From d5a880807b47188aa5d721f4aff491bc46c6f186 Mon Sep 17 00:00:00 2001 From: flabbergast Date: Tue, 22 Mar 2016 17:51:46 +0000 Subject: [KINETIS] HAL cleanup/update. New entries in kinetis_registry.h to support new MCUs. Moved registers to ext/CMSIS, like it is done for STM32. Move the same drivers to LLD. Add USB driver. --- os/hal/ports/KINETIS/LLD/serial_lld.h | 220 ++++++++++++++++++++++++++++++++++ 1 file changed, 220 insertions(+) create mode 100644 os/hal/ports/KINETIS/LLD/serial_lld.h (limited to 'os/hal/ports/KINETIS/LLD/serial_lld.h') diff --git a/os/hal/ports/KINETIS/LLD/serial_lld.h b/os/hal/ports/KINETIS/LLD/serial_lld.h new file mode 100644 index 0000000..cc66eb3 --- /dev/null +++ b/os/hal/ports/KINETIS/LLD/serial_lld.h @@ -0,0 +1,220 @@ +/* + ChibiOS - Copyright (C) 2013-2015 Fabio Utzig + + Licensed under the Apache License, Version 2.0 (the "License");
