I generated the code using the STM32CubeMx 4.25.FW is 1.8.1
I'm trying to I2C communication between STM32L1(master) and SSD1306 OLED display(slave, 7bit address).
I tested with HAL_I2C_Mem_Write function it is worked fine.
I would like send most data to visualise logo etc. and I would like to using with DMA.
I find function HAL_I2C_Mem_Write_DMA but dostn work.
I visieted examles :
and tried enable Event interrupt and error, but display doesnt work. Dont have Logic analyser for i2c analysis.
Please let me know why HAL_I2C_Mem_Write_DMA() is didn't work.
