@notdodgy glad for your interest, i havent't test Tello custom blocks on Fire yet, but i'm sure it work (tested the python code also on ESP8266). For the moment, if you prefer stay on uiflow setting on Fire, you might follow this step by step instructions on https://www.hackster.io/gperrella/m5-block-dji-tello-drone-control-c2646f . I explain how load tello.py directly at root of your firmware, then load custom block Tello5.m5b, only after that load the TelloTest5.m5f.
To embed firmly Tello blocks on the Fire firmware, we have to ask our friends of M5Stack, they only have the basic code to include on their micropython release. Hope is all clear, thanks again

i wonder if exists a command line to switch between the modes without act on display.
Thanks in advance

I would thanks again M5Stack crew to embed on third party block my TELLO code. Please find example code and docs in english (many thanks to Adam Bryant to edit it!) and italian version. M5stack-tello Hope help many of you to create very easily a lot of mission with this drone, Enjoy IT!

@kilam Well done, i have similar for STEAM project, i realized a grove interface for onewire ds18b20 to monitor water temp in an aquarium at the same time reading ENV II sensor

Maybe very interesting for STEM courses realize a sort of simulator like BBC micro:bitfor UiFlow (at least for the graphic UI)

Could help to understand the behaviour before to have the phisical device.
thanks

Hello, could be great to simply include/upload libs already shared for micropython (eg putting in a /lib path). It may expand a lot of capabilities (eg for HW ds18b20 or for SW Email sender etc). Better if Blockly section of UIFlow could accept some changes applied to Python section (at least the values)

@zontex thanks to answer, just to have confirm it is "safe" use a LDO to work at 3.3, i'm planning to connect one ENV II unit and at the same grove port A input pin 32 (or 33) of a Core 2. My doubt came from observe ENV unit schematic, where DHT 12 pin have pullup at 5V. Btw i don't have problem to put a LDO, my goal is share both sensors (one M5Stack and another external DS1820

Question: Grove PORT A for two sensors, i need to measure temp via 1-wire Ds1820, and Humidity, Pressure etc via i2c ENV II Unit. Someone has tried before? Further, is better use LDO (HT7533 or AM1117-3.3) to power DS1820, to avoid burn input pins (aren't 5V tolerant?). Any other minimal solution? (voltage divider etc).

@m5stack https://www.hackster.io/gperrella/m5-covid-bastion-074bb8 Hello this is my second project based on M5 ecosystem related to Covid solution to slow its spread. The main objective of this conceptual project is to demonstrate a way to control access to the offices of employees of a small company or members of an association.

Hello, here my project to contribute at this contest https://www.hackster.io/gperrella/m5-covid-sentry-a-covid-19-disease-monitor-479cd8
Hope it can help someone.
Project is still work in progress, stay tuned!
