Hi guys,I am wondering, if there is any “real” benefit in using the HAL over the LL for simple peripherals like GPIO, ADCs or Timers.So far it looked to me like the HAL does not make the user code more compact or readable. Instead, it just gets more bulky and harder to debug since you have to deal with the HAL code as well.Just as an example, look at the two functions which both do the same. They do a blocking ADC conversion on a given channel. In this case, the LL variant is actually shorter.static uint16_t read_adc_chn_LL(uint32_t chn) { LL_ADC_REG_SetSequencerChannels(ADC1, chn); LL_ADC_REG_StartConversion(ADC1); while (LL_ADC_REG_IsConversionOngoing(ADC1)); return LL_ADC_REG_ReadConversionData12(ADC1); } static uint16_t read_adc_chn_HAL(uint32_t chn) { ADC_ChannelConfTypeDef sConfig = {0}; sConfig.Channel = chn; sConfig.Rank = 1; sConfig.SamplingTime = ADC_SAMPLETIME_28CYCLES; HAL_ADC_ConfigChannel(&hadc1, &sConfig); HAL_ADC_Start(&hadc1); HAL_ADC_PollForC

Hi everyone,I'm working on a 320*240 SPI LCD and I need to optimize the memory consumption and the refresh speed on it.At the moment I'm using 4 partial frame buffer of 9.6kB each (with RGB565 16-bit, so 4800 pixels per buffer), but, when I draw an image with dimension 48*45 (2160 pixels) on a already initialized Screen, the touchGFX calls the write on LCD function 3 times:1 - 48*20 pixels2 - 48*20 pixels3 - 48*5   pixelsThere is any way or strategy to draw it in one single transaction? 

Hi,my application is loaded via the bootloader and i sstarted. Two threads are generated and it seems properly generated because one thread is in ready state while the other is in suspended state.Systick is used for the ThreadX and TIM6 is used for the HAL-Tick.But the scheduler doesn't start the ready thread.Had somebody a similar problem? Can it be a priority problem of the timers?

Hi, could you provide :the TJmax (maximum Junction Temperature), RJA(Junction to Ambient Thermal Resistance), Rjc (Junction to Case) and Rjb (Junction to Board) for the M24128-BFMC6 EEPROM.Thanks

Dear Sir/Madam,Is it possible to have a STM32 with build in UCPD-controller to deliver 240W at the port? or does anyone have experience with this type of application?According to (link: https://www.st.com/content/st_com/en/ecosystems/stm32-usb-c.html?ecmp=tt21056_gl_link_may2021) I should be able to negotiate of up to 240W with EPR (extended power range) if I make use of the STM32G0 series. After consulting your presentation (link: https://www.st.com/resource/en/product_presentation/stm32-usb-c-pd-solutions-presentation.pdf) I have come to the knowledge (see page 10) that I also need a TCCP0X port protection IC, I want to have a STM that is able to sink or source power (DRP) according to the presentation I need a TCPP03-M20. Consulting the datasheet of the TCCP03-20 I came to the conclusion that it complies with powers up to 100W only. Also looking into AN5225 (https://www.st.com/resource/en/application_note/dm00536349-usb-type-c-power-delivery-using-stm32

 Hello, I am trying to use AES-GCM from the STM32 cryptographic library V4.2.0 to encrypt data.When running the example program, encryption and decryption work smoothly.However, when I integrate the library and function into my existing program, the encrypted ciphertext differs from expected_ciphertext.Additionally, using this incorrect ciphertext and incorrect tag still decrypts to the correct plaintext.Could you please advise where the error might be causing this result?  const uint8_t Key[] = { 0x46, 0x3b, 0x41, 0x29, 0x11, 0x76, 0x7d, 0x57, 0xa0, 0xb3, 0x39, 0x69, 0xe6, 0x74, 0xff, 0xe7, 0x84, 0x5d, 0x31, 0x3b, 0x88, 0xc6, 0xfe, 0x31, 0x2f, 0x3d, 0x72, 0x4b, 0xe6, 0x8e, 0x1f, 0xca }; const uint8_t IV[] = { 0x61, 0x1c, 0xe6, 0xf9, 0xa6, 0x88, 0x07, 0x50, 0xde, 0x7d, 0xa6, 0xcb }; const uint8_t Plaintext[] = { 0xe7, 0xd1, 0xdc, 0xf6, 0x68, 0xe2, 0x87, 0x68, 0x61, 0x94, 0x0e, 0x01, 0x2f, 0xe5, 0x2a, 0x98, 0xda, 0xcb, 0xd7, 0x8a, 0xb6, 0x3c, 0x08, 0x84, 0x2c, 0

Hi, In one of my designs, I used the L6981 5.0v low-noise variant. I followed the datasheet, and this was my first time using this chip. However, I added an option that separates the AGND and PGND pins with a ferrite bead which is not present in the datasheet. As shown in the schematic with a red arrow below:When this ferrite bead is present on the circuit, the L6981 fails to boot properly. Thus gave 2.5v output with a strange signal shape (below).  When I short the ferrite bead, it seems like the L6981 is working properly.  I wanted to filter 24v supply ground with 5v ground. But as it seems the way that I do is possibly wrong. Why is the ferrite bead causing that effect? Thank you in advance. 

I am  using my own custom board which is replicate of stm32f429 disc1 development board. I replaced main mcu chip i.e stm32f429 and stlink chip from my disc1 board to my custom board. After using my custom board for for many days now it stopped working. The board is getting heated and st-link not detected error is getting popped one i connect usb power supply. I unable to find the reason for its failure.I have attached my custom board schematic. Now I want make another custom board with external debugger what changes I have to make in the schematic to make my board work like disc1 board.

I am trying to make an API for W25N01 flash. I have seen many post about this flash board and followed them. But they have not solved the problem of me not being able to read the data (so either my write function or read function is incorrect). The weird behavior which I am facing is.when I dont call the `loadBuffer` and the `programExecute` function. I can read and write fine, but I cannot write and read other pages.

Hi all I would like to know if I can use the CDC example to transmit and receive data from the windows host without redirecting it to UART

I have tried to build my own OpenSTLinux by using the SDK and the sources, without sucess. I have been trying to compile for 2 weeks from now and I'm not very pleased over the wiki of ST32MP.Anyway. I have to show a bug. I cannot build an OpenSTLinux Project inside STM32CubeIDE.I first created a project for my STM32MP1 processor, then I tried to attach the SDK with the STM32CubeIDE. But it did not work well.I have STM32CubeIDE 1.16.0 and Lubuntu 22.04 and the latest SDK. So what I'm looking for, is some way to compile the kernel, TF-A, Optee and U-boot with STM32CubeIDE. If it's possible. Or else....it's impossible to follow the wiki of STM32MP. How to install the Yocto Project SDK in STM32CubeIDE - stm32mpuThis is my goal: How to manage OpenSTLinux projects in STM32CubeIDE - stm32mpu 

What is the default timer clock frequency of the APBx buses on an STM32F410RB? I've been considering it to be 16MHz to calculate the frequency of my PWM wave, but it turns out I get half the frequency on scope (is the default clock at 8MHz for timers? I have not altered clocks, and I'm using TIM5_CH1).

I am trying to connect two VL53L8CX time of flight sensors to STM32F401RET6. I need one I2C bus for both sensors but unable to assign slave address dynamically. I need to know where to modify the program in stm32cube IDE

Hello,My first time posting on this forum so apologies in advance. I am working with an LCD screen that will have multiple menu's so I designed this struct with multiple pointers.

Hello,I followed the instructions provided in the UM2851 to run the TFM application contained in the latest STM32CubeU5 1.6.0 Firmware projects folder, but the application does not run, it enters an infinite loop instead.Any help please?@Jocelyn RICARD @Guillaume K 

I have an STM32L433 that implements a SPI slave, it is connected to another MCU master. It is unclear from the datasheet and searches for answers whether MISO and MOSI on the slave should connect directly to MISO and MOSI on the master, or, if they should be crossed. Is master MOSI -> slave MOSI and master MISO to slave MISO correct?Sid

Hi,I have just opened my new STEVAL-PROTEUS1 evaluation kit for my project. I tried to connect it with the STBLE sensor app, but I realized that it does not appear on the Bluetooth search. Then I tried my STEVAL-STWINKT1B sensor kit, and it connected, so I assume that the issue is not related to the cable. Do you have any solution for this problem? I would appreciate it very much if you could help with this.

Noob here.  Using HAL and as much generated code as possible.   Ive run into an issue on how to self learn,  I've identified what I believe is the solution but nowhere( that I can figure out) in the reference document does it point to this in what I believe would be obviously described. I have a situation where I am in need of using an MCU to simulate a quadrature encoder and some other inputs to a larger system for testing.   The encoder goes from rest to 132kHz and back to rest 13 times a second.  My first attempt was to use PWM/DMA and phase shifting but it kinda fell apart on me maintaining the phase shifts.  I watched some videos and it occured to me that I could DMA a cyclic buffer through the GPIO without trying to maintain phase shift by writing directly to the GPIO:      uint32_t enc_cycle[4]; for(int i=0; i<4 ;i++) enc_cycle[i]=0; enc_cycle[0] = 0x00000001; enc_cycle[1] = 0x00000002; enc_cycle[2] = 0x00010000; enc_

Hi all,I'm working on a product that uses a TOF sensor (exact type# TBD) to identify if someone(s face) who is sitting in a chair is present within a certain distance and angle (around 20 degrees). If the right conditions are met the product should be switched on. I'm looking for ways to prevent the product from switching on based on false positives that the sensor receives from static objects when no on is actually present, such as wall, chairs etc. Appreciate your thoughts! 

I am working to create a GUI and am trying to generate code, however, each time I do, I get an error that "The system cannot find the file specified." as TouchGFX tries to generate assets. A colleague of mine has generated the code on his system and it was able to generate all the code. I have tried uninstalling and reinstalling TouchGFX, yet that did not solve the issue, and would love guidance on how to fix this problem.

Dear ST-Developer,i have discovered that the ADC configuration with cube takes only effect for one channel instead of every enabled channel. In the reference Manual and HAL_ADC documentation i have understood that each ADC-Channel of the G474 series are independent configurable from each other.  The problem is that the generated code by CubeMX seems to not generate the configuration for enabled channels.I have expected that ALL  ADC-Configuration for ALL enabled channels will be generated. So i faced the problem that only one ADC-Channel (independent from ADC1,2,3,4 and 5) was configured correctly.I don't want to check the code generated by CubeMX for correctness because then i can write it by my own from scratch. And i don't want to insert missing channel configuration by hand because i use CubeMX that should do it for me. Thats why we use it to simplify our work. Our code uses the Hardware configurations from CubeMX as single point of truth  so that we have only t

Currently using a STM32L4R9I-DISCO and I've been struggling to get the SWV ITNM Data Console to work so I can do some debugging. I'm quite new to this, but I've followed every tutorial online to enable UART and how to set it all up, to no avail. I've managed to get the Trace Log to work, but I am looking for values of the variables in loops as the code is executed. Is there any other way to do this or is someone capable of helping me set this up?

HI,I cannot delete page 15, or other pages, of the STM32C031K6T6 flash chip. HAL_StatusTypeDef status; EraseInitStruct.TypeErase=FLASH_TYPEERASE_PAGES; EraseInitStruct.NbPages=1; EraseInitStruct.Page=15; status = HAL_FLASH_Unlock(); status = HAL_FLASHEx_Erase (&EraseInitStruct, &PageError); status = HAL_FLASH_Lock(); Where am I wrong? Can someone help me?Thanks everyone in advance.   

Hello,Is it possible to drive two independent LCD screens from one e.g. STM32MP157? I know it has LTDC controller and also is having MIPI® DSI but I was wondering if it can run them together (no overlapping pins)?I want  to make a product that will have one display (non touch), maybe for video output 720p - non touch; and one smaller screen 480p with touch to serve as digital buttons.
