Customer:
We recently purchased the MP3 Shield for Arduino with the VS1053B chip. Unfortunately, the library we normally use on the Sparkfun MP3 Shield does not work, even though it uses the same VS1053B chip. Our debugging shows issues with SD card reading, specifically with SPI.
Your product pages do not include any schematic, pinout, supported library information, or technical specifications. We need documentation for this shield - specifically the pinout, supported library, and any information about pin dependencies we may not be aware of.
Original message (Croatian)
Nedavno smo od Vas kupili MP3 shield za Arduino ( Soldered: Open-Source Electronics, Boards, Sensors & Modules – Soldered Electronics ) . Nažalost, library koji smo inače koristili na Sparkfun-ovom MP3 Shieldu ne radi, iako se radi o istom VS1053B chipu (po dosadašnjem debug-u problemi sa čitanjem SD kartice, konkretno problemi sa SPI).
Nažalost, na Vašim stranicama nema nikakve sheme, pinout-a, podržanog librarya ili ikakve tehničke specifikacije. Stoga bi nam bilo potrebna nekakva dokumentacija za dotični shield? Bili bismo veoma zahvalni na bilo kakvim gore navedenim informacijama (pinout shielda, podržani library, eventualna informacija o nekim trenutno nama nepoznatim pin dependencyu).
Hvala Vam unaprijed,
