DAC for DSP TMS 320 F240
This is an Analog to Digital Convereter (DAC) 12 bits 4 DAC linked with just three wires
via a SPI serial interface of the TMS 320 F240.
I have adapted it to an IMMC 240 kit from Technosoft
but it is suitable for any F240 board.

NEW : LCD screen for DSP TMS 320 F240
This is how to connect an LCD "2x16 chars" screen to a F24X DSP device thanks to a serial interface : SPI. The DAC and LCD screen are connected to the same SPI and are addressed successively. The TMS 320 F240 is mounted on an IMMC 240 kit from Technosoft
but it is suitable for any F240 board.
