Can anyone advise where I can find a PIC design and code for the following application? Simultaneous generation of 3 sinewaves of differing frequency and amplitude. Due to cost and parts count, one IC and lookups are preferred over filtering. The frequencies are all below 30 Hz (subaudio). Amplitudes are 3 to 5 volts. If there is no ready-made design, perhaps someone who is interested in knocking one up for a suitable fee can contact me off-list. Thanks for your reply.
