Rename assembly dir to boot2, only has boot2.Ss (#230 )

Update tinyusb 1.3.0 (#228 )
* update included tinyusb to 1.2.0 move tusb_config.h from core to library for more portability * pump tinyusb * update tinyusb to 1.3.0 * try to fix ci warning

Earle F. Philhower, III	d67329a2b8	Rename assembly dir to boot2, only has boot2.Ss (#230 )	2021-06-30 08:42:13 -07:00
Ha Thach	3a9703fc20	Update tinyusb 1.3.0 (#228 ) * update included tinyusb to 1.2.0 move tusb_config.h from core to library for more portability * pump tinyusb * update tinyusb to 1.3.0 * try to fix ci warning	2021-06-30 08:22:36 -07:00
Earle F. Philhower, III	856b105ab9	Clean up include paths, remove duplicates/invalids (#229 )	2021-06-30 08:13:19 -07:00
Earle F. Philhower, III	03e740a511	Add CPU cycle counter accessors (#226 ) Use the 24-bit SYSTICK peripheral, wrapped in logic to extend it to a full 32 or 64bits. W/o the wrapper, SYSTICK will wrap around in ~100ms. Adds rp2040.getCycleCount() and rp2040.getCycleCount64() Clean up the libpico build process as crt0.S from the pico-sdk should be directly used. Clean up the keywords file.	2021-06-28 20:53:40 -07:00
Earle F. Philhower, III	e628c8e211	Upgrade Newlib to include 64-bit/8-bit %llu/%hhd (#227 )	2021-06-28 20:46:08 -07:00
Ha Thach	7eca6c609f	Use correct tusb_config.h for built-in usb (pico-sdk) (#219 ) Fix issue with usbd_desc_cfg value may not be initialized as zero.	2021-06-26 09:37:41 -07:00
Earle F. Philhower, III	f299120798	Remove accidental debug message	2021-06-25 18:47:02 -07:00
Earle F. Philhower, III	aac8146f00	Clear I2C status on short slave reads Fixes #222 The HW needs to have the TXC_ABRT flag cleared when a slave transmission is cut short by the master, or else it will effectively break the I2C bus and never recover.	2021-06-25 18:39:44 -07:00
Earle F. Philhower, III	35c974d4c0	Fix file creation on SD and SDFS (#216 ) The O_CREAT/etc. flags on the Pico are a full 32-bits in size, but the core was generating a flag for SdFat using an 8-bit type, so all the O_CREAT, O_TRUNC, O_APPEND, etc. flags got cut off. Fix the flag size. Fixes #214	2021-06-19 12:15:11 -07:00
Earle F. Philhower, III	27476815ab	Fix SerialUART flush (#215 ) Serial1.flush/Serial2.flush was not waiting for the proper FIFO to clear. Use the proper call from the Pico SDK. Thanks to Peter Remias for noting it.	2021-06-16 08:25:24 -07:00
Earle F. Philhower, III	b02b9c4be8	Add PDM library for Arduino Nano RP2040 Connect (#213 ) * Add PDM library for Arduino Nano RP2040 Connect * No PDM test in CI, only works on Arduino Nano RP2040	2021-06-16 08:17:09 -07:00
Earle F. Philhower, III	6afcf5881d	Initial Arduino Nano RP2040 Connect support (#212 ) Thanks to @Claupio for the bringup! Reference #208	2021-06-14 08:59:52 -07:00
Earle F. Philhower, III	30704a7c5e	Obey timeout value on SerialUART.read/.peek (#211 ) Fixes a hang when reading from the Serial UART ports because before the core would pause indefinitely for the next character. Now, wait up to Serial.setTimeout() milliseconds and if it times out return -1 to the app. Fixes #210	2021-06-13 14:11:23 -07:00
