Damien George	89ebb3325b	stm32/boards/pllvalues.py: Support HSx_VALUE defined without uint32_t.	2019-06-25 14:18:24 +10:00
Damien George	34cae24e30	stm32/boards/pllvalues.py: Search nested headers for HSx_VALUE defines.	2019-05-31 21:44:53 +10:00
Damien George	3fbf32b947	stm32/powerctrl: Support changing frequency when HSI is clock source. This patch makes pllvalues.py generate two tables: one for when HSI is used and one for when HSE is used. The correct table is then selected at compile time via the existing MICROPY_HW_CLK_USE_HSI.	2019-05-02 13:00:00 +10:00
Damien George	47550ef2cd	stm32: For MCUs that have PLLSAI allow to set SYSCLK at 2MHz increments. MCUs that have a PLLSAI can use it to generate a 48MHz clock for USB, SDIO and RNG peripherals. In such cases the SYSCLK is not restricted to values that allow the system PLL to generate 48MHz, but can be any frequency. This patch allows such configurability for F7 MCUs, allowing the SYSCLK to be set in 2MHz increments via machine.freq(). PLLSAI will only be enabled if needed, and consumes about 1mA extra. This fine grained control of frequency is useful to get accurate SPI baudrates, for example.	2018-09-11 16:42:57 +10:00
Damien George	01dd7804b8	ports: Make new ports/ sub-directory and move all ports there. This is to keep the top-level directory clean, to make it clear what is core and what is a port, and to allow the repository to grow with new ports in a sustainable way.	2017-09-06 13:40:51 +10:00
