esphome with esp32s6 UART presents errors

[mx5gr]

As only ESP-IDF framework is supported by ESP32-C6, we defined the following esphome (2024.6.4) config:

`

When we tried to compile it, we get:

[mx5gr]

I managed to compile the component by making the following alterations..

Within the climate/daikin_s21_climate.cpp file, find/replace:

void DaikinS21Climate::dump_config() {
ESP_LOGCONFIG(TAG, "DaikinS21Climate:");
ESP_LOGCONFIG(TAG, " Update interval: %lx", this->get_update_interval());

(Note: %u becomes %lx)

Within the same file, three more conditions (Disabled/Fan/Dry) are added to the following:

void DaikinS21Climate::save_setpoint(float value) {
auto mode = this->s21->get_climate_mode();
optional prev = this->load_setpoint(mode);
// Only save if value is diff from what's already saved.
if (abs(value - prev.value_or(0.0)) >= SETPOINT_STEP) {
switch (mode) {
case DaikinClimateMode::Auto:
this->save_setpoint(value, this->auto_setpoint_pref);
break;
case DaikinClimateMode::Cool:
this->save_setpoint(value, this->cool_setpoint_pref);
break;
case DaikinClimateMode::Heat:
this->save_setpoint(value, this->heat_setpoint_pref);
break;
case DaikinClimateMode::Dry:
//this->save_setpoint(value, this->heat_setpoint_pref);
break;
case DaikinClimateMode::Fan:
//this->save_setpoint(value, this->heat_setpoint_pref);
break;
case DaikinClimateMode::Disabled:
//this->save_setpoint(value, this->heat_setpoint_pref);
break;
}
}
}

optional DaikinS21Climate::load_setpoint(DaikinClimateMode mode) {
optional loaded;
switch (this->s21->get_climate_mode()) {
case DaikinClimateMode::Auto:
loaded = this->load_setpoint(this->auto_setpoint_pref);
break;
case DaikinClimateMode::Cool:
loaded = this->load_setpoint(this->cool_setpoint_pref);
break;
case DaikinClimateMode::Heat:
loaded = this->load_setpoint(this->heat_setpoint_pref);
break;
case DaikinClimateMode::Dry:
//loaded = this->load_setpoint(this->heat_setpoint_pref);
break;
case DaikinClimateMode::Fan:
//loaded = this->load_setpoint(this->heat_setpoint_pref);
break;
case DaikinClimateMode::Disabled:
//loaded = this->load_setpoint(this->heat_setpoint_pref);
break;
}
return loaded;
}

Furthermore, within the s21.cpp file, find & replace the following:

void DaikinS21::check_uart_settings() {
for (auto uart : {this->tx_uart, this->rx_uart}) {
if (uart->get_baud_rate() != S21_BAUD_RATE) {
ESP_LOGE(
TAG,
" Invalid baud_rate: Integration requested baud_rate %u but you "
"have %lx!",
S21_BAUD_RATE, uart->get_baud_rate());

and

void DaikinS21::dump_config() {
ESP_LOGCONFIG(TAG, "DaikinS21:");
ESP_LOGCONFIG(TAG, " Update interval: %lx", this->get_update_interval());
this->check_uart_settings();
}

(Note: %u becomes %lx)
