altos: Declare port register type only in arch header

2014-11-06T23:58:42+00:00

Instead of defaulting to 8 bits, explicitly require declaration of the type of the port register for each architecture. Signed-off-by: Keith Packard

altos: Expose ao_usb_running globally

2014-02-18T17:44:52+00:00

This lets other bits of the code know when USB has been connected. Signed-off-by: Keith Packard

Add --with parameters to configure for compiler selection

2013-10-08T16:22:03+00:00

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

altos: Eliminate stdio looping when system has a single stdio source

2013-05-08T03:16:53+00:00

No need to loop if there's only one Signed-off-by: Keith Packard

altos: Do not release interrupts from any pollchar function

2013-03-31T19:24:24+00:00

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.

Update avr ao_spi_slave code to match API changes

2013-01-13T18:32:52+00:00

Made the interface use void * for pointers and uint16_t for lengths Signed-off-by: Keith Packard

altos: Make stdio 8-bit clean by making pollchar return int

2012-12-01T00:01:07+00:00

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

altos: Leave interrupts disabled while checking for task to run

2012-10-26T21:07:04+00:00

Otherwise, we run the risk of an interrupt waking a task after we've decided to idle the CPU. Signed-off-by: Keith Packard

altos: Add ao_arch_block/release_interrupts to avr and cc1111

2012-10-25T07:07:14+00:00

Stop using cli/sei for AVR, add replacement to __critical for cc1111 Signed-off-by: Keith Packard

altos: Let AVR products override the stack size. Set telepyro to 104

2012-10-23T04:37:25+00:00

Otherwise, telepyro doesn't have enough ram... Signed-off-by: Keith Packard
