CC3200 LaunchPad Pins Map

[valerun 1]

 

Hi Rei,

 

while developing an application i took a look at the schematics of the CC3200 LP and noticed that many Pins are not connected to the booster pins and therefore not usable without modifying the Launchpad, or are already in use by system components:

 

P1.3 -> Switch3, Accelerometer INT (detachable from sensors by jumper)

P1.9 -> Yellow LED, SCL (detachable from sensors by jumper)

P1.10 -> Green LED, SDA (detachable from sensors by jumper)

P3.3 -> FTDI_TX

P3.5 + P3.6 are not connected by default

P3.9 -> Red LED

P4.1 - P4.8 are not connected by default

P4.9 -> JTAG_TDO, RS232_RX

P4.10 -> JTAG_TDI, RS232_TX

P2.2 -> JTAG_TCK

P2.8 -> SOP2

P2.9 -> FTDI_RX

P2.10 -> Switch 2

 

regards, Nick

 

 

Hi - I know it's been a bit since this discussion was active but hope you guys can steer me in the right direction. 

 

We want to use Energia to develop an application that will be run on bare CC3200MOD module (just released from TI - http://www.ti.com/product/CC3200MOD/description). The hardware is absolutely awesome and finally is super-easy to integrate into a product since the module just needs power and antenna to work. 

 

Is there such a thing as Energia pin map for that device somewhere. If not, how would one go about interfacing the module in Energia?

 

Thanks!

Val

The pins maps are designed for the LaunchPads supported by Energia. If you're using the MCU alone, you need to dig into its data sheet.

PIN 39 is not working with the following source:

 

#define RELAY_PIN 39

 

void setup() { 

  pinMode(RELAY_PIN, OUTPUT); // initialize the digital pin as an output. 

}

 

void loop() {

  digitalWrite(RELAY_PIN, HIGH); // turn the relay on (HIGH is the voltage level)

  delay(2000);   // wait for a second

  digitalWrite(RELAY_PIN, LOW);   // turn the relay off by making the voltage LOW

  delay(2000);   // wait for a second

}

 

In stead of a pulse signal on PIN 39 the yello led turns on and off.

 

Any sugestions?

Earlier in this thread there is some information from igor:

 

I will try to explain what I meant - but since I haven't studied the data sheet in full detail I am not sure of all the ramifications/limitations/etc.
Unlike some of the other faded pins (which are not connected at all), pins 39 and 40 are connected to pins on the CPU. They are just connected to pins with special functions.
The pins they are connected to are listed with the names ANTSEL1 and ANTSEL2.
They are controlled by GPIO26 and GPIO27.

There is a note saying they are "Connected to enable pin of RF switch. Other usage not recommended."
swru367a, table 16-5

I haven't dug into that, but it it may be better not to use pin 39.
