What precisely is the resynchronization drawback when using adc_ker_ck?
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...
Resolved! STM32 rise/fall shape
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...
what is the sampling time in ADC ?
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 ...
Trigger ADC by timer
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...

Resolved! Beginner problems with 2xSPI and RTC
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...
Which NUCLEO board shall i use for my (target) STM32L431?
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
Output Two ADC Channels Over UART
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...
How to create an fsdata.c file
trying to create a simple web page. I am using an fsdata.c file from one of the example projects and everything seems to be working. Now, I created a simple html file and need to convert it to an fsdata.c file. I have looked up this topic at vario...
