I'm using the Nucleo32L031 board connected to a Adafruit TCA9548A 1:8 multiplexer board. I have the board setup properly, Vcc = 3.3, GND, SCA and SCL pins double checked. I have a Sparkfun TMP102 temp sensor board connected to the TCA9548A's port0.I ...
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...
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...
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...
Hi I am trying to initialize TIM2 to get a PWM outpt from PA15 of my STM32F407 development board. Here is my TIM init function:void TIMConfig (void) { /*************>>>>>>> STEPS FOLLOWED <<<<<<<<************ 1. Enable the TIM2 clock 2. Set clock ...
Hi All,I have been breaking my head the past few weeks trying to connect an SD card to the STM32H723ZG with no success.My setup is simple:Evaluation board is NUCLEO-H723ZG.SD card breakout board wired using 4 bit SDIO.47K pull up resistorsusing CubeM...
data needs to be in a row but there is shifting how can i fix this
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....
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...
