* Add the Heltec v4 expansion box. * Change heltec-v4-oled to heltec-v4. * Add touchscreen to I2C scanning. * Add reset and busy pins to the ST7789. * Ignore the touch interrupt pin and extend the sleep time to 1 hour. * Remove the default sleep function. --------- Co-authored-by: Ben Meadors <benmmeadors@gmail.com>
