STM32H735G-DK has a number of projects as deliverables examples(ADC, LED,DMA,RTC,...).Are there some rules or tutorials for join two projects as single one project?(From two main.c => one single main .c and what else should have to do ?) in StmCubeIDE?

I use to develop with IAR.I try to go to STM32CubeIDE.I cannot find the way to stepping debug a program if an interrupt timer is running in background.Is there an option like IAR "disable interrupts when stepping"Thanks

In the example while(HAL_I2C_Master_Transmit_DMA(&I2cHandle, (uint16_t)I2C_ADDRESS, (uint8_t*)aTxBuffer, TXBUFFERSIZE)!= HAL_OK) { /* Error_Handler() function is called when Timeout error occurs. When Acknowledge failure occurs (Slave don't acknowledge its address) Master restarts communication */ if (HAL_I2C_GetError(&I2cHandle) != HAL_I2C_ERROR_AF) { Error_Handler(); } }I want to know why if (HAL_I2C_GetError(&I2cHandle) != HAL_I2C_ERROR_AF) here rather than  if (HAL_I2C_GetError(&I2cHandle) == HAL_I2C_ERROR_AF) if I want to judge Acknowledge failure thanks

Hello guys , i am supposed to construct a square wave with automatic toggling making use of the output compare channel one setting. the channel one of the timer is in pin PA6 Does anyone know if this is also the pin were the output (final waveform) will be shown? or must i introduce another GPIO pin to connecte it to this PA6 somehow? ANY HELP IS APPRECIATED!!

Hi! I'm working with the LORA E5 trying to make a small librarie to easily send/receive data through LORA protocol (Not lorawan). The given examples (Ping-Pong) use the task scheduler and the Subghy app, wich im not planning on using. My question is: What do I have to enable in cubemx to make it work in it's minimum form (using radio.c)?I've merged all the files that i think are important in one single file, now the problem is how to initialize all the hardware. Do you have any info about that or know where to find info about it?Thank you very much.Have a nice day.

Hi,I can test the Active tamper to triger erase backup register and SRAM2 data, but don't know how to test "temperature, voltage and frequency attacks" to triger erase backup register and SRAM2 data.Please advise,Thanks,QiZhang

The LSP27HHW also embeds a temperature sensor. Comparing the datasheet, I can´t find any diference. Why LPS27HHTW is 1€ more expensive?

Hi all,I want to use TouchGFX to manage a simple display with STM32L476. I generate the code with cubeMX and TouchGFX 4.16, but when I try to compile it a lot of errors comes up!There is any tutorial or guide on how setup touchGFX with this microcontroller?ThanksBest regardsMarco

I have been experimenting with animating an image onto the screen. Because I want to reduce the amount of FLASH space required, I would like to use an L8 image (I do appreciate adding this format to the TouchGFX framework, by the way).I am placing the image in a container and I have selected the MoveAnimator Mixin for that container. However, I notice that the amount of time it takes to animate this container from off the screen to on the screen takes significantly longer when the image is formatted as an L8 (either L8_RGB565 or L8_ARGB888). When I say significant, I am saying it takes up to 50mS as compared to 12mS.Am I doing something wrong? Is it possible that the DMA2D (ChromART) not working correctly for L8's?I am using TouchGFX 4.13.0 and my processor is an Stm32H743.

When you create a project, CORE_CM4 symbol is added to properties by default.However, if you look at stm32mp1xx_hal_rcc.h, the CORE_CM4 area is still disabled. Is it a bug? Can I ignore it and use it? Or please tell me how to solve it.

Hi, I have a question the difference of waking up between LOW_POWER_SLEEP_MODE and STOP_MODE.I have used ADC for waking up from STOP_MODE and LOW_POWER_SLEEP_MODE respectively.According to STM32L051U6 datasheet, both modes cannot be waken up by ADC, however, in LOW_POWER_SLEEP_MODE, it seems that ADC works as wake-up. Is there anything that I misunderstood? How is it possible to wake up LOW_POWER_SLEEP_MODE by ADC?I attached snapshots of the datasheet about waking up just in case.Thank you in advance.the datasheet for wake-upEntering Stop/low-power-sleep mode/* Enable Ultra low power mode */ HAL_PWREx_EnableUltraLowPower();   /* Enable the fast wake up from Ultra low power mode */ HAL_PWREx_EnableFastWakeUp();   /* Select HSI as system clock source after Wake Up from Stop mode */ __HAL_RCC_WAKEUPSTOP_CLK_CONFIG(RCC_STOP_WAKEUPCLOCK_HSI);   /* enter stop mode */ HAL_PWR_EnterSTOPMode(PWR_LOWPOWERREGULATOR_ON, PWR_STOPENTRY_WFI);   /* enter low-power-sleep mode HAL_P

What are the power levels for the different settings when calling aci_hal_set_tx_power_level()? All I can find for sure is a max power level of +8 dBm in the datasheet. Other tables I find in the BlueNRG-1_2 DK documentation give conflicting answers and none mention the En_High_Power parameter.This question was asked before here: https://community.st.com/s/question/0D50X00009XkfpySAB/which-parameters-are-suitable-for-acihalsettxpowerlevel-with-spbtlerf-but for a different chip. I'd like to know the answer for BlueNRG-2.

My project involves a Nucleo-64+X-NUCLEO-BNRG2A1 communicating with an Android phone via Bluetooth.I successfully sent data from the server (BNRG2A1) to the client (Android phone), but I cannot figure out how to do the same from client to server. Under Android, I can write data to the characteristic (in NO RESPONSE mode), but I fail to understand how to handle the write operation server-side.My characteristic is declared as follow:ret = aci_gatt_add_char(HWServW2STHandle, UUID_TYPE_128, &char_uuid, 2+2+4, CHAR_PROP_NOTIFY|CHAR_PROP_READ|CHAR_PROP_WRITE_WITHOUT_RESP, ATTR_PERMISSION_NONE, GATT_NOTIFY_READ_REQ_AND_WAIT_FOR_APPL_RESP|GATT_NOTIFY_ATTRIBUTE_WRITE, 16, 1, &EnvironmentalCharHandle);What is it supposed to happen server-side? I've tried to implement aci_gatt_write_permit_req_event(), aci_att_exec_write_resp_event() and aci_gatt_indication_event(), but they are never called. Also, nothing is displayed in the console (with full debug info) when w

version: touchGFX Designer 4.16.1I generated a ScrollList to contain 8 itemsIn the .touchGFX project (attached) I can see the expected lines"Type": "ScrollList", "PaddingBefore": 0, "PaddingAfter": 0, "Snapping": false, "IsHorizontal": false, "IsCircular": false, "ItemTemplateName": "lightSliderGroup", "NumberofItems": 8,However in the base class of the generated code I see this:touchgfx::ScrollList lightGroupList; touchgfx::DrawableListItems<lightSliderGroup, 6> lightGroupListListItems;The odd thing is that 8 items actually got created, however in my case the slider value of the last 2 items always follow the value of the first 2 items in the list?Hacking that line to change it from 6 to 8 does not fix the issue either.Am I missing something or is this a bug? If so, is there any workaround?

I would like to know how we can configure STM32H7's SAI(s) for 8-PDM microphone inputs (LR * 4 pairs). (16kHz sampling rate).It seems MX allows us 6 mic with SAI1 and 2 mics with SAI4 but I'm not sure how we can set SAI1/4 exactliy for 8 mics (synchronized data acquisition I want)

hi dear.​I have some problems with the Flash bank configure.​STM32F767 is used by setting Flash Bank to Single or Dual.​So I want to set Dual Bank Mode on Flash Memory.​However, the Dual Bank setting does not work properly.​ ​I changed the Option bytes to set Single or Dual Bank.​Below is the code I wrote.​​bool flash_opt_init_func(void) { uint32_t ret = true;   FLASH_OBProgramInitTypeDef ob_bytes;   HAL_FLASHEx_OBGetConfig(&ob_bytes);   if(ob_bytes.USERConfig & OB_NDBANK_SINGLE_BANK) { HAL_FLASH_OB_Unlock();   ob_bytes.OptionType = OPTIONBYTE_USER | OPTIONBYTE_RDP; ob_bytes.USERConfig = OB_NDBANK_DUAL_BANK | OB_DUAL_BOOT_DISABLE | OB_IWDG_SW | OB_STOP_NO_RST | OB_STDBY_NO_RST | OB_IWDG_STOP_ACTIVE | OB_IWDG_STDBY_ACTIVE | OB_WWDG_SW; ob_bytes.RDPLevel = OB_RDP_LEVEL_0;   HAL_FLASHEx_OBProgram(&ob_bytes);   if(HAL_FLASH_OB_Launch() != HAL_OK) { return HAL_ERROR; } HAL_FLASH_OB_Lock(); } else return ret;

Hello,I am trying to generate white noise using the DAC, much like was mentioned in this forum post:How to generate a white noise with the DAC on STM32L1However, I don't know if putting values into memory table and using cyclic mode is the only answer. From my research using Audio and waveform generation using the DAC in STM32 microcontrollers - Application note, it looks like you should be able to use the LFSR (Linear Feedback Shift Register) / Random Number Generator in Figure 5 to make white noise as is shown in Figure 6 on page 9: Here is how I have my STMCubeMX set:And here is my "Software Trigger": HAL_DAC_Start(&hdac, DAC1_CHANNEL_1); HAL_DAC_Start(&hdac, DAC1_CHANNEL_2);Yet, when I look at the oscilloscope, all I get is a DC offset just like my friend in the other forum post observed: Any thoughts on this? Many thanks in advance!

Hello all,I have STM32F439 MCU.I use STM32CubeProgrammer to program the MCU through ST Bootloader.STM32CubeProgrammer writes:Bootloader protocol version: 3.1According to AN2606 (STM32 microcontroller system memory boot mode) the valid version for STM32F42xxx/43xxx are: V7.0 or V9.0 or V9.1.Can you please advise why the reported version of Bootloader is 3.1?Thanks in advance.Yacob.
