* altos: Add missing build files for avr/attiny devicesKeith Packard2019-09-18
| | | | | | These were sitting in my src directory but not in git Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Move common build definitions to src/Makefile.defsKeith Packard2019-02-18
| | | | | | | | This cleans up the build process for all architectures, providing a common place to specify vpath, cflags and build rules for various common files. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Declare task stack as union of uint8_t and uint32_tKeith Packard2019-02-18
| | | | | | | Support -Wcast-align and -Wpointer-arith while still allowing architectures to pick whether they want an 8-bit or 32-bit stack. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Clean up AO_ROMCONFIG bitsKeith Packard2018-10-13
| | | | | | | Remove address parameter (doesn't work with gcc), create shared ao_romconfig in kernel. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Add generic LED driver.Keith Packard2018-10-13
| | | | | | | | | | | This driver uses the generic GPIO functions and allows per-LED port and pin configuration. It supports up to 32 LEDs. Rename SoC-specific LED drivers. Remove enabled parameter to ao_led_init Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Eliminate 'pin' field from GPIO functionsKeith Packard2018-10-13
| | | | | | | This was used with the 8051 bit-addressing mode to provide single-instruction access to GPIO pins. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Remove 8051 address space specifiersKeith Packard2018-10-13
| | | | Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Make CDC ACM 'line coding' publicKeith Packard2017-05-04
| | | | | | This allows other systems to see what baud rate the host has requested. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos/avr: Avoid warning about unused args in stdio_put and stdio_getKeith Packard2017-02-20
| | | | Signed-off-by: Keith Packard <keithp@keithp.com>
* Switch from GPLv2 to GPLv2+Keith Packard2016-07-12
| | | | Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Declare port register type only in arch headerKeith Packard2014-11-06
| | | | | | | Instead of defaulting to 8 bits, explicitly require declaration of the type of the port register for each architecture. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Expose ao_usb_running globallyKeith Packard2014-02-18
| | | | | | This lets other bits of the code know when USB has been connected. Signed-off-by: Keith Packard <keithp@keithp.com>
* Add --with parameters to configure for compiler selectionnew-stateKeith Packard2013-10-08
| | | | | | | | This allows the user to specify which compiler to use for each target CPU. Also checks to make sure the arm compiler supports -m0 and -m3 cpu type flags. The build now actually uses the specified compilers too. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Eliminate stdio looping when system has a single stdio sourceKeith Packard2013-05-07
| | | | | | No need to loop if there's only one Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Do not release interrupts from any pollchar functionKeith Packard2013-03-31
| | | | | | | | | | | getchar relies on interrupts being blocked across the pollchar calls and into the sleep call or it may go to sleep with data pending. This prefixes all pollchar functions with _ to indicate that they are to be called with interrupts blocked and eliminates all interrupt manipulation calls from within the pollchar functions. Signed-off-by: Keith Packard <keithp@keithp.com>
* Update avr ao_spi_slave code to match API changesKeith Packard2013-01-13
| | | | | | Made the interface use void * for pointers and uint16_t for lengths Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Make stdio 8-bit clean by making pollchar return intKeith Packard2012-11-30
| | | | | | | | | | We were stealing one value (0xff) in the return value from pollchar to indicate 'not ready yet'. Instead of doing that, use the integer value -1 and have pollchar return an int instead of a char. That necessitated cleaning a few other bits to make sure that 0xff wouldn't get promoted to -1 on accident. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Leave interrupts disabled while checking for task to runKeith Packard2012-10-26
| | | | | | | Otherwise, we run the risk of an interrupt waking a task after we've decided to idle the CPU. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Add ao_arch_block/release_interrupts to avr and cc1111Keith Packard2012-10-25
| | | | | | Stop using cli/sei for AVR, add replacement to __critical for cc1111 Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Let AVR products override the stack size. Set telepyro to 104Keith Packard2012-10-22
| | | | | | Otherwise, telepyro doesn't have enough ram... Signed-off-by: Keith Packard <keithp@keithp.com>

* altos: Fix ao_delay function and move from per-chip code to ao_task.cKeith Packard2012-08-28
| | | | | | | ao_delay hasn't been chip-specific for a long time, and it had a bug in not calling ao_clear_alarm. Signed-off-by: Keith Packard <keithp@keithp.com>

* altos: Place STM config values at fixed addresses for re-useKeith Packard2012-07-17
| | | | | | | | Just like cc1111, stick the serial number and radio calibration values at known fixed addresses so that when re-flashing the board, we can go find the existing values. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Enable pyro channel control in telepyroKeith Packard2012-07-16
| | | | | | This should make the board actually work now. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Make ao_tick_count visibleKeith Packard2012-07-16
| | | | | | | Necessary to fetch it when interrupts are already disabled as we can't call ao_time then. Signed-off-by: Keith Packard <keithp@keithp.com>

| | | | Signed-off-by: Keith Packard <keithp@keithp.com>
* src: Add explicit 'pin' argument to ao_enable_outputKeith Packard2012-07-14
| | | | | | | This lets the cc1111 use the atomic bit operation instead of a mask, which is immune to interrupt issues as well as being a shorter code sequence. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: include targe SPI speed in get requestKeith Packard2012-06-27
| | | | | | | STM needs it to be provided when enabling the SPI device, so just fix AVR and cc1111 to do the same. Signed-off-by: Keith Packard <keithp@keithp.com>

* altos: Massive product config cleanupKeith Packard2012-04-14
| | | | | | | | Support multiple serial ports more cleanly Split out parts of ao.h into separate feature header files Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Add support for multiple SPI busses and sharing device driversKeith Packard2012-04-14
| | | | | | | | | | | | | | | | The STM32L151 has several SPI busses, and we want to use more than one, so add a 'bus' parameter to the SPI interfaces. To avoid wasting time on AVR and CC1111 processors which only use one SPI bus, elide those parameters from the actual functions by wrapping them with macros. Configuring chip select is now all macroized so that each chip can have its own version, allowing the STM to share the various SPI device drivers with the cc1111 and avr processors. Note that only the M25 driver has been ported; porting the others is 'trivial', but not necessary at this point. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Move SPI functions to architecture-specific locationKeith Packard2012-04-02
| | | | | | | | Some architecture specific stuff needs to use core altos code, so create new ao_arch_funcs.h files per architecture that get pulled in at the end of ao.h Signed-off-by: Keith Packard <keithp@keithp.com>
