PWM controlling

HI, I need some SPI_SLAVE chip, which controls 1 PWM channel through SPI interface. I dont want any microcontroller with PWM channels. All I need is not-programming chip controlled by SPI interface. Could anyone give me a advice? Thanks, Vojta

Something like a TCL5940? If you search the web you should find several breakout boards for this part. Also, there are several mbed libraries, including

Import librarytlc5940

This library creates the interface to operate the TLC5940. This device manages 16 PWM outputs.
