A byte is transferred at 111 kHz rate. You can use standard polling, interrupt or DMA interface. If the device you want to communicate with stretches the clock to slow down transfers, then your forced DMA will not work. the h-zoneWebHAL_BUSY means either the peripheral isn't ready because you're using it somewhere else, or the line is busy. If it's the former, fix your code. If it's the latter, a device may be holding down the SCL line, or the STM32 I2C peripheral is just in a bad state.
