  So my first steps in setting up a project with M5Stack AWS on my Mac OSX Big Sur (11.6). Installation of visual studio seems okay. When compiling the AWS IoT EduKit Getting Started PlatformIO Configuration File I get this error message

  @liemph

  Fire Has PSRAM .. use Port C PIN ..
  so it can't use Port C .

  Fire 는PSRAM 이 있어요 그것이 C 포트에 GPIO를 사용합니다.
  그래서 C 포트를 사용할수가 없답니다.

  Burn of UIFlow2 (v2.2.4-16MB) to M5Core-Grey using M5Burner loads stub but not full firmware. Burn of UIFlow_M5GO (same M5Burner) works fine. The UIFlow2 burn results in inoperable M5GO even though final message says 'Burn Successfully, click here to return'.

  Here is screen shot of output from Burn:

  --chip auto --port /dev/tty.usbserial-01DB92E6 --baud 1500000 --before default_reset write_flash -z --flash_mode dio --flash_freq 80m --flash_size detect 0x9000 /Applications/M5Burner.app/Contents/Resources/packages/tmp/uiflow2-cfg.bin

  I am writting the lcd driver for the m5stickc.
  There are many libraries exist for m5stickc lcd display, but the parameters for those power voltage settings are variant, some lib even send more parameters than the register required.

  for example, in lib m5stickc
  it send to register ST7735_PWCTR1 with 3 parameters [0xA4, 0x04, 0x84]

  but in the datasheet st7735sv

  the register PWCTR1 only accept 2 parameters.

  in the comment, it said "-4.6v" .
  but the 2nd paramter 0x4 is indicate "-4.5v"

  for lib M5GFX, src/lgfx/v1/panel/Panel_ST7735.hpp
  class Panel_ST7735S.
  it still send to register CMD_PWCTR1 with 3 parameters [0xA2, 0x02, 0x84]

  so what is the correct value for those voltage (VGH, VGL, AVDD, GVCL, GVCD)

  I can't find the schematic of m5stickc, so I can't find the right value for those voltage.

  in the datasheet st7735sv , page 165,
  it said "The deviation value of VGH/ VGL between with Measurement and Specification: Max <= 1V".

  I just got the M5GO Kit, and I'm trying to make a Voice Assistant. For some reasons, the Demo of the kit made me think that accessing the microphone is easy. But, after hours of finding, it seems that there is no library or support for the kit to record audio. Does anyone have any resource regarding this?

  Problem:

  Der Schrittmotor funktioniert nur korrekt in der Z-Achse bei normalen (langsamen) Drehgeschwindigkeiten.
  Beim Versuch, die X- und Y-Achsen zu verwenden, funktioniert der Motor nur, wenn ich die Vorschubgeschwindigkeiten auf das 10-fache oder höher erhöhe.
  Wenn ich versuche, die Adresse auf 0x71 zu ändern, wird das Modul nicht erkannt.

  @samantha_martin Hola Samantha. El M5StickC Plus (SKU:K016-P) utiliza el chip ESP32-PICO-D4, que integra Bluetooth LE. Para reducir la latencia en la transmisión HID, puedes probar las siguientes acciones:

  Optimizar la frecuencia de envío de datos: En las librerías ESP32-BLE-Keyboard o BleGamepad, ajusta el intervalo de notificación BLE a un valor más bajo (por ejemplo, 10-20 ms). Algunas librerías permiten configurar esto al inicializar el dispositivo HID.

  Minimizar el código en el loop(): Asegúrate de que no haya delays innecesarios ni tareas bloqueantes (como impresiones Serial) que ralenticen la detección de botones y el envío de comandos.

  Configurar el modo BLE de bajo consumo: Aunque el ESP32-PICO-D4 es eficiente, verifica que no se encuentre en modos de suspensión prolongada. Asegúrate de que el dispositivo BLE esté configurado para enviar notificaciones inmediatamente al detectar una pulsación.

  Actualizar el firmware del ESP32: Usa la última versión del core ESP32 en Arduino IDE, ya que a menudo incluyen optimizaciones en el stack BLE.

  Verificar la configuración de Android: En el menú de configuración de Bluetooth de tu teléfono, desactiva opciones como "Ahorro de batería" para el dispositivo M5StickC Plus, ya que pueden restringir la frecuencia de actualizaciones HID.

  I should note that I am also using the SD card interface and whenever the SD is not detected on power up the display doesn't work either. I believe they are on the same bus.
