Hello all,
I have a spare Yamaha keyboard assembly part #WH757100. This keyboard is used on Yamaha CVP-409 and CVP-509 digital piano. I need to convert this keyboard to a MIDI controller.
There are three microcontroller chips on this keyboard: PD780031AYGK-N06 (X2599200) E-TKS.
The output connector of this keyboard has two signal pins: SDA0 and SCL0 which are come out from pin 13 & 14 of the micro controllers PD780031AYGK-N06. I need to know the output of this keyboard which is compatible with a UART so that I can use the Teensy to make it works.
I need more information of the controller chip PD780031AYGK-N06. I cannot locate the datasheet of this chip. Does anyone have it? I need to know the description of the pins: 13 & 14 of this chip.
Please help.
Thank you,
Peter
