The following commit(s) were added to refs/heads/master by this push: new 42f1790a nimble/drivers/fem: Add support for SKY66403-11 42f1790a is described below commit 42f1790a6ccdb401fa8bfb90f79cf83a7443db44 Author: Szymon Janc <szymon.j...@codecoup.pl> AuthorDate: Fri Jun 9 17:28:47 2023 +0200 nimble/drivers/fem: Add support for SKY66403-11 This adds driver for SKY66403-11. It is very similar to SKY66112-11 but PINs configuration has different meaning in transmit mode. --- .../fem/sky66403/include/sky66403/sky66403.h | 42 +++++ nimble/drivers/fem/sky66403/pkg.yml | 32 ++++ nimble/drivers/fem/sky66403/src/sky66403.c | 201 +++++++++++++++++++++ nimble/drivers/fem/sky66403/syscfg.yml | 76 ++++++++ 4 files changed, 351 insertions(+) diff --git a/nimble/drivers/fem/sky66403/include/sky66403/sky66403.h b/nimble/drivers/fem/sky66403/include/sky66403/sky66403.h new file mode 100644 index 00000000..a9dc99ba --- /dev/null +++ b/nimble/drivers/fem/sky66403/include/sky66403/sky66403.h @@ -0,0 +1,42 @@ +/* + * Licensed to the Apache Software Foundation (ASF) under one + * or more contributor license agreements.
