I am using STM32L496ZG to interface ISSI IS29GL064-70TLET nor flash by using HAL library. I used CUBE MX to generate the code and running code on Keil compiler. I am able to detect device ID, write and read block. But unable to erase data. I have used example code provided in application note AN4761. Erase code snippet is below:WRITE_READ_ADDR 0x8000NOR_BANK_ADDR 0x64000000 HAL_NOR_ReturnToReadMode(&hnor1); /* Erase the NOR memory block to write on */ HAL_NOR_Erase_Block(&hnor1, WRITE_READ_ADDR, NOR_BANK_ADDR); /* Return the NOR memory status */ if(HAL_NOR_GetStatus(&hnor1, NOR_BANK_ADDR, NOR_TIMEOUT_VALUE) != HAL_NOR_STATUS_SUCCESS) { /* Erase Error */ HAL_UART_Transmit(&huart2, (uint8_t *) "Erase error" , 12, 100);  return NOR_STATUS_ERASE_ERROR; }The status returns erase success. But the bits are still the same, they don't turn to ones at all.Can any one please help me out on this?

I did not find a real UserManual for STM32WB55, with the register-definitions, peripheral explanations etc.?

Hi,is there an error in the datasheet? The data seems counterintuitive:FT pin input leakage current (max.) is- 150 nA for 0 to VDD-2500 nA for VDD to VDD+1V-250 nA for VDD+1V to 5,5VShouldn´t the last value be in uA perhaps?Kind regardsRené

Hi All,I'm starting to get familiar with the STM32 Series of Microprocessors and I'm completing some exercises using a mixture of direct writting to peripherals and low level ST libraries using the CUBEMX to get familiar with the chips. I'm using the Nucleo -F072RBAt this point I stumbled across a challenge, regarding the ADC module. I don't seem to be able to read the values on chanel 2 and 3 (PA2 and PA3).Using the code below I can read PB0 (Channel 8) just fine. I ave also tried to read te internal temperatre sensor and reference and they seem to work fine. Any ideas why the inputs at PORTA don't work?My code to read the ADC is as follows:... ADC1->CHSELR = (ADC_CHSELR_CHSEL3); while (1) { ADC1->SMPR = 7; // Sample Time ADC1->CFGR1 &= ~ ADC_CFGR1_CONT; // Discontinuous mode ADC1->CR |= ADC_CR_ADEN | ADC_CR_ADSTART;   while ((ADC1->ISR & ADC_ISR_EOC) == 0) /* Wait end of conversion */ { ADC_Result[1] = ADC1->DR; /* Store the ADC convers

Looking for Part numbers for modules on the B-U585I-IOT02A dev kit, specifically the Bluetooth and WiFi modules, but also looking for part numbers on the modules listed below. Didn't see P/N's listed in the datasheet but maybe I was looking in the wrong place:-Bluetooth Module-WiFi Module-2 digital microphones-Relative humidity and temperature sensor-3-axis magnetometer-3D accelerometer and 3D gyroscope-Pressure sensor, 260-1260 hPa absolute digital output barometer

Hi, I'm working on a new project in which I'm using a custom stm32u599 with a 5inch tft display with MIPI interface , I can't find much documentation about using MIPI or setting up such interface to work with touchgfx , can anyone provide some guidance about how i should get started ? thanks

Hi,In my project I need to bring up stm32g4 IC in custom board. Can anyone tell me the process to do that.1. Bootlooader flashing: Do we need to flash the bootloade in to IC?if Yes,Where can I get the bootloader for STM32G4 IC.What is the process to flash it into IC with STM32Cube iDE and debugger.Do I need anytool or any configuration settings I need to do.Can anyone please share the resource link if available.2.With debugger do I need to use?I have IAR I-Jet debugger/JLINK V9 J-LINK Debugger Emulator High Speed Firmware debugger with me can I use these for flashing the firmware with stm32 Cube IDE.Thanks

Hello everyone,I am using an NFC08A1 for my project and I would like to use the AAT. I roughly understand what happens in the AAT algorithm. However, I don't get any noticeable improvement when I apply it. The range in particular remains almost the same.An external antenna is used in the project and I would like to achieve optimum performance. Which default values do I have to change in the algorithm to achieve this? And when does it make sense to call the AAT? Later I want to switch between two readers. Is it necessery to call the function everytime I change the reader or is it possible to store the best configuration. Rgds

Hello,I'm using the IMP34DT05 available with the STEVAL-MIC003V1 kit to record audio the nucleo-f401re. I'm using the PDM2PCM library to convert the PDM stream to PCM data. The audio is recorded at 8kHz.I have tried reproducing 1kHz tone on the microphone. Unfortunately, after recording and listening to the .wav file on the computer it appears to be really noisy.Do you know how can I solve this issue?I have tried increasing the sampling frequency to 16kHz without success.I upload the recorded .wav, by looking at the FFT the 1kHz peak is present. However, if you listen to the audio, playing it in audacity it is really bad. The signal-to-noise ratio seems to be really poor.Any suggestion is welcome.Thanks.

Hi,We are currently in a project where we want to use the VL53L0X chip for ranging. And the example code with PC application seems to work quite good. the next step is to create a PoC using our own system (where we are now).I am currently reading up on the sensor guidelines, API documentation and code examples and can't really explain the return values of the 'VL53L0X_GetRangingMeasurementData' function. According to the documentation it returns the following:RangeMilliMeterRangeDMaxMilliMeter:SignalRateRtnMegaCpsAmbientRateRtnMegaCpsEffectiveSpadRtnCountRangeStatus:I can explain the 'RangeMilliMeter', 'RangeDMaxMilliMeter' and 'RangeStatus' variables but the other ones i dont fully understand.The code example says the following: SignalRateRtnMegaCps:                        /*!< Return signal rate (MCPS)\n these is a 16.16 fix point      &n

Attached is my demo project for the NUCLEO-WB55RG dev kit.I'm trying to report ZCL_TEMP_MEAS_ATTR_MEAS_VAL when the attribute value is changed (button 3 pressed), but according to wireshark, nothing is send.See app_zigbee.c, line 329I can correctly read the value from the coordinator.What's wrong here? 

Hello,My TouchGFX application is outputting a static image in the GUI wrongly and I am unsure where the error stems from.Board: STM32H747I-DISCODisplay: Innolux G057VCE-TH1   (640wx480h RGB666)Without TGFX, I am able to output a chosen static image array correctly, and when it is on external memory. Thus, I believe my configuration for the LTDC and FMC is correct. When using TGFX, I set up breakpoints for the LTDC FIFO underrun interrupt handler, and it was never triggered. In TGFX Designer, whether I have the orientation as portrait or landscape, and fill it with the image filling the screen, the output is the same.This project was initially generated from TouchGFX Designer for the discovery board, and I gradually modified it to accommodate this display. An important change was commenting out DSI and old display controller calls (this new screen does not have a controller, it just uses parallel RGB).When I am debugging, the program does not run into any infinite-wh

Hi Everyone,I'm upgrading our firmware from STM32L432kb with 128k flash memory to STM32L432KC with 256k flash memory. both micro controllers are  exactly the same except for the flash memory size difference. To accommodate this change I changed my controller from project properties to the STM32l432KCu and changed flash memory size from 128k to 256k. we have reserved last page of memory as persistent(similar to EEPROM) memory. I'm getting PGAErr and PGSErr even before the debug session is initiated. i.e. when debugger comes to halt at init those 2 flags are already set.we can resolve the issue by clearing the error flags before other flash operations start. but we are concerned that ignoring this issue will bite us back in future.can anyone help me with understanding what might be causing the issue?

Hi all,I'm interested in utilizing a solar cell as the power source for my MCU project. To achieve this, I've implemented a power harvester that, in turn, employs the L6924D battery charger to efficiently charge a lithium battery. I'm seeking guidance on how to connect the MCU to this power source. Should I directly connect VBat and VDD to the battery, or should I incorporate an LDO circuit by connecting VDD to the LDO and VBat to the battery? Your advice on the preferred approach would be greatly appreciated.Thanks in advance 

I am using the ST25R3918 and the 'pollingTagDetect' example from the RFAL library. This chip does not have the ST25R3916_CMD_TEST_ACCESS register.How can I modify this library?

I’m new for STM products. After some google, I found mp157d-dk1, I want use it to study Linux kernel. Does the onboard STLink support Linux kernel code debug? Like set breakpoints/single step/observe variables values?Another question, is this boards newest model? Is there better/newer one? 

Hi,We are using STM32H745XI processor for one of our customer products. To start our initial software prototype development, we are looking for the evaluation kit. I went through the processor product page, and I have following queries:1. Looks like there is only one option STM32H745I-DISCO (Discovery kit with STM32H745XI MCU) available for STM32H745XI processor. Is there any other option available?2. From STM32H745I-DISCO product page, there are 3 IDE are supported (IAR Embedded Workbench®, MDK-ARM, and STM32CubeIDE) My question is STM32CubeIDE free to download and use or need to purchase the license? Which IDE will be best for getting started with STM32 series MCU?3. As per my understanding Programming and debugging capabilities is integrated into the STM32H745I-DISCO hence no need for external JTAG? Is my understanding correct?4. Is there anything i need to consider purchasing to kick-start our development?ThanksJigs

I have been working in Stm32wle5jci6,im trying to integrate My I2C code with lorawan code package downloaded from github. I had tested with Macros in that case the data was pushed in Chripstack, but whenever i try to connect the sensor i am unable to read the sensor data. Note : im using HTU31D sensor and its working. 

I am using STM32CubeIDE to develop a product with STM32H7 chip. I enabled freeRTOS in our software system. When I debug code, I can see freeRTOS tasks in "FreeRTOS Task list window" and I am in current task context. How can I switch to other task's context for debug?

Please tell me how to set the wake-up button (PA0:PWR_WKUP) as a return factor from LPLV-Stop mode and set STM32MP157f-EV1 to LPLV-Stop mode.
