multichanneli2c failures

I'm getting sporadic I2C failures using multichanneli2c. Not always an error message, sometimes it's just invalid content in the ADC I'm reading. However I do get some error messages now and again. They appear to be triggered by Ethernet usage as the failure rate shoots up whenever I see network ...

sim1.mcpwm.sm[submod].val[0] = reset/2; //Median 0

The MCF54415 reference manual is not terribly clear regarding this register. However, commenting out this ...

Dual DAC problem

My app has been successfully using DAC0 as well as PWM_A3 and PWM_B3 as independent channels. The DAC as well as the two PWMs are each configured for trivial use, i.e. I simply write new pulse widths or a DAC value as needed. Attempting to add DAC1 causes PWM_B3 to reload erratically. Obviously I'm ...
