| * altos/stmf0: leave ao_power_gpio names undefined without power managementKeith Packard2018-05-07
| | | | | | | | | | | | Should make it more obvious at compile time that you've done something wrong. Signed-off-by: Keith Packard <keithp@keithp.com>
* | altos/stmf0: Fix up USB debug codeKeith Packard2018-05-07
| | | | | | | | | | | | | | At least make it compile. In this configuration, it's dumping out IN3 endpoint register values. Signed-off-by: Keith Packard <keithp@keithp.com>
* | altos/stmf0: Add IN3 alternate endpoint supportKeith Packard2018-05-07
| | | | | | | | | | | | This adds the code necessary to drive another IN endpoint. Signed-off-by: Keith Packard <keithp@keithp.com>
* | altos/stmf0: Toggle IN2 SW_BUF bit when sending dataKeith Packard2018-05-07
|/ | | | | | | This tells the hardware we're done writing data to the second input buffer and allows it to be switched from NAK to VALID. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos/stmf0: Set 0x0 mapping to Main Flash for boot loaderKeith Packard2018-05-01
| | | | | | | | | When DFU finishes loading firmware and jumps to the application, it leaves the mapping of addresses starting at 0x0 set to System flash, which prevents the boot loader from receiving interrupts and requires a power cycle during flash & cal. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos/stmf0: whitespace fixKeith Packard2018-05-01
| | | | | | Trailing whitespace. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos/stmf0: Change tests for AO_BOOT_CHAIN and AO_BOOT_PIN to #ifKeith Packard2018-05-01
| | | | | | Were #ifdef, which meant that #define AO_BOOT_PIN 0 didn't work right. Signed-off-by: Keith Packard <keithp@keithp.com>

| | | | | | This way it can be incorporated into multiple operating systems more easily. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos/stmf0: Use double buffering for ChaosKeyKeith Packard2018-01-07
| | | | | | | This improves the USB performance of ChaosKey so that it doesn't NAK during data transfers at all. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos/stmf0: use double buffering for USB rx dataKeith Packard2018-01-07
| | | | | | This also allows us to stop shadowing USB rx buffers in system ram Signed-off-by: Keith Packard <keithp@keithp.com>
* altos/stmf0: Use double buffering for USB tx dataKeith Packard2018-01-07
| | | | | | | This shouldn't have much of an effect, but shows how double buffering works. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos/stmf0: Stop shadowing USB tx buffers in system RAMKeith Packard2018-01-07
| | | | | | Use the 16-bit USB memory directly, avoiding the buffer space and the copy Signed-off-by: Keith Packard <keithp@keithp.com>
* altos/stmf0: Remove packet counters from non-debug buildKeith Packard2018-01-07
| | | | | | These counters are only useful for helping debug the USB driver. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos/stm: Align 'data' to 8 bytes, just like textramKeith Packard2017-12-12
| | | | | | | | | | | | | | The textram section must be aligned to 8 bytes to keep the linker happy. However, if that section contains no data, the declaration will set the __data_start__ value to that alignment, but the data section itself would start on a 4-byte alignment, potentially 4 bytes lower than the value indicated by __data_start__. This completely scrambles initialized memory as the startup code will copy the data segment to __data_start__, 4 bytes off of the actual data segment start. Fix this by forcing the data segment to also be aligned to 8 bytes. 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>
* altos/stmf0: Initialize UART RTS/CTS before turning it onKeith Packard2017-06-27
| | | | | | If you try this after the UART is running, it won't work. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos/stmf: Fix up serial port flow control configuration bitsKeith Packard2017-05-15
| | | | | | | | | Compute whether any sw/hw flow control is in use. Compute whether hw flow control is in use as a separate value. These make the code a bit easier to follow. 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>

| | | | | | And allow application space to be limited to less than available flash. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos/stmf0: Fix HSI clock rate.Keith Packard2017-04-28
| | | | | | It's 8MHz, not 16MHz Signed-off-by: Keith Packard <keithp@keithp.com>

| | | | Signed-off-by: Keith Packard <keithp@keithp.com>
* altos/stmf0: Compute serial baud rate registers at runtimeKeith Packard2017-04-28
| | | | | | | This allows the system clock to vary at runtime, instead of requiring a fixed value. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos/stmf0: Not all timer configurations use AF2Keith Packard2017-04-24
| | | | | | Allow applications to select other configurations. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos/stmf0: Pull beeper pin low when beeper is offKeith Packard2017-04-21

* altos/lpc,altos/stmf0: Use -n flag to work around link editor issueKeith Packard2017-04-21
| | | | | | | | | Something changed in the link editor which makes it complain about 'no space for program headers' on LPC and STMF0 builds. Somehow, adding the '-n' flag to the linking step fixes it. It doesn't appear to break the build, so I guess it's ok? Signed-off-by: Keith Packard <keithp@keithp.com>
* altos/stmf0: Split up rom load in altos.ld to make linker happyKeith Packard2017-04-13
| | | | | | | The linker isn't happy when the .ld file tries to add text, the .exidx and .rodata segments in the same block. Split them up for success. Signed-off-by: Keith Packard <keithp@keithp.com>

* altos/stmf0: Add adc and beep support for TeleMini v3.0Keith Packard2017-02-20
| | | | | | | Note that the ADC code is running very slowly as required by the high impedance dividers on the TeleMini v3.0 pyro circuits. Signed-off-by: Keith Packard <keithp@keithp.com>
