Many stm32 families have multiple ADC and DAC peripherals. F0 (so far) only
has one. To make it easier to use the same code on many stm32 families,
provide an alias for ADC1 to ADC.
After adding support to the f3, add missing doxygen support to the f0
equivalent. This improves things and keeps them consistent until/if they are
pulled out as common code.
Based on the f0 support, which has identical functionality, but with doxygen
added. Bits renamed as they are only HSE prediv on some targets, and makes
things more consistent with the f0.
Fixes part of github issue #560
This function was badly copied and pasted from the f4 library, where there are
two functions, rcc_set_main_pll_hsi and rcc_set_main_pll_hse which combine
source, multipliers, dividers and other pll factors.
On F3, (not all of them, but the ones we support now), the function as
implemented has nothing to do with hsi / hse, and instead is simply selecting
the PLL multiplier.
Copypasta from f4 rcc code was only modified to shift the result, but not clear
the existing settings properly. Add mask/shift definitions and use them
properly.
The filename has always been wrong, "6" is a temperature grade, but f405 and
f407 are in the same datasheet, and all have the 64k CCM. Add it to the linker
script.
TSC_IOGxCR is actually a 32 bit register, of which 13 bits are used
(rest are reserved).
Also, added x-1 since G0 is not a valid group, TSC_IOGCSR_GxE(1) is supposed
to be at 0x34, not 0x38.
Was only in the (obviously out of date) documented example and as a
declaration. No implementations. Dropping immediately, but documentation
still needs further work.
Most changes are noise from doxygen.
Readme udpated to explain newer FP_FLAGS for m7
stm32f7 library is skipped if the toolchain doesn't support it yet.
GUSBCFG TRDT fields have very particular meanings, and the field should be set
depending on your bus speed. There's no 8/16bit meaning in any current
reference manual for this field.
Fixes github issue #530
All the macro arguments that are user supplied, or potentially, wrap properly
in () as good practice.
Probably missed one or two, and a lot of them are possibly unnecessary, but
it's straightforward to just do it always.
Fixes github issue #321
Renamed every instance of variable CFLAGS in target specific Makefiles
to TGT_CFLAGS to free up CFLAGS for user defined compiler flags.
Added information in README.md about existence and usage of CFLAGS
environment variable in build process.
Control transfers can transfer less than was requested by the host in the
wLength field. if this short transfer is a multiple of the endpoint's packet
size, a zero length packet must be sent.
Adds tests for a range of control transfer IN requests, and properly supports
this in the core. Based heavily on work by Kuldeep Dhaka.
See https://github.com/libopencm3/libopencm3/pull/505
and https://github.com/libopencm3/libopencm3/pull/194 for original discussion.
Tested with stm32f4, stm32f103 and stm32l053.
