altos: Provide ISR-based code paths for SPI

2012-05-19T03:19:18+00:00

This allows SPI to be entirely interrupt driven, with callbacks for completion. It's not tested yet... Signed-off-by: Keith Packard

altos: stm: pass DMA buffer index to DMA completion callback

2012-05-08T04:50:26+00:00

This lets the user know which DMA has finished. Signed-off-by: Keith Packard

altos: stm: delay during USB config with pull-up off

2012-05-08T04:49:24+00:00

This makes sure that a reboot will reliably cause the device to disconnect from the USB bus. Signed-off-by: Keith Packard

altos: stm: share i2c_stop code between send and recv

2012-05-08T04:47:17+00:00

This waits for the stop signal to appear on the bus, necessary before starting another transaction. Signed-off-by: Keith Packard

altos: stm i2c DMA for large recv appears to work

2012-05-07T06:54:13+00:00

Transaction appears to be clean on the i2c bus now; correct number of bytes received, and the nack and stop at the right time. This tests > 2 length reads; should try that too. Signed-off-by: Keith Packard

altos: STM i2c work.

2012-05-07T05:47:33+00:00

Start now driven by interrupts Send now done with DMA and interrupts Signed-off-by: Keith Packard

altos: Add STM I2C recv and stop funcs

2012-04-26T06:26:57+00:00

Recv doesn't appear to work with more than one byte Signed-off-by: Keith Packard

altos: Oopsed the STM DMA channels for I2C1

2012-04-26T06:25:43+00:00

TX is 6, RX is 7 Signed-off-by: Keith Packard

altos: Starting to write cc1120 driver

2012-04-17T18:01:18+00:00

This does "something" in radio test mode, appearing to generate a 730MHz signal. Signed-off-by: Keith Packard

altos: Correct STM USB driver

2012-04-14T21:04:29+00:00

Configure endpoint registers correctly now. Restructure code to make sure we send the right IN packets. Signed-off-by: Keith Packard
