RFC4648 specifies an alternate alphabet for base64 encoding / decoding
where '+' and '/' are exchanged for '-' and '-' to make the resulting
string safe to use in filenames and URLs.
This adds a base64url_encode() function that uses the alternate alphabet.
The base64_decode() function is extended to accept both alphabets.
This adds a driver for the SPI based AT86RF215 transceiver.
The chip supports the IEEE Std 802.15.4-2015 and IEEE Std 802.15.4g-2012 standard.
This driver supports two versions of the chip:
- AT86RF215: dual sub-GHz & 2.4 GHz radio & baseband
- AT86RF215M: sub-GHz radio & baseband only
Both radios support the following PHY modes:
- MR-FSK
- MR-OFDM
- MR-O-QPKS
- O-QPSK (legacy)
The driver currently only implements support for legacy O-QPSK.
To use both interfaces, add
GNRC_NETIF_NUMOF := 2
to your Makefile.
The transceiver is able to send frames of up to 2047 bytes according to
IEEE 802.15.4g-2012 when operating in non-legacy mode.
Known issues:
- [ ] dBm setting values are bogus
- [ ] Channel spacing for sub-GHz MR-O-QPSK might be wrong
- [ ] TX/RX stress test will lock up the driver on openmote-b
Declaring all auto_init_% modules as pseudomodules will allow
using auto_init_% modules as modules that can be disabled. This
will give a higher lever of granularity allowing users to not
disable the complete auto_init module but only some of them.
This implements a client for DHCPv6 IA_PD (Identity Association for
Prefix Delegation). Goal was to have a IETF-compliant alternative to
UHCP. The implementation was based on RFC 8415.
Having the definitions sit in the `net/gnrc/sixlowpan/frag.h` header
does not make much sense, when using Selective Fragment Forwarding
(and the fragmentation buffer already includes a
`net/gnrc/sixlowpan/frag/stats.h` header), so they are moved to their
own header. Since with this change it makes more sense to have the
statistics stored in their own sub-module, the pseudo-module is also
actualized.
The INA219 has the exact same interface as the INA220 (including values and
semantics of the configuration register). Thus, this driver can be used for
both. The ina220 has been renamed to ina2xx to reflect this and pseudo modules
for the ina220 and ina219 have been added.
Added driver for the WS2812/SK6812 RGB LEDs often sold as NeoPixels, which due
to their integrated RGB controller can be chained to arbitrary length and
controlled with a single GPIO.
The ATmega128RFA1 and ATmega256RFR2 contain a version of this IP
on the MCU.
The radio core behaves mostly like a at86rf231, but all registers
are mapped to memory and radio states can directly generate interrupts
on the CPU.
The ATmega256RFR2 adds support for automatic retransmissions.
This has not been implemented yet.
