* altos/lisp: Take advantage of implicit progns in hanoi demoKeith Packard2016-11-17
| | | | | | | Remove extra progn wrappers now that cond, lambda and while all support implicit ones. Signed-off-by: Keith Packard <keithp@keithp.com>

* altos/lisp: Eliminate compiler warning about array bounds at -O3Keith Packard2016-11-17
| | | | | | | | | Using ao_lisp_pool - 4 caused the compiler to whinge about computing an address outside the bounds of the array. Sigh. Restructure the code to do the adjustment-by-4 in the integer computations instead of the pointer ones. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos/test: Disable position independent executablesKeith Packard2016-11-17
| | | | This makes debugging programs so much harder
* altos/lisp: Optimize chunk searching in collectKeith Packard2016-11-17
| | | | | | | Note range of existing chunks to exclude objects outside. Only look at chunks which have been set to reduce loop cost. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos/lisp: Add incremental collectionKeith Packard2016-11-17
| | | | | | | | | | | | Realizing that long-lived objects will eventually float to the bottom of the heap, I added a simple hack to the collector that 'remembers' the top of the heap the last time a full collect was run and then runs incremental collects looking to shift only objects above that boundary. That doesn't perfectly capture the bounds of transient objects, but does manage to reduce the amount of time spent not moving persistent objects each time through the collector.

* altos/lisp: Make hanoi example output a bit prettierKeith Packard2016-11-17
| | | | | | Make the towers symmetrical instead of lopsided. Much nicer looking. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos/lisp: remove nth from hanoi.lispKeith Packard2016-11-17
| | | | | | It's now in ROM. Signed-off-by: Keith Packard <keithp@keithp.com>

* altos/lisp: Improve hanoi demoKeith Packard2016-11-17
| | | | | | | Repaint in place, without first clearing. This makes the updates a lot clealyer looking. Signed-off-by: Keith Packard <keithp@keithp.com>

| | | | | | This helps tune the allocator Signed-off-by: Keith Packard <keithp@keithp.com>
* altos/lisp: Append a CRC to the saved image to validate on restoreKeith Packard2016-11-17
| | | | | | | The CRC is actually of the ROM bits, so we can tell if the restored image relates to the currently running code. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos/lisp: Add save/restore to ao_lisp_testKeith Packard2016-11-17
| | | | | | Allow testing of the save/restore code under Linux. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos/lisp: Share mark function for mark and moveKeith Packard2016-11-17
| | | | | | | These two operations both wanted to walk the referenced objects; sharing is caring. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos/lisp: add length, pack, unpack and flushKeith Packard2016-11-17
| | | | | | lots more builtins Signed-off-by: Keith Packard <keithp@keithp.com>

* altos/lisp: Clean up OS integration bits, add defunKeith Packard2016-11-17
| | | | | | | Provide an abstraction for the OS interface so that it can build more cleanly on Linux and AltOS. Add defun macro. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos/lisp: working on lexical scopingKeith Packard2016-11-17
| | | | | | Not working yet Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Add lambda support to lispKeith Packard2016-11-17
| | | | Signed-off-by: Keith Packard <keithp@keithp.com>
* altos/lisp: Separate out values from atomsKeith Packard2016-11-17
| | | | | | | | | | | This enables changing values of atoms declared as constants, should enable lets, and with some work, even lexical scoping. this required changing the constant computation to run ao_lisp_collect() before dumping the block of constant data, and that uncovered some minor memory manager bugs. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos/lisp: Change lisp objects to use ao_poly everywhere. Add constKeith Packard2016-11-17
| | | | | | | | | | | This makes all lisp objects use 16-bit ints for references so we can hold more stuff in small amounts of memory. Also adds a separate constant pool of lisp objects for builtins, initial atoms and constant lisp code. Now builds (and runs!) on the nucleo-32 boards. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Add lisp readerKeith Packard2016-11-17

* altos/test: Fix testsKeith Packard2016-10-30
| | | | | | | A couple of fixups for ao_flight_test to dump pyro info only when running in debug mode, and to change the aprs testing Signed-off-by: Keith Packard <keithp@keithp.com>
* Switch from GPLv2 to GPLv2+Keith Packard2016-07-12

* altos/test: Support old telemega eeprom file formats in ao_flight_testKeith Packard2015-03-10
| | | | | | | | The old eeprom format used different stoarge for the accel calibration data, which doesn't matter to this code, but the change in the format value does. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Sort out ao_gps_print altitude fetchingKeith Packard2014-10-25
| | | | | | | | | | ao_gps_print is used by both teledongle/telebt and the host-based GPS test code. The first instance uses the old internal GPS structure, containing just a 16-bit altitude while the second uses an ao_telemetry structure, which contains 32 bits split into two members. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Handle antenna down in ao_flight_testKeith Packard2014-09-29
| | | | | | | Parse the Pad orientation config value and flip the accelerometer value back around in antenna down configuration. Signed-off-by: Keith Packard <keithp@keithp.com>

* altos/test: Build TeleMetrumV2 flight test variantKeith Packard2014-07-13

* altos: Use 32-bits for flight state data (alt/speed/accel)Keith Packard2014-07-10
| | | | | | | Stores 32-bits for all of the flight parameters. Uses 64-bit intermediates for kalman computation. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Extend GPS altitudes to at least 24 bits everywhereKeith Packard2014-07-10
| | | | | | | | Telemetry gets a special 'mode' flag indicating that 24-bit data is present; log files get new data and log readers are expected to detect that via the firmware version number. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos/ao_flight_test: Get the Tmega version compiling againKeith Packard2014-06-24
| | | | | | A few changes broke this recently. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos/aprs: Encode last serial number in SSID. Transmit serial in commentKeith Packard2014-06-20
| | | | | | | | This makes it a lot easier to tell which device is sending information, and to receive data from multiple devices on the same receiver. Signed-off-by: Keith Packard <keithp@keithp.com>

| | | | | | Verify fixed point version against naïve implementation Signed-off-by: Keith Packard <keithp@keithp.com>
* altos/test: Fix ADC structure for mega, use ao_config.hKeith Packard2014-05-25
| | | | | | | | This switches from hand-coding the ao_config structure to using ao_config.h and also updates the ADC structure for ao_flight_test_mega to using the same one as telemega does natively Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Make MS5607 PROM a public variableKeith Packard2014-05-25
| | | | | | | This will let the fake flight code update it as necessary, without creating a new interface in ao_ms5607.c Signed-off-by: Keith Packard <keithp@keithp.com>
* altos/test: Parse mega ground data. Fix pyro parsingKeith Packard2014-05-21
| | | | | | This gets ao_flight_test_mega working with eeprom files Signed-off-by: Keith Packard <keithp@keithp.com>
* altos/test: Get APRS generation test working againKeith Packard2014-05-21
| | | | | | | APRS now includes sat info, so we have to fake that up to generate an APRS test file Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Rename 'core' to 'kernel'Keith Packard2014-04-05
| | | | | | | core remains a bad name to use -- dirvish skips files (and directories, it seems) with that name. Signed-off-by: Keith Packard <keithp@keithp.com>
