I just got around to opening and testing the MP3 Trigger board that I had purchased years ago. I believe this is the WIG-11029 version based on the fact it uses the older style headphone jack but has the VS1063 CODEC. There doesn’t seem to be a model number on the PCB. I just loaded a few MP3 files on this board, 13 to be exact and all tracks sound choppy when played. I’ve tried 3 different Micro SD cards, a Scandisk 2G SD, Kingston 4G SDHC and even a Scandisk 64G SDXC card. All produce the same results. All of these cards sound just fine on the computer. Is my board defective or is there an adjustment to make? This came right out of the sealed anti-stactic bag.
IT could be a few things - ensure you are using a regulated 5v power supply, and see what the light are doing when you power it on (refer here https://learn.sparkfun.com/tutorials/mp … 1615791300)
You may need to update the bootloader http://robertsonics.com/mp3-trigger-downloads/ or try the other troubleshooting steps suggested here http://robertsonics.com/mp3-trigger-support/ as well
I am actually using a D-Link 5V regulated power supply. Voltage is reading 5.2v. When power is applied the Red power LED illuminated with a short blip of the Green LED, then 3 short blinks of the Green LED. Everything else appears to function normally including the triggers. The tracks do play but distorted. I am not using an Init File.
Also I’ve noticed the audio always sounds clean on the first track for about 2 seconds and then gets choppy. All other tracks are choppy from the start.
I updated the bootloader by renaming and copying the new file, version 2.54, onto the SD card. Holding the center button while powering I see the rapidly blinking green light and then after a few seconds goes solid. I cycled power to try this new version but to no avail. I still have the same choppy sound.
Not sure what else I can try. I’m assuming this unit is defective. A bit disconcerning as it was fresh out of the sealed bag. None of the links to test files seem to work on that troubleshooting page.
I’ve also tried a bench power supply to no avail. Anything else to try? Perhaps a bad cap cause timing issues? If not I guess this thing is garbarge staight out of the box and wont be buying another.
Tossed in the trash. I guess I’m off to Adafruit for my solution because I’m not spending more money on another one of these with questionable design. The VS1063 is not properly bypassed. One 0.1uf cap on one voltage rail is not the same as multiple 100nf caps spread around the chip as indicated in the datasheet. There should be at least 10 By-pass caps the on the 3 power rails. RCAP, internal reference filter, wants to see 1uf. not 0.1uf on this pin. Unused UART RX pin should be tied to IOVDD, it is left open. And this is just a quick review of the codec. I’m not saying these are the cause of my issue but certainly could contribute to a marginal design.
