experiment for last data lost of I2C DMA transfer

1.to be continued
2.further study on different happen place of I2C DMA EOF interrup
I2C ISR DMA exp to be continued

1.change Addr and first half of initial into while() mode
2.last data break still exists
3.other function will not work in this experimental stage
I2C ISR DMA last data continued

1.get HT TC signal from buffer 1-7
2.tommorow is last day experiment and backup, then continue
dif I2C_RAM and Joystick about I2C using DMA

1.strange bug that Joystick with I2C1-2 wired destroy function of nunchuck
2.find direct reason, refer to 'Joystick I2C bug1.png', pink signal
is SDA of I2C2 it will go down after working
find last bug but main still exists

1.last bug :SDA of I2C2 goes down, because not config RCC I2C2
2.main bug still exists: refer to I2C_RAM_test.png and Joystick_test.png

I2C DMA buffer bugs

1.change I2C_EVENT_MASTER_TRANSMITTER_MODE_SELECTED TO I2C_EVENT_MASTER_TRANSMITTER_MODE_SELECTED..BUG not fix
fix buffer bug

1.only in serial mode
fix DMA bug

1.TC means REM to DR finish, not DR outside finish
