Hello..I have a few problems, can you help me?I am using FatFS on stm32f103RB MCU. I have a Single SPI bus and 2 CS pins for 2 SD Card.used STM32CUBEIDE. No problem when I use 1 SD card and 1 CS pin. But Problem occurs when I use 2 SD Cards. Problem ...
I try to copy Ethernet connections from H750 Discovery board to H750 having LQFP package without any changes. I am not very good at C and even worse Ethernet programming, so I don't want any HW changes. But 144 pin LQFP doesn't have PH2 MII_CRS and P...
i try to implement stm32f10c example on a custom board with stm32f107 as my controller but it causing the controller to always goes in to hard fault please suggest what to do
Hi guys, Ill keep this short, anytime I set the I2S bus to use FWS = 196KHz it acts all whack.I am not sure if its the tool I am measuring with but its a saleae logic analyzer so I doubt it. Here a picture of what I am talking aboutI double checked e...
Hello everybody,I am currently using a stm32l4R9 and it's communicating with a RTL2832u over USB FS. The initialisation works perfectly (using USBH_CtlReq). However, when I use USBH_BulkReceiveData I can see a frame transmitted on my oscilloscope but...
Hi,For one project i have to save some pictures taken with one SPI Camera into an SD Card by SPI and i have to save also some info related to the image. For saving the pictures i am going to use FATFS and i was wondering if i could save some Exif inf...
I am trying to interface DS18B20 (Temperature Sensor) with STM32L072 using OneWire communication. But not able to generate proper delay.I have reached some of the solutions but did't worked.https://community.st.com/s/question/0D53W000003LJZsSAO/micro...

I am working on a project that requires 3 channels of ADC1 and FreeRTOS.I am using STM32F446RCT6. I start ADC conversion at the start of the code HAL_ADC_Start_IT(&hadc1);Here is my implementation for ADC callback.whereas array to hold data is descri...
I'm using STM32H745. Both cores run FreeRTOS 10.2.1. Timebase for CM4 is TIM6, and CM7 is TIM7. For some reason, on CM4, from the time osKernelStart() is called in main() until StartDefaultTask starts to run is about 5 seconds ( i turn an LED on just...
