• M5StickC (ESP32 based) gives psram error-infinite reboots

  in ESP32 • 1 day, 12 hours

  

  This is what I just started for a M5StickC:

  require('Storage').write('.boot1',`
  global.M5C = {
        BTNA: D37,
        BTNB: D39,
        LED: D10,
        IR: D9,
        lcd: {
          // AXP192: { id: 0x34 }, LD02: power lcd, LD03: lcd on
          power: (state) => { M5C.lcd.flipBit(state, 2); },
          backlight: (state) => { M5C.lcd.flipBit(state, 4); },
          flipBit: (state, bit) => {
              I2C1.setup({ scl: D22, sda: D21 });
              I2C1.writeTo(0x34, 0x12);
              buf = I2C1.readFrom(0x34, 0x12, 1)[0];
              if (state)
                  I2C1.writeTo(0x34, 0x12, buf | bit);
              else
                  I2C1.writeTo(0x34, 0x12, buf & ~bit);
            }
        },
        header: {
            Grove: [D32, D33],
            Front: [D26, D36, D0]
        }
    };`);
  

• Hardware?Schematics files for Bangle

  in Bangle.js • 3 days, 17 hours

  

  Hmm Bangle.JS is a DT NO1 F18 Outdoor-Sport Smartwatch from the shelf. Gordon has done many reverse engineering to make Espruino work on it. Browsing through the code you will find a lot details. The board file is a good starting point.

  I would say this is a good starting point

  https://github.com/espruino/Espruino/tre­e/master/targets/esp32

  this is a good starting point than dive into folder BLE

  and than check what's possible:

  http://www.espruino.com/Reference#Blueto­othDevice
  http://www.espruino.com/Reference#Blueto­othRemoteGATTCharacteristic
  http://www.espruino.com/Reference#Blueto­othRemoteGATTServer
  http://www.espruino.com/Reference#Blueto­othRemoteGATTService

  If you like you can share your tests so it could be added to this folder

  https://github.com/espruino/Espruino/tre­e/master/targets/esp32/tests

  @JumJum Do you have some test snippets you used during the implementation you like to share?

  If you get stuck, just ask.

  would be great if you check this issue and add things that are missing.

  You are welcome to fix issues for ESP32.

  Have a look at this module used for a specific hardware design as a starting point for creating a m5s, m5c or m5a module.

  Hi jeffmer,

  The M5StickC works well with Arduino...

  Do they run some init routine for the AXP192?

  For Espruino it is possible to convert cpp code into a APX192 module. If this is helps to get ride of those reboots.

• Weak bluetooth signal

  in Bangle.js • 2 weeks, 6 days

  

  Noice is also produced by usb chargerd without a load, because the are all switched.

  so better unplug them if not used ;-)

• How can I listen the WIZnet module and catch its errors?

  in Other Boards • 3 weeks, 4 days

  

  Well the W5500 implementation is missing a getStatus() so it is not possible at the moment. If go to the datasheet you will find the reset pin, which needs to be triggered to reset the device.
  Check this question on githup.
