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...
I am trying to configure my stm32L4 device clock for 80MHz with PLL I am trying to understand a piece of code i found online could someone explain what the c code below meansRCC->PLLCFGR = (RCC->PLLCFGR & ~RCC_PLLCFGR_PLLN) | 20U << 8; RCC->PLLCFGR =...
WHEN TRY READ ADC WITH DMA DMA ERROR TRANSFER FLAG SET DMA STREM CHANLE DISABLE AUTOMATIC FOR SET DMA CORRECTLY MUST CERFUL ABOUT WHICH PARAMETER
Hello,I want to use ADC1 and 2 with close to maximum sampling frequency. Now I found on page 899 in RM0433 Rev5 a note that there will be a resynchronization between adc clk (using adc_ker_ck to achieve the highest possible clock) and AHB1 clk. I don...
Hi, guys. I boughtSTM32F446RE, mbed-Enabled Development Nucleo STM32F4 MCU 32-Bit ARM® Cortex®-M4 Embedded Evaluation Board (NUCLEO-F446RE)https://www.digikey.com/product-detail/en/stmicroelectronics/NUCLEO-F446RE/497-15882-ND/53477128MHz ±10ppm Crys...
I am using STM32F446 and I see 15 cycles for 12 bit ADC which gives 1.5 Msps for 180 Mhz clockBut I see on the bottom sampling time from 3 cycles to 480 cycles under something called rank.does it means that it would actualy do one sample in 3 cycles ...
I'm having some difficulty getting this to work. This post is a very good description of the my confusion: https://community.st.com/s/question/0D50X00009XkghxSAB/triggering-adc-sampling-by-timer-eventsHowever the conclusion is not helpful. TRGO upda...

Hello, may someone help me with these peripherals? I have never used them on any ARM.I am using STM32F051C6T8 in this project.My setup, I have two shift register chains connected to SPI peripherals. I am using two peripherals, because two types of re...
Hi.I cannot find any NUCLEO boards to exactly my MCU (STM32L431), so which NUCLEO should I use? Maybe the NUCLEO-L433RC-P? Will example code generated on the NUCLEO-L433RC-P run on my target?Best Regards Terje
I'm using the nucelo STM32F446RE dev board and attempting to output two ADC channels over UART (technically I think it's USART). I Can see in the debug tab that I'm reading the ADC channels correctly. I had been reading out one channel over UART 2 (t...
