STM32F302RBT...I want to use OpAmp1 in PGA Connected mode feeding ADC1 IN3. According to CubeMX the OpAmp pins VINP, OPAMP_VOUT and VINM are all 'Used' even though VOUT is internally connected to the ADC and VINM is not being used.If in the cube I ch...
Dear All,I have some problem with the STOP mode 2, doesn't work! In my program I use the following periphals:I2CSAILPUARTUART2My microcalculator is the STM32L4R5ZIT, and I use the nucleo EVAL board.To go in the STOP mode 2 I use the following command...
Hello,I see that MDMA is limited to 128 bytes (BufferTransferLength).Yet, when using DMA (with HAL_SRAM_Read_DMA for example) we can use larger size (up to 65536).Yet, I don't see in code that DMA is triggered more than once.Is it that these multiple...
Hello, i am very new to microchip stuff. I want to connect 13 laser sensors to STM32, any advice on how should i do it? I've been reading and asking around, and i read about expansion boards and serial expansion boards. Can anyone give me an advice a...
Is the calculation procedure in AN2867 "Oscillator design guide for STM8AF/AL/S and STM32 microcontrollers" correct? On page 12, Cl is given byCL = (CL1 x CL2)/(CL1 + CL2) + Cowhere CL1 and CL2 are loading capacitors and Co is the crystal shunt c...
hii have a problem when i generate a code by cubemx v5 ,i have a problem for my stm32h7 board.mcu wait at this line and can't init voltage regulator well, and wait on this infinity loop./** * @brief System Clock Configuration * @retval None */ ...
Please excuse my question as I am sure it has been asked before. I am a bit new to ST microelectronics. I am suing the nucleo-f767. I noticed that on my windows device manager there is STMicroelectronics STLink Virtual COM Port. I would like to u...

I need to interface ILE9341V TFT display with STM32F030C6 MCU.My project hardware has only 3 wires (CSX, SDA and SCL) from the display side.By referring the TFT display's datasheet, I found that I have to use 3-wire 9-bit mode only (to be compatible ...
I'm laying out a board using a STM32F103CB and I'm connecting to an I2C peripheral, and I noticed that on the STM32 there's a third I2C pin, labelled SMBAI - what is this pin, I'm unfamiliar. Is this an address pin for the STM32 for slave option? I c...
