When playing a sound and the uart handling loop is tied to the IdleHook, not every command is received correctly. I tried it with echoing all received data back. Have you replaced the LoadCheck function? Because UART is clocked from the core clock, it can miss some data if the core clock is changed...

I read in the vlsi.fi FAQ that the vs1053 SPI CS lines must be low for the complete size of the file XCS must be low for the whole transfer, i.e. 32 bits, XDCS must be low for at least a whole byte (8 bits). Both should not be active at the same time. And make sure you only change XCS or XDCS when ...

I already tried in suspend mode to not shut down the analoge driver, but this didnt help, because the voltage on L,R and CBUF is also dropping (but not to GND). The suspend mode has its own voltage set. If you want to keep the analog voltage steady in suspend mode (low-power pause mode), set voltag...

Do you think you could set up the project in VSIDE so that it compiles, and upload the .project and .solution files along with the other v1.19 files? Unfortunately I'm too busy right now. You may be able to use the usb hifi player project as a base (if I'm not mistaken it is included as an example ...

If I use a 24.576MHz crystal (and set SM CLK RANGE bit), what will be the SPI max speed ? 3 or 6 MHz ? When you set the CLK_RANGE bit you effectively and in actuality divide the input clock by 2, so the whole chip sees only 12.288MHz clock. So, after reset you should use max 3MHz because CLKI is 12...

After I checked the incremental linking option at properties linker menu, it became ok. Incremental linking only brings object files from the link libraries to resolve any undefined symbols, but it does not actually allocate space for the sections. You will not get an executable program when you us...

You can disable the USE_WATCHDOG define to prevent a watchdog reset.

can the VS1053 be controlled by sending commands from a uC via the SPI interface, like PLAY [fileindex], RECORD, PAUSE, DELETE [fileindex]...? I have now added the 1.19 version of the vs1053 standalone player / recorder to the VS10XX prototyping board page. I did not have time to check if the Makef...

Do you know if there's some code examples available, or if there perhaps will be sometime in the future? Even if the code is at beta stage, or not fully implemented or documented, I will be excited to play with it on the VS1053 proto board It has been a while since I worked on the Standalone Player...

Have you tried removing the boot jumper AND the SD/MMC card?

If the card is inserted, GPIO1 will be high and GPIO0 low, and that combination starts the Real-Time MIDI mode. This mode receives MIDI commands from UART at 31250bps, thus no emulator connection.
