@f3rn4nd0d I got "no module named 'wifisetup'" error, and without that, no 'strftime' in time... What am I missing in Mycropython for my M5Stack Gray? Thanks for your help.

you can try this pice of code which is working for me: . . #include <WiFi.h> #include "Free_Fonts.h" #include <M5Stack.h> const char* ssid = "your_host"; const char* password = "your_password"; WiFiClient client; void setup() { M5.begin(); // Connecting to WiFi: M5.Lcd.setFreeFont(FM9); M5.Lcd.setTextSize(1); M5.Lcd.setTextColor(TFT_WHITE); M5.Lcd.print("\n\nConnecting to "); M5.Lcd.println(ssid); WiFi.begin(ssid, password); while (WiFi.status() != WL_CONNECTED) { M5.Lcd.setTextWrap(true); M5.Lcd.print("."); delay(500); } M5.Lcd.println("\nWiFi connected"); delay(1000); M5.Lcd.fillScreen(TFT_BLACK); } void loop() { showWifiStrength(); delay(2000); } // show Wifi-RSSI level (signal strength in 4 bars + dBm ) void showWifiStrength() { int WifiRSSI = WiFi.RSSI(); M5.Lcd.fillRect(40, 0, 68, 15, TFT_BLACK); M5.Lcd.setCursor(40, 14); M5.Lcd.print(String(WifiRSSI) + "dBm"); if (WifiRSSI > -50 & ! WifiRSSI == 0 ) M5.Lcd.fillRoundRect(26, 1, 5, 12, 1, TFT_WHITE); else M5.Lcd.fillRoundRect(26, 1, 5, 12, 1, TFT_DARKGREY); if (WifiRSSI > -70 & ! WifiRSSI == 0) M5.Lcd.fillRoundRect(18, 3, 5, 10, 1, TFT_WHITE); else M5.Lcd.fillRoundRect(18, 3, 5, 10, 1, TFT_DARKGREY); if (WifiRSSI > -80 & ! WifiRSSI == 0) M5.Lcd.fillRoundRect(10, 5, 5, 8, 1, TFT_WHITE); else M5.Lcd.fillRoundRect(10, 5, 5, 8, 1, TFT_DARKGREY); if (WifiRSSI > -90 & ! WifiRSSI == 0) M5.Lcd.fillRoundRect(2, 7, 5, 6, 1, TFT_WHITE); else M5.Lcd.fillRoundRect(2, 7, 5, 6, 1, TFT_RED); }

To start understanding the functioning of the sim800l module I used the following example: //Reset resistance is not soldered. If necessary, weld it yourself. #include <M5Stack.h> #define RX_PIN 16 #define TX_PIN 17 #define RESET_PIN 5 void header(const char *string, uint16_t color){ M5.Lcd.fillScreen(color); M5.Lcd.setTextSize(1); M5.Lcd.setTextColor(TFT_MAGENTA, TFT_BLUE); M5.Lcd.fillRect(0, 0, 320, 30, TFT_BLUE); M5.Lcd.setTextDatum(TC_DATUM); M5.Lcd.drawString(string, 160, 3, 4); } void setup() { M5.begin(); header("SIM800L AT command", TFT_BLACK); M5.Lcd.setTextFont(2); M5.Lcd.setTextColor(TFT_WHITE, TFT_BLACK); M5.Lcd.drawString("Please use serial port to Test AT command.",0, 35, 2); // Host serial communication Serial.begin(115200); // SIM800L serial communication Serial2.begin(115200, SERIAL_8N1, RX_PIN, TX_PIN); pinMode(RESET_PIN, OUTPUT); } void loop() { //AT instruction write if(Serial.available()){ Serial2.write(Serial.read()); } //AT instruction result if(Serial2.available()){ Serial.write(Serial2.read()); } delay(10); } I sent some at command to understand if the module worked but apparently it doesn't work. Any suggestions?[image: 1585130692629-sim800l.png]

Great!

@skink said in UIFlow Handbook updated 01-March-2020: Wow, even if it is only in English, but it´s hammer the user manual, hats off to working. Thank you very much this is a super great manual with UI-Flow and Python examples. greeting skink Thank you for reading it, Other languages are planned, I'm just sorry that it is taking me so long to write it.

[image: 1582950983695-8433b3b0-3224-43f6-84f9-0a9a5c2e6030-image.png] it can display images without eraseing. (click OK)

@sysdl132 Great, i will take the time to try。

Pin 25 might work http://forum.m5stack.com/topic/1482/m5stack-with-external-speaker

Thanks for the heads up, looks cool. Will definitely try it out

HI @AndreaF the space is a little tight, but perhaps you can put it in sideways and solder things to the right place via a few extra wires. As you can see in the picture of env hat below, the SDA of your TOF module should be connected to pin G0 and the SCL should be connected to G26 [image: 1579658679155-env_hat_01-resized.jpg]

Thanks for the Twitter link, i've reached out to see if he can help. I did figure out how to do a rudimentary calibration by waiting for a button press and then setting the current values for roll and pitch to "offset" values and "correcting" subsequent readings using them. It works well enough for now, and I can calibrate in different orientations. The only issue now is that this just uses the magnetometer, I think... I'm only reading &roll and &pitch from IMU.getAhrsData(), i'm not reading the gyro values. So this is susceptible to motion, if I slide the unit from side to side on the table the horizon tilts when it should stay horizontal.

@robalstona Thanks, I did a try and it worked! However, line of code I got went through my wall ^^ Thanks
