Dear ST Community,I do have a doubt regarding an I2C communication between my STM32L031K6Tx that is the slave and powered with VDD=3V3 and a host that is powered with 1V8. Pull-up resistors are connected to 1V8 (host side).I did a functional test and...
I am using the STM32F407Zg MCU and is learning how to set up the ADC for continuous sampling by timer. But I have trouble to understand the manual. The ADC section refer to TIM1_CH1 or TIM1_CC1 etc. But the Timer section do not use the same term.
Hi,I am using STM32F107VCT6 MCU and i need to measure voltage at GPIO PB11.But there is no any ADC channel connected to this GPIO but i see that this GPIO cab be used as ADC1_EXTI11/ADC2_EXTI11.So with this Alternate function of GPIO can we measure v...
I have an STM32L476 Nucleo-64 development board and I wish to do USB-development (simple Virtual Com Port) completely unrelated to the USB-connector that the ST-LINK Utility communicates via. I understand I need to connect ground, USB_OTG_FS_DP (PA12...
I use BMP280 sensor with STM32F446. When i upload my code for bmp280 i am not getting data from serial display. How can i fix it? What is the problem?I have added the codes I used below.
Basic project with the defaults from the config wizard for STM32L4S7Add into the main while loop: declared_volatile_variable += 1; HAL_Delay(1000);Set a break point on the addition and debug. Every second, the breakpoint triggers, then continue...
Posted on February 19, 2018 at 14:48I'm using a stm32f407vg board. Suddenly I can't download my code to flash memory anymore. I'm using the keil toolchain. I tried stm32 st-link utility, but it can't connect to target either. I tried the option 'con...
Hello, I am trying to get my I2C code Master working. I don't have the slave device connected and I am trying to see the output on a logic analyzer. I have connected the SCL and SDA pins to breadboard to a 2k pull up of 3.3V and the board is running ...
