Solved

I have gone through the methods that are gui generated when change screen transition is done through the designer. I have also gone through the previously asked question how to implement switchscreen() in touchgfx. However, sadly I don't understand exactly how to fulfill my requirement. I want to carry out transition whenever a certain boolean variable becomes true. The variable becomes true after response from the hardware. Please guide me on how to implement this. I shall be thankful.

I'm trying to use X-NUCLEO-NFC01A1 with STM32 F429ZI to read data from phone NFC. When I'm trying to open session HAL_I2C_Master_Transmit(&hi2c1, M24SR_ADDR, (uint8_t*)pBuffer,NbByte, 1)in function M24SR_SendI2Ccommand (file drv_I2C_M24SR.c) returns HAL_ERROR. Any ideas why?Thank you for your help.

Hi all,I am trying to create simple makefile project in CubeMX for stm32g431. After executing makefile I get error:/home/pawel/STM32Cube/Repository/STM32Cube_FW_G4_V1.1.0/Drivers/CMSIS/Include/cmsis_gcc.h: In function '__get_CONTROL': /home/pawel/STM32Cube/Repository/STM32Cube_FW_G4_V1.1.0/Drivers/CMSIS/Include/cmsis_gcc.h:152:1: sorry, unimplemented: Thumb-1 hard-float VFP ABI { ^I suspect it has something to do with this:# float-abiFLOAT-ABI = -mfloat-abi=hardIs it something to do with compiler? At the moment I am using gcc-arm-none-eabi-7-2017-q4-major .I have to mention that I didn't have any problems with other sm32f and stm32l.Regards,Pawel

I'd like to turn LED on or off according to UART receiving situation.What I'd like to do is following,1. If there is no receiving during 3 sec from last data, the LED is turned on (showing NO RECEIVING).2. When UART RX interrupt comes, the LED is turned off (showing RECEIVING) .I tried following code, but sometimes the LED turned on during receiving with 1 Hz rate  (one byte comes each 1 sec).// UART RX interruption (UART is 460800bps)void HAL_UART_RxCpltCallback(UART_HandleTypeDef *UartHandle){ <...turn LED off...> // I'd like to restart the timer interruption from 0 again. HAL_TIM_Base_Stop_IT(&htim2); HAL_TIM_Base_Start_IT(&htim2);}// htim2 has been set to 3s interval and started.void HAL_TIM_PeriodElapsedCallback(TIM_HandleTypeDef *htim){ HAL_TIM_Base_Stop_IT(&htim2); <...turn LED on...>}I tried it with both of TIM2 or TIM4. The results were same.I think I should reset something when restart (stop and start) the timer intur

Hello.....I want to know about the swiping .Basically i want to implement my own swipe for that i want to know at what place your handling the swipe control and how...i hope you will help me.I am currently working on STM32L4R9AI-eval.Thank you....

I'd like to use the system DFU on the L476 but Windows says "Device Descriptor Request Failed"Connect ST-Link USB for powerJumper CN7 VDD to Boot0Connect PA11 to white D-Connect PA12 to Green D+Connect USB GNDSB31 is in so Vusb has VDD already. Press Reset buttonNote this Nucleo model lacks an HSE, so the 48 MHz has to come from MSI which is supposed to be automatically trimmed to LSE on this MCU. So my expectation is that this should work. Am I missing something?

Hi,I've been wondering, what would be the quickest way to shift a rectangle of any size that is already on screen, and therefore in the current frambuffer one pixel column to the left, and then delete (turn white or something) the leftmost column?So far I've found the functions copyFBRegiontoMemory and BlitCopy, but that would require to load everything and then write it again to the framebuffer. Using DMA there should be another way, which doesn't involve loading everything but simply shifting.

Hi all,I am trying to configure my stm32f429i-disc1 with the lates CubeMX 5.5 and TouchGfx 4.13. I have followed the instructions from here: https://touchgfx.zendesk.com/hc/en-us/articles/360010921760-TouchGFX-HAL-Development, but my display is still all white (there should be red background with simple 'hello world' string on it).The project compiles and there is also 1s_cnt which increments properly. I've tried to debug the project and noticed that program enters inside functions: void StartScreenPresenter::activate() void StartScreenView::setupScreen()on startup but only once.Both the board and the cable are ok, because I can flash MCU with other project and then screen works fine.Have you got any ideas what I am doing wrong?

Hi,I have a problem with STM32CubeIDE 1.2.0 and TouchGFX 4.13.0.I use the STM32F746G-DISCO board. First, I created a project with TouchGFX to check if the screen works. It works well !After that, I created a project with CubeIDE. I configured the pinout manually and I was able to display an image on the board via a .h file.When I add TouchGFX Generator in "Additional Software", it creates the TouchGFX folder. I changed the .touchgfx file but the screen still black when I launch the project on the target.Could you help me please ?It is very important.

Hello Everybody,I am wondering if this is good code when using an embedded system or if I should avoid adding a LF to an unkown string like I do it here, since this could overwerite other data in the following address:void USART_transmit_message(volatile uint8_t *message) { if(!strchr(message, '\n')) strcat(message,"\n");   strncpy(USARTBufferTX, message, sizeof(USARTBufferTX));   if(huart1.gState == HAL_UART_STATE_READY) { if(HAL_UART_Transmit_DMA(&huart1, &USARTBufferTX, strlen(message))!= HAL_OK) { Error_Handler(); } }   }best regardsBenjamin

Not a question but a statement. I've just upgraded a very large project from HAL V1.3 to V 1.6. The code uses sprintf in a couple of places. This worked fine under 1.3 using newlib_nano. Under 1.6 the same statement gives a NULL return. Swapping to newlib_standard fixes the issue. It appears that the version of newlib_nano distributed under 1.6 has changed and is no longer reliable, at least for floats.

HiSo I''m trying to use the internal temperature sensor to get a rough idea of the temperature. So first I test it on the NUCLEO-F446 and get good result but when I try to use the same code on my board, I get wrong data. Good data is adc value aroud 930 (so 24°C) and wrong value is value around 860 (so 0°C)The nucleo use a STM32F446RET6 and my board a STM32F446RCT6, so basically just the flash size is different. To be sure to have a similar settings I use a 84Mhz clock generate with HSI and PLL.I tried lot of different settings (dma, polling, continuous,...) but it gave all the same resultAny idea why the internal temperature is wrong on my board ?

Hi, I am attempting to receive a large amount of information via fast transfer mailbox on a ST25DV64K chip and and AndroidNFCReader using one mST25DVTag.writeMailboxMessage command, which commands the chip to send data continuously so long as it receives an Ack that the 255 bytes from one message has been read (via .readMailboxMessage). I can successfully receive the first message containing the first 255 bytes, however I am unsure how to advise the chip that the data has been read (i.e. an Ack of sorts) and to send the next block of data. At the moment the output repeats the first 255 bytes when in a while loop with a time delay (as can be seen below), so I am just wondering, if I need to receive more data would anyone be able to advise on the command to use to ensure this happens. Kind Regards,

I have code running on a few thousand units in the field and on the whole they work perfectly, however I'm seeing this problem in a few of the packs and wondered if anyone had seen it themselves or know what causes it or even better what i need to do to stop it occuring. I don't know what causes the problem but at some point the App we have designed is no longer able to access the NDEF record to read its data. When we get the units back and do a restart the problem doesn't go away. The restart process sets the both read and write passwords and enables them and the only failure in this process is that I get  0x69 0x84 ( Reference data not usable) back from the M24SR when trying to enable the read password. The phone cannot read it with the password i have given it, with a password of just 0's or no password so its like the m24sr has got itself into an unknown state. At no point during this entire process is the M24SR power cycled. the code is as follows if(M24SR_Verify( I2C_PW

The scope is showing the following code takes 602ms (I'm using the external crystal, so no jitter) this 2ms can be seen on top of any delay I set.  while (1) { HAL_GPIO_WritePin(GPIOB, profilingPin_Pin, GPIO_PIN_SET); HAL_Delay(300); HAL_GPIO_WritePin(GPIOB, profilingPin_Pin, GPIO_PIN_RESET); HAL_Delay(300); }The toggle of a pin takes 70-80ns so that isn't the issue. I have used the 16MHz clockwhich still has the +2ms, and some jitter as expected.Any insights on this will be greatly appreciated!

I'm trying to create new image with my app, that needs qtwebkitwidgets, but have some problems with that. When bitbake starting compile qtwebkit-my host pc freezes. I read that post https://community.st.com/s/question/0D50X0000AVSWK1SQP/what-is-the-process-for-initializing-the-openembedded-build-environment-stexampleimageqt about qtwebkit, but in my case it doesn't work. My MACHINE=stm32mp1 DISTRO=openstlinux-x11. I tried bitbake with -k and I tried to launch compilation again, first compile stoped at 38%, after rebooting my host-it's 0% and freeze.Is any alternative ideas how I can install qtwebkit to use my app?

Hello,I have a problem,i wrote this program but it dosen't work.It doesn't read its rx pin.Can you help me pls ???

I'd like to know how I can resume receiving data from flow controlled UART.I use HAL, and I set USART2 into "flow control" with Cube MX code like ashuart2.Init.HwFlowCtl = UART_HWCONTROL_RTS_CTS;(115200 bps, data bit 8, stop bit 1, none parity, etc. )I start data receiving as follows,HAL_UART_Receive_DMA(&huart2, &g_recv_char, 1);and the 1 byte receiving is chained as follows.void HAL_UART_RxCpltCallback(UART_HandleTypeDef *UartHandle) {  (......any processes......)  HAL_UART_Receive_DMA(&huart2, &g_recv_char, 1);}It works for a while (10 - 30min), but after it the data receiving is stopped. When I read RDR register with debugger, the value is changed and it is explicit correct data sent from external device.But "HAL_UART_RxCpltCallback" func is not called.When I manually execute "HAL_UART_Receive_DMA(&huart2, &g_recv_char, 1);" (with debugger operation), continuous data receiving is resumed.So I guess the external device is st

Hello, I am experiencing problems with using ADC together with BLE. When I comment out BTLE_StackTick() inside main loop, the ADC reads values correctly (checked over UART). But when BTLE_StackTick() is called, ADC always returns 0.6V. What is the solution?
