The code above is for the maixpy (micropython) not arduino

Hi, in order to help you , we need to see the code

Not possible, i had problems with rasp pi since the firmware/drivers used on those cameras are finicky

uhm, the mic has a design flow

1. M5StickV will not have Microphone function, which doesn't affect the normal usage;
2. For customers who do need this function, pls contact your purchased channel for after service, till Sep. 30;
3. M5StickV+ will be released end of 2019, adding Wifi and Microphone function.

@borisu
Please provide the code you upload

done, used party code from anoken who sourced it from the arduino version , i clean up and updated it

im not sure i understand, can u provide an example ?

EDIT: it works now i have to comment out those two:
#pmu = axp192()
#pmu.enablePMICSleepMode(True)

when added they the IMU locks up

new bug:
"pmu import axp192" interferes when i try to get gyro/accel data from the MPU6886

https://m5stack.hackster.io/anoken2017/cheering-watch-of-m5stickc-v-34f0cc

Near the end , tell us if it helps

@xeon sorry for resurrecting old post, i had the same problem, i currently close getting data from the IMU

Hey
While those parameters exist on the vanilla micropython (openmv), StickV uses a modified version of micropython (that comes with the firmware) if you need to do you have either 1. work around it (flip image instead of text ) or 2. compile your own firmware and upload it on the stick

btw here are the values you can use on the stickV : https://maixpy.sipeed.com/en/libs/machine_vision/image.html#imagedrawstringx-y-text-color-scale1-xspacing0-yspacing0-monospacetrue

I just generated a model using v-training , then tried to use yolo instead of fmap=kpu.forward(task,img) since i like to know the position of the object
but the script stops working.. any help?

4,8 X 2,5 X 2,3 cm

Not dead, the grove connections are not soldered

@ajb2k3
dunno, i just started testing it, my first test was to find the Voltage output and couldnt find it then tried all the methods above, among others flashing the latest firmware, unless the grove port is disable via software the port could have been dead from factory

yelp mine grove port is dead, tested multiple times with a i2c IPS display and a i2c scanner on Maixpy only get 2 devices and not a 3rd [0x34 & 0x68] also not getting any voltage output and also tested with a different power source on the IPS display but still not getting detected, this just sucks cause i had plans :(

@ajb2k3
yes, cant seem to find info on it

EDIT: i started testing the pins and i cant detect a voltage output

@ajb2k3
4pin expansion PH2.0-4

Can anyone point me on how you use the expansion slot?

@thrasher
i also did for me because maix editor fixes the whitespacing before uploading, if you edited the file in text mode like me you probable added some wrong whitespace character without knowing
