I am always curious about how does a fitness tracker work. So i did a preliminary search and found this page. https://www.st.com/en/applications/wearable/fitness-trackers.html#overviewnow I would like to know how to design a schematic based on stm32l...
Hello Community,in my application data is transferred between two MCUs using a UART. One of these MCUs is a STM32F429. It often detects frame and noise errors. I am aware of how a frame error is detected, but I can't find any information in the Refer...
Hey, Can the dual SPi Line be used as a slave? I should be able to interpret 2 bits with a clock of 16.368Mhz. in connection with the dma, of courseIs that possible with an STM32L476G Discovery board?
Hi,I am reading value of SYSCFG_CFGR3_VREFINT_RDYF to be "1073741824". How do I interpret the value of VREFINT_RDYF from the value I am reading?
Hi everyone, we have a problem using LPTIM4 PWM output on STM32H747I-DISCO when system enters STOP mode.In this project, I need two independent PWM outputs with fixed frequency to work, while system goes to STOP mode to save power. LPTIM1_OUT & LPTIM...
Hi everyone,So, i would like to test SPI1 communication on my stm32F103, using just the clock and MOSI line by sending 0x55 data on MOSI line , but when i see the traces on logic analyzer, i'm getting a weird values !as seen in this capture picture, ...
I am trying to emit data on SPI MOSI without enabling the corresponding SCK pin. This is useful for instance to control WS2812-type LEDs.However when I use `HAL_SPI_Transmit_IT` to transfer 3 words, the IRQ Handler gets called 3 times (triggered by ...
Hi!I'm using an ADC line of the STM32 MCU to read battery voltage that goes from 6.7V to 8.4V.The battery voltage is given to the MCU via a divider (by 4, so the maximum voltage given to the ADC line of the MCU will be 2.1V).I wanted to know, if ther...
