Scrolling text smartmatrix dan Rtc DS3231 tampil bersamaan

SmartMatrix Display
1

hai, salam kenal salam sejahtera.
sebelumnya saya minta maaf karena saya benar-bnar pemula.
semoga dikomunitas ini saya mendapatkan pelajaran baru dan bimbingan. Saya sedang mencoba belajar library SmartMatrix dengan esp32 dev modul. ingin menampilkan scrolling teks berganti pesan ,jam dengan RTC DS3231 dan pesan teks biasa bergantian di panel P5 64x32. Tampil secara bersamaan, cuman saya merasa kebingungan . semua tidak sesuai dengan keinginan. adakah yang sudi kiranya memberikan contoh kode.
dan apakah code yang saya ambil dari contoh smartMatrix salah. terimakasih

hi, greetings greetings.
I apologize in advance because I’m really a beginner.
hopefully in this community I get new lessons and guidance. I’m trying to learn the SmartMatrix library with the esp32 dev module. want to show scrolling text alternating messages, hours with RTC DS3231 and plain text messages alternating on a P5 64x32 panel. Appear simultaneously, but I feel confused. all not as desired. can anyone please provide a code sample.
and is the code that I took from the smartMatrix example wrong. Thank You

Can you help teach me To Edit Code tags in this Forum, as I am new to the forum totally newbie. let it be a lesson for me…

Can you help me with the above code. I’m confused about displaying scrolling text simultaneously with the next message, the clock is fixed and the text usually changes messages.I took from the SmartMatrix demo example and added a little code
