IWR1642BOOST: GPIO pins on J5 and J6

Part Number: IWR1642BOOST
Other Parts Discussed in Thread: IWR1642

Hi, I need to get 3 GPIO output and 1 GPIO input from the J6 nd J5 connector of the iwr1642 IC.

But I have GPIO 0,1,2. but during the insertion of 0Ohm resisistor the pad is been damaged.I have already used GPIO1 for onw output. GPIO 2 is been used for one input.

how do I get the rest of 2 signlas. when I went through datasheet it gives some adress for each ball. Is it possible to use any of the 2 pins in J5 or J6 connector of IWR1642 IC?

pls help me for this.

Hi,

Table 4.6 of the IWR1642 shows the list of pin and the multiplexing options. As shown on the table there a few other pins that can be muxed as GPIO.

You will need to check the schmatic for the IWR1642BOOST to determine which pins on J1,J2 can be muxed as a GPIO
Determine which of the pin can be used for your application, since you might lose some other peripheral
Make SW modifications to mux GPIOs to the selected pins

Regards,

Charles O

Hi, As you tolds I went through the doc and I found below points and ref images,

J6 has AR_RS232RX AND TX 2 PINS WHICH CAN BE CONFIGURED AS GPIO 15AND 14. AND ADRESS ALSO GIVEN BUT WHERE DO WE PUT THIS ADRESS. COULD YOU PLS GIVE ONE EXAMPLE
