Hey everyone, I'm new to these microcontrollers and new to these MCUs in general, and had a few questions... First off, i have some experience using Arduinos, so I'm somewhat familiar with the functionality and programming involved, and I've done all the research I can as far as finding the compatible software for programming, and looking more… (Show more)

Hello, i am using a stm32f427 trough C with IAR compiler, and i am facing a strange situation.   To have a overview, the functionality of the app,  is relaying on 3 ISR's.   Timer1 IRQ handler - runs at 25khz where  some comutation, and update dutycycle registers is performed Timer2 IRQ handler - is used to calculate the rpm of the motor, via… (Show more)

Hello all. I am new to STM paradigm. I have a Nucleo 64 STM32L073RZT6 64 PINS board.   I was trying to configure the Systick timer, however it seems that the input Systick frequency is always divided by 2.   I am using the on-board 8MHz external crystal (which is originally used by the ST-Link interface) but the board marking that I have is… (Show more)

I set up X-CUBE-MCSDK_v5.0.3 from st.com.  MCSDK 5.0.3 is seen as  5.0.2 in About windows. Why?

Hello, I generated the code using the STM32CubeMx 4.25.FW is 1.8.1I'm trying to I2C communication between STM32L1(master) and SSD1306 OLED display(slave, 7bit address).I tested with HAL_I2C_Mem_Write function it is worked fine. I would like send most data to visualise logo etc. and I would like to using with DMA.   I find function … (Show more)

Hi everybody I have designed my own pcb stm8 based on discovery board stm8AF52 5v power I can program it easily without any problem but Vcap voltage is 2.4 instead 1.8  what is the problem here? thanks for your help in advance

If i shake the sensor board, acceleration is produced in the corresponding axis. but if i tap on the board, to produce higher g values, say 200g - 400g, the acceleration spike is seen in all the 3 axis, not just axis which I had tapped.

STM32F722IEK6 customer board, Eclipse Neon 3 Release (4.6.3)   Hello All, I am having a weird problem that the processor/compiler seems not behaving normal. The for-loop delay counter for(m=0; m<1500; m++); running in the Canon_w() routine takes much longer than should be to finish whenever I run the delay loop below at the end of… (Show more)
