我昨天託一位同事親到實體店買少量 m5stickC，但他撲了個空，他向鄰近的商家查詢，一位商家阿姨回了一句，這是「無人實體店」。 不會是吧？

我們是很認真的按照貴公司的回覆及指示，誠意地安排專人親到實體店購買，結果什麼都買不到！！！

不太好的體驗。

我託一位同事在官網買一支 m5stickC，而收件地址在香港，

但竟然從新加坡寄送過來，用了 15 天(半個月)另加運費。

但有一位居住深圳的日本朋友，親身到華強北實體店購買，往返花了 1 個小時。

我的問題是：

1. 貴司總部在深圳，購買者在深圳/香港，為什麼從新加坡出貨

   (明明我與 m5stick 的距離就是一小時生活圈內，但卻等待了 15 天 ?)

2. 我同事之前問過(但沒有回覆)，可否給予「深圳」或「香港」的實體購買店地址 ?

   (我想即買即用，因為不想等，不想額外運費)

I'm written several m5stickC demo with Arduino IDE.

Q. May I upload several binary files to m5stickC,

As well as, choose binary file I want to run when power on.

Hello,

I want to draw an image in m5stickC using Arduino IDE, but the image non-stop flash in screen.

void loop() {
// Change the sprite position
x = ...
y = ...

// Clear screen
M5.Lcd.fillScreen(WHITE);

// Redraw image to new location
M5.Lcd.drawBitmap(x, y, w, h,(uint16_t *)img, 0xffff);
}

Does m5stickC provide similiar functions / demo code:

1. double buffer
2. next frame checking --- lcd/cpu trigger to redraw

Thanks
Guy

I also used baud 75000, still can't install UIFlow firmware.

My install steps:

1. First, I press Erase button.
2. Second, I press Burn button & got following message:

Why I can't see UIFlow Logo when I first power on it.

What did I do wrong step?

@thrasher Absolutely 100% legal USB-C cable from product box.

As well as, I try to use my another PC (Win10) still can't identify.

This new m5stickC automatically run a testing program, How can I go to UI Flow Menu.

Thanks

I am a new user of m5stickC.

I use Win7 & installed CP210xVCP driver successful.

But still can't identify m5stickC always show unknown device in device manager.

Thanks
