Internal pull down value and suggested pull up for i2C
Hi i am using STM32U585 to interface with fuel gauge using i2c. I want to know the internal pull down of ST MCU and if needed what should be the external pull-up resistance value.

Resolved! Error with STM32CubeMx 6.11.1
Hi,I'm working on a STM32H755BIT6 with a custom PCB layout, which uses direct SMPS supply hardware configuration.I'm migrating an existing Keil project which was created with STM32CubeMx 6.7.0 to STM32CubeMx 6.11.1 and I discovered that the option PW...
STM32L051K8 writing half page to EEPROM?
I'm using an STM32L051K8. I'm writing words to EEPROM. It takes a lot of time to do that. I read in the datasheet that it is possible to do a half-page write that will take the same amount of time as a single write. How do I write a half page? Do I u...
Struggling to write on a SD card with the STM32F769I_DISCO
Hello everyone,I have to work on an already existing project using the STM32F769I_DISCO which works properly. My task is to write logs in a file on a SD card. I followed the excellent tutorial by Nicolas Fillon for STMicroelectronics about the matter...
ADC Input protection
I will be using 16 channels of STM32 ADC and I would like to protect them against overvoltage and ESD (those will be used as device inputs and unwanted situations can happen), my initial thought was to use a Zenner diode array and current limiting re...
STM32H743 pwm interrupts with high frequency
Greetings!I generate periodically a 10MHz PWM signal of 8 pulses. The PWM signal has high polarity so the first edge is falling. I need to generate an interrupt/event on the rising edge that'll signal DMA to move data from a GPIO IDR to a data buffer...
Use of 1/3 Bias with a STM32L073V8T6 : VLCD1 and VLCD2 are not at 1/3VLCD and 2/3VLCD
Hello,I am working on a STM32L073V8T6. I want to use the 1/3 bias functionnality to manage a screen.I have configured the contrast control to 3.26V, the Mode to 1/4 Duty Cycle and the Bias Selector to 1/3 Bias. But if I write something to COM0 and...
Standby mode and wakeup issues using wakeup pin
Hi i am working with stm32l051c8t6 , i am using wakeup pin 1 to wakeup from standby mode, weather is that possible to make the wakeup pin should act as wakeup pin and also as external interrupt, it should wakeup when an external interrupt is detected...
Resolved! I2C1 problem in STM32F401 with LSM6DSLTR
Hi,I have custom developed board that uses STM32F401RCT6TR as MCU. I have LSM6DSLTR IMU sensor on the board and MCU is communicating with IMU using I2C1 channel (PB6 and PB7). I also have 2.4" screen (ILI9341) that displays IMU values and external EE...
