Posted on December 11, 2015 at 22:46Hi,I am working with the I2C HAL code (v1.9.0) and I am playing around with the HAL_I2C_Master_Transmit_IT(), HAL_I2C_MasterTxCpltCallback, HAL_I2C_Master_Receive_IT(), HAL_I2C_MasterRxCpltCallback, HAL_I2C_Mem_Wr...
Posted on January 08, 2016 at 17:15I am attempting to port the ''I2C_TwoBoards_ComDMA'' example project to run on a different target board (ZMDI ZWIR451x Development Board) using Rowley CrossStudio as an IDE. This target has an STM32F103RC micro.Af...
Posted on November 24, 2015 at 17:24Hi, I am working on a project where I am communicating with a capacitive touch sensor via I2C. I have successfully achieved read/write over I2C , and now I would like to use the external device's interrupt line t...
Posted on November 10, 2015 at 12:33Hello, I try to realize a smbus communication where my STM32 is the slave, but I don't understand how to use the different function and interupt. For the moment I managed the reception of the address (with ''HAL_S...
Posted on September 01, 2015 at 00:33 Hello, I'm using MCP3424 and it says in it's datasheet When the Master finds the RDY bit is cleared, it can send a not-acknowledge (NAK) bit and a stop bit to exit the current read operat...
Posted on March 19, 2015 at 13:09 Hello, I am using STM32F0 HAL Drivers to access external EEPROM 24C64 with STM32F The functions I am using areHAL_I2C_Mem_Write/Read but the communication is not always successful. Also it worked while using smd...
Posted on July 29, 2015 at 11:29Hello, I need to make my STM32F072 communicate with a HIH sensor through I2C.I want to use HAL_I2C_Master_Transmit and HAL_I2C_Master_Receive. For exemple if I just need to generate a write condition bit may I use it ...
Posted on June 03, 2015 at 16:58On the STM32F429 Discovery I have managed to boot into the bootloader to upgrade the image in flash via I2C. I still have two issues I (or you) need to solve, however. 1. Flash erase. At first I tried a mass erase of ...
Posted on May 28, 2015 at 20:23I want to enter the Bootloader on STM32F429 Discovery and reprogram the internal flash via I2C. I read AN2606 and then connected the following pins from my I2C master: SDA <-> PB9 SCL <-> PB6 GND <-> GND BOOT0 <-> 3v I...
Posted on May 21, 2015 at 13:08Hello,I'm using the CubeMXF1 Library for the STM32F103 to act as a I2C slave. This slave is usually in Slave Receive Mode. The I2C master is signaled trough a interrupt pin that the slave wants to send something. How c...
