Re: [SOLVED] DS3231 uRTC set / read problems

But i'm not able to use it to set/read alarm, is it a known issue ? I set the alarm with : rtc.alarm_time((2017,...

mikruth, no, I'm sorry and I tried many things ; To sum up : I'm using 1.8.7 >>> i2c.writeto_mem(0x50, 0, bytearray([104, 101, 108, 108, 111, 32])) >>> i2c.readfrom_mem(0x50, 0, 11) b'Qc\x83`\xc9<\x0e\xa3\xb6\xc9\xae' >>> i2c.readfrom_mem(0x50, 0, 11) b'hi]\x985\x07\x9a}}\x05!'

Re: I2C EEPROM on uPy/ESP8266?

Hello,

Hmmm, I'm using this kind of module;

My guess is I don't need pull-up resistor. I'm right?

Re: I2C EEPROM on uPy/ESP8266?

Hi Guys, I've just received my 24c356 and I'm unable to use it with mcauser code. I use a Wemos D1 mini, VCC is connected to 3.3, when I scan i got : 80. Something's weird, when I try to write values in the EEPROM and then I try to read twice the results I got 2 different results : >>> i2c.writeto_m...

Re: Saving power

Hello,

I'm still looking for a way to shutdown/disable Wifi on the ESp8266 with microPython. If I've read this topic correctly I guess I can't.

Is there an update ?

Thanks

Share the result if you give it a try !

Re: Running out of memory w/ API requests

Hello, I didn't have a close look to your code but, I'm experiencing the same behavior with API's (google, openweathermap) AND an OLED screen. As I understand it's a heap problem (something like a lack of "working" memory). I bought a Wemos Mini pro with 16Mo of memory but the built version of Micro...

Re: REPL Doesn't Work

Make sure you have flow control disabled. You were right ! I had to disable Hardware FC to make it work on the D1 mini pro. But not with the D1 mini. Can you try "screen /dev/ttyUSB0 115200" instead of minicom? Does that work better? You were right too ! It works, sorry. Do you know where does this...
