* altos: Get stm32l pwm driver workingKeith Packard2015-12-25
| | | | | | | | | | | | | Fix the CCMR1_OC1PE and CCMR2_OC3PE values. Disable clock when no PWM outputs are running. Fix the apb1enr value for the timer. Set ARR value to PWM_MAX - 1 -- ARR is off by one. Sets the GPIO pins to 40MHz bandwidth for sharper edges. Tested on EasyMega, but that code is not included as it breaks the companion protocol.

* altos: Replace ao_alarm/ao_clear_alarm with ao_sleep_forKeith Packard2015-02-13
| | | | | | | | | | | | | | | | Having arbitrary alarms firing in the middle of complicated device logic makes no sense at all. Therefore only correct use of ao_alarm and ao_clear_alarm was around a specific ao_sleep call, with correct recovery in case the alarm fires. This patch replaces all uses of ao_alarm/ao_sleep/ao_clear_alarm with ao_sleep_for, a new function which takes the alarm timeout directly. A few cases which weren't simply calling ao_sleep have been reworked to pass the timeout value down to the place where sleep *is* being called, and having that code deal with the return correctly.

* altos/stm: Add ability to delay STDIO usage for serial portsKeith Packard2015-02-01
| | | | | | | | Bluetooth needs to delay adding the serial port to stdio until the link is up and running. The cc1111 serial driver had DELAY_SERIAL_*_STDIN bits which have been added to the STM serial driver. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos/stm: Fix typo in stm32l.hKeith Packard2015-01-26
| | | | | | This crept in while working on the stmf0 bits. oops. Signed-off-by: Keith Packard <keithp@keithp.com>
* ao-tools: Add --wait option to ao-usbloadKeith Packard2015-01-25
| | | | | | | This waits forever for USB writes to complete, instead of timing out after five seconds. Useful when debugging the device. Signed-off-by: Keith Packard <keithp@keithp.com>

* altos: Mark STM ao_spi_send as taking const pointerKeith Packard2014-10-24
| | | | | | We don't write to this, so let it be const for type checking Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Rework packet receive for cc1120Keith Packard2014-07-05
| | | | | | | | | | Instead of blocking on PQT, just set up the receiver to start going and when the first bit interrupt comes in, grab the SPI bus if possible and configure it for reception. This improves sensitivity in the radio by a significant amount while making the code conceptually a bit nicer. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Fake flight code changes in kernel and stmKeith Packard2014-05-27
| | | | | | | Redirects data input from local sensors to USB sourced data, leaving USB enabled when the computer goes into pad mode. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: stm and lpc ao_boot.h were identical. move to kernel.Keith Packard2014-05-15
| | | | | | | These two files were absolutely identical, so share them by moving under kernel instead.x Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Use explicit boot loader signal in ao_boot_rebootKeith Packard2014-05-15
| | | | | | | | Instead of just "knowing" that ao_boot_loader will be passed zero when the application wants to get back to the boot loader, explicitly define the values so that both sides always agree. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos/stm: Use #define'd constants for GPIO register addressesKeith Packard2014-05-12
| | | | | | | This lets the compiler short-circuit the tests in ao_enable_gpio and ao_disable_gpio to save a bit of code space and time. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos/stm: Figure out available flash space based on chip id registersKeith Packard2014-05-12

* altos/stm: Use flash address of boot loader instead of 0x0Keith Packard2014-05-12
| | | | | | | Flash is at 0x08000000, but when the chip boots, it can be at 0x0 as well. Use the 0x08000000 address when rebooting to flash Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Simplify quadrature trackingKeith Packard2014-05-09
| | | | | | | | | | | | Set the timer to 200Hz for a 5ms debounce interval. Then, simply look for transitions ending in both bits in the encoder being off, which indicates the the encoder is resting in a detent. If bit '2' is turning off, the encoder was rotated clockwise, otherwise the encoder was rotated counter clockwise. This is a lot more reliable, although still not perfect.

* altos: Rename 'core' to 'kernel'Keith Packard2014-04-05

* altos/stm: Semantic error in STM usb disable caused it to not workKeith Packard2013-12-18
| | | | | | | The USB enable register wasn't actually getting rewritten with the enable bit turned off, so the USB device was still powered on in flight. Signed-off-by: Keith Packard <keithp@keithp.com>

* altos: Use all 16 bits of setup packet len when limiting reply lenKeith Packard2013-12-17
| | | | | | | | | We were only using the low 8 bits of the setup packet reply max len, which meant that if the other side sent a weird max len (as Windows 7 does), then we'd truncate our setup reply to whatever was in the low 8 bits of that value. Signed-off-by: Keith Packard <keithp@keithp.com>

* altos: Allow use of internal EEPROM for config storageKeith Packard2013-11-12
| | | | | | | | | | | This stops exposing eeprom as 'storage' and instead exposes it with a separate eeprom API so that it can be used for config storage without also using it for flight log storage. The config code has been changed to allow it to either use storage for configuration data or eeprom. Signed-off-by: Keith Packard <keithp@keithp.com>
