It is developing products using stm32f469i_Discovery.The stm32f469i_Discovery board is intended to be used with DS3231.It was connected to I2C1 for I2C communication.I2C1 initialization runs on MX_I2C1_Init();In this function, It is developing produc...
Hi All,I'm using an NUCLEO-F103RB with STM32F103RBBasically when I run the code or debug the CODE with the IDE every works fine.But if unplugged the STM from the computer and plug it again the code stays stuck.After the power supply reset is getting ...
Hello,i want to measure time between high and low pulse from a ultrasonic sensor. The time is set to 1ms. It works until i reach the end of the time ARR. To differentitat betwenn a distance like 1cm and 11cm (10cm end of the counter) i have to count...
I used an LSE component proven out on another design containing a STM32F412 for a new design using a STM32L433. The LSE part is Abracon ABS06-32.768kHz-6 which is listed in AN2867 as compatible with the L4 family. I'm using the HAL_RCCEx_EnableLSCO()...
I am having trouble getting the ADC to work right in basic polled operation. I am polling two channels which provide voltages via resistor dividers. I have measured the voltages at the ADC inputs and they are correct so I do not believe the divider i...

In RM0091, A.7.2 ADC enable sequence code example:ADC1->ISR |= ADC_CR_ADRDY; /* (2) */However, there is no ADC_CR_ADRDY, it is supposed to be ADC_ISR_ADRDY.Also, examples should not show the bad practice using RMW to clear rc_w1 status bits, so this ...
One user mentions noise from USBhttps://community.st.com/s/question/0D50X00009XkfMDSAZ/stm32f4-adc-noise-with-increased-activity-in-usb-fsOther comments:Keep the wiring short, and make sure the resistor value matches the ADC input impedance. I’ve suc...
I have been using STM32G MCUs with USB PD Sink or Source application. Right now, I want to implement Debug Accessory Mode in either STM32G0 or G4 MCUs with SInk USB PD Application. Hence, i would like to use USB-C cable SBU and Data lines for MCU fla...
I am a newbie here. I have purchased a STM32G071 Nucleo-64 development board. I wish to interface it to the 5 volts signal(s). The intended interface pins are PB1, PB3 and PB4. The Absolute Maximum ratings VIN states:- 1) Input voltage on FT_xx pins ...
