ef059f78ac STM32 PWR: Adds stm32_pwr_getsbf and stm32_pwr_getwuf functions that return the standby flag and the wakeup flag PWR power control/status register. 2017-09-28 07:50:21 -06:00

3ca3674cca Update/fix last commit: On some STM32's, the CSR regiser is 18 vs. 16 bits wide. Need to use 32-bit register accesses. 2017-09-08 14:21:24 -06:00

47be509d79 Rename CONFIG_STM32_STM32F40XX to CONFIG_STM32_STM32FXXXX since it is used by F4 parts other than F40x 2017-07-06 10:20:14 -06:00

0bf4893b2c STM32: Allow clock frequencies > 168 Mhz on stm32f427/429. We need to enable the power overdrive for this case. This patch allows the required bits to be set in proper sequence. It also modifies the local register access operations to allow more than 16-bit registers. 2017-06-20 11:56:54 -06:00

483f012600 Initial implemention of the STM32 F37xx SDADC module. There are also changes to ADC, DAC modules. SDADC has only been tested in DMA mode and does not support external TIMER triggers. This is a work in progress. 2016-10-25 14:14:10 -06:00

8b5833f7fe A consequence of Max's change to the logic to enable access to the backup domain is that every call to enabledbkp(true) must be followed by a matching call to enablebkp(false). There was one cse in both RTCC drivers where that may not always be true. 2016-08-09 11:33:47 -06:00

d3ef23e05a STM32 PVD: Adds support for STM32's Programmable Voltage Detector feature. I put register access behind CONFIG_STM32_ENERGYLITE as have not checked F1/F2/F4 etc. manuals. Tested on STM32L1. PVD interrupt looks generic, at least #defines it needs are in headers for every chip variant. By Dmitry Nikolaev, submitted by Juha Niskanen. 2015-04-28 06:37:59 -06:00

4c0b8fba52 Fix an error introduced into stm32_pwr_enablebkp(). That function must preserve the previous state of backup domain access on return. 2015-04-18 07:31:20 -06:00

0dc70108b8 STM32: Fix for compilation introduced by last backup RAM change. Not sure it it is correct, be now things do compile 2015-02-21 17:51:03 -06:00

7d43cf2087 Changes to support fully write protecting the backup domain. N.B. stm32_pwr_enablebkp did not account for the delay from enable to the domain being writable. The KISS solution is a up_udelay. A more complex solution would be a negated write test with restore. From David Sidrane. 2015-02-21 14:53:33 -06:00
