Solved

I was setting up pin assignments for a project and encountered a conflict between datasheet and reference manual. Can this be resolved?The datasheet for STM32F103x4 STM32F103x6, filename stm32f103t4.pdf, dated 6/1/2015 9:41:55 AM appears to lack an entry for SPI1_SCK under SPI1_REMAP = 1.According to RM0008 diagram 9.3.10 on page 181/1136, tSPI1_REMAP = 1 should connect SPI1_SCK to PB3.In the datasheet Table 5 on page 28/99, PB3 Remap (right-most column) only includes TIM2_CH2 / PB3/ TRACESWO. PB4 and PB5 do include in the same column SPI1_MISO and SPI1_MOSI, so I suspect the reference manual should prevail.Is there a way to confirm the possible error in the datasheet or otherwise resolve the apparent conflict?Thanks

Hello, I am developing a platform with BLE Beacon connectivity and I am looking to extend the range of our device. Until now, I have been using BLUENRG-M2SA module, which is BLE v5.2 ceritifed. I know that BLE v5.1 >= versions include "long range" mode ( 125 or 500 kbps datarate ), usually described as Coded PHY, but couldn't find any mention of it on M2SA documents. Does BLUENRG-M2SA module support BLE Coded PHY ? If yes, could you point me to a respective document or source file ?

The screen of my H750B-DK board is weirdly flickering every 12 seconds when the system clock is set to 350MHz. Previously I was at 400MHz when the issue first appeared and the flicker happened about every 10 seconds. At 480Mhz (max) the issue seems to be gone.The issue is presented on the video below (for 350MHz):https://youtu.be/M4nj6cP3B6UThe issue appeared randomly after implementing a new feature (a new class containing all MQTT publish message functionality). I have hooked up one class to have access to tick events but there is only one if statement within it with very little code and also it is not run every 12 seconds but rather when a hardware event happens (MQTT disconnection) so this is not it.I am also using tick events in my main screen but there is only an empty placeholder if statement and another if statement for checking a FreeRTOS queue for data (for sending error codes from hardware to TouchGFX for display).I am using no custom interrupt or timer routines yet. This is

I'm a little frustrated that there isn't a "Here's ST's Time of Flight sensor offering and which sensors have which features" kind of page. The sensor datasheets themselves also do not give any real comparison data to other (pin compatible) parts.From what I have gathered:vl53l0x - 25o FOV, base model in ranging sensors. Single zone, single targetvl53l1  - 27o FOV, multi-zone (adjustable FoV)vl53l1x - same but with more zones?vl53l1cb - no ideavl53l2 - not a productvl53l3cx - 25o FOV, multi target, faster (1MHz) I2Cvl53l4cd - 18o FOV, short range (1mm - 1300mm), fast (100Hz), 1MHz I2Cvl53l4cx - histogram based (?), long range (0-6000mm), 18o, multi targetLooks like the L5 isn't footprint-compatible:vl53l5cx - 63o FOV, multizone, mutli-targetvl53l5cp - cx + person detect?vl53l8ca - 2nd gen, wide FOV like L5, pin compatible with L5?Then there's the VL6180, which is not footprint compatible and I think is older, based on an earlier ToF design, and the VL6180x which add

Hi,I am trying to find a low power solution for close range (down to 1mm) proximity detection at 1Hz frequency. It seems VL53L4CD can do the job pretty good but I didn't find power consumption details of low power mode in the datasheet.I also found there is a Ultra Low Power driver for VL53L3CX which only consumes ~50uA@1Hz but it doesn't support close-range. Can VL53L4CD achieve something similar wrt power consumption?Thanks!

My goal is to reserve a pin over CubeMX to remind me later to use that pin as an optional GPIO for example.I want some kind of marker that when I come back on the CubeMX configuration it catches my attention. I would prefer a color marker.I don't want to use the regular GPIO input assignation (shown in green on CubeMX) because it is lost among my 100 pins already configured (and also shown in green on CubeMX).Some clues of achieving my goal (but that appears not feasible at the moment on CubeMX v6.4.0):• Assign <Single mapped signals> on a simple GPIO output over CubeMX (pin becomes yellow);• Apply a label on an unused pin (pin stays grey but with option label on it);• Change pin color of a regular GPIO output.One other method without using the color marker could be to use a label marker tag like: <[OPTIONAL] My_Pin_Label>. But this is not a suitable solution for my post.Regards,Nadreoh

Hi ST Member, Is there any specific function pack for "Optical Character Recognition"?. I have a kit STM32H747I-Disco, Planning to do some projects in character recognition. Regards,shankari.

Will there be a Rebuild Button in the future like in TrueStudio?

Below error is throwing in Manjaro Linux when I try to upload the program to the board. The project is building successful. Installed libncurses from AUR as well as the offiicial repository, but no use.

Hi,I am trying to set up two timers so that they generate a PWM with the second timer being 1/4 phase past the first one. I am using an STM32F446.I have the second set up as slave and triggered by the OCREF2 of timer 1, this should then generate a reset of timer 2. Below is my timer init by cube mx and I'll also post the registers.static void MX_TIM1_Init(void) {   /* USER CODE BEGIN TIM1_Init 0 */   /* USER CODE END TIM1_Init 0 */   TIM_ClockConfigTypeDef sClockSourceConfig = {0}; TIM_MasterConfigTypeDef sMasterConfig = {0}; TIM_OC_InitTypeDef sConfigOC = {0}; TIM_BreakDeadTimeConfigTypeDef sBreakDeadTimeConfig = {0};   /* USER CODE BEGIN TIM1_Init 1 */   /* USER CODE END TIM1_Init 1 */ htim1.Instance = TIM1; htim1.Init.Prescaler = 99; htim1.Init.CounterMode = TIM_COUNTERMODE_UP; htim1.Init.Period = 63999; htim1.Init.ClockDivision = TIM_CLOCKDIVISION_DIV1; htim1.Init.RepetitionCounter = 0; htim1.Init.AutoReloadPreload = TIM_AUTORELOAD_PRELOAD_DI

Dear Sir,I'm new to STM32WB55 and using STM32CubeMonitor-RF.We see the value of RAW RSSI from the Value parameter of Command Complete of ACI_HAL_READ_RAW_RSSI in STM32CubeMonitor-RF and it results in the RSSI dBm.Such as:(RAW RSSI) --> (RSSI dBm)0x000006 --> -107.00 dBm0x000007 --> -107.00 dBm0x00000A --> -106 dBm0x00000B --> -105.00 dBm0x000012 --> -103.00 dBm0x000014 --> -102.00 dBm0x000017 --> -100.00 dBm0x00001C --> -98.00 dBm0x00001D --> -98.00 dBm0x000021 --> -97.00 dBm0x000024 --> -97.00 dBm0x000029 --> -96.00 dBm...0x0001A9 --> -75.00 dBmMay we ask you about the formula for converting RAW RSSI value in dBm? Thank you.Sincerely yours, David 

Hi there,I am using an STM32WLE and putting it into Standby mode for extended periods of time. I am trying to retain SRAM2 while in Standby mode, and it is working while the DBGMCU_CR_DBG_STANDBY bit is set. However, when I clear the bit SRAM2 is no longer retained.I have set the PWR_CR3_RRS bit, the option byte SRAM_RST is set by default, and I have set my linker to not initialise the portion of SRAM2 that I wish to retain.Does anyone have any ideas as to why debug mode could have such an impact on RAM retention?Thanks,Rebecca

Hi,We are currently evaluating STEVAL-MKI160V1 with STEVAL-MKI109V3.There is a Bluetooth module connection in the schematics of STEVAL-MKI109V3. Are there any documentations about that Bluetooth support? Can it be used to wirelessly stream out the sensor data to a PC?Our test setup involves a moving machinery and for safety reasons, we need to be at a distance from it.Are there available options for wireless transmission of data from the eval board?

The STM32F767.svd file is provided by the STM32CudeIDE, within the com.st.stm32cube.ide.mcu.productdb.debug_1.5.0.202011051456 directory. The two forgotten definitions are :field CAN3EN in the RCC_APB1ENR register;field CAN3RST in the RCC_APB1RSTR register.Best Regards,Pierre Molinaro

I want to test the power supply without Vsmps. So, I have to connect the VDD to the Vlxsmps, Vfbsmps in the Nucleo-68 board.Fortunately, the Nucleo-68 board already has a current path called SB31 but there is an extra description "FW configuration needed" looks like below. Here is my question.What's the FW configuration and How to change it in this board?

I found that the STM32WB55 microcontroller have SMPS but I cannot understand how much external component is required.Here is basic SMPS circut and could you tell me how much circuit is in the microcontrollers SMPS?

BQ_GE_GPIO_Port->MODER = GPIO_MODE_ANALOG;//setting to analog to save powerThis seems to not work at all. I have a physical pulldown on the pin but the pin stays HIGH. Why is that?i init the pin via this code here:__HAL_RCC_GPIOB_CLK_ENABLE(); GPIO_InitTypeDef GPIO_InitStruct = { 0 };   /*Configure GPIO pin */ GPIO_InitStruct.Pin = BQ_GE_Pin; GPIO_InitStruct.Mode = GPIO_MODE_OUTPUT_PP; GPIO_InitStruct.Pull = GPIO_NOPULL; GPIO_InitStruct.Speed = GPIO_SPEED_FREQ_LOW; HAL_GPIO_Init(BQ_GE_GPIO_Port, &GPIO_InitStruct); my understanding is that i can jsut switch between the modes to save power when going into sleep. And that when its in Analog mode that it will not use any pullup internally. i have apulldown externally on the pin with 400k ohm.
