Hello Community,I am slightly confused while selecting the external high-precision Clock source for our application that uses STM32G474RxT3 series MCUs. I want to use DSC1001DL2-024.0000T as I have these in our inventory, I checked for the operating ...
stm32l071CB flash only 128kB, can fatfs run on Stm32L071CB? Roughly how much space it takes up?The FATFS I used to use on the stm32F103VE platform took up about 200KB of flash because of several large arrays。
HiI design a board based on the STM32H7xxI-EVAL, the ethernet PHY is LAN8742A-CZ-TR and according to its the datasheet the crystal specification the drive level need to be 300uW but the maximum drive of X53T-C20SSA-25.000MHz level is only 100uW.Did y...
I come from the PJRC Teensy 4.x after many years playing around with it and building a product or two based on it. (NXP IMXRT chip)But for a new project I need to be able to rapidly calculate the RMS value of an AC sine wave from an audio signal, wit...
Posted on December 20, 2017 at 18:49Hello,I'm trying to bring up the CAN bus on the STM23F303RE nucleo board and am having some difficulty determining which way to go. I've been unable to find a HAL library example for this platform. Can anyone po...
How in the world is this happening now? Just made some changes there. Renamed and changed the values.The first line has "missing whitespace after the macro name" Aprilfools day is still not here yet!

I am a new user of H563ZI, and I have read the datasheet. I wonder if all pins that can be viewed in cubeIDE can be used as a GPIO pin?For example, as mentioned in the datasheet, PB2 is used as QSPI_CK when solder bridge configurations are not change...
Hi AllI am working on a data logger code. It is basic at the moment.1, set a an ISRTimmer for 1sec.2, When ISR triggered i set DataLoggerFlag.3, Next loop thru main() i test DataLoggerFlag, if set go to a function and read A0, A1 ports and store back...
