Please ensure the device is correctly connected. Global variables use 1044 bytes (1%) of dynamic memory, leaving 97260 bytes for local variables. I followed them, got the sketch to compile, but I get the error:Īrduino: 1.8.5 (Windows 10), Board: "Nucleo-64, Nucleo F401RE, Mass Storage, Generic Serial, None, Smallest (-Os default)" Archiving built core (caching) in: C:\Users\bjfur\AppData\Local\Temp\arduino_cache_286105\core\core_STM32_stm32_Nucleo_64_pnum_NUCLEO_F401RE,upload_method_MassStorage,xserial_generic,usb_none,opt_osstd_d724efeaa56f34424fff8f97231228d4.a Sketch uses 11064 bytes (2%) of program storage space.

I'm having trouble getting data from the ADX元45 accelerometer.
For more information on GPIO pins and to check the pinout of Nucleo-F103RB, you can refer to this link. If you are using the I2C communication, you have to pull-up the following lines with a proper resistor: I know HAL should work with all STM32F4xx MCUs but there are no examples for it in the STM32CubeFWF4V1.14.0 folder for the nucleo-f446re, and there is no sign of any connection or success when trying to communicate via I2C to a slave device. The following diagrams of different connectors of Nucleo-F103RB board show various GPIO pins for UART, I2C, SPI, ADC, CAN, Timers output, and USB communication. In this way, if you have two sensors on your application board, you can connect them to the same I2C (SDA and SCL) lines, since they will have different I2C addresses. Yes, you can choose the two of them indifferently, by connecting the SDO pin either to GND (resulting in the I2C address 0xD5), or to Vdd (resulting in the I2C address 0xD7).

#NUCLEO F446RE I2C PINS SERIES#
Can I choose indifferent between them and why two type of address? Have I connect any physical pin (Pin 22 SDO) to GND or Vdd? STM32Cube MCU Package for STM32F4 series (HAL, Low-Layer APIs and CMSIS, USB, TCP/IP, File system, RTOS, Graphic - and examples running on ST boards) STM32F446RE.

#NUCLEO F446RE I2C PINS CODE#
I tried your code on my Nucleo with a GPIO expander and it is working. > The acceleration and gyroscope SAD+R/W imu address to read in a register are 0xD5 and 0xD7. I think Nucleo-F443RE and also F433RE do not exist so you probably mean Nucleo-F446RE. Hi me try to answer to your question from the sensor point of view. but im still confused, is there no sign or something which one is pin.0 or pin. For Nucleo F446 the default pins used for Wire instance is PB9/PB8 so setSDA/SCL are not required if you have selected the correct boards (Nucleo64, part num Nucleo F446). my microcontroller is STM32F446RE which means i have 64 configured pin. Thanks for any type of answer and sorry for basic questions. im sorry im still beginner here,so i got confused. ioc file, simply using this function, HAL_I2C_Mem_Read(&hi2c1, IMU_ADD_R1, WHO_AM_I, 1, &check, 1, 1000), where I choose IMU_ADD_R1 0xD5, with the function HAL_UART_Transmit i'm not able to read in the register. In the STM32CubeIDE, with right settings in Pinout & Configuration of. Once you have installed OpenOCD (look here for installation instructions), you can flash the board simply by typing. The easiest way to program the board is to use OpenOCD. This firmware is used to test the communication with the firmware on alwint3r/esp32-ultrasonic-i2c-slave. The ST Nucleo-F446RE board includes an on-board ST-LINK V2 programmer. We'll use the I2C protocol to send and receive messages with a TI. I think my issues start from conneting the module to the mcu. This repository host the firmware for NUCLEO F446RE board that utilizes STM32F446RE microcontroller to read data from an I2C slave. Let's take our STM32 to the next level and communicate with a sensor. Can I choose indifferent between them and why two type of address? Have I connect any physical pin (Pin 22 SDO) to GND or Vdd? The acceleration and gyroscope SAD+R/W imu address to read in a register are 0xD5 and 0xD7. Let's start from reading the default value in the register WHO_AM_I (0x0F) that has to return 104 if the module is detected. I read any kind of articles here in the community but I still can't work it. In this first approach I try to read outputs from MKI159V1 (LSM9DS1) with the nucleo F446RE. Hi, it's my first experience with MCUs in general.
