Hi ,We are working on configuring an ISSI Octal Flash memory in DTR mode on the STM32U5 platform and would like your assistance. We successfully executed the example provided for Macronix in document an5050 example (II. Octo-SPI FLASH in Regular-comm...
Hello,I am trying small example LED blinking written in assembly only - see below. LED is placed to PB15. I am able to compile the program without error using this commands:arm-none-eabi-gcc -save-temps -nostdlib -nostartfiles -mcpu=cortex-m3 -ffrees...
Hi,I'm new to the ST32 world and would like to know if this is possible before I start experimenting with an STM32F405:Is it possible to use both USB interfaces as a USB host at the same time (only full speed and low speed, no high speed is required)...
Trying to make a phase shift PWM for a DAB converter, i managed to do this exact functionality with normal TIM1 (Asynchronous mode), but im very very lost with HRTIM. I am able to produce complementary PWM signals for TIMA1 and TIMA2, and TIMB1 TIMB2...
Hello,I need to understand the implementation of using output compare with timers as a basis to tackle a more advanced project. My start point/goal is a timer with a period of 3 seconds and it toggles when CNT equals 800ms(CCR1). Clock is running at...
Hello! I am trying to implement a phase-shifting full bridge on the STM32F334 microcontroller using HRTIM. Two PUSH-PULL outputs and a phase shift between them, this is necessary for the LLC converter.I configured the master timer as an event source ...
I want to use open bootloader on STM32H747 controller. I found that ST provides support for STM32H5 but not STM32H747. Can I use it for STM32H747? How can I port to my target controller?
Hi,I am using the STM32G474 with HRTIM for the propose and also STM32CubeIDE.Is there any specific guide to make a four outputs (90 grades) PWM with dead time?The duty cycle must be changeable as well.I already read the relevant reference manual and ...
I'm a little confused about the descriptions of the ADC VDDA, VREF+ and input voltage range.Do I understand it correctly thatVDD is the device supplyVDDA is the ADC supplyVREF+ is the ADC referenceIt says VREF+ can be supplied internally as 1.8 V, 2....
Hi,We are using STM32L452 for our project.We have problem with pin NRST.We set a 30K pull-up resistor (with pull-down capacitor of 0.1uF).Sometime voltage on the NRST pin is 3.3V and sometimes it is 1.4V.In cases it is 1.4V the MCU is stuck.We think ...
