STM32U0 is the first Cortex-M0+ with a static consumption of only 160 nA in standby mode with RTC (Real-Time Clock) and 16 nA in shutdown. It also achieves 118 points in CoreMark and targets SESIP level 3 and PSA level 1 focusing on firmware code pro...
I'm quite confused when it comes to alignment.I opened linker script to make some modifications, so that I can fit two binaries into flash. (Relatively new to embedded, but frankly I learn fast).I use stm32f091Rx. Which has 256kB of flash memory.A li...
Hello everybody,On actual project, I need to interface my STM32F051C8 to a HTS221TR Temperature & Humidity sensor.Communication is through SPI1, STM32 is master, there is 1 bidirectional data line, 1 clock, 1 Slave Select.Final usage will be in polli...
Board: Nucleo-144Chip: STM32L4R5ZIT6PHey all!I have a curios problem when executing code from SRAM. My firmware lies in flash and occasionally jumps to a externally loaded binary in SRAM. As the cycle count of this binary is quite crucial, I used the...
I supply my STM32G4 with 3.3V. The 3.3V is more like 3.246 Volt. The VREF+ is connected externally to VDDA, which is connected to the 3.246V.My VREFINT_CAL_ADDR is 1662. On the Vref channel of the ADC I measure 1465, so I calculated 3.4034V for VDDA....
Hello,I can't figure out why the STM32H747I-DISCO does not start when I connect an CR2032 Battery to vbat.After turning the external powersupply off and on again, nothing happens and the debugger is disconnected.So I can't easily debug where exactly ...
Hi,I'm currently working on a project with the STM32H750. This project should be able to go to stop mode and wake up with a button press. The normal application/operation (before going to stop mode) is working properly on both revision V and revision...
Hello, Basically i am trying to get data at GPIO with inc with clk. The clk is used as a interrupt. The speed of interrupt is 500KHz.Here i am able to detect each intrrupt but i am missing the data at GPIO and not able to get the same data every time...
We are having problems getting a PWM output from Timer 1(nothing on the PC10 pin.) STM32G070 Low Level drivers Alternate function 2 of PC10 is Timer1 channel 3 Code is based on STM32CubeG0-master\Projects\NUCLEO-G070RB\Examples_LL\TIM\TIM_PWM...
I'm just starting to learn how to program ARM microcontrollers using ST's HAL. So I have this code which generates a 1khz and 20khz signal using a timer in output compare mode. That all works well and I tested it with a scope and it's as expected. Th...
This is the only µC from the family which has not CORDIC according to the page here:https://www.st.com/en/microcontrollers-microprocessors/stm32g4x1.html#productsIs this true? why is this the only from the family to not have cordic function?
