SPI Slave NSS input not consistent

So I'm having this weird bug I can't seem to figure out.I'm trying to connect two stm32f4 discovery boards through SPI.The master is sending out a SS signal I want to use to synchronize with the slave.However for some reason before I send out a messa...

Bluepill HC4067 via Arduino IDE

Hi everyone. I´d like to use a HC4067 mulitplexer to expand analog inputs on a bluepill. I´m using Arduino IDE to program the thing. But I can´t get reliable results. The values are jumping up and down or not reacting to input (potentiometer).I´m won...

hard fault when calling SBC_CleanDCache

I had some wrong bytes when transferring data over SPI, so I tried to clean the DCache. But I get a hard fault if I do this:I'm using the NUCLEO-H723ZG board.

Hi all, I'm trying to configure my NUCLEO-H745ZI RAM as Device mass storage, i followed some tutoriels showing how to do this application with CubeMX and Keil IDE but its not working for me. I write my code only in "usbd_storage_if.c" file.

The code compile, load it to flash memory and enter debug mode to run the program.When i connect the usb connector present on the board to test if the computer will detect it as an usb device mass storage, nothing happen ! Can someone help with this ...

How to measure the resources (run time / memory consumed) by having part of the code block in external memory encrypted (while using OTFDEC in L5 controller).

I am using STM32L562VE controller. I have configured OTFDEC with a portion of my code encrypted. Is there any way with which I can measure the run time and memory consumed promptly eventhough the code switches back and forth between internal flash an...

M95M02 eeprom Read And Write

Hello All ,I Am working On Interfacing M95M02 EEPROM With STM32 .Anyone Have Example Code for the same that is very helpful for me

How do I check the MCU availability and production plans? Looks like a shortage of STM32F303CCT6 and no information of future availability plans. When does the MCU go obsolete? Is there a roadmap? Regards, AJ
