From a60ae5044c9d885d6d0152b0907c21977e8a0d6b Mon Sep 17 00:00:00 2001 From: Ken Sarkies Date: Fri, 30 Nov 2012 06:39:57 +1030 Subject: STM32 DMA: replaced F4 header to match that for F2, and move header and source files to common. In the header: - Fix DMA_SxCR_CT: change shift from 18 to 19 For use with the convenience functions: - Added DMA_SxCR_CHSEL generic values - Added DMA_STREAM - generic values - Added dma_if_offset - rather than separating out LISR and HISR - Added masks - Added dma_disable_double_buffer_mode() --- lib/stm32/f2/Makefile | 2 +- lib/stm32/f2/dma.c | 28 ++++++++++++++++++++++++++++ 2 files changed, 29 insertions(+), 1 deletion(-) create mode 100644 lib/stm32/f2/dma.c (limited to 'lib/stm32/f2') diff --git a/lib/stm32/f2/Makefile b/lib/stm32/f2/Makefile index b890fa4..c6a274d 100644 --- a/lib/stm32/f2/Makefile +++ b/lib/stm32/f2/Makefile @@ -30,7 +30,7 @@ CFLAGS = -Os -g -Wall -Wextra -I../../../include -fno-common \ ARFLAGS = rcs OBJS = rcc.o gpio.o usart.o spi.o flash.o \ i2c.o exti2.o timer.o \ - gpio_common_all.o gpio_common_f24.o + gpio_common_all.o gpio_common_f24.o dma_common_f24.o VPATH += ../../usb:../:../../cm3:../common diff --git a/lib/stm32/f2/dma.c b/lib/stm32/f2/dma.c new file mode 100644 index 0000000..8e8f702 --- /dev/null +++ b/lib/stm32/f2/dma.c @@ -0,0 +1,28 @@ +/** @defgroup dma_file DMA + +@ingroup STM32F2xx + +@brief libopencm3 STM32F2xx DMA + +*/ + +/* + * This file is part of the libopencm3 project. + * + * This library is free software: you can redistribute it and/or modify + * it under the terms of the GNU Lesser General Public License as published by + * the Free Software Foundation, either version 3 of the License, or + * (at your option) any later version. + * + * This library is distributed in the hope that it will be useful, + * but WITHOUT ANY WARRANTY; without even the implied warranty of + * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
