Mimpi kecilFungsi LogStatus dapat diekspor secara real-time ke status bar.
wbe3- Potret kecil/upload/asset/2e81ec8a38c0f65e9f380.jpg Saya menambahkan ke bagian bawah lingkaran utama, dan kemudian muncul terus menerus mencetak, jika saya menambahkan waktu cetak, logika lingkaran utama tidak berjalan, perintah menerima tidak merespons, bagaimana untuk memecahkannya, putih kecil, tolong tunjukkan kepada saya
Mimpi kecilFungsi log dapat mengekspor log, yang dapat diekspor di tempat yang sesuai dengan program.
Mimpi kecilOKX interface, yang dapat beralih ke lingkungan pengujian cakram analog OKX, menggunakan exchange.IO (("simulate", true), yang dapat beralih ke lingkungan cakram analog.
