I'm stuck trying to understand the differences between the two Nucleo-144 boards STM32H743ZI (seems to be the older version but with lots of resources but outdated)andSTM32H743ZI2 (current version but i can hardly find working examples and resour...
Dear TeamWhere the technology was originally invented? about this part: STM32F437IIH6TR
Hi all,I wan to use WKUP pin exit standby mode for low level trigger.I set WKUP pin with low level polarity in HAL_PWR_EnableWakeUpPin() function and pull-up WKUP pin.but the MCU alway wake-up when enter standby mode.When set WKUP pin with high l...
I try to write the driver for I2C and I open the reference I face a problem in setting values for SCLDEL SDADEL SCLH SCLL and I don't know how to set theses values. I kept searching and I saw there is an Excel sheet you can enter the Pclk and I2C spe...
Dear ST Microelectronics Team,I want to connect a STM32F723IE with I2C as master, which is powered with 3.0V, to a bus with one slave with 3.0V and to another slave with 3.8V. From the datasheet I can see that the GPIOs are 5V compliant, but can the ...
Hello,I have custom board. I am working on STM32H7 controller. We use the external crystal of 25Mhz. But when we use that external oscillator using the HSE ,it doesn't provide the clock to controller. Why these happening. Can you please help me
Need your advice. PCB routing. I have Divided signals into 4 groups + (CLK) : 1: Address: SDRAM_BA[0-1]/SDRAM_A[0-11] 2: Command: SDNRAS/SDNCAS/SDNWE 3: Control: NE0/CKE0/NBL[0-1] 4: Data: SDRAM_D[0-7] ( sub goup1 ) & [8-15] ( sub group 2) 5: SD...
