sdrum boss rc 30 Hello I would need the pedal on the right and the self-made interface. are you willing to sell them and in case you tell me the price?
Well, I made my own. the 3 pedals on the right are the same connection as the one for the SDRUM, the one on the left talks to a self made interface running on a self programmed Microcontroller and connected to the LOOPER to the connections on it's motherboard for the PLAY and STOP buttons. (labeled PEDAL L and PEDAL R on the schematic found in the service guide of the RC-30) The microcontroller also reads the MIDI signal coming from the SDRUM, to figure out the TEMPO and START and STOP MIDI signals. so when I start or stop the SDRUM, the Microcontroller knows this from the MIDI signals and sends the correct pulse to the START or STOP pedal on the LOOPER, holding the button on the peddel board down, sends pairs of pulses to the LOOPER's stop button, to sync it's clock to the midi clock of the SDRUM. A schematic will not help you, as there is self developed hard and software in the pedal to make it work. I plan to put a complete description of this project on a website and will let you know when its done so you can see all the details
Meanwhile, thanks for the reply. I wanted to know news of the midi interface ie brand and model and where I can buy it. and the connections between the drum loop and the interface
Hmmm have you ever heard what the Xbox 360 slim sounds like when you turn it on? I want to make that same thing with my PC but I don't know what I really need to get this project done!!!
Hi, the chipcorder is the isd2360 www.nuvoton.com/resource-files/EN_ISD2360_Design_Guide_Rev1.15.pdf The programing of it is done over it's serial spi bus. You can use the nuvoton software to build the binary file. In my case, i did this and then made a usd to spi interface with a microchip microcontroller pic16f1454 using m-stach usb firmware. Then made own software that uses the spi commands described in the isd2360 datasheet to program the bin file in the chipcorder(isd2360). Hope this answers your question.
Hey Handlepken, thanks for the reply! My programming abilities are at the novice stage currently, so the whole programming of the chips seems a bit confusing to me. So I wondering if you explain how it is that you programmed the chip itself a little more in depth. I read the manual for the ISD2360, but it doesn't say how to transfer the files into the chip itself. Thanks!
Hi, sorry for the late reply. To program the chip yourself, all info is in this document. www.nuvoton.com/resource-files/EN_ISD2360_Design_Guide_Rev1.15.pdf In short, power the chip with SSB pin low. This puts it in SPI mode. I programmed a microcontroller as a usb to spi device and connects the spi pins to the spi pins on the chip. Next step is sending the correct commands over spi checking the status pins on the chip. The commands are also described in given document. Starting page 35. I used dig_write, chip_erase, pwr_up and pwr_dn. This i do with a little software that i have written which controls the flow of data to my usb to spi microcontroller and takes care of the handshaking and status of the chip. The bin file you send to the chip you best make with the tool from nuvoton. So you are sure its correct. Hope this helps. All info i needed i found in the document i mentioned. Regards Jan
@yanjiewang i used a PIC16F723 to re create the Frequentie counter and added BT functionality with a bluegiga BGTWT11A module. the PIC interfaces with the BT module to send Freq and mode info and receive commands to control the LED display. .. was a nice project
