I'm trying to do a quick eval of a NUCLEO-G474re board for use of the SoC as a product communication controller (I2C, SPI, RS-485, etc.), initially using the Arduino environment for rapid testing. Initial attempt to bring up I2C causes NO activity on SCL/SDA as observed on a logic analyzer.Relevant code fragments for a DS1683 at 7-bit address 0x6B: #include <Wire.h> Wire.begin(); // SCL/SDA on Arduino D15/D14 (G474 PB8/PB9) Wire.setClock(100000L); // 100 kHz Wire.beginTransmission(0x6B); Wire.write(0x01); // Check the Status register Wire.requestFrom(0x6B, 1); byte RegData = Wire.read(); Wire.endTransmission();Am I missing something obvious? Why is the I2C bus quiet?Thanks!Edit: Downloaded an I2C Scanner sketch. No I2C activity on the NUCLEO, but works on an Arduino Due.-BobC

Hi,I am having trouble configuring the ADC on my STM32L431KB. The calibration procedure appears to go well until it gets to the step where the program waits for the calibration to finish. It is never able to finish. I think the problem may be related to the fact that ADC1_CR_ADEN is always set 1, and I am unable to change it to 0. Does anyone know why this might be happening?Thanks,

I've have a custom board with a STM32G031,from the board we have access to the following MCU pins:+3V3_BTNRSTBTSWDIOSWCLK_USARTTXI've connected this 4 pins to a ST-LINK/V2. Like this (left) mcu, (right) st-link.+3V3_BT --> VCCNRSTBT --> NRSTSWDIO --> SWDIOSWCLK_USARTTX --> SWCLKThe current delivered by PSU goes to almost 0 after trying to flash (around 0.004A from the correct 0.041A). When trying to flash the uC these are the errors/log I get:10:37:32 : ST-LINK SN : 55FF6E067871515343241267 10:37:32 : ST-LINK FW : V2J39S7 10:37:32 : Board : -- 10:37:32 : Voltage : 2,60V 10:37:32 : SWD freq : 4000 KHz 10:37:32 : Connect mode: Normal 10:37:32 : Reset mode : Software reset 10:37:32 : Device ID : 0x466 10:37:32 : Revision ID : Rev 1.1 10:37:35 : Error: Database: There's no active configuration for this device.

if i will change this codition to "off" state during program excuation it will change to "off" .but when i change screen to another screen the position is came to starting point "on".how i solve this ?

Hello, there is a bullet in the STM32L0 HAL that escape me. On page 38 of UM1749 it is said:"When a status bit or a flag is read from registers, it is composed of shifted values depending on the number of read values and of their size. In this case, the returned status width is 32 bits. Example : STATUS = XX | (YY << 16) or STATUS = XX | (YY << 8) | (YY << 16) | (YY << 24)".Can someone give me a function/macro that implements it so I can look at its implementation?Does anyone know what case "In this case" refers to?Does anyone know what XX and YY refer to?If someone can give me a concrete example, I would greatly appreciate it.

Hello,is there any example of a TFM application that is supported by STM32CubeIDE?I came across the iot-reference-stm32u5, but the structure of the project is way different from any other TrustZone and TFM examples available as part of the STM32CubeU5 Firmware Package and find this a bit confusing.Would really appreciate if someone could shed some light.Many thanks

Hi, I'm doing a project with STM32F769I-EVAL.In my project, I set Timer 2 Channel 1 to input capture mode, and I made a clock to TIM2 CH1 Pin with Function Generator. And Timer 5 Channel1 to PWM Generation CH1 to make a PWM.I calculate frequency of input clock and set same frequency to Timer 5 and start HAL_TIM_PWM_Start and It works succefully.Now, I wonder how to generate PWM same phase with Input clock.Can I generate TIM5 PWM signals when Timer 2 update event occurs to generate same phase with Input clock and TIM5 PWM Signals?

hello,I am working with ST25RU3993-HPEV baord. Getting all the list of inventoried tags in GUI (ST25RU3993 Reader Suite). I have gone through the ST25RU3993 SDK and tried to change the code to print the list of tags in uart. But iam unable to do so. Please help to identify the necessary chages required for printing the list of tags in uart.Tahnk you

2 years ago it happened that the controller turned to brick. I corresponded with technical support for a long time and I was offered to send the controller to the factory or representative. But since the case was a single one, I did not take advantage of this case and forgot about it.Now there is a situation that, probably, everyone who uses this chip has, namely, that for unknown reasons it turns into a brick.I re-read all my messages in the STM community, but to my surprise, the post in which I described the transformation into brick disappeared.Today I have about 70 controllers with which I cannot do anything because they are not programmable.I decided to understand the reason and found it.The reason is well described in the post:https://community.st.com/s/feed/0D53W000010si7oSAA?t=1676280731376But for all this time, not a single STM employee has given a clear explanation of why this is happening.The question is simple: why sometimes, after loading the stack, the chip register SFSA

I managed to program the FLASH_OPTR user option bytes and set the SRAM2_ECC to zero (enabled). But when restarting the µC the RAMCFG_M2CR ECCE bit is not set and the RAM ECC is not active. So during startup when the .data section is initialized in SRAM2 the ECC is not active. And Activating it later directly leads to constand ECC single error interrupts and ECC double error interrupts, when reading RAM constant that was initialized before the ECC activation. What do I oversee so that the ECC is not activated on restart?

On the STM32 SAI peripheral, there's a member of the SAI_InitTypeDef which is:​ uint32_t OutputDrive; /*!< Specifies when SAI Block outputs are driven. This parameter can be a value of @ref SAI_Block_Output_Drive @note This value has to be set before enabling the audio block but after the audio block configuration. */​However, I can't find any docs on what that means or does anywhere on the documentation or even on Google. Could someone help me understand it?Thanks

This code only works when I'm debugging step by step. Otherwise, it always sends ADEN low again, which should not happen!! (Correct sequence: ADEN goes high then ADRDY goes high and both stay high...) (Note both ADEN and ADRDY are low before line 54 of pa1_adc_init() function) The reference manual says...Maybe I need this "time-out management" but I don't have a watchdog timer enabled so unless I'm understanding incorrectly, I don't think that's the issue.The issue occurs on lines 56 and 57 of my pa1_adc_init () function below. #include "stm32f0xx.h" #include "adc.h" #include "uart.h"   int ADC_VALUE = 0; // Global variable to store the ADC value (only 16 bits are useful) volatile int PA1_ADC_VALUE; // Global variable to store the PA1 ADC value (only 16 bits are useful) volatile int TEMPSNS_ADCVALUE; // Global variable to store the Internal Temp Sensor ADC value (only 16 bits are useful)     int main (void) { //int ADC_VALUE; uart2_tx_init(); pa1_adc_init();

I successfully implemented a service with different characteristics. However on the android side when I call getDescriptor()descriptor =characteristic.getDescriptor(UUID.fromString(CLIENT_CHARACTERISTIC_CONFIG)); CLIENT_CHARACTERISTIC_CONFIG = "00002902-0000-1000-8000-00805f9b34fb";It always returns null. I need this to set the notify command to be true. In the ST BLE Toolbox, this works perfectly. So in principle, this should be able to be called. It seems that I missed a setting in CubeMX.

I'm starting with the wb15. For this I followed the video series and currently I'm stuck at https://www.youtube.com/watch?v=lFDMBeJpib0&list=PLnMKNibPkDnG9JRe2fbOOpVpWY7E4WbJ-&index=15Even following every step in the cube setting I'm not getting any advertising from the board. I turned on the debug to monitor the logs of the m4 core but nothing appears.In comparison I took the Heart Beat example project, applied the same steps in the ioc-file and managed to fullfill this tutorial and get log from the debug. For learning purposes however I want to do this from sketch.It seems that appart from the cube settings to generate the code, the app which launch the BLE needs some commands in the C/C++ files. This however is not mentioned in this tutorial series.
