Re: TinyRTC I2C Module DS1307 + AT24C32N
continuity appeared fine. With a more detailed search around I found others complaining of similar problems . In common with the author of the link, the D1 diode was defective on both my shields. I removed the diode and resistor R5 completely and the RTC module now works. As the IC appears to be ok ...

Re: TinyRTC I2C Module DS1307 + AT24C32N
it was 2.85V, so I put in a brand new CR1220 which read over 3V. Unfortunately this has the same result.
I repeated this on a second tiny RTC clone with the same outcome.

Re: TinyRTC I2C Module DS1307 + AT24C32N
sorry to add to an old thread, but it seems relevant. I am using a clone TinyDS1307 with a WEMOS D1 mini Pro ESP8266. All works well but the RTC time does not survive a power reset. setting ds.halt(False) has the same outcome. I have tried the same code with the uRTC driver too with the same result....

rshell connecting to Pycom boards using Pybytes firmware
This question relates to using Rshell tool with Pycom boards flashed with Pybytes firmware. I recently started using Pycom's Pybytes firmware on a Pycom devboard (LoPy) and unfortunately Rshell is no longer able to connect. ls /dev/tty* returns the correct port. However rshell --buffer-size=30 -a -p...

Re: MicroPython IDE
I think the lack of a strong IDE is a real barrier to entry to using Micropython (particularly for beginners). As a hacker-level maker (non commercial) I personally use Atom on linux Ubuntu to write code and manage small projects. I can also directly interface with the REPL using Pycom's PYMAKR Atom...

Re: Cant access REPL
OK @chromecat step by step: 1) when you installed the firmware using esptool.py what message was displayed in the Terminal? Did you erase_flash first before you write flash the firmware? What speed (baudrate) did you use? Try it at 115200. 2) How are you trying to access REPL? Using PUTTY on Windows...

Re: MicroPython AP spotted in the wild
Perhaps RailCorp are trialing some on-board sensor network options?

Re: MicroPython Newsletter Issue 3
thanks for the in depth update @Damien, this looks an extremely exciting application and development of Micropython.

unable to revert to main filesystem
I am running a uSD card shield on a esp8266 devboard I am able to mount the SD card using import machine, sdcard, os sd = sdcard.SDCard(machine.SPI(1), machine.Pin(15)) os.umount('/') vfs=os.VfsFat(sd) os.mount(vfs, '/sd') os.listdir() I can then open and append files in the /sd directory. However I...
