From acc276a612d4ea4babf47f8719225eb4a5833036 Mon Sep 17 00:00:00 2001 From: Ken Sarkies Date: Fri, 31 Aug 2012 09:54:31 +0930 Subject: ADC documentation added In adc.h additional defines needed to assist documentation - lines 172-191 added, and 384,436-451 are duplicates of earlier defines to complete parameter sets (compiler has no trouble with these). Minor doc corrections to other files. No code changes (apart from additional defines). --- lib/stm32/dac.c | 4 +- lib/stm32/f1/adc.c | 504 +++++++++++++++++++++++++++++++++++++++++++++++++++- lib/stm32/iwdg.c | 4 +- lib/stm32/nvic.c | 4 +- lib/stm32/systick.c | 4 +- 5 files changed, 511 insertions(+), 9 deletions(-) (limited to 'lib') diff --git a/lib/stm32/dac.c b/lib/stm32/dac.c index 7978059..55440bf 100644 --- a/lib/stm32/dac.c +++ b/lib/stm32/dac.c @@ -1,6 +1,6 @@ -/** @defgroup STM32F-dac-file DAC +/** @defgroup STM32F_dac_file DAC -@ingroup STM32F-files +@ingroup STM32F_files @brief libopencm3 STM32Fxx Digital to Analog Converter diff --git a/lib/stm32/f1/adc.c b/lib/stm32/f1/adc.c index f07164f..6f4de48 100644 --- a/lib/stm32/f1/adc.c +++ b/lib/stm32/f1/adc.c @@ -1,3 +1,70 @@ +/** @defgroup STM32F1xx_adc_file ADC + +@ingroup STM32F1xx + +@brief libopencm3 STM32F1xx Analog to Digital Converters + +@version 1.0.0 + +@author @htmlonly © @endhtmlonly 2009 Edward Cheeseman +@author @htmlonly © @endhtmlonly 2012 Ken Sarkies + +@date 18 August 2012 + +This library supports the A/D Converter Control System in the STM32F1xx series +of ARM Cortex Microcontrollers by ST Microelectronics. + +Devices can have up to three A/D converters each with their own set of registers. +However all the A/D converters share a common clock which is prescaled from the APB2 +clock by default by a minimum factor of 2 to a maximum of 8. + +Each A/D converter has up to 18 channels: +@li On ADC1 the analog channels 16 and 17 are internally connected to the temperature +sensor and VREFINT, respectively. +@li On ADC2 the analog channels 16 and 17 are internally connected to VSS. +@li On ADC3 the analog channels 9, 14, 15, 16 and 17 are internally connected to VSS. + +The conversions can occur as a one-off conversion whereby the process stops once +conversion is complete. The conversions can also be continuous wherein a new +conversion starts immediately the previous conversion has ended. + +Conversion can occur as a single channel conversion or a scan of a group of +channels in either continuous or one-off mode. If more than one channel is converted +in a scan group, DMA must be used to transfer the data as there is only one +result register available. An interrupt can be set to occur at the end of +conversion, which occurs after all channels have been scanned. + +A discontinuous mode allows a subgroup of group of a channels to be converted in +bursts of a given length. + +Injected conversions allow a second group of channels to be converted separately +from the regular group. An interrupt can be set to occur at the end of +conversion, which occurs after all channels have been scanned. + +@section adc_api_ex Basic ADC Handling API. + +Example 1: Simple single channel conversion polled.
