Renesas RX231, RX26T, RX62N, RX631, RX64M, RX65N, RX71M, RX66T, RX72T, RX72N pseudo PSG music performance sample
This is a sample of a pseudo PSG music performance using an RX microcontroller.
- On the RX72N, digital data is output from the SSIE.
- Normally, analog data is output from DA0/DA1.
- It was originally designed for the R8C, but the RX microcontroller's built-in D/A output produces a very high quality sound.
- The pseudo-PSG class is mainly implemented to play music using square waves (similar to NES).
- Sampling is done at 48KHz.

- Connect the indicator LED to the specified port.
- Connect the amplifier to DA0/DA1.
- In the RX72N Envision Kit, the output is provided through the analog output pins.
- In the DA0/DA1 analog output, the silence level is the middle potential of the supply voltage, so voltage conversion must be performed when connecting to a line amplifier.
- The reference circuit for analog to line output is AUDIO_sample, so please refer to it.
- It is not necessary to get it.
- The score for the piano version of Dragon Quest 1, Radatome Castle has been entered. （You can also create your own score.)
- You can also create your own score.
- Move to each platform directory and make it.
- Write the psg_sample.mot file to the microcontroller.
- The LED flashes every 0.25 seconds.
- Music starts playing, analog output from DA0/DA1. (mono)
- For RX72N, SSIE output.
