Hi folks,i recently tried to migrate my SSD1306-I2C-display driver using DMA from "STM32Cube FW_F1 V1.6.1" to the latest "STM32Cube FW_F1 V1.8.0".The driver uses HAL_I2C_Mem_Write_DMA(..) routines and worked just fine on the old Cube firmware. Now wi...
I plan to use an STM32F7 to adress three different CAN-Buses. As the spec sheet says there are 3 available I don't see a problem. However the reference manual talks about a dual and single CAN Bus architecture with CAN2 being the slave of CAN1. Is it...
can anyone help me to know the reason for this unusual behavior or what am I missing here.
Hi.I want to use my MCU at its max Speed.I am using STM32F103C8T6( Blue Pill ).Can any one Provide good resource?can anyone Provide source code for this ?Can anyone tell me about that in my Controller Why are we using RCC_CFGR and RCC_CFGR2?What is t...
What registers do I look at and what bits? Also, does the peripheral library wrap all the code needed to handle error frames? We are using a board Nucleo-G474RE.This question was already asked at https://community.st.com/s/question/0D50X00009XkhBe/ca...
Dear community,I am totaly new and trying to get some idea on STM32F7...boardI've got opened an example project, provied within IDE. If I compile code and download it to MCU, everything works fine: 2 LEDs are blinking:This is the main code for LEDs b...
Hi!I'm an intern working with STM32L476 MCU. I am new to embedded system coding and was hoping to use a sample code as reference? is there any library where I can access some sample code?
Can you explain me how to trigger NMI in STM32F103 MCU? I am wondering what is the purpose of this interrupt? And Why it is called interrupt because interrupts are trigger by peripheral.Can you show me an example how to trigger it?Thanks so much
I Need to collect the unique IDs of STM32F4 microcontrollers in a single script. so is it possible to connect 2 or more MCUs together and read their unique IDs together?Is it also possible to connect any external Hardware(like Bluetooth...) to STM32F...
@Imen DAHMEN Still looking here for a small-footprint solution in the stm32g4 line with hardware SPI flash (QuadSPI) handling. The WLCSP versions of the STM32G4x3 and STM32G4x4 lines might be viable. They are slated to be released in Q1 2020 (that ...
