Roger Clark 7dcbbc85b0 Fix bug USB divider for 48Mhz operation. Also added support for 48Mhz to Maple mini and Generic F103C (Note. There is a bug in tone() at 48Mhz) 2017-01-09 20:27:07 +11:00
stevstrong 073aa23ed2 Merge remote-tracking branch 'refs/remotes/rogerclarkmelbourne/master' 2016-10-16 23:02:16 +02:00
Bubulindo 5c13d8b0d4 Addition of a better way to deal with the Onboard ADC. 
This modification adds support for a STM32ADC library. There are a
couple of examples on how to use it. The library allows usage of the
ADC with DMA in circular mode or scan mode, it allows the ADC to be
used in scan mode. And also to use the EOC interrupt.
More functionality needs to be added and will be in time.

Eventually the util files will be moved into the adc files in the core.

Roger Clark 88d2457f30 STM32F1 core: Implemented changes already made to the GD32F1 core to use F_CPU instead of hard coded values for 72000000 and (F_CPU -1) instead of 71999999 and to replace other hard coded values related to the clock freqency. Also updated the code so that the USB clock was disabled in setup_clock_prescalers to allow it to be changed in that function during initialisation, in case altermative prescaler values for USB are required, e.g. for operation at 48Mhz 2015-09-06 07:51:40 +10:00
Roger Clark bb535029cb updated setup_nvic for maple mini, which seems to have been missed when I made the changed to do with removing VECT_TAB_FLASH 2015-05-06 03:09:15 +10:00
rogerclarkmelbourne fddefc13a9 Separated USB Serial functionality definitions from the BOOTLOADER_maple definition, so that generic boards can use USB serial without needing to have the bootloader and the disconnect hardware. NOTE. I have only tested the SERIAL_USB on the F103ZE board, it may not work on other generic boards 2015-04-25 15:28:45 +10:00
Roger Clark 5f83c13285 renamed top level folder STM32F1XX to STM32F1 to correspond to other top level folder names e.g. STM32F3 and STM32F4 2015-02-24 20:13:04 +11:00
