@namazu2024 ちなみにですが、デフォルトで入ってくるサンプルプログラムではモバイルsuicaが読み取れました。

@namazu2024 こんにちは。
下記の投稿が参考になりますでしょうか？
https://community.m5stack.com/post/24081

また、これ以外で過去のバージョンではRFIDのブロックが上手く動かないのでI2Cを直接叩く方法もどこかで見かけたような気がします。

生データ表示(Write RAW Data）にて上手くいきましたのでご報告です。
下記の内容で無事期待通りの動作をしてくれました。

もしかしたらWrite Characterのバグ？の可能性があるかもしれません。

ありがとうございました。

@kimurer さん
コメント頂きありがとうございました。

ご教示頂きました方法で試してみたのですが、1桁目に"1"が表示されるのみとなりました。
当初私もコメント頂いた方法で試してみたのですが上手くいかず、試行錯誤の結果とりあえず2桁目までは表示できたのですが・・・と言った感じです。
生データの表示コマンド等もあるのでもう少し試行錯誤してみようと思います。

ありがとうございました。

Digi-Clockモジュールの3桁目・4桁目表示方法について

詳しい状況の説明

初めまして。
UIFlow2.0にて、Digi-Clockモジュールの3桁目・4桁目に1文字ずつ表示（Write Character）する方法がわかりません。
1文字目・2文字目は問題なく表示出来ます。また、文字列としての表示(Write String）も問題ありません。

Write Characterの表示位置指定は０～４までしか無いため、3桁目、4桁めは手動で5、7をそれぞれ指定しています。
添付のUIflowの場合、12:__表示の2秒後、34:__と言う表示になります。（1桁目、2桁目のみが更新され、3桁目、4桁目は消灯のまま変化なし）

毎回文字列を生成したうえでwrite stringによる表示としても良いのですが、更新時のちらつきを極力抑えたいため、write characterによる各桁個別の表示更新をしたいと考えています。

このような使い方の経験がある方がおられましたらアドバイス頂ければと思います。

使用しているUIFlowやArduinoライブラリのバージョン

• UIflow 2.1.1
• AtomS3 Lite
• Digi-Clock

@ajb2k3
Thanks for your reply.
I tried several times and found what am I wrong.

I was wrote only configuration with "Configure" button in M5burner.
Then it burned just only configuration but no other firmware.

So it should burn with "Burn" button. Then firmware and configuration were written correctly.

Thanks for your help.
Regards

Hello ajb2k3.
Thanks for your reply.

Yes, I erased before burnning.

The problem is no response when writing program into M5stack Basic with Web Terminal. (Just only displaying "Progress:" and progrss bar did not forwarding.)

It occures only combination with UIFlow2 and M5Stack basic.
(it is ok UIFlow1 and M5stack basic, also UIFlow2 and ATOMS3U is no probelm.)

Thus I assume UIFlow2 is not burnned correctly into my M5Stack Basic.
(In problem case, 24576 bytes was written. However other successed cases, 4186112bytes or 8384512 bytes written. I feel 24576bytes is too much small than oter cases. )

Also I tried to burnning UIFlow 2.0.3(4MB and 16MB) and 2.0.4(4MB and 16MB) with M5Burner but these were same result. (I tested UIFlow2.0. NOT UIFlow2.0 Fire)

So could you please let me know it you have any suggestions as to what shall I check?

Thank you
Regards

Hello

I tried to burn UIFlow2.0(v2.0.4-16MB) with M5burner but it seems not correctly burned.
Below is the result of M5burner. I feel M5burner burned very small amount.
(It wrote just only 24576bytes)
Also I tried to burn UIflow1, then it worked fine, no problem.
Additionally I tested with AtomS3U/UIFlow2.0.4. It also no problem.

Could someone please help me?
What settings should I check?
