* altos: add ao_time_ns APIKeith Packard2019-02-25
| | | | | | | This provides nano-second resolution times by reading the systick value (which runs at 250ns ticks on stm). Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Fix several mis-specified time typesKeith Packard2019-02-25
| | | | | | Make sure AO_TICK_TYPE is used "everywhere", instead of uint16_t or other. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Fix ISR declarations to make them non-weakKeith Packard2019-02-21
| | | | | | | | | | In my zeal to eliminate warnings, I added declarations of all ISR functions to a shared header file. However, I managed to include the 'weak' declaration, which meant that the intended ISR functions were as weak as the 'default' ISR functions. This left all interrupts non-functional, which doesn't make for a happy program. 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: Add -Wshadow to CFLAGSKeith Packard2019-02-18
| | | | | | And fix up the related messages. Signed-off-by: Keith Packard <keithp@keithp.com>
* stm: Expose LCD font API in ao_lcd_font.hKeith Packard2019-02-18
| | | | | | | That required renaming the existing LCD font defintions from ao_lcd_font.h to ao_lcd_font_bits.h. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Add a pile more compiler warningsKeith Packard2019-02-18
| | | | | | | | | | | Adds: -Wpointer-arith -Wstrict-prototypes -Wmissing-prototypes -Wmissing-declarations -Wnested-externs 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: Remove unused ao_adc_get from ao_adc_stm.cKeith Packard2019-02-18
| | | | Signed-off-by: Keith Packard <keithp@keithp.com>

* altos: Mark local functions 'static'Keith Packard2019-02-18
| | | | | | Working towards supporting -Wmissing-prototypes Signed-off-by: Keith Packard <keithp@keithp.com>
* altos/stm: Note that ao_i2c_recv_dma_isr isn't actually usedKeith Packard2019-02-18
| | | | | | | | | This function resets the i2c transceiver after DMA completes, but it hasn't ever been hooked up. Some testing would be a good idea. For now, just add a comment and mark the function as referenced to avoid a compiler warning. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos/stm: Support SPI modes other than 0Keith Packard2018-10-19
| | | | | | ADXL375 requires SPI mode 3. Signed-off-by: Keith Packard <keithp@keithp.com>

| | | | | | And update all users to be explicit about the desired config. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Create ao_data_fill shared functionKeith Packard2018-10-19
| | | | | | | This fills a data ring entry with all of the current sensor values other than the ADC. It is used in all of the adc completion functions. 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: Use stdbool true/false instead of TRUE/FALSEKeith Packard2018-10-13
| | | | Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Make cmd number parsing functions return valueKeith Packard2018-10-13

| | | | Signed-off-by: Keith Packard <keithp@keithp.com>

| | | | | | Stop using pdclib Signed-off-by: Keith Packard <keithp@keithp.com>
* altos/stm: Make flash loader work with either 8MHz or 16MHz xtalKeith Packard2018-10-13
| | | | | | Provide PLL definitions for both values. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Allow timer interrupt without needing tick countKeith Packard2018-08-15
| | | | | | | This saves a bit of space in the fox1ihu loader which uses the timer interrupt to poke the watchdog. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos/stm: Let products override AO_LED_TYPE for stm processorsKeith Packard2018-06-17
| | | | | | No need requiring it to be uint16_t Signed-off-by: Keith Packard <keithp@keithp.com>
* altos/stm: Define ADC channels for TEMP and V_REFKeith Packard2018-06-17
| | | | | | These are fixed at 16 and 17. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos/stm: Remove unused ADC names from ao_adc_single_stm.cKeith Packard2018-06-17
| | | | Signed-off-by: Keith Packard <keithp@keithp.com>
* altos/stm: Enable HSI timer when HAS_ADC_SINGLE is setKeith Packard2018-05-28
| | | | | | The ADC unit always uses the HSI timer. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos/stm: Add polling ADC sampler APIKeith Packard2018-05-28
| | | | | | | This just fetches ADC values on demand instead of loading them periodically into a ring buffer from the timer interrupt. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos/stm: Add per-LED port/pin mode in LED codeKeith Packard2018-05-16
| | | | | | | | | If you've got a complicated LED pin arrangement, you can ask for each one to be configured separately, instead of using groups in a couple of GPIO registers. The code isn't as efficient this way, but at least it's easy to read. Signed-off-by: Keith Packard <keithp@keithp.com>
* Remove ao_radio_cal from stm products without radiosKeith Packard2018-04-26
| | | | | | Products without a radio don't need this value. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos/flash-loader: On STM, don't include ao_usb_disableKeith Packard2018-04-26
| | | | | | This saves a bit of space, keeping the flash loader under 4k on fox Signed-off-by: Keith Packard <keithp@keithp.com>
* altos/stm: Simplify ao_usb_write a bitKeith Packard2018-04-26
| | | | | | | Remove unnecessary 'offset' param (was always passed zero). This also makes some code conditional on that value no longer necessary. 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: Actually store current MPU9250 data in data ringKeith Packard2017-12-11
| | | | | | | The ring is updated when the ADC finishes; all of the other sensor data needs to be copied in at that point. 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>

| | | | Signed-off-by: Keith Packard <keithp@keithp.com>
* altos/stm: Add AO_EXTI_MODE_PULL_NONEKeith Packard2017-11-11
| | | | | | This is clearer than using '0'. Signed-off-by: Keith Packard <keithp@keithp.com>

| | | | 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: 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>
* stm: Add more mask-based GPIO controlsKeith Packard2017-04-04
| | | | | | | Lets cortexelf do more things with groups of pins, rather than one pin at a time. Signed-off-by: Keith Packard <keithp@keithp.com>
