RE: Please allow jtag or jtag over usb on next version
I don’t understand why you would want jtag when you can program OTA, USB and UART
RE: 328p firmware workflow
You need an external isp. If you have one of the Arduino products you can use them as a programmer via a program that is part of the default Arduino libs. For my servo module I use an Arduino 328p-pu which is the dip version and so I can just swap the ATmega chip out of the Arduino board and program it normally from arduino
RE: Base M5GO BOTTOM: Issues with UART (Port C)
You are using the M5Stack Fire?
Have you tried swapping the connections from UART1 to uart2
M5Stack Fire has occupied GPIO16 / 17 to connect with the PSRAM by default, it’s conflict with TXD / RXD (GPIO16, GPIO17) of GPS module. Therefore, when using the GPS module with the M5Stack Fire, you might have to cut the TXD and RXD from GPS module and wire fly to another set of UART pin, if you gonna use the PSRAM.
RE: New Products 05-July 2019 And new video series.
One can only assume that its because the risc V doesn't have built in wifi.
New Products 05-July 2019 And new video series.
M5Stack recently launched the new AIOT(AI+IOT) Camera powered by Kendryte K210 -an edge computing system-on-chip(SoC) with dual-core 64bit RISC-V CPU and state-of-art neural network processor.
M5stick-V AI Camera features its integration with machine vision capabilities, featuring the unprocessed acceptability to AI Visioning with high energy efficiency and low cost. We co-oped with Sipeed providing the MicroPython environment makes programming onM5stick-V easier.
The module comes with the OmniVision OV7740 sensor, using the OmniPixel®3-HS technology, providing a best-in-class low light sensitivity, making it ideal for machine vision. In addition to an OV7740 sensor, M5stick-V features more hardware resources such as a speaker with built-in I2S Class-D DAC, MEMS Microphone, IPS screen, 6-axis IMU, 200mAh Li-po battery, and more.
More than the visioning, M5stick-V also features the embedded APU - Audio Processor. With its hardware beam-forming support and dual 512-point FFT units, the M5stick-V is also capable of a series of machine hearing works like voice wake-up to speech recognition.

RE: Rotate UI object
@ajb2k3 I see an option to rotate a polygon under LCD.polygon, but I'm not seeing a GUI object rotation angle. Could you explain further?
When you add a label from the five icons above the Virtual M5Stack, a rotation block will appear in the UI Drop down menu.
RE: Adding external libraries via uiflow
Since m5stack moved from the Loboris fork of Micropython to the official Micropython v1.11 release, it seems the libs were also moved somewhere. With m5stack firmware v1.2.x, they used to be in /flash/lib, however now with firmware 1.3.x, that directory does not exist. If I try to create /flash/lib with ampy, the m5stack won't boot properly.
Internal FS (FatFS): Mounted on partition 'internalfs' [size: 2162688; Flash address: 0x1F0000] ---------------- Filesystem size: 2101248 B Used: 1400832 B Free: 700416 B ---------------- Traceback (most recent call last): File "boot.py", line 4, in <module> File "flowlib/uiflow.py", line 1, in <module> File "flowlib/m5stack.py", line 5, in <module> ImportError: no module named 'lib.speak' Traceback (most recent call last): File "main.py", line 17, in <module> NameError: name 'rgb' isn't defined MicroPython v1.11-112-g5f3c6ee93-dirty on 2019-06-26; ESP32 module with ESP32 Type "help()" for more information. >>>
The above serial output during bootup shows something in flowlib, but I can't seem to access it. If someone could assist with where to put the custom libs, I could probably get Blynk working again.
I thought that was just me. I too tried to copy over blynk this weekend using vstudio but again had the same boot issue.
RE: UIFlow Firmware, ToF unit and ampy
@hkubota You can send micropython code direct to the M5stack using the download and play buttons.
I have been doing things this way while testing the TOF with the I2C hub.
however, a better way is to use Visual Studio. see the video @lukasmaximus uploaded to the M5Stack youtube channel.
RE: [Solved]Fire, PaHUB, & ADC (ADS1100)
Just reached my knowledge of i2c and yeh found that the pullups have bee put on the hubs i2c lines as well as the line to the M5Stack port a.
nice but of bug fixing.
Just don't forget to put them back if you want to connect the ADC directly to the M5stack in future.
