You shouldn't have to do any of that. You should be able to just define the STEMMA sensor in the config.h and call Feather.measure() to get the data: Config.h:

"{\ 'general':\ {\ 'name':'Device',\ 'instance':1,\ 'interval':2000\ },\ 'components':[\ {\ 'name':'STEMMA',\ 'params':'default'\ }\ ]\ }"

Code:

include

// Include configuration const char* json_config =

include "config.h"

;

// In Tools menu, set: // Internet > Disabled // Sensors > Enabled // Radios > Disabled // Actuators > Disabled // Max > Disabled

using namespace Loom;

Loom::Manager Feather{};

void setup() { Feather.begin_serial(true); Feather.parse_config(json_config); Feather.print_config();

LPrintln("\n ** Setup Complete ** ");

}

void loop() { Feather.measure(); Feather.package(); Feather.display_data(); Feather.pause(); }

Commented out the touchRead() and replaced with

uint16_t Adafruit_seesaw::touchRead(uint8_t pin) {
uint8_t buf[2];
uint8_t counter=0;
uint8_t p = pin;
uint16_t ret = 65535;

do {
  delay(1);
  this->read(SEESAW_TOUCH_BASE, SEESAW_TOUCH_CHANNEL_OFFSET + p, buf, 2,
5000); //increasing the length of the buffer time
ret = ((uint16_t)buf[0] << 8) | buf[1];

counter++;
} while ((ret == 65535) & (counter<3));
return ret;
}
