* altos/lpc: adc code computes number of active ADC channelsKeith Packard2014-05-21
| | | | | | | Don't require the application to provide AO_NUM_ADC when AO_ADC_NUM is computed automatically. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: stm and lpc ao_boot.h were identical. move to kernel.Keith Packard2014-05-15
| | | | | | | These two files were absolutely identical, so share them by moving under kernel instead.x Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Use explicit boot loader signal in ao_boot_rebootKeith Packard2014-05-15
| | | | | | | | Instead of just "knowing" that ao_boot_loader will be passed zero when the application wants to get back to the boot loader, explicitly define the values so that both sides always agree. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Assume all LPC products will have 32KB of flashKeith Packard2014-05-12
| | | | | | | If we ever use something smaller than this, we'll need to figure out how to tell how much memory the device has. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Report battery voltage instead of S at startupKeith Packard2014-04-05
| | | | | | | This works on everything with a beeper except TeleMetrum v1.0 which just doesn't have enough flash space for the code. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Rename 'core' to 'kernel'Keith Packard2014-04-05
| | | | | | | core remains a bad name to use -- dirvish skips files (and directories, it seems) with that name. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Fix LPC LED driverKeith Packard2014-03-09
| | | | | | Was using wrong types Signed-off-by: Keith Packard <keithp@keithp.com>

| | | | 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>
* altos: Switch APRS to compressed position formatKeith Packard2014-01-14
| | | | | | This provides lat/lon/alt in fewer bytes while improving precision. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Turn on -Werror for STM and LPC buildsKeith Packard2013-12-20
| | | | | | | Now that the build completes with no warnings, make future warnings into errors. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Turn on warnings for LPC products tooKeith Packard2013-12-20
| | | | Signed-off-by: Keith Packard <keithp@keithp.com>
* altos/lpc: Missing */ in definition of PIO0_4Keith Packard2013-12-20
| | | | | | Would maek using these values pretty hard. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: lpc exti setup was incorrectly testing modeKeith Packard2013-12-20
| | | | | | Check for NOCONFIGURE bit was missing parens Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Clean up warnings for LPC productsKeith Packard2013-12-20
| | | | | | Unused varibles, functions and parameters. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos/lpc: Stop sending SETUP IN when the requested size is reachedKeith Packard2013-12-19
| | | | | | | | The host won't keep asking for SETUP IN packets once it has received the amount of data requested, so check to see if we've sent that much and flip back to IDLE state if so. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos/lpc: Reset less of the device on USB reset.Keith Packard2013-12-18
| | | | | | | | | | This leaves most of the device configured across USB reset, which appears to help when sending a IN reply to the first SETUP packet; without this change, the IN reply would always get a length of 0, which is fine for SET_ADDRESS, but not for GET_DESCRIPTOR_DEVICE, which OS X appears to send before setting the address (go figure). Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Build pdclib locally if necessaryKeith Packard2013-12-18
| | | | Signed-off-by: Keith Packard <keithp@keithp.com>
* altos/lpc: Be a bit more resistant to toolchain section name changesKeith Packard2013-12-18
| | | | | | | Just add some wild cards on the ends of each section name in case the toolchain changes names in the future. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Use all 16 bits of setup packet len when limiting reply lenKeith Packard2013-12-17
| | | | | | | | | We were only using the low 8 bits of the setup packet reply max len, which meant that if the other side sent a weird max len (as Windows 7 does), then we'd truncate our setup reply to whatever was in the low 8 bits of that value. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Change flash loader name to just AltosFlashKeith Packard2013-12-08
| | | | | | Remove the software version string from the product name Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Build .ihx files for all arm projectsKeith Packard2013-12-08

* altos: Use installed pdclibKeith Packard2013-10-10
| | | | | | Switch over to the installed pdclib everywhere 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: Rename easymini-v0.1 to easymini-v1.0Keith Packard2013-10-07
| | | | | | The production boards are the same as the modified v0.1 boards Signed-off-by: Keith Packard <keithp@keithp.com>
* altos/lpc, altos/stm: ARM requires ISB after switching stack pointersKeith Packard2013-10-07
| | | | | | | This sticks a barrier in the CPU to prevent using the wrong stack register past the change. Signed-off-by: Keith Packard <keithp@keithp.com>

| * altos: Wake up on LPC usart ISR only onceKeith Packard2013-08-25
| | | | | | | | | | | | | | Instead of waking up after every character, wait until the FIFO is empty to reduce overhead Signed-off-by: Keith Packard <keithp@keithp.com>
| * altos: Set default LPC stack to 512 bytes, Em to 384 bytesKeith Packard2013-08-25
| | | | | | | | | | | | | | The default for lpc has been raised to 512 bytes, but Em doesn't have enough RAM for that. Signed-off-by: Keith Packard <keithp@keithp.com>

| * altos/lpc: Stop using burst mode for LPC ADCKeith Packard2013-08-25
| | | | | | | | | | | | | | | | | | | | | | | | | | Burst mode doesn't stop after one round of conversions, so we end up getting incorrect values in whatever the last conversion register is. Just use single conversions and take an interrupt per channel. Also, slow down the ADC so that our values are more stable -- just need to make sure we get the whole conversion sequence done 100 times a second. Signed-off-by: Keith Packard <keithp@keithp.com>

* altos/lpc: Don't disable all interrupts when disabling one interruptKeith Packard2013-06-22
| | | | | | | | | The nvic iser and icer registers read value indicates all enabled interrupts, icer writes disable the set interrupts. Re-writing icer with the current value ends up disabling all interrupts, not exactly what we wanted. Signed-off-by: Keith Packard <keithp@keithp.com>

* altos/lpc: Get rid of ADC filterKeith Packard2013-06-17
| | | | | | | Now that the source of the Vcc noise has been identified, remove the unnecessary ADC filtering. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos/lpc: Get the IRC turned off after boot timeKeith Packard2013-06-17

* altos/lpc: Filter ADC inputsKeith Packard2013-06-15
| | | | | | | They're amazingly noisy on EasyMini, so just filter them as the only thing we use them for is battery and pyro numbers. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos/lpc: Make ADC inputs workKeith Packard2013-06-15
| | | | | | | They're still very unstable (bouncing around a lot), but at least they seem to report useful stuff now. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos/lpc: Force idle mode if USB gets an address during boot timeKeith Packard2013-05-19
| | | | | | This lets EasyMini be booted to idle mode by simply plugging it into USB. Signed-off-by: Keith Packard <keithp@keithp.com>
