I scavenged a CRT TV motherboard, and there is one component that looks interesting.
This is not totally worthless (around 3€ ),
From the datasheet:
The CXP86213/86217, CXP86325/86333, CXP86441/ 86449/86461 are the CMOS 8-bit single chip micro- computer integrating on a single chip an A/D converter, serial interface, timer/counter, time-base timer, on-screen display function, I2C bus interface, PWM output, remote control reception circuit, HSYNC counter,
watchdog timer, 32kHz timer/counter besides the basic configurations of 8-bit CPU, ROM, RAM, I/O ports.
I am wondering if this kind of component is too specific to the particular task for which it was chosen in the first place. I see this mc can output PWM, so I could use this in one project where I need to drive a fan..
Now the question is, where do I start to program this component ? Is it even possible to upload another program in it ? Is so, how hard is it to interface with an
Arduino ? I came to Arduino from a developer's background (if you happen to find this question very.. naive)
Thanks !
