Here is some testcode for everybody to get started in Platformio (Arduino)
- Unfortunately i could not get the i2S Dac output to work yet, maybe someone has a clue.
Private: Maker and Tinkerer
Profession: Prototype Engineer at Hutchison Drei Austria GmbH
I got my recent order today and instantly tested all components.
Unfortunately there is one issue in the ENV hat for the M5StickC.
The DHT12 sensor is working as well as the BMP280 but the bmm15 is not showing up.
A scan of the i2c bus shows that the device is not present at all.
I2C device found at address 0x5C ! (this is the dht12)
I2C device found at address 0x76 ! (this is the bmp280)
Found total 2 devices
Does anyone else have this issue and probably a solution before I contact the store for an itemreplace?
Unfortunately my tft cable got ripped off the pcb when i disassembled the m5stack (because i was nosey how my m5Stack is looking under the hood.
Currently I am using the damaged unit for another project where i don't want to have a display but all the other features.
I could not find any description or pinout for the display itself but would like to use it.
Can anybody please provide me a pinout diagram of the connector cable?
Thanks a lot
@ajb2k3 yes I did use the cooling module as well.
My thought was that there probably is some electrical interference when using the stepper and the servo module together. My solution in that case will be that i disconnect the mbus from the voltage regulator +wire completely to only power the steppers with the external power supply and do the rest with usb power to the m5Stack, so i am safe :D
It's definitely cooked :D I just do not understand what happened and don't want anybody to have a dead esp as well :D
Yesterday I got a nice package from m5 with my awaited Stepper and Servo modules which I need both for a project.
My first test was the Stepper-Module (with original power adapter) on a Fire and the provided test sketch.
It worked perfectly.
My Second Test was adding the Servo module as well and i combined Stepper and Servo test sketch.
It worked as well.
After combining the two sketches ,stacking Stepper and Servo board and connecting power nothing happened.
While disconnecting and disassembling again to check what could have gone wrong i burned my thumb on the really hot esp32 cover.
So obviously something has gone terribly wrong.
It seems that the fire is dead now and if i connect it to usb it gets hot again and does not do anything.
Probably somebody from m5 can check this - i don't want anybody else to have the same issue with a killed M5 Fire
That sounds perfect - yes i have an usb isp :D
Just a sneak preview of the animatronic robot (this is a "just for fun" project ...)
