This updates lib/cmsis-svd, pulling in the updates to the Espressif SVD
files here:
https://github.com/cmsis-svd/cmsis-svd-data/pull/3
This is needed for wifi/BLE support on the ESP32-C3 (the older SVD files
were missing some necessary interrupts).
I managed to get CGo sort-of working in VSCode (meaning that it will
typecheck code in the IDE itself) using a few crude hacks, but it
requires a few minor changes to the TinyGo standard library.
I intend to eventually add this support in the TinyGo extension for
VSCode directly, but for now I've manually updated .vscode/settings.json
to get IDE support. In any case, it would be nice to have this for when
I hopefully add this to the TinyGo extension eventually.
The IsZero function was changed slightly in Go 1.22, so we'll need to
update it.
While this could in theory break existing programs that rely on the old
behavior, they'd also break with the imminent Go 1.22 release so I don't
think this is a real problem.
This function is needed for Go 1.22, and is used from various packages
like math/rand.
When there is no random number generator available, it falls back to a
static sequence of numbers. I think this is fine, because as far as I
can see it is only used for non-cryptographic needs.
A few non-generic functions like HashStrBytes have been kept for
backwards compatibility, so this package should continue to work with
older Go versions (as long as they support generics).
The right-hand grove port on the wioterminal can be used as UART, using
D0/D1 pins. The pins D0/D1 are tied to SERCOM4, so this patch exposes a
UART4 for sercom4 access.
RX = A0/D0 = PB08/SERCOM4.0 (port 4 pad 0)
TX = A1/D1 = PB09/SERCOM4.1 (port 4 pad 1)
Tested with Lora E5 UART.
uart : = machine.UART4
tx := machine.D0
rx := machine.D1
Note: must also cross Tx/Rx wires in grove cable. See

* stub out more types/funcs to compile against golang.org/x/net/internal/socket
These are changes need to compile github.com/domainr/dnsr/ with TinyGo.
See issue https://github.com/tinygo-org/net/issues/14.
These change are mostly to fix missing symbols in src/crypto/tls and
src/net. Missing types and functions are cut-and-pasted from go1.21.4.
Functions are stubbed out returning errors.New("not implemented").
DNRS is compiled by running tinygo test:
sfeldma@nuc:~/work/dnsr$ tinygo test -target=wasi
With this patch, and a corresponding patch for tinygo-org/net to fixup
src/net, you should get a clean compile.
This PR adds a network device driver model called netdev. There will be a companion PR for TinyGo drivers to update the netdev drivers and network examples. This PR covers the core "net" package.
An RFC for the work is here: #tinygo-org/drivers#487. Some things have changed from the RFC, but nothing major.
The "net" package is a partial port of Go's "net" package, version 1.19.3. The src/net/README file has details on what is modified from Go's "net" package.
Most "net" features are working as they would in normal Go. TCP/UDP/TLS protocol support is there. As well as HTTP client and server support. Standard Go network packages such as golang.org/x/net/websockets and Paho MQTT client work as-is. Other packages are likely to work as-is.
Testing results are here (https://docs.google.com/spreadsheets/d/e/2PACX-1vT0cCjBvwXf9HJf6aJV2Sw198F2ief02gmbMV0sQocKT4y4RpfKv3dh6Jyew8lQW64FouZ8GwA2yjxI/pubhtml?gid=1013173032&single=true).
