Hi Pyth, I use the pyboard with her housing... So, X or Y position produce same result. I can pass 2 littles wires by bottom of housing. But result isn't convenient... with a "flying" coin cell. I will try to solder directly a coin cell "breakout" under the board, ... space could accept a coin cell....

Hi, I use my pretty pyboard with her housing and lcd160. The result is clean. I can connect properly serverals sensors on Y part without ugly wire. It's perfect. Beautiful and convenient. But, I need to use vbat for saving time, and I have found a big problem for connect a coin cell properly. I have...

Hi, Everything is resolved... This script looks works fine with lcd160 too... from machine import I2C from ads1x15 import * from time import sleep import lcd160cr i2c = I2C(2) adc = ADS1115(i2c = i2c, address = 72, gain = 4) lcd = lcd160cr.LCD160CR('X') lcd.set_orient(lcd160cr.LANDSCAPE) lcd.set_tex...

Hi, I'm using a MICS-6814 sensor (from china) which indicate 3 gaz concentrations (N02, NH3 and CO) by a analog sensor... on a pyboard. Output voltages are very lows. So, I use a ADS1115 amplificator. The result looks good. But, I have interrogations about NO2 sensor. The datasheet of the sensor : h...

Hi,

Yes for sure.

So, how can I change this sgp30 lib for that it works with a pyboard?

Thanks.

Hi, I use the only one library that I have found for sgp30 and micropython: https://github.com/alexmrqt/micropython-sgp30 ... Maybe you have an other one which wok fine, like for uv sensor that I can use now until I have found a good advise in this forum about this uv sensor, which need an other lib...

Hi Peter, Thanks for your availability. I have tried yet a command with i2cmachine without master parameter, but it doesn't works. The sensor isn't initiate on i2c canal. I have tried too this solution : https://forum.micropython.org/viewtopic.php?f=6&t=3250&p=24707&hilit=i2c+pyb+machine#p24707 . It...

Hi, I have tried to use the sgp30 sensor from adafruit... with a pyboard. So, I have download the sgp30 lib from github, which indicate a procedure of installation with a i2c.MASTER command, and after, when the sensor is initiated, have to accept a "writeto" command. I have use the i2c's machine ins...

Hi, I have tried to save data from the original tile sensor... And discover in same time the behaviour of pyboard d (I have used pyboard classic yet)... Maybe I don't understand something, but the exemple of upython site doesn't works for me. I don't know why, but it appears that there is a confusio...

Hi Jonnhy, How do you check your sdCard? For "seeing" it, the way is different from with classic pyboard... With my poor knowledge, I know 2 ways : - with a repl session - with a boot.py wich contain command for usb mod AND command to mount sd card. If you need more info about commands under repl se...
