@m5stack I do have some tools. Are there any instructions in that case? Thank you!

could you try to use baud rate 115200.

Thanks for the reply. Got the Arduino library example to work. Looking forward to a UIFlow fix. See my review at: Another Uncontrollable Bug: BugC from M5Stack: https://www.facebook.com/thomas.andrews.357/media_set?set=a.2587374321367103&type=3

It will be best if the sensor is connected 5-10cm away from the device. The sensor connected directly to the connector will be heated by the device through paths and goldpins and you can not help it.

As far as dht11 / 12 is concerned, I already subtract these 2-3 degrees in the program from the read temperature, which are overstated. But you have to check it yourself experimentally if the result is overstated with any other sensor in the temperature range you want to measure.

Unfortunately, I don't have dht22, so I won't tell you anything specific about its accuracy or results.

@m5stack This means that when the Stick is plug to the 18650C accessory, the 18650C accessory will not charge the internal battery?

Thanks! it works.

Hi again ajb2k3,
I am not sure why but it does not seem to work with my set up.

Here is the code I am using for the stickC to trigger camera. Where would I put the code you suggested? Thanks in advance!
#include <M5StickC.h>
#include <BlueMagic32.h>

#define LED_PIN 10
#define TRIGGER G0

void setup()
{

M5.begin();
Serial.begin(115200);

pinMode(LED_PIN, OUTPUT);
digitalWrite(LED_PIN, HIGH);

BMDConnection.begin("BlueMagic32");
BMDControl = BMDConnection.connect();

M5.Lcd.setTextColor(TFT_WHITE);
M5.Lcd.setTextSize(2);
M5.Lcd.setRotation(3);
M5.Lcd.fillScreen(TFT_BLUE);
}

void loop()
{
// read data
int value = digitalRead(36);// read the pin(0: not detectd 1: detected)
M5.update();

if (M5.BtnB.wasPressed())
{
ESP.restart();
}

if (BMDConnection.available())
{

M5.Lcd.drawCentreString(BMDControl->timecode(), 80, 34, 2); if (M5.BtnA.wasPressed()) { BMDControl->toggleRecording(); } if (BMDControl->isRecording()) { M5.Lcd.setTextColor(WHITE); digitalWrite(LED_PIN, LOW); } else { M5.Lcd.setTextColor(TFT_GREEN); digitalWrite(LED_PIN, HIGH); } M5.Lcd.fillScreen(TFT_BLACK);

}
if (M5.BtnA.wasPressed())
{
BMDControl->toggleRecording();
}

if (BMDControl->isRecording()) { M5.Lcd.setTextColor(RED); digitalWrite(LED_PIN, LOW); }

}

Thanks for the hint. I got the script working now!

I made these examples quite some time ago https://github.com/m5stack/M5-ProductExampleCodes/tree/master/Core/M5Stick/Arduino using u8glib library to display text is quite easy but I could never get my head around the glyph drawing

@noiseislife

With a little "wait_ms()" its more clear what you mean :-)

from m5stack import * from m5ui import * from uiflow import * setScreenColor(0x111111) label1 = M5TextBox(05, 05, "a", lcd.FONT_Default,0xFFFFFF, rotate=0) label2 = M5TextBox(05, 20, "x", lcd.FONT_Default,0xFFFFFF, rotate=0) label0 = M5TextBox(16, 50, "A", lcd.FONT_DejaVu72,0xFFFFFF, rotate=0) for angle in range(91): label0.setRotate(angle) label1.setText('angle:' + str(angle)) wait_ms(50) for posX in range(16, 256): label0.setPosition(x=posX) label2.setText('pos-x:' + str(posX)) wait_ms(100)

I am sure it is ones more a bug :-)
You can check this, if you let the angle zero. You can see that the char disappears at pos-x = 33. And the same behavior occurs, if you have rotated the char. It is obviously one more of the uncountable bugs.

@M5Stack: Why does the M5Stack not draw a char if a small part is outside of the screen? We can display a char half way, if it is rotated, but not if it is at angle 0 degrees. That makes no sense. Maybe someone would like to program a scrolling text so that chars appears on the right and disappears on the left.

Best regards
Thomas

You can also check out the wiki page on uiflow github page, it's pretty old and a lot of things are missing but you may find what you are looking for there
https://github.com/m5stack/UIFlow-Code/wiki/M5UI

@noiseislife Glad you got to the bottom of it.
I keep forgetting that option.

My earth unit can work on stickC with analog reading.

(Maybe is G33)

#define analogpin 33 //maybe it's 32

I was able to get a simple example of turning the stick LED on and off with a slider switch. You need to alter the coordinates and size of the qr in order to make it visible on the screen

Response is a little slow though, you may want to try IFTT or try to use http request and control from the browser or make an app with mit app inventor, I made a guide here a while ago, It's using arduino but I hope to do an updated version once I get an android phone. https://www.hackster.io/lukasmaximus89/m5stack-and-mit-app-inventor-47bd32

@ajb2k3 that worked, thanks

@clocey 5V to 5<- (pin 8) and gnd to gnd (pin1)

Thanks lukasmaximus and m5stack. Combining the two answers solved my problem. Split the work over two cores and added a suggested delay between calling M5.BtnA.wasPressed() and it seems to work as hoped for. Did not use the interrupt solution though interesting.

what kind example are you need ? if just Arduino example code. you can find it on our Github page
