There is a new Moteino Arduino core package release (v1.4.0). If you’ve used the Moteino package so far with the Arduino IDE, you should get a little notice next time you start it up. By the way the link to the LowPowerLab package definition JSON is the same and should be pasted in your Preferences dialog under Boards Manager URLs:
Then you can either install or upgrade to the latest AVR package. Notice there is a brand new Moteino SAMD package with a new MoteinoM0 board as well, more on that in a separate post. Install/upgrade these in your Boards Manager:
These two packages includes a refined selection of taget boards:
- [ Moteino / Moteino-USB ] – use this to send your sketch to a Moteino or MoteinoUSB
- [ Moteino (8Mhz) ] – for 8Mhz Moteinos
- [ MightyHat ] – technically identical definition to Moteino but use this to target a MightyHat
- [ MoteinoMEGA / MoteinoMEGA-USB ] – use this to program MoteinoMEGA or MoteinoMEGA-USB
- [ MoteinoM0 ] – a new Moteino based on SAMD21 Cortex M0+!
Once the packages are installed or upgraded you should see these new boards in your Tools>Boards menu:
And if you’re using my custom IDE board/port shortcut bar add-on, you can quickly add and access them directly from a click of a button, no more searching in the mile long Boards submenu of doom:
Some notable changes in these new packages:
- added standard LED_BUILTIN pin macro definitions for all boards, you can simply use this macro to address the onboard LED of any Moteino, no more need for specific checks of what board it is you’re targeting, the LED_BUILTIN will just work. This macro references D9 on 328P Moteinos and MightyHat, D15 on MoteinoMEGAs, and D13 on MoteinoM0, simply use this macro directly in your sketch:
- added board macro definitions for all Moteino boards:
- added SS_FLASHMEM macro pin definitions for all Moteinos, again this is to ease the use of the SPI CS/SS selection pin across all Moteino boards:
I hope you find these changes useful. There’s lot of work to be done to upgrade all the sketches in the RFM69 and SPIFlash libraries to make use of these new macros. Please report any issues and stay tuned for the coming updates on MoteinoM0!
Does LED_BUILTIN and SS_FLASHMEM macros then mean that this code is not needed anymore?
#ifdef __AVR_ATmega1284P__
#define LED 15 // Moteino MEGAs have LEDs on D15
#define FLASH_SS 23 // and FLASH SS on D23
#else
#define LED 9 // Moteinos have LEDs on D9
#define FLASH_SS 8 // and FLASH SS on D8
#endif
Yes exactly!
You would only need those if you have another board (not Moteino) with the same processors and need to make some pin decisions based on different CPUs. But these sketches were designed for Moteino from the beginning so now it’s easier to simply use the Moteino pin macros, to clean up some of those convoluted checks.
