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...
Need a help to work out the formula. I cant get my head around with this to work out. its polynomial with numerator and denominator. what is the formula for this. Thank you FLOAT_TYPE num_coeff[] = {-2.42580348918581e2l, 4.43575581447635e2l, -8.65706...
I've got the I2S working with DMA as slave receiver, works great, bit perfectly fills receiving buffer,until I restart the master, or introduce noise to I2S bus, then it just loses it, fills buffer with nonsense after that.It's not able to resync to ...
Hi, I want to design a board using STM32F446RET6 MCU. But I have a question about how to properly power the ADC system, and what the VCap_1 pin is. I read that I need to put a 4.7 uF ceramic capacitor with low ESR there. Below is an introductory grap...
Hi,We are planning migrate our product based on STM32G431CBU6 to STM32G474CCU6. Need to make sure they are compatible in hardware design, are the two pin-to-pin compatible?Thanks.
Wich eval board mcu stm32 recommend me to learn and in the future can match with dsp.Regards
Hi All, Been reading and learning a lot about MCU's in general. I'm very very new to all of this so please bare with me.The board comes with STM32F427, and a custom .exe that can flash directly via USB-C. I've read about fake STM32's, and. I'm not su...
Hello I wanted to create a external loader for STM32F411CEU6 (WeAct Blackpill board) and W25Q64 flash memory chip. I did it based on the tutorial from youtube link: https://www.youtube.com/watch?v=KlG2doCkREM&t=1792s I the tutorial i found link to W2...
So DMA can read/write from 16bit SPI DR, to 32bit memory variable, in circular mode,I need to reinit stream, but DMA TX ends up off by one 16bit in destination array,so how can I partially reinit DMA to beginning or array/or even addresses?Without fu...
hey!im working on data logging and want to store all data in text filewhere i want to save date and time with the use of RTC clock and external interrupt based on timer with gap of 1 sec i have things configured correctly for the RTC which works fine...
Hi I have a stm32L433, and setup Uart1 for standard TX and RX with interrupt for both send and receive (9600N81 setup). I don't use any hardware handshake . Within the IRQ routine occasionally the USART_ISR_EOBF bit in the ISR is set , and I am not u...
