I2C passiv Mode possible?

Hi,I try to sniff a I2C communication between multiple devices with my STM32G473.The controller should only listen passiv. Is this possible?For sure, I can always set the NACK-Bit to prevent sending an ACK and disable the Clock-stretching.And I can u...

Serial Numbers at production

Hi,im looking for some advice for using serial numbers at production. Its for a STM32H747 and we don't have NFC or BLis it normal practice to use your own serial numbers or use the MCU built in one?if using your own, at production whats a good way to...

What will be the maximum time delay that we can give 16 bit and 32 bit timer in stm32f407vgt6. For both what will be prescaler ,counter period and frequency oscillator value.And why that only value?

UART LOOP using registers

Hi ! This is me again !I am able to send and receive separately but when try to do the loop, it doesnt work. What I am basically doing is when the full reception interrupt is set, I enable the transmission and as soon as the transmission is done, I d...

stm32g474 hrtimer issue

I meet a confused and unresonable issue about hrtimer with stm32g474mbt6.condition: 1).use timerA to generate 2 channel pwm. Channel 1 is set by CMP1, reset by CMP2; Channel 2 is set by CMP3, reset by CMP4;2). enable preload function, update when res...

Is it possible to to use same ADC in STM32 to sample at two different frequency simultaneously??

I have one ADC, whose channel 1 to 4 will start conversion at x time and channel 5 to 8 will start conversion at y time. May I know how to use the same ADC in an STM32 microcontroller to sample at different frequencies for different channels??

Safe clock speeds

I'm looking for information that will tell me the safe clock speeds for a voltage range. For example from 1.8v to 2.5v what is the highest clock speed I can run safely. usually there is a figure in the datasheet, but I can't find it. I'm using a ...

i am sanding data too my serial monitor to uart2 and uart to data transmit and received and transmit to uart6 and uart 6 received and and transmit back my serial monitor plz help i am working stm32f411vet6 microcontroler

I2C slave address masks interferes with slave addresses 0-7

Unfortunately, I cannot post any code for this question but I believe it relates more to the HAL library and the i2c address matching hardware of the STM32 microcontrollers.I am working on emulating multiple I2C slaves in the address range of 1-24 on...
