Photon and the PIN_MAP[] challenge!

Firmware
18

@scruff R
I’m now just trying to get the touch4wire to compile to reduce complexity. When just using this library I get this error: Seems like this is being defined somewhere else not within the libraries?

../../../build/target/user/platform-6/libuser.a(touchscreen.o): In function `setup':
 /spark/compile_service/shared/workspace/6_hal_12_0/firmware-privatouchscreen.cpp:9: multiple definition of `PIN_MAP'
../../../build/target/user/platform-6/libuser.a(Touch_4Wire.o):/spark/compile_service/shared/workspace/6_hal_12_0/firmware-privaTouch_4Wire.cpp:27: first defined here collect2: error: ld returned 1 exit status

Below is the updated macro in the. h file:

#ifndef _ADAFRUIT_TOUCH4WIRE_H_
#define _ADAFRUIT_TOUCH4WIRE_H_

#include "application.h"
#define ADC_MAX_VALUE (0x0FFF)
#define XY_TOLERANCE 15
STM32_Pin_Info* PIN_MAP = HAL_Pin_Map(); // Pointer required for highest access speed
#define pinSetLow(pin) PIN_MAP[pin].gpio_peripheral->BSRRH = PIN_MAP[pin].gpio_pin
#define pinSetHigh(pin) PIN_MAP[pin].gpio_peripheral->BSRRL = PIN_MAP[pin].gpio_pin
#define pinSet(pin, HILO) (HILO) ? pinSetHigh(pin) : pinSetLow(pin)

And here is the .ino file
#include "Touch_4Wire.h"
#define YP A0  // must be an analog pin, use "An" notation!
#define XM A1  // must be an analog pin, use "An" notation!
#define YM D0  // can be a digital pin
#define XP D1  // can be a digital pin

TouchScreen ts = TouchScreen(XP, YP, XM, YM, 300);

void setup(void) {
 // Serial.begin(9600);
}

void loop(void) {
  TSPoint p = ts.getPoint();

  if (p.z > ts.pressureThreshhold) {
     Serial.print("X = "); Serial.print(p.x);
     Serial.print("\tY = "); Serial.print(p.y);
     Serial.print("\tPressure = "); Serial.println(p.z);
  }

  delay(100);
}

Edited by ScruffR: I’ve reformatted your code sections (have a look at “Forum Tips and Tricks” to see how to do that)
