It happened the same to me. No way to make it working with DHT11.
I use the dht11 shield from WeMos and D1 mini.

Can somebody confirm latest firmware and library work properly?

I'd give a try to ampy: ls *.txt | xargs -n 1 ampy --port /dev/ttyUSB0 --baud 115200 put (assuming all your txt files are in one directory) adjust port and especially baud to have the most reliability OR (with bash): for f in `ls *.txt`; do ampy put $f ; done; OR with webrepl (assuming 192.168.1.100...

Just a look at your code. In 4 nested loops how many times the condition is satisfied and the array growths? To check the problem I would put a stub (just a print?) instead of filling the array. If the problem is the same, we have an issue with urequests, otherwise it should be investigated how many...

@ernitron 1. Yes, using various HD44780s, 08x2, 16x1, 16x2, 16x4, 20x4, blue and yellow. 2. Yes, using both PCF8574 I2C backpacks and GPIO pins (4x data pins). ... Hi @mcauser, what a reply! I am flattered! I can't wait to assemble and test all this brilliant solution. Thanks... (just let me know w...

I have found this https://github.com/dhylands/python_lcd and looks pretty much what I was looking for.

Questions:
1. Did anybody make it working with WeMos D1 Mini?
2. Will it work in both i2c and GPIO modes?

I made some research but I have found little about LCD 1602 and micropython. I am looking for a simple library to pilot an LCD 1602 from WeMos D1 Mini (or other esp8266). Looking for simple API to send text on line 1 or 2, maybe adjust dim. Things like that. Are any problem to drive from the 5V outp...

I see. You have to consider that UART is asynchronous. So it can happen anytime and everywhere in your code causing exception. My routine is faulty as the ^C in your case happens during the time.sleep. I suggest: 1. Make the loop tight (i.e. substitute the time.sleep with pass) 2. try-catch all othe...

Am I doing something wrong? No I guess, not. I had the same problem. Looks like socket.timeout is not implemented (or is not the correct exception that upython throws on timeout). I simply catch everything and that worked for me. s = socket.socket(socket.AF_INET, socket.SOCK_DGRAM) s.settimeout(2.0...

Well, first of all thanks for giving a try to the patch for control-c. I think that should be included in the original firmware as it doesn't hurt ;) I think the problem is that the read will fail and exit before the 14th char can be read. Therefore I would try a loop like: chars = bytearray() while...

How about def read_temp(self): t = self.read_register(self.T_REG) return 0.00390625 * ustruct.unpack('>h', t)[0] @jimako the point being that ustruct performs the sign handling on a 16 bit quantity before it is reduced to 12 bits. Although the reduction to 12 bits is not explicit: it's subsumed int...
