Resolved! How can I divide the driver file into two source files without having multiple definitions error?
I wrote a simple GPIO driver for Nucleo-l432kc board I used one GPIO.c file and multiple headers for RCC GPIO ..etcI added the main method in the same file GPIO.c and it worked fine now I moved the main function to another file main.c (to isolate the...
I am working on STM32G030 series microcontrollers & I am using external crystal as clock source (HSE). But as per AN2867 Application note(page13) gain margin ratio should be greater than 5, But I am not able to get it above 2.9. What should I do?
STM32G030C8T6 has maximum critical crystal transconductance (gm) is 1.5 mA/V.Crystal specifications that are mentioned in application note(page14) gmcrit = 0.23 mA/V with this gain margin > 5. But I checked many crystals datasheet but I am not able t...
SPI slave send and receive 1..n bytes - what if less bytes are sent?
Hi,i want to utilize an unknown number of SPI slaves which will send and receive e.g. a byte of data each. patching them together has to be as easy as plugging an ethernet cable BUT some data is used by multiple slaves.Let's say I have a maximum of 3...

STM32H7A3 STM32H7A3ZIT6Q DMA Not starting
The code works fine on STM32G474 and I can get 1Msampe/second. I redid the same project on STM32H7A3ZIT6Q with the changes indicatedhttps://community.st.com/s/article/FAQ-DMA-is-not-working-on-STM32H7-devicesI went to the option having a dma section....
Resolved! Casting / Pointers creating immense grief???
I have the array of character strings that I am trying to printout to Real Term using a Nucleo -F072. The code compiles with no warnings or errors, yet every time I run this it jumps into the HardFault_Handler....Can someone please tell me what am I...
