shared/tinyusb/mp_usbd_cdc: Rewrite USB CDC TX loop.
...
This is related to the previous commit (where due to the new config flag
this loop could end up stuck indefinitely if the USB host was
disconnected). The previous loop could maybe still get stuck if the
low-level USB state and the high-level USB state got out of sync. (Not
clearly possible, but hard to say definitely not possible.)
To be "belts and braces" careful:
- Always run mp_usbd_task() each time around the loop to progress the
state.
- Always evaluate the timeout if we fail to write anything to the FIFO.

shared/tinyusb: Fix hang from new tx_overwritabe_if_not_connected flag.
...
This flag is in the main branch of TinyUSB, included in Espressif since
their v0.18.0~3 component release (but it's not actually in TinyUSB v0.18.0
release).
Setting the flag is needed for the USB device not to block waiting for
space in the FIFO if the host is disconnected.

esp32: Add IDF Component Lockfiles to git repo.
...
This is recommended by Espressif, and it's the only way to ensure
everyone builds the same set of component versions.
The awkward part is that updating the ESP-IDF version will churn a line
in each of these files (and possibly other changes).
Adds a build-time check for lock file changes, which is either a warning or
a hard error depending on the value of MICROPY_MAINTAINER_BUILD
flag (introduced in previous commit).

Also future-proofs this code for other chips. Apart form C6 and C2, all
currently supported chips use APB clock for GPTIMER_CLK_SRC_DEFAULT.
ESP32-C2 uses 40MHz PLL but APB_CLK_FREQ was 26MHz.
ESP32-C6 uses 80MHz PLL but APB_CLK_FREQ was 40MHz.
Implementation now gets the correct frequency from ESP-IDF.

I2CTarget costs about 8k of flash size on ESP32-S2, and about 11k on

extmod/machine_i2c_target: Add new machine.I2CTarget class.
...
This commit implements a generic I2C target/peripheral/"slave" device,
called `machine.I2CTarget`. It can work in two separate modes:
- A general device with interrupts/events/callbacks for low-level I2C
operations like address match, read request and stop.
- A memory device that allows reading/writing a specific region of memory
(or "registers") on the target I2C device.
To make a memory device is very simple:
from machine import I2CTarget
mem = bytearray(8)
i2c = I2CTarget(addr=67, mem=mem)
That's all that's needed to start the I2C target. From then on it will
respond to any I2C controller on the bus, allowing reads and writes to the
mem bytearray.
It's also possible to register to receive events. For example to be
notified when the memory is read/written:
from machine import I2CTarget
def irq_handler(i2c_target):
flags = i2c_target.irq().flags()
if flags & I2CTarget.IRQ_END_READ:
print("controller read target at addr", i2c_target.memaddr)
if flags & I2CTarget.IRQ_END_WRITE:
print("controller wrote target at addr", i2c_target.memaddr)
mem = bytearray(8)
i2c = I2CTarget(addr=67, mem=mem)
i2c.irq(irq_handler)
Instead of a memory device, an arbitrary I2C device can be implemented
using all the events (see docs).
This is based on the discussion in #3935 .

tools/mpremote: Update ESPxxx detection for USB-CDC ports.
...
Detection of ESP-XX devices was based on just the names of the USB driver
name, and did not account for the switch of the newer ESP-xx devices to
USB-CDC. On Windows this caused unwanted/unneeded resets as the DTR/RTS
signals are also used for automatic device reset over USB-CDC. See
https://github.com/micropython/micropython/issues/9659#issuecomment-3124704572
This commit uses the Espressif registered VID 0x303A to detect USB-CDC
ports, to enable the same DTR/RTS settings as used on the UART-USB
connection.
Also improved the robustness of the code using `getattr()`.
