Hi, I want connect an ADC via I2S to the E407 board.
Some I2S pins are connected to SD & USB OTG2. Free are:
I2S2_WS: PB9 -> UEXT 6
I2S2_CK: PB10-> Boot (UART3TX)
I2S2_SD: PC3 -> UEXT 8
and
I2S3_WS: PA4 -> CON4, 3
I2S3_CK: PB3 -> JTAG TDO
I2S3_SD: PB5 -> CON4, 4
Now I use a JLINK, but it connect only in SWD mode.
Can I also use a USB Dongle ST Link V2, with 10 pins? Then the JTAG TDO should be free.
The ST Link V2 has the pins (1..10):
RST,SWCLK, SWIM,SWDIO,GND,GND,3.3V,3.3V,5V,5V
It is possible to connect:
STLINK JTAG
RST 1: RST
SWCLK 9: TCK
GND GND (one of 4,6,..20)
SWDIO 7: TMS
