altos: Restructure altos build to prepare for multi-arch support

2011-08-26T03:49:11+00:00

Split out sources into separate directories: core: architecture and product independent bits cc1111: cc1111-specific code drivers: architecture independent drivers product: product-specific sources and Makefile fragments util: scripts for building stuff This should have no effect on the built products, but testing is encouraged Signed-off-by: Keith Packard

altos: Switch ao_stdio.c data to pdata

altos: Solidify BT connections

2011-04-19T20:20:19+00:00

Use delays while sending commands to BT module. Don't use BT for stdio until the module is initialized. Add \r to name setting command Don't require 'connected' signal for command input. Signed-off-by: Keith Packard

altos: Make cmd echo per-connection instead of global

2011-04-02T00:25:07+00:00

Allow different connections to use different echo values, permitting the packet link to turn off echo while the USB link still has it on. Signed-off-by: Keith Packard

altos: expose set of available stdio values

2011-04-01T21:04:58+00:00

This lets external code manipulate which connection to communicate over. Signed-off-by: Keith Packard

altos: Add initial TeleBT code

2011-04-01T03:59:07+00:00

Prototyping with a TeleMetrum v0.1 board and a serial link to a bluetooth module. Signed-off-by: Keith Packard

altos: Split up flight code into separate flight/sample/kalman bits

2011-03-29T00:54:44+00:00

The flight code mashed together data processing, filtering and actual flight managament into one giant pile. Split things up so that we have: ao_sample.c: Sensor data processing. Reads the ring, handles calibration ao_kalman.c: Filter the data to track the accel/speed/height values ao_flight.c: Flight state management, specific to rocketry. The plan is to re-use ao_sample.c and ao_kalman.c for hardware not specifically designed for rocketry, like TeleNano. Signed-off-by: Keith Packard

Fix all stdio reading functions to be __critical

2010-05-05T08:33:25+00:00

Oh, right SDCC has '__critical' to mark sections of code that need to run with interrupts disabled; no need to use EA = 0 and EA = 1. Signed-off-by: Keith Packard

Disable interrupts while reading from stdin

2010-05-05T07:44:42+00:00

With multiple input source support, there is a lag between asking a device if it has data and then waiting for more data to appear. If an interrupt signalling additional input arrives in this interval, we'll go to sleep with input available. This patch uses a big hammer by just disabling interrupts for the whole process.

Change altos build process to support per-product compile-time changes

2010-02-21T04:30:27+00:00

This creates per-product subdirectories and recompiles everything for each product, allowing per-product compile-time changes for things like peripheral pin assignments and attached serial devices. Signed-off-by: Keith Packard
