* lcd_st7920: Add brief delay around gpio toggle calls on fast MCUsKevin O'Connor2019-08-101-0/+20
| | | | | | | | | On fast MCUs (like the SAMD51) it is possible for the gpio to toggle faster than the st7920 can accept. Add a small delay around the clock rise signal. Signed-off-by: Lars R. Hansen <popshansen@hotmail.com> Signed-off-by: Kevin O'Connor <kevin@koconnor.net>

* spicmds: Rework spi config commandsKevin O'Connor2019-08-067-81/+86
| | | | | | | | | | Rework the spi_config commands so that bus configuration and shutdown message configuration is done separately from the main "config_spi" command. This makes the spi configuration more flexible. It's now possible to use software spi without a CS pin. It's now possible to define multiple SPI messages to send on a shutdown event.

* stm32f1: Remove now unused src/stm32f1/ directoryKevin O'Connor2019-08-0511-1138/+0
| | | | | | | Now that the stm32f1 code has been merged into the stm32 code, there is no longer a need to keep the stm32f1/ directory. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
* stm32: Rename clock.c to stm32f4.cKevin O'Connor2019-08-052-1/+1
| | | | | | | Rename the clock.c file to stm32f4.c to make it more clear that the code is specific to the stm32f4 chips. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
* stm32: Rename stm32f4/ directory to stm32/Kevin O'Connor2019-08-0516-93/+90
| | | | | | | Now that the code in stm32f4/ can handle both stm32f1 and stm32f4 chips, rename the directory to just "stm32". Signed-off-by: Kevin O'Connor <kevin@koconnor.net>

* endstop: Rename mcu end_stop commands to endstopKevin O'Connor2019-07-121-35/+35
| | | | | | | | | Rename the commands. The main reason for this change is to force a micro-controller code updated (due to important bugfix in 7fefe52d). Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
* stepper: Don't update SF_LAST_DIR if SF_NEED_RESETKevin O'Connor2019-07-121-1/+3
| | | | | | | | If the move is not added to the move queue, then the SF_LAST_DIR setting must not be changed. Otherwise, it could result in an incorrect direction being set on the stepper after a homing operation. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
* lpc176x: Reset LPC_UART0->FDR when using serialKevin O'Connor2019-07-101-0/+1
| | | | | | | | | | The popular "LPC17xx-DFU-Bootloader" alters the LPC_UART0->FDR register, so be sure to reset it back to its default when using serial in Klipper. Reported by @b-vs. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>

| | | | | | | | Commit 1096075d changed CONFIG_CLOCK_FREQ to the actual cpu frequency, but that commit failed to update adc.c accordingly. That made the adc run 4 times slower. Make the corresponding change to adc.c. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>

| | | | | | | | Improve the precision of soft pwm pulses by allowing the host to directly specify the clock duration of the pulse. This improvement in precision may be noticeable when controller servos (and bltouch). Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
