Posted on June 19, 2018 at 14:13Hello everyone,I'm currently trying to get as accurate ADC values as possible from a STM32F072. I'm using the NUCLEO-F072RB and wanted to use the internal stored reference voltage value for calibration. But I'm alread...
Posted on December 17, 2015 at 10:06Hi,We are working on a design utilizing the STM32L151 MCU, which is to be programmed over a UART link using the internal bootloader. Selected baudrate for programming is 115200 (with even parity).The issue we are ...
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...
