Hello, i have probem with backup registers, which are powered from VBAT pin on Dicsovery board.First problem was CubeMX init, where i can't choose LSE source, because the value of clock box, was not active. I tried differend things like change txt c...
hello everyone !i'm using a nucleo board (NUCLEO-F401RE) to program a MCU STM32F301 placed on newly fabricated pcb; the mcu has never been programmed.i have disconnected the jumpers to use the CN4 connector. i have just connected the SWCLK (clock sig...
i have interfaced opt8320 optical sensor to stm32f446zet.I hav configured STM as master and Opt8320 as Slave. Can i initiate continuous registers read from sensor using I2c ?Please share suggestions regarding this issue.
I am more of a assembly guy. So I have problem in understanding the functionality of I2C control registers. It would be helpful if you could provide an outline or a pseudocode as how to write to a register or how to read from a register ? How to writ...
I want to use a STM32F103, STM32L431, 451 and 471 microcontroller, but i don´t know if the crystal that i selected (ABS07-120-32.768kHz-T and ABMM2-8.000MHZ-E2-T) is valid for this microcontroller.And another question is how to calcule the load capac...
Hello! I use CubeMX to generate the init code for rcc whith LSE Crystal NX3215SA-32.768KHZ-EXS00A-MU00525 (32.768K,6PF), two 2.7pF capacitors and rtc module. Program goes to error handler after "if (HAL_RCC_OscConfig(&RCC_OscInitStruct) != HAL_OK)"-s...
hello. I am an embedded software engineer from China ,At the moment I'm tryingDrive emmc on stm32l4r5 ,but I failed .Who can give me a demo about how to drive emmc on stm32l4xx , thank you
Posted on January 07, 2016 at 16:29 Hi, I'm developing an IAP application for firmware upgrade over GSM network. I've a SIM800H module connected to STM32 over UART interface and I'm able to establish GSM connection, setup HTTP GET request an...
Hi, I am looking for a way to determine what caused a wakeup from standby mode, in my case the options are RTC or the WKUP pin (and if you have multiple, which pin). In my case I only have one WKUP pin, so I could check the RTC and conclude if it was...
Hello,looking for a STM32 in small package with pins where optical solder inspection is possible, I hoped that the MCU Selector from STCube would offer me a checkbox to select devices with Voltage reference buffer output. I did not find that checkou...
