Re: RP GPIO code to mycropython help request

Thanks Dave, The documentation for Pin Mode does not include Pin.OUT. Is it just not updated correctly or maybe there is another document I've not located? mode can be one of: Pin.IN - configure the pin for input; Pin.OUT_PP - configure the pin for output, with push-pull control; Pin.OUT_OD - config...

RP GPIO code to mycropython help request

The code below is for Rasberry Pi and I want to convert it for pyboard. #!/usr/local/bin/python # Run an eBay AD9850 on the RPi GPIO import RPi.GPIO as GPIO # setup GPIO options... GPIO.setmode(GPIO.BOARD) GPIO.setwarnings(False) W_CLK = 12 # Define GPIO pins FQ_UD = 16 DATA = 18 RESET = 22 def puls...

Re: DS3231 precision RTC driver

Sorry but I'm not quite clear on the RTC pull-ups. Is it necessary to remove the RTC pullup resistors for basic operation? Here is a description of the DS3231 with a Raspberry pi and shows the pull-up removal: http://www.raspberrypi-spy.co.uk/2015/05/adding-a-ds3231-real-time-clock-to-the-raspberry-...

Re: New pyboards

Is there a USA based store to purchase the MicroPython pyboard lite v1.0 ? Unfortunately, my company requires USA based company to purchase online.

ADS9850 DDS Signal Generator

I am planning to start integrating an ADS9850 DDS to the pyboard. If anyone else has experience with this board please respond.

Re: Driver for Adafruit GSM FONA module

Hello Damien,

Any further work on the FONA or other similar module? Did you develop a driver for it?

Thanks

Re: DS3231 precision RTC driver

This could be very helpful for my low power data loggers. Questions: 1. Did you need to remove the pull-up resistors on the SDA and SCL pins of the DS3231? 2. Can you recommend a supplier of the DS3231? 3. Can I still use a mosfet to cut power to the 3.3V DS3231 I2C chip to conserve power when I don...

GSM module recomendation?

If anyone can suggest a low power GSM module to use with the pyboard I would greatly appreciate it. I've read that one person is attempting to integrate the LoNet 808 - Mini GSM/GPRS. There is also the Adafruit FONA and probably many more. I need to be able to sleep the module and once per day trans...

Re: Ideas for next evolution of pyboard

Consider using the MCU:
Kinetis KL03 32 KB Flash
World's smallest MCU based on ARM® technology.
48 MHz Cortex-M0+ Based Microcontroller
Static power consumption as low as 2.2 µA with 7.5 µs
wakeup time for full retention and lowest static mode down to 77 nA in deep sleep
