WebOct 29, 2024 · Gosh darn PORT structs on AVR. To my shock, Atmel has restructured the way they do port addressing in the ATtiny-avr-one series (1616 for example.). I am writing a function that takes in a pin and a port and sets the corresponding pin control variable to have a pullup. The problem is, a PORT struct is defined as follows: WebApr 11, 2024 · From: Ondrej Jirman H6 SoC has a "pio group withstand voltage mode" register (datasheet description), that needs to be used to select either 1.8V or 3.3V I/O mode, based on what voltage is powering the respective pin banks and is thus used for I/O signals. Add support for configuring this register according to the … Webstruct pinctrl_setting *setting) { struct pinctrl_dev *pctldev = setting-> pctldev; int pin; switch (setting-> type) { case PIN_MAP_TYPE_CONFIGS_PIN: pin = pin_get_from_name (pctldev, map-> data. configs. group_or_pin ); if (pin < 0) { dev_err (pctldev-> dev, "could not map pin config for \"%s\"", map-> data. configs. group_or_pin ); return pin; } gute tricks
