Hello,
I’m new to midibox, but I’ll have a lpc17 core soon. I want to to build a hardware midi player like in tutorial #019 on ucapps.de
I have a teac ca200 multi card reader ( sd mmc rs sm cf md etc) from an old dell pc. It has a 2x5 pin connector to the pc motherboard, but should be USB. The cable has red white green and for black wires.
Can I connect this device to the core and use it as a storage device? Does anyone have experience With this?
Thanks for your hints & ideas!
No, you would need a USB host with proper drivers to use this device. LPC17 under MIOS does not act as USB host - you can see that already from the connector that is used.
In order to use the SD slot part of your device, you would have to destroy it - cut the traces on the PCB that run to the SD card connector/slot and solder your own connection/cable there. Honestly, I would not do that though, the risk of not getting a proper solder joint when connecting to PCB traces is too high.
Can recommend these el-cheapo SD-Readers, they are easy to obtain and cheaper than most stand-alone SD-Slots. Just open the plastic case, desolder all components from the PCB and solder the SD cable pins directly to the SD-card-holder pins as described in the SD-Card tutorial on ucapps.de.
You can re-attach the plastic case afterwards, so you will get a nice external/internal sd reader for very cheap.
Bye,
Peter
Great find!
