CC3200:

why those two PIN_18 and PIN_19 has the same name as GPIO_28?

if i want to use those pin as the I/O, how can i init ?

/*LVD_SI GPIO_23 PIN_16 JTAG_TDI
*LCD_SCL GIPO_24 PIN_17 JTAG_TDO
*LCD_RS GPIO_28 PIN_18
*LCD_CS GPIO_31 PIN_45
*LCD_RES GPIO_28 PIN_19 JTAG_TCK

Hi,

Your schematic is wrong. At pin 19 in CC3200 QFN is not GPIO_28. Please see datasheet for CC3200 (table 3-1).

yes,i check the schematic .but it is the demo lauch board that TI had offered.i don't quite understand why this will happen.
there another question ,can the PIN_19 use as the I/O ? i don't see any multi define related about the GPIO.
if i can define as the IO,which it will be ?

Hi,

No pin 19 of CC3200 QFN cannot be used as GPIO pin. It can be used only as JTAG TCK or PWM03.
