ESP32-S3 defines two additional general use pins in
ports/espressif/peripherals/esp32s3/pins.h, for which
support is missing in the microcontroller module HAL.
This prevents running into the pins that cannot be reset. On 1011
it was off by one pin that isn't attached to the package. So,
having the USB pins forbidden prevented resetting to a NULL address.
Fixes#7952
esp_ping_new_session can fail, particularly if ping is called quickly
many times in succession.
This is because `esp_ping_new_session` has to do a bunch of stuff
including creating a task and a socket. Calling `esp_ping_delete_session`
doesn't clean up these resources immediately. Instead, it signals the
task to clean up resources and exit 'soon', but 'soon' is defined as 1
second.
When the calls are frequent, the in-use sockets and tasks fill up
available slots—I didn't actually check which resource gets used
up first.
With this change, the ping call will raise an exception instead of
continuing with a call to esp_ping_start that crashes.
Closes#5980 based on my testing on an ESP32S3-N8R2.
The internal flash cache wasn't being properly used, because
`write_blocks` unconditionally performed the flash write.
Fixing this so that the write's not done until `internal_flash_flush`
fixes the problem in my test program with i2sout & synthio.
as a future optimization, `flash_read_blocks` could learn to read out
of the cache, but that's probably not super important.
This class allows much more expressive sound synthesis:
* tremolo & vibrato
* arbitrary frequency
* different evelope & waveform per note
* all properties dynamically settable from Python code
This adds a script to generate the peripherals files (except clock).
It adds support for the 1015, 1020, 1040, and 1050 EVKs.
Some work was started on 1176 but it isn't working. So, the board
def is in a separate branch.
Fixes#3521. Fixes#2477.
