I read and display the CPUID and REVID on my project.I see the difference between using an U575 chip vs. U5A5 chip (NUCLEO boards): U5A5: CPUID: 0x410FD214 REVID: 0x30016481 U575: CPUID: 0x410FD214 REVID: 0x20016482 OK, based on ARM Cortex-M33 docume...
I am using HRTIM in my project such that the output TA1 of timer A generates a delayed pulse after the timer is triggered via the EEV1 input. I have two compare values defined in Advanced configuration mode: One to set the output high and the other t...
Changing VRef source would seem simple, but it doesn't work, there is no change in the levels the ADC records. __HAL_RCC_VREF_CLK_ENABLE();HAL_SYSCFG_DisableVREFBUF(); // Disable the Internal Voltage Reference buffer, uses external 3.3vHAL_SYSCFG_VRE...
Hi ST Community, I am trying to measure system voltage (Lead Acid Battery) using ADC input of STM32F030C8 (PB1). The system voltage can be between 9V and 13.5V () so I am using voltage divider (10k and 1k) to lower the voltage to the 0 - 3.3V range. ...
Hi everybody,I'm trying to connect to the STM32H743IIT6 on my custom PCB via JTAG. It seems it responds, I traced it with a logic analyzer (attached). I'm not too knowledgeable with JTAG Protocol, but the 0x5253000 the H7 answers seems not to be the ...
Hi i am able to enter stop mode but after returning stop mode again i am unable enter stop modeHAL_RTCEx_DeactivateWakeUpTimer(&hrtc); HAL_RTCEx_SetWakeUpTimer_IT(&hrtc, 0x3FFF, RTC_WAKEUPCLOCK_RTCCLK_DIV16); HAL_SuspendTick();HAL_PWREx_EnterSTOP2Mod...
Posted on March 30, 2017 at 18:49Hi, I'm using the cubeF4 to work on FATFS application and i'm searching for a function in FATFS library that can return the content of the SD Card: number of files and their names. Thank you.
I'm working with an STM32F217 and I have a few timer channels setup as sync clocks to regulators (around 1.5 MHz). I'm checking to make sure my sync lines are actually using HSE as a reference clock by looking at the phase drift between my external o...
hiwe have requirement of SIL2/ SIL3 verified microcontroller which have 24 adc channel, UART(2), ETHERNET, CAN(2),SPI,I2C, 512KB FLASH ETC.kindly suggest us
Hello everybody!I am using an STM32H750VBT6 controller and a NAND memory - MX30LF1G18AC. Initialization via CubeMX, using the development of a Keil.I can view the id, I can record and view all the entries: HAL_NAND_Write_Page_8b, HAL_NAND_Read_Page_8...
