I could wrote with parts from here and there my own code, without know absoluty nothing of coding. What I got: YOLO 20 CLASSES maix example but with all the features of StickV, as turn off,torch,etc. Draw the boundary boxes with better size and more clear bounds. Send via USB the coordinates,fps,class of the bboxes. Maix example only give FPS Any MOBILENET example code as 75 classes, or my own trained model keeping the features of the original firmware as Torch,buttons etc, as if you train your own model you lose that things. Send via USB Class of the object, fps and size of the inference (I think but not sure, I print kpu.foward (task, img) ) My trained model recognize all the kind of surface of my house, parquet, carpet,tiles, etc my rabbit and people. It works very nice. It is to pass that info to my robots. The think is I dont know what protocol use via USB, I think is Uart via VCP, but not sure. I would like to know the grove connector if is programble and how, pins 34 35, it should be possible, but no idea for what is used, if is fixed to I2C, SPI or what. Now what I want to know too is how get bbox in mobilenet models, it only give text, but dont draw boxes. Example of UART there is in the chinese version of MAIXPY wiki/ API. The web of training is just amazing and worth more that any support from MAIX, M5Stack should not leave the support in hands of Sipeed, their support and realibility is null. https://www.instructables.com/id/Object-Detection-With-Sipeed-MaiX-BoardsKendryte-K/ Follow this guy, he helped more that the own company, and check out all possible OPENMV IDE and forums, that is from MAIXPY was forked

@ruslancc Unknown but I have fixed that now. It could be that the M5Stick can not provide enough power for the heart rate monitor. You could try connecting one of these https://m5stack.com/collections/m5-accessory/products/grove-t-connector-5pcs-a-pack [image: GROVE-T_1200x1200.jpg?v=1566377200] between the Stick and the heart rate monitor and use the other connection to provide an additional power supply for the monitor.

Sorry, i have to give up on this. Something strange happened yesterday. After getting quite bad sound quality out of the node module i did something else and suddenly i heard a bang, followed by a strange smell. After unplugging and disassembling i found at least one capacitor dead in the module. [image: m9EnjH7FjSvm6JiY6] Have not decided if i salvage some parts or try to get at least the leds and the IR back into function ... currently it is just heating up when i power it.

You need to use a command line program called ampy to move the libraries across. This guy wrote a guide in which he used the standard micropython firmware and added his own libraries https://www.hackster.io/andreas-motzek/execute-logo-on-m5stack-esp32-basic-with-micropython-3713fd

Hey @Powersoft sorry for the late reply you can find the arduino code here https://github.com/m5stack/M5Stack/tree/master/examples/Unit/NEOFLASH

@Sebastian glad rick could help, I thought he might. Great work, if you get chance it would be nice to see a full guide on our hackster page hackster.io/m5stack

Then which one would work for me?

Do you use RFID unit or base

@koiexp I'm running it at 12v without any issues. Contact details - https://m5stack.com/pages/contact-us

@dda That would make sense now that I think about it as Wire is i2c0 which is routed to the grove port. Thank you for taking the time to work it out and solve it. BTW can you edit you title and put [Solved] at the beginning of the title to show that the issue is solved.

Thanks for your replies, i tried the proposed arduino example and unfortunately got the same results - no response from the bmm. I will contact the shop have a nice day Chris

Hi cncninja, currently the USB module hasn't been added as there are no micropython drivers for it. You can use the USB module with Arduino, there are a few examples and code on our docs page https://docs.m5stack.com/#/en/module/usb let me know if you get stuck
