Hello,I am in the process of making my own circuit board and using an f767 with 144 pins. I have integrated a QSPI and a 40-pin FPC for an 800x480px display. The LTDC is in RGB565. Unfortunately, I don't have any pins left for the SDRAM. So the question is, do I need the SDRAM? Can the QSPI replace it?

I am working with STM32L010C6T6 MCUs. I need a way to consistently and uniquely identify each MCU with as few bytes as possible. The 96 bits "Unique device ID" register seems ideal but what is the minimal number of bytes I need? Are all 96 bits mandatory to fulfil my needs? At a first look, the answer seems to be no as 4 bytes seems to be enough but I am not sure.In Reference Manual RM0451, section 25.2, page 730-731 the 96 bits "Unique device ID registers" are described as follows:[23-0]: LOT_NUM in ASCII code[31-24]: WAF_NUM in 8 bits unsigned number[63-32]: LOT_NUM in ASCII code[95-64] Unique ID bitsHere are my assumptions. We have 3 distinct fields:LOT_NUM: An ASCII string represented by 56 bits => 7 chars/bytes. I assume that only the 7 LSB bits of each byte are significant (standard ASCII code represented on 7 bits) and this string may be common among MCUs of the same Lot.WAF_NUM: A Wafer number represented by 8 bits => 1 byte. I assume that all bits are significant and thi

HelloI am trying to implement low power mode with STM32WLE5 MCU (as a part of RAK3172-SIP).However, the current consumption is unreasonably high.I measure around 200uA with 3.6V and around 150uA with 3.3V.Did many tests with different configurations, checked the RF switches. I use TXCO, but even if I run with internal clock - no changes. Debug mode is disabled.How can I debug it further?I even tried to go into Stop2 mode directly before HAL_Init() - still the same 200uA (at 3.6V) consumption. So even before all periphery is initialized I cannot get the lower consumption.I did similar test with Wio-e5 module just to check that the HW is not an issue, and there I 've got around 300uA (at 3.6V). So I have no questions to HW.Regarding the HW, there I have one 100k resistor to BOOT0 to GND and one 100k pullup to nRST. The rest is caps and inductors for supply lines, nothing else is connected to the module.I was thinking this is because of SMPS - but I checked that it is not running in

The board is set up as follows, and USB of ST-Link V2-1 is connected to Host PC.   when using Linux host pc , /dev/ATM* devices not recognized.So I used a Windows PC, but it is not recognized either.Do I need to install a special driver to recognize the Uart serial?Or is there a problem with the Jumper setting?

Can we connect D1+ to DN and D1- to DP (same for the connector (D1+CON to USB_D_N))

I think there is an error in the PM0214 Programming manual "STM32 Cortex® -M4 MCUs and MPUs programming manual". The multiply and accumulate instruction is called "vlma" throuout the whole document. Other programmin manuals (e.g. for STM32H7) as well as the assembler say this must be "vmla" instead.

Hi!STM32MP1 provides a real-time core, and we use it for the hard-real time. But additionally, we would need the application running on the two fast cores to also be real-time. (with softer constraints but still better than standard scheduling on Linux).For this, I added to the yocto project, at (not the best place, but just trying to make it to work for now):Layers/meta-st/meta-st-openstlinux/conf/distro/openstlinux-weston.confPREFERRED_PROVIDER_virtual/kernel = "linux-yocto-rt" COMPATIBLE_MACHINE = "(stm32mp1)"But then, I get the following errors:ERROR: Nothing PROVIDES 'quilt-native'quilt-native was skipped: incompatible with machine stm32mp1 (not in COMPATIBLE_MACHINE)ERROR: Required build target 'st-image-weston' has no buildable providers.Missing or unbuildable dependency chain was: ['st-image-weston', 'quilt-native']

Hello,We are using ST25R3920 with another host MCU(NXP S32K116) in a project. Our customer want us to be able to update the firmwares of modules in the board via host MCU if a new feature or some problem fixes are needed.So my question is, does ST25R3920 support such feature? If yes, does ST provide the new firmware for the module?I looked through the documents related to ST253920 but could not find any information regarding this issue.Thank you and best regards,Furkan

I am trying to use ST3993 to get distance between tag and the reader.Is there any SDK or function in the ST3993 to do that?

we installed an application binary on NUCLEO-144/F429ZI with UART2 as an external interface and USB-UART for debugger.And the binary code been downloaded via the debugger port using STM32CubeProgramer with the tool option of "STM32CubeProgramer(SWD)" and "USB support(if possible): None"It goes well without readout protection of OB(Option Byte). Also well in serial out on USB-USART.By the way, once Read out protection was set to 'BB' from 'AA', it will not go well. no output on USB-UART.What's my misunderstanding on the Readout protection?

[Solution] Code was moved around and then it compiled correctly. Misinterpretation of the problem.IOC Configuration: Pin PB9 - External Interrupt with Rising/Falling Edge trigger detectionPull-DownNVIC EXTI line [9:5] Enabled Preemption Priority 1 Sub Priority 0Code Changes: Inside Main.c/* USER CODE BEGIN WHILE */void HAL_GPIO_EXTI_Callback(uint16_t GPIO_Pin) { HAL_GPIO_WritePin(GPIOB, GPIO_PIN_11, GPIO_PIN_SET); }To my understanding to accomplish the interrupt with a callback to turn an led on all I need to do is change the state of the pin from high to low or visa versa. Then override the _weak definition of HAL_GPIO_EXTI_Callback.Any advice would be very helpful here but I have tried almost all of the different settings for registering the interrupts without any luck.

I think there is an error in the reference manual (RM0440 Rev 7) in chapter 24.5 - COMP interrupts.At the end of this chapter it says: "Interrupt events are flagged through COMP_CxCSR flags."But in COMP_CxCSR register there is no flag for interrupt event?The Interrupt is handled by EXTI, so the Flags are in the EXTI_PR1/EXTI_PR2 register.Or do I miss something?

I have ST25RU3993s with marking "E". I see a note in rev.11 datasheet mentioned not to used the "E" or "ES" marking for the production board. (1)Is the note still true? (2)If It's released in the field, what kind of failures do I expect?Thanks,-Tieng

Hi Guys,In STM32CubeIDE I start a new project for this board, I leave everything in the ioc unchanged and generate the code.The call to MX_USB_OTG_HS_HCD_Init() works correctly.I now change in the ioc: USB_OTG_HS Internal HS Phy from host_only to device_only and regenerate the code.Now the call to MX_USB_OTG_HS_PCD_Init() ends up in the Error_Handler(), this is caused by a timeout in USB_CoreReset().Does anyone have any ideas why this might be?Many thanksAndy

I'd like to play a FHD video 1920x1080 25 fps on a FHD monitor.There is some hardware codec inside MPU I can use?On other platform (like imx6 I used it own codec h264), but reading datasheet I don'r find anything about codecs video on thi MPU.I suppose MPU has not usable hardare video codec.Thanks all MZ

I made an I2C communication between STM32U585 uC to an I2C EEPROM and it worksI do the following  but if I remove the HAL_Delay(10) or minimizes it to less than 10msec things are not working well, the second call I2C_Master_Transmit fails.Is there's a way to call the I2C_ISR register or anything else, in order to check if the writing process was completed before proceeding with the communication?Thanks!
