* `ledcWriteTone()` added a `apbcallback()` evertime the tone value was non zero.
* `addApbChangeCallback()` did not detect duplicate callbacks.
* changed the apbcallback list to a double link to support roll forward, roll back execution. This made the sequences of clock change callback start with the newest registered -> to oldest on the `before` then oldest -> newest after the clock change. This made the UART debug log output have minimal gibberish during the clock change.
* change how the UART callback handled the MUTEX because if any `apbchangeCallback()` executed a `log_x()` a deadlock would occur.
This fixes#3555
* Update esp32-hal-bt.c
BluetoothSerial crash when restart: this is because the BT controller remains in state ESP_BT_CONTROLLER_STATUS_INITED instead of state ESP_BT_CONTROLLER_STATUS_IDLE after the end() method.
in file esp_bt.h it is specified
> @brief Enable BT controller.
> Due to a known issue, you cannot call esp_bt_controller_enable() a second time
> to change the controller mode dynamically. To change controller mode, call
> esp_bt_controller_disable() and then call esp_bt_controller_enable() with the new mode.
after **esp_bt_controller_disable()** the controller remains in state INITED so we do call the **esp_bt_controller_deinit()** function to put the controller into state IDLE.
i have modified the **esp32-hal-bt.c** file
line 57 and next
(i have insert the esp_bt_controller_deinit() function so the controller go into Idle state)
```c++
bool btStop(){
if(esp_bt_controller_get_status() == ESP_BT_CONTROLLER_STATUS_IDLE){
log_i("bt stopped");
return true;
}
if(esp_bt_controller_get_status() == ESP_BT_CONTROLLER_STATUS_ENABLED){
log_i("bt enabled");
if (esp_bt_controller_disable()) {
log_e("BT Disable failed");
return false;
}
while(esp_bt_controller_get_status() == ESP_BT_CONTROLLER_STATUS_ENABLED);
}
if(esp_bt_controller_get_status() == ESP_BT_CONTROLLER_STATUS_INITED){
log_i("inited");
if (esp_bt_controller_deinit()) {
log_e("BT deint failed");
return false;
}
while (esp_bt_controller_get_status() == ESP_BT_CONTROLLER_STATUS_INITED);
return true;
}
log_e("BT Stop failed");
return false;
}
```
* Update esp32-hal-bt.c
remove while to avoid infinite loop
* SPI: Fix discarded-qalifiers warning when compiling with all warnings
This fixes an error introduced with changeset b847f41 which
tightened the use of const for read-only data. The helper
funtion __transferBytes also requires the const qualifier on
outgoing data. Without this change a warning is displayed
when compiling with the Arduino IDE set to display "All"
compiler warnings.
Tests:
- Build an ESP32 SPI sketch that uses static const data to send
to an SPI device using the SPI.transferBytes() API
* SPI:Ensure all local functions are marked static
This audits all functions in the esp32-hal-xpi.c module and
ensures that any functions entirely local to the module are
marked as static.
Tests:
- Build with Arduino set to show all warnings and ensure none
are displayed
* SPI: Remove unused local __spiTranslate24 function
This removes the __spiTranslate24() function which is unused.
* add option to Flush() to only clear txQueue
Add the option to cause Flush() to just wait for tx data to clear the tx fifo and uart, leave the rx queue and rx fifo as is.
* support tx only flush()
* support tx only Flush()
* support txOnly for Flush()
* compatibility to Stream()
* compatibility for Stream()
* default value error
* default value error
* Update esp32-hal-uart.h
* Update esp32-hal-uart.c
* Update HardwareSerial.cpp
* sp
* correctly implement flushTxOnly()
This event name was missing in the list:
d5e2bb12ca/tools/sdk/include/esp32/esp_event_legacy.h (L43)
E.g., it was giving
[D][WiFiGeneric.cpp:337] _eventCallback(): Event: 24 - ETH_GOT_IP
When it should have been
[D][WiFiGeneric.cpp:337] _eventCallback(): Event: 24 - ETH_DISCONNECTED
Especially if the user wants to use the library as component in IDF,
there are some pitfalls while doing make menuconfig. One is this missing
dependency which will now fail with a better error message with a hint to
the user how to fix it.
refs #2154#3215
This changes all SPI functions that take data pointers which are
not modified so that the declaration is const. This allows them
to be used with const data (i.e. held in flash). No functional
changes are required.
The defnitions of spiWrite() and spiTransferBytes() in
esp-hal-spi.h/c have been updated to be consistent.
Tests:
- Build a simple sketch using SPI.writePattern() and
SPI.transferBytes() which uses const data and verify that the
attached device functions as expected.
I compiled the sample "WebServer -> HttpAdvancedAuth". But the right username and password can not login in. I found the file "Webserver.h" may be have some problem. So I fix it. Please check it.
Add a file named `partitions.csv` to your sketch folder and define the partitions inside. In order to not get `Sketch too big`, please select appropriate partition scheme from the board menu
