Global ADC_ATTENUATION_11_DB

ADC_ATTENUATION_11_DB is deprecated, use ADC_ATTENUATION_12_DB instead.

Global coap_build_hdr (coap_udp_hdr_t *hdr, unsigned type, const void *token, size_t token_len, unsigned code, uint16_t id)

Use coap_build_udp_hdr instead

Global coap_hdr_data_ptr (const coap_udp_hdr_t *hdr)

Use coap_get_token() instead

Global coap_hdr_get_token (const coap_udp_hdr_t *hdr)

This function was introduced to keep legacy code alive. Introducing new callers should be avoided. In the RX path an coap_pkt_t will be available, so that you can call coap_get_token instead. In the TX path the token was added by us, so we really should know.

Global coap_hdr_get_token_len (const coap_udp_hdr_t *hdr)

This function was introduced to keep legacy code alive. Introducing new callers should be avoided. In the RX path an coap_pkt_t will be available, so that you can call coap_get_token instead. In the TX path the token was added by us, so we really should know.

Global coap_hdr_len (const coap_udp_hdr_t *hdr)

This function was introduced to keep legacy code alive. Introducing new callers should be avoided. In the RX path an coap_pkt_t will be available, so that you can call coap_get_total_hdr_len instead. In the TX path the header was created by us (e.g. using coap_build_hdr which returns the header size), so we really should know already.

Global coap_hdr_set_code (coap_udp_hdr_t *hdr, uint8_t code)

Use coap_pkt_set_code instead

Global coap_hdr_set_type (coap_udp_hdr_t *hdr, unsigned type)

Use coap_pkt_set_type instead

Global coap_hdr_t

Avoid using low level types in your application, but rather use the zero overhead wrappers and work on coap_pkt_t instead.

Global coap_hdr_tkl_ext_len (const coap_udp_hdr_t *hdr)

Use coap_pkt_tkl_ext_len instead.

Global coap_parse (coap_pkt_t *pkt, uint8_t *buf, size_t len)

Use coap_parse_udp instead

Global coap_pkt_t::hdr

Use coap_pkt_t::buf to access the underlying buffer. Use helpers such as coap_get_code_raw to parse the contents in a transport agnostic way.

Global CONFIG_GNRC_IPV6_STATIC_LLADDR_IS_FIXED

Will be removed after release 2025.07 - after this the static link-local address will always be fixed unless a use-case for the auto-increment can be found.

Global gcoap_request_memo_get_hdr (const gcoap_request_memo_t *memo)

Use gcoap_request_memo_get_buf instead

Global GNRC_NETTYPE_LORAWAN

LoRaWAN payloads do not have a special type anymore and just use GNRC_NETTYPE_UNDEF. Will be removed after 2024.10 release.

Module net_gnrc_nettype_lorawan

LoRaWAN payloads do not have a special type anymore and just use GNRC_NETTYPE_UNDEF. There is no module needed for that. This module will be removed after 2024.10 release.

Global NETDEV_EVENT_TX_COMPLETE_DATA_PENDING

Issue an NETDEV_EVENT_TX_COMPLETE event instead and pass the data pending info in netdev_driver_t::confirm_send via the info parameter

Global NETDEV_EVENT_TX_MEDIUM_BUSY

Issue an NETDEV_EVENT_TX_COMPLETE event instead and return -EBUSY in netdev_driver_t::confirm_send.

Global NETDEV_EVENT_TX_NOACK

Issue an NETDEV_EVENT_TX_COMPLETE event instead and return -EHOSTUNREACH in netdev_driver_t::confirm_send. Via the info parameter additional details about the error can be passed

Global netdev_ieee802154_dst_filter (netdev_ieee802154_t *dev, const uint8_t *mhr)

This function is currently deprecated and will be removed after Release 2022.01. Use ieee802154_dst_filter instead.

Global pcf857x_error_codes_t

These are aliases for errno error codes now, use them directly

Module pseudomodule_sema_deprecated

Will be removed after 2021.07 release.

Global RIOT_FILE_NOPATH

This macro will be removed after the 2025.10 release. Use the compiler builtin __FILE_NAME__ instead (GCC 12+, clang 9+)

Global RIOT_FILE_RELATIVE

This macro will be removed after the 2025.10 release. Use the compiler builtin __FILE__ instead (GCC 8+, clang 10+)

Global RIOT_MCU

Use RIOT_CPU instead. This will be removed soonest in release 2025.04

Global saul_class_to_str (const uint8_t class_id)

Use saul_class_print or saul_class_write instead

Global sema_wait_timed (sema_t *sema, uint64_t timeout)

Will be removed after release 2021.07

Global SPIClass::setBitOrder (uint8_t order)

This function is deprecated in the official Arduino API, so it is a good idea to not use it. In RIOT, this function is not yet scheduled for removal to allow using Arduino libraries using it.

Global SPIClass::setClockDivider (uint8_t divider)

This function is deprecated in the official Arduino API, so it is a good idea to not use it. In RIOT, this function is not yet scheduled for removal to allow using Arduino libraries using it.

Global SPIClass::setDataMode (uint8_t mode)

This function is deprecated in the official Arduino API, so it is a good idea to not use it. In RIOT, this function is not yet scheduled for removal to allow using Arduino libraries using it.

Module sys_xtimer

xtimer has been deprecated in favor of the ztimer high level timer abstraction layer

Global THREAD_CREATE_STACKTEST

will be removed after 2025.07 release

Global UNIT_G

, use UNIT_G_FORCE instead

Global UNIT_GR

, use UNIT_GRAM instead

Global UNIT_GS

, use UNIT_GAUSS instead

Global xtimer_nanosleep (uint32_t nanoseconds)

This function is deprecated as no XTIMER backend is currently configured to run at more than 1 MHz, making nanoseconds accuracy impossible to achieve.
