| * altoslib: Keep old GPS values when updating dataKeith Packard2017-12-11
| | | | | | | | | | | | | | This way, updating satellite information doesn't drop all of the regular GPS data on the floor. Signed-off-by: Keith Packard <keithp@keithp.com>
| * altos: Actually store current MPU9250 data in data ringKeith Packard2017-12-11
| | | | | | | | | | | | | | The ring is updated when the ADC finishes; all of the other sensor data needs to be copied in at that point. Signed-off-by: Keith Packard <keithp@keithp.com>

| * altos/drivers: Hook up mag sensor for MPU9250Keith Packard2017-12-11
| | | | | | | | | | | | | | Set mag sensor to provide data at 100Hz. Set i2c master to pull mag data at sample rate (200Hz). Signed-off-by: Keith Packard <keithp@keithp.com>
| * altos/scheme: Allow ao_scheme_read_eval_print to be restartedKeith Packard2017-12-11
| | | | | | | | | | | | Reset exceptions at the top so that we can call it more than once. Signed-off-by: Keith Packard <keithp@keithp.com>
| * altos: Allow building with newlib + avr stdio on ARMKeith Packard2017-12-11
| | | | | | | | | | | | | | Redefines some stdio bits so that we can build with either pdclib or newlib + avr stdio. Signed-off-by: Keith Packard <keithp@keithp.com>

| | | | | | | | Signed-off-by: Keith Packard <keithp@keithp.com>
| * altos/lambdakey-v1.0: Switch to newlib, get things compiling againKeith Packard2017-12-11
| | | | | | | | | | | | | | scheme is now way too large to fit on this device; some subsetting is clearly indicated. Signed-off-by: Keith Packard <keithp@keithp.com>
| * altos/scheme: Add Makefile for scheme test appKeith Packard2017-12-11
| | | | | | | | Signed-off-by: Keith Packard <keithp@keithp.com>
| * altos/scheme: Make test scheme app heap maximum sizeKeith Packard2017-12-11
| | | | | | | | | | | | It's only 32kB. Signed-off-by: Keith Packard <keithp@keithp.com>
| * altos/scheme: Make eqv? work for numbers and stringsKeith Packard2017-12-11
| | | | | | | | | | | | | | Large numbers, floats and strings need a value check, not just a comparison between ao_polys Signed-off-by: Keith Packard <keithp@keithp.com>
| * altos/scheme: Stash cons across value allocation in compareKeith Packard2017-12-11
| | | | | | | | | | | | | | Large ints, strings and floats can cause allocation, requiring that the 'cons' pointer be stashed and retrieved in case it moved. Signed-off-by: Keith Packard <keithp@keithp.com>
| * altos/scheme: add list-copyKeith Packard2017-12-11
| | | | | | | | | | | | A lot easier as a built-in; the obvious scheme version is recursive. Signed-off-by: Keith Packard <keithp@keithp.com>
| * altos/scheme: Use 64-bit ints to track memory allocation statsKeith Packard2017-12-11
| | | | | | | | | | | | | | These are only collected for debug purposes, but can get quite large if the interpreter runs for a while. Signed-off-by: Keith Packard <keithp@keithp.com>
| * altos/scheme: Add a bunch of string and vector builtinsKeith Packard2017-12-11
| | | | | | | | | | | | Just make the language closer to r7rs Signed-off-by: Keith Packard <keithp@keithp.com>

| | * altos/scheme: Avoid crashing with non-list in lengthKeith Packard2017-12-10
| | | | | | | | | | | | | | | | | | | | | Use ao_scheme_cons_cdr to fetch the next list element as that returns NULL for non-cons elements. Signed-off-by: Keith Packard <keithp@keithp.com>
| | * altos/scheme: Add vectorsKeith Packard2017-12-10
| | | | | | | | | | | | | | | | | | Constant time and smaller can be a feature. Signed-off-by: Keith Packard <keithp@keithp.com>

| | * altoslib: Fix 8 to 12 bit conversion for Mega pyro voltage dataKeith Packard2017-12-09
| | | | | | | | | | | | | | | | | | | | | The conversion was losing the replicated top four bits by shifting by the wrong amount. Signed-off-by: Keith Packard <keithp@keithp.com>
| | * altos/scheme: Let readline know if there's a list in progressKeith Packard2017-12-09

| | | | | | | | | | | | | | | | | | | | | | | | | | | ao_scheme_make_const This ensures that a parallel build will wait for ao_scheme_builtin.h to be complete before attempting to compile ao_scheme_make_const Signed-off-by: Keith Packard <keithp@keithp.com>
| | * altos/scheme: Move scheme test program to scheme sub-directoryKeith Packard2017-12-05
| | | | | | | | | | | | | | | | | | Keeps it away from the usual test setup Signed-off-by: Keith Packard <keithp@keithp.com>
| | * altos/scheme: Rename to 'scheme', clean up buildKeith Packard2017-12-05
| | | | | | | | | | | | | | | | | | | | | | | | | | | Constant block is now built in a subdir to avoid messing up source directory. Renamed to ao_scheme to reflect language target. Signed-off-by: Keith Packard <keithp@keithp.com>
| | * altos/lisp: Switch to scheme formal syntax for varargsKeith Packard2017-12-03
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Scheme uses bare symbols to indicate a varargs parameter; any bare (i.e., not wrapped in a cons cell) parameter will get the 'rest' of the parameter list. This works for lambdas, nlambdas and macros. As a result, the 'lexpr' form has been removed as it is equivalent to a lambda with a varargs formal. Signed-off-by: Keith Packard <keithp@keithp.com>
| | * altos/lisp: Fix stash usage across frame allocationKeith Packard2017-12-03
| | | | | | | | | | | | | | | | | | | | | Must un-stash before allocation failure check. Use frame_stash instead of poly_stash for frames. Signed-off-by: Keith Packard <keithp@keithp.com>
| | * altos/lisp: Check only cdr base type when moving cons cellsKeith Packard2017-12-03
| | | | | | | | | | | | | | | | | | | | | | | | The cdr may have moved, so we can't look at the target object type. Fortunately, the base type encoded in the reference itself is sufficient to check for a non-cons cdr. Signed-off-by: Keith Packard <keithp@keithp.com>
| | * altos/lisp: Split out read debug, add memory validationKeith Packard2017-12-03
| | | | | | | | | | | | | | | | | | | | | | | | Split read debug into a separate #define to reduce debug noise Add some memory validation -- validate stash API, and validate cons_free calls. Signed-off-by: Keith Packard <keithp@keithp.com>
| | * altos/lisp: use strtof instead of atofKeith Packard2017-12-02
| | | | | | | | | | | | | | | | | | atof returns double, strtof returns float. Signed-off-by: Keith Packard <keithp@keithp.com>
| | * altos/lisp: Convert more builtin lisp code to scheme formatKeith Packard2017-12-02
| | | | | | | | | | | | | | | | | | Use defines where possible, use (define (name args ...)) form for lambdas Signed-off-by: Keith Packard <keithp@keithp.com>
| | * altos/lisp: Overflow int computations to floatKeith Packard2017-12-02
| | | | | | | | | | | | | | | | | | When an int computation overflows, switch to float. Signed-off-by: Keith Packard <keithp@keithp.com>

| * altoslib: Add support for TeleMega v3.0 log filesKeith Packard2017-12-02
| | | | | | | | | | | | | | | | | | These look much like TeleMega v2.0 log files, except that the mag sensor data now comes from the mpu9250 instead of an external hmc5883. The gyro and 3-axis accel data from the mpu9250 are the same as the mpu6000. Signed-off-by: Keith Packard <keithp@keithp.com>

| | | | | | | | | | | | | | Use MPU9250 for accel, gyro and mag data in logging, telemetry and flight status computations. Signed-off-by: Keith Packard <keithp@keithp.com>
| * altos/lisp: split set/def. Add def support to lambdasKeith Packard2017-12-01
| | | | | | | | | | | | | | | | In scheme, set can only re-define existing variables while def cannot redefine existing variables in lambda context. Def within lambda creates a new variable at the nearest enclosing scope. Signed-off-by: Keith Packard <keithp@keithp.com>
| * altos/lisp: Split out frame vals from frame structKeith Packard2017-12-01
| | | | | | | | | | | | | | This lets the frame be resized without moving the base structure. The plan is to allow all frames to be resized, not just the global frame. Signed-off-by: Keith Packard <keithp@keithp.com>
