HAL_I2C_Master_Transmit_IT error in the Hal lib?

I am using the HAL library generated with the STM32CUbeIDE for controlling a I2C sensor.With the demoboard nucleo stm32l031k6I am using the HAL interrupt master transmit functionbut the byte’s send aren't the ones that I attach.While debugging I see ...

I2C Slave “Repeated Start�? Callback?

STM32F105, HCLK=72MHz, HAL Ver 1.1.8.0, SCL = 100KHzIs there a “Repeated Start�? HAL callback? I couldn’t find any direct reference but does the STM32 I2C peripheral know when this occurs and set a status bit somewhere?In my application, I can’t allo...

HAL_I2C_Master_Transmit_DMA sends only a START and leave both I2C lines in low state.

I'm trying to send and receive data to and from a BH1750 and the microcontroler (NUCLEO-F446RE / STM32F446RE) onlyh sends a START when using the function HAL_I2C_Master_Transmit_DMA.I used a logic analyser to try to see whats is going on (picture att...

No rule to make target

Hi, All I am new to use STM IC. have the following question. please help.1) Nucleo-c0316C, cubeIde Version: 1.12.12) import CubeIDE example I2C_TwoBoards_AdvComIT. that worked fine3) changed the I2C address from 0x3E to 0x78 build all. then 13:20:5...

Resolved! How to access mutexes and semaphores generated by STM32CubeIDE FreeRTOS integration from another file?

I'm using a mutex to share the I2C bus between an OLED display and an EEPROM. I'm using the IDE to generate the FreeRTOS configuration and tasks initialization (freertos.c file). I have an external file where all the LCD writing occurs. How could I a...

Resolved! STM32_I2C_BMP_280

Hello Everyone, I am trying to interface BMP280 sensor using I2C with STM32F401 Discovery Board. My code gets compiled without any error and i have declared two global variable, Temperature and Pressure . when i debug using ST Link GDB sever I cannot...

Resolved! STM32CubeIDE HAL_I2C_ErrorCallback function does not work.

I'm using i2c interface to communicate with a eeprom memory, by dma. It's working, however, when I put a wrong address to write in the memory (to test the errors), I get as return HAL_ERROR, but the function HAL_I2C_ErrorCallback (that i implemented)...

First project with Nucleo-F401RE. Trying to interface to a ***-45. Regardless of what I do I get multiple HAL errors.

Static Constant Variable Allocated as RAM when used by HAL I2C functions STM32CubeIDE

Hi, I am working on a project where I have a 4096 byte data array that I will be passing to another component via I2C. This array is a constant, so I declared it as follows in order to have it live in flash memory rather than RAM:static const uint8_t...

Resolved! How would you go about adding the version and 8 characters of the git hash to the hexfile name so we can also access it in the program?

Say we have a STM32 project called Foo. When it is compiled, it generates an intel hex file called Foo.hex that we can use to upgrade the file in the field. That is easy. What we would like to do as add the version say 10.1 or 10_1 and the last 8 di...
