STM32 firmware over HS USB?I can't remember where I read it, but I remember the default STM32 DFU mode is only compatible with the FS USB.My device is a "USB Device" and it only needs HS USB to do the job, FS is not really required.So I'm looking for ways to implement DFU mode with the HS USB connection.I searched everywhere for the FS or HS connection DFU mode, but I'm only seeing how to use DFU mode not what USB type to use.

Hello,​I'm using STM32F302R8T6. I generated the code by CubeMX and using IAR compiler.At first, TIM1,2 is working well. But TIM15,16,17 is not working.So, I tried to access direct the register as next code.​while (1){ TIM1->CR1 = 0xffff; TIM2->CR1 = 0xffff; TIM15->CR1 = 0xffff; //(*(volatile unsigned *)0x40014000) = 0xffff; printf("TIM1:%X,TIM2:%X,TIM15:%X\r\n",TIM1->CR1,TIM2->CR1,TIM15->CR1); HAL_Delay(100);}​The result of above in serial terminal is attached picture."TIM1:BEF,TIM2:BEF,TIM15:0"​(TIM1 & 2 was changed by code but TIM15 is always zero)In my attempt, no method worked.Please help me.​  ​​

Hi everybody,I'm working on 10 stepper motors controller using STM32F407vgt6. Is there any way how to automatically turn off the step pulse after I turn it on programatically? Maybe something with timer(s)? Some turn off delay? The pulse should be turned off after a defined period of time/clock pulses.The reason why I'm trying to do this is, that stepper motor driver requires some time to sense the pulse and so I can't turn it ON and then OFF immediately.Thank you.

I'm thinking of using PB8 CAN1_RD and PB9 CAN1_TD on STM32L476 . And I don't think we can map them to other pins, is that right?

Hi, I'm using the converter Viper06 in my power supply board project. I'm having some difficulties to design the compensation network of the error amplifier. Could someone please tell me how to do this o share some documents that explains how to design the compensation network.I got some values with the online tool, but I would like to understand how these valuee come out!Thanks.Fab

Hello,i have been trying to put the st25r3916 in wake-up mode but i detect high power consumptions (around 900 uA). I am using a very basic code just to test current consumtion, i2c communication seems to work, but maybe i am missing some parts.int main(){ rfalAnalogConfigInitialize();   if(rfalInitialize() != ERR_NONE) {   } else { rfalWakeUpModeStart(NULL); } }Am i missing some api calls?Thanks,Regards

Hi,is there any plans to add support for MAC OSX to TouchGFX as all other ST tools seem to be multi platform? It would be greatly appreciated :smiling_face_with_smiling_eyes: Kind Regards,Steinar

Hello, I am having problem sendind data to PC with USB. I set the USB_OTG_FS to device only mode and activated the VBUS. I selected Class for FS IP to Communication Device Class (Virtual COM Port). When I try to send data with the simple code below, no data is transmitted to PC: while(1) { //TSA_input_voltage = readVoltageValue(ADC_CHANNEL_5); memset(USB_String,0x00,255); StringLength = sprintf(USB_String," USB Voltage in: %d", 5); CDC_Transmit_FS(USB_String,StringLength); // HAL_Delay(1000); }In the debugging window I can see that it gets stuck at :if (hcdc->TxState != 0){ return USBD_BUSY; }So USBD is busy all the time. As a side note: I try to debug it by using an oscilloscope and it is clear that USB is initialized correctly. D+ line is high and D- side is low all the time. But that's all. No transmission occurs..So my question is, what might cause this problem? I believe I am missing some obvious point so I wanted to take opinions. Thanks beforehand.

Hello,I am using ST25R3911 to read ISO15693 tags with the ST example from X-CUBE-NFC5. Everything works fine, now, I would like to read memory of Mifare Ultralight (without encryption). I know that st25 can't read Classic Mifare, but I don't find the code in the library to read blocks of Mifare Ultralight (ISO 14443). Does it exist ?Thanks.
