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...
The new STM32H7R/S lines are built on the success of the STM32H7 series, offering even higher performance and security at a lower cost. The STM32H7R/S is a bootflash-based MCU powered by a Cortex®-M7 core running up to 600 MHz, with 64 KB of user fla...
Hi there,I'm using DMA to circular sample ADC channels. I'm getting the ADC complete interrupt - its all good. The question is, how do I set the sampling rate of the DMA, let's say that I need those samples every 2 milisec - how to I set the DMA to p...
I'm completely baffled as to how to make DMA and sleep mode work together on an STM32F0. I presume though that the issue is not family specific. It appears when the CPU enters sleep mode via the WFI instruction, DMA stops working. If a busy loop is u...
For whatever reason, I can't delete this post. It is closed, see resolution below.--------------------------Hello. We made a board that powers the VBAT pin of a STM32L431RCT6 directly from a coin cell battery. The LSE and RTC work well. But we reali...
I want to make i2c monitor that can read data sent by slave with specific address (0x42). So monitor has to capture sequence of1. Start2. Slave address (write)3. Command byte 4. Repeated start 5. Slave address (read)And then start reading actual dat...
I have a sensor which generate an input signal. By using this signal rising edge , I want to generate some pwm signals and additional Dac signal from DMA which synchronize with input Signal. When I visualize signals on ossiloscope , I aware some sli...
Hi, I am using the 176 Pin STM32F407 microcontroller. I want to generate the phase correct PWM using timer 4 ch1 and ch2, so please guide me for the same. The wave form is attached for driving a dual input boost converter. The "gate driver" image is ...
Hi everyone,I am trying to read a laser sensor through UART of STM32F4 inside Simulink. The laser sensor's refresh rate is 10 Hz approximately but it does not give the data periodically. I am using UART Interrupt for reading action. There are two cas...
I have 36 leds on my board. I will connect dimmer my board. How can i adjust leds brightness with dimmer? Because i need to manage 36 output pins. How can i do it?
Hi,I want to interface two SPI peripherals on the same STM32H743 nucleo, am configuring SPI1 as Master and other as Slave and connecting them with each other. Am transmitting in polling mode via SPI1 and receiving in interrupt mode on SPI3. I am rece...
