4f1d891067 arch/: Within the OS, nxisg_usleep() should be used instead of usleep(). usleep() is a cancellation point and sets the errno value. Neither of which should be done inside the OS. 2019-11-29 17:54:43 -06:00

a6b31e3f03 arch/arm/src/lpc17xx_40xx/lpc17_40_ethernet.c: Use usleep() instead of up_delay() for large wait times. 2019-10-04 13:01:47 -06:00

08b596d26d rch/arm/src/lpc17xx_40xx/lpc17_40_i2c.c: Respect the I2C_M_NOSTART flag. Sending a restart condition when not requested will break other drivers that depend on this behavior. 2019-09-17 16:14:58 -06:00

366053e464 Fix typos, 1 in a #define, others in comments. This changes one definition: _MQ_TIMEDRECIEVE is changed to _MQ_TIMEDRECEIVE. It appears this symbol is not used anywhere. 2019-09-11 08:56:56 -06:00

68bbc8438c drivers/timers/pwm.c: Move the pwm/pwm.c driver to timers/pwm.c, The drivers/pwm contained only one .c file (pwm.c), so to avoid the proliferation of sub-directories inside drivers/ is better to move the pwm.c driver to drivers/timers. The pwm.h header was moved to include/nuttx/timers to keep consistency, so all files referencing it need to be updated. 2019-09-02 07:57:10 -06:00

913de5e216 arch/arm/src/lpc17xx_40xx/lpc17_40_can.c: f BOARD_CCLKSEL_DIVIDER is not equal to 1 on LPC178x or LPC40xx then base clock rate is calculated incorrectly because CCLK frequency does not correspond to PLL0 clock which is used for PCLK. This is partially workaround solution. It would be probably better to define BOARD_PCLK_FREQUENCY even for LPC176x targets and use that to replace divisor by base_clock in up_dev_s. 2019-08-13 16:16:49 -06:00

a1f1adb878 arch/arm/src/lpc17xx_40xx/lpc17_40_ethernet.c: Fix the initialization for DP83848x PHYs. The DP83848x requires the RMII mode to be manually enabled through the MII_DP83848C_RBR register. Before querying the speed and mode it should wait for the link to be established. 2019-08-07 09:22:50 -06:00

41d3ef5f1b arch/arm/src/lpc17xx_40xx/lpc17_40_ethernet.c: Follow the procedure listed in the LPC176x/5x User Manual when reading from and writing to the PHY's registers (section 10.11.14). I couldn't see any behavioral change after this commit, but nonetheless is a good practice to follow the manufacturer's recommended procedure. 2019-08-07 09:01:10 -06:00

17518b4a7d arch/arm/src/lpc17xx_40xx/Kconfig: Add missing LPC17_40_PHY_CEMENT_DISABLE config to the lpc17xx Kconfig file. For some reason this config wasn't referenced anywhere else except in arch/arm/src/lpc17xx_40xx/lpc17_40_ethernet.c. 2019-08-07 08:59:38 -06:00

f0b74380a5 arch/arm/src/lpc17xx_40xx/lpc17_40_i2c.c: Calculate the appropriate timeout for I2C transfers. Depending on the bus frequency and transfer size, I2C transactions can take quite a bit, so a fixed timeout is not a good solution. Calculating the timeout at run time poses some overhead but still better than aborting long transactions. 2019-07-25 13:07:28 -06:00

38b9862902 arch/arm/src/lpc17xx_40xx/lpc17_40_i2c.c: Abort I2C transfers if a timeout has occurred. If a timeout has occurred in the middle of a I2C transfer, the next I2C interrupt should abort any transfers and send a stop condition to the corresponding I2C bus. Failed to do so will result in memory corruption / undefined behavior as priv->msgs points to a region of memory it doesn't owns anymore after lpc17_40_i2c_start returns. 2019-07-25 08:33:31 -06:00

e5dfd805e6 Merged in jjlange/nuttx/lpc40xx (pull request #946) 
Add support for LPC40xx family chips

* Corrected a few peripheral definitions and pin functions for the LPC17xx family.
    Added configuration options, chip definitions, and additional pin functions for the LPC40xx family.
    Added board configurations for Embedded Artists LPC4088 Quickstart board and LPC4088 Developer's kit.  These configurations are still something of a work in progress.  In particular, the LCD functionality is untested.

* First pass rename in *.c and *.h files.

* Renamed LPC17XX to LPC17XX_40XX in config files

* Rplaced LPC17xx with LPC17xx/LPC40xx in .c files

* Replaced LPC17xx with LPC17xx/LPC40xx in .h files

* Updated some documentation

* Working on moving directories

* moved arch/arm/src/lpc17xx and arch/arm/include/lpc17xx to lpc17xx_40xx

* Renamed LPC17_* constants / configuration options to LPC17_40_*

* Updated chip family name defines

* Renamed some chip-specific files

* Updated references to renamed files

* Updated references to lpc17_ to lpc17_40_

* Renamed source files from lpc17_* to lpc17_40_*

* Clean up white space
