I connected the SDA and SCL lines to the corresponding pins on the nucleo which correspond to I2C1. I used Cube to generate the I2C configurations. I know the hardware is setup is correct because it works with my Arduino but I can't get it working with the stm32 nucleo-f446re. ![]() I am using the mbed-studio 1.4.3 with the mbed-os 6.15.1. ![]() BR, Jan MCUExpresso (MCU Expresso) March 4, 2022, 5:42pm 4 Dear Jan, Yes, you are right, wrong P/N. If the hal_i2c module does indeed work with my board, please tell me what I'm doing wrong. Nucleo-F446RE i2c GPIOExpander Keil Studio MbedOS 6.15.1 Check wiring and pull-up resistors. I've also tried using the Mem_Read and Mem_Write functions of HAL but to no avail. For more information on GPIO pins and to check the pinout of Nucleo-F103RB, you can refer to this link. HAL_I2C_Master_Transmit(&hi2c1, ADX元45_ADDR, command_data, 2, 50) 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 tutorial, we will use the STM32F410-Nucleo board, that has the I2C signals on the PB6 and PB8 pins. This module has an I2C slave address of 0x27 as a default address if no solder bridge is touched You can still play around with those bridges to change the. I also tried the same procedure with a custom F103RC board. With a scope, I probed every pin on the board. In fact, you can use the same pin names (A0, A1, etc.) when programming in Mbed. After much trial and error, I took another Mac I had, fresh install of MacOS (10.13.6), fresh install of Arduino (1.8.5), used board manager to get the latest stm32unino (2018.7.2) and tried i2cscanner. Here is the top-left side: You’ll see that the pin assignments is very much like the Arduino UNO. &sharpdefine ADX元45_INIT 0x2D //POWER_CTL Pick a board that has I2C pins exposed and make a note of their numbers and locations. The ST Nucleo F103RB page on the Mbed website contains information about the Arduino header pins of the board. &sharpdefine ADX元45_ADDR 0xA6 //write i2c address since i'm grounding SDO pin This example will initialize the the device, run scan() and then. I connected the SDA and SCL lines to the corresponding pins on the nucleo which correspond to I2C1. import busio from board import i2c busio.I2C(SCL, SDA) print(i2c.scan()) i2c.deinit(). Captive Panel Hardware- Screws, Retainers, Decorative Panel. I know the hardware is setup is correct because it works with my Arduino but I can't get it working with the stm32 nucleo-f446re. ![]() Furthermore, the return for the device id (dev_id) should be a fixed value of 0圎5 according to the ADX元45 datasheet but it is always 0x01. It is returning zeros for the data and the return for the IsDeviceReady is always 0x01 even when I disconnect the SDA and SCL lines. Until yesterday it worked normally I was trying to communicate wit a hcsr04 sensor (ultrasound proximity sensor) with i2c since it was supported and I definitely messed up the pin config (I believe so because thats the only logical explaination). I'm having trouble getting data from the ADX元45 accelerometer. I know HAL should work with all STM32F4xx MCUs but there are no examples for it in the STM32Cube_FW_F4_V1.14.0 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. This is an embedded project for NUCLEO-F446RE board, based on STM32F446RE microcontroller. ![]()
