Hi,I am working with STM32G491RE.I communicating ATM90E26 single phase energy meter with STM32 through SPI communication.I can able to read voltage ,current values correctly from the meter.For KWH calculation, I am reading Absolute active energy reg...
Hello there, I am working on a project using an STM3240G-EVAL board which as the STM32407IGH6 MCU on it. In this project, I want to use USB-OTG-FS to connect an external USB microphone to the board and then store any information sent into the micro...
Hello, i am trying to read internal temperature and vref values from ADC3. I shared ADC3 ioc settings. ADC clock mux freq is 96MHz and sampling time is set to ADC3_SAMPLETIME_247CYCLES_5.On init routine calibration line as below :HAL_ADCEx_Calibratio...
Hello There,I'm working on a FREERTOS based STM32H7A3 application.Upon debugging, my code randomly halts on UNALIGNED hardfault. The occurrence of this fault condition is very rare. During my testing in the last 30days, I ran into this for nearly 3 t...
Hi,I am using STM32G491RE MCU for my project. Is it true each STM32 IC has its own unique ID. For STM32G4 product has the UID facility. Is it 96-bit ID for all the stm32 families or is it different.Which manual has to be referred for this?If yes can ...
I understand the STM32H7's BDMA requires special attention to the memory map [FAQ: DMA is not working on STM32H7 devices]however, when I try to declare the buffer to SRAM4 that will be the destination for the ADC DMA transfer, __attribute__((at(0x380...
I am working on OTG FS application on stm32f769 discovery board, as per the it's schematic for OTG_FS VBUS power supply will be taken care by External Phy(see below image). So as per that I configure the STMCUBE IDE, and i disabled the VBUS_Sensing a...
Hi,I am working on freertos plus tcp library with STM32H563ZI, but how must I make memory otions in linker file?like: RAM (xrw) : ORIGIN = 0x20000000, LENGTH = 320KFLASH (rx) : ORIGIN = 0x08000000, LENGTH = 2048KRAM1 (xrw) : ORIGIN = 0x20000000, LENG...
I am making a product and trying to write a serial number. After looking into it, I heard that I can use the unique device ID to write the serial number, but I understand that the unique device ID is read-only. I am curious as to whether the previous...
The datasheet say:USB on-the-go high-speed (OTG_HS) The devices embed an USB OTG high-speed device/host/OTG peripheral with integrated transceivers. The OTG_HS peripheral is compliant with the USB 2.0 specification and with the OTG 2.0 specificat...
