@mauriciobridge Can you help with translations changes on the source page?

Are these usable?
Signal detected = "Sinal detectado"
No signal = "Sem sinal"
Analog input requires Expansion Module = "Entrada analógica requer módulo de expansão"

And can you offer a valid replacement for "ã" ?

Hi @pitts-mo!
Just wanted to clarify - those translations are in Portuguese. Here are the Spanish versions:

• Signal detected = "Señal detectada"
• No signal = "Sin señal"
• Analog input requires Expansion Module = "Entrada análoga requiere Módulo de Expansión"

And no need to replace "ã" since we're using Spanish, and current fonts already have all the Spanish characters we need for Spanish (like ñ, á, é, í, ó, ú).

Let me know if you need any other Spanish translations!
Thanks!

Sorry @mauriciobridge ,

Thank you for correcting me.
