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...
Hello,I'm looking the vector table described in the Table 97 of the STM32G4 series reference manual, and it shows interrupts with different characteristics, such as TIM1_BRK/TIM15 and TIM6_DACUNDER, being allocated to the same address. This is very c...
Hi. I am using STM32H735VG for SPI communication with external ADCs.But I want to add external ADCs and I already used all 5 SPIs.So I will use OCTOSPI, can OCTOSPI play the same role as classic SPI?In menual, OCTOSPI in indirect operating mode works...
I having trouble getting the correct CAN timing configured with default 96Mhz System Clock on the NUCLEO-F412ZG eval board. I need a 250kbit/s baud rate. Here is what I have so far. The system clock setup is below.
Posted on May 26, 2017 at 13:35Hi,How do I enable the STM32CubeMX version 4.21.0 to generate sysmem.c file under startup folder? The file seems to be missing. The older version of STM32CubeMX automatically generates it.#stm32
Hello,I setup a USB virtual com port which I use for serial comm. My design has 2 boards; a panel-board and main-board. The main-board has an STM32F373 with a USB-C connector as well as ESD321DYAR diodes for DM and DP USB line protection.The main-b...
Hi,I am using a STM32L4ZIT6 MCU. I want to monitor 4.2V Lipo battery voltage on an ADC pin. I have experimented two approaches:First:I used a 332k - 820k divider in order to drain low queiescent current. This is an high impendance measurement, where ...
I am using two STM32F405's to read a switch and have some diagnostics.I interface this to an analog input on one MCU and a digital input (no pull up/down) on another MCU.However, I have cross-talk with the neighboring analog channels and more severe,...
This is one that baffles me:I set up Timer 8, and everything haasworking perfect. Then i did set up interrupt on some pins, and then the PWM signal on timer 8 stopped working.This is what i did, so the Timer 8 stopped working:Edit: Only with the pull...
All: I have connected internal temperature to ADC3, and I am able to display degrees C on "Live Expressions". The particular chip we are working with has an operating range of -40 C to + 85 C. If I am monitoring the internal temperature on a regular...
I am programming stm32h750 microcontroller.I managed to make work ADC2.ADC1 and ADC3 gives wrong results sometimes when change priority at DMA interruptI have programmed the ADC3 using DMA2 (not BDMA that not generates interrupts to me)Sometimes firs...
