Part Number:TMS320F28069
Hello
Our application uses a 28069 to control a printhead @12Mhz using SPI. Works great, but now we need 7 SPIs @12MHz. There just isn't time to send out all the data using a single SPI, just wondering if this might be possible using the CLA. Perhaps setting up a pwm at 12MHz to trigger the CLA, which would modify PWM signals every cycle to emulate SPI? The CLA and the main CPU really do run in parallel, correct?
This would be easy peasy with an FPGA, but the 28069 is just so nice for everything else we're doing, so we want to give it a shot.
Any ideas?
