Hi Stewart, another interesting suggestion to add to the "bag of tricks" for this project ! Thanks. 73 Alberto I2PHD ------------------------------ Stewart Nelson wrote: Hi Alberto, The filtering requirements are less onerous if the dithering frequency components are maximized, e.g. by a DDA algorithm. In Johan's example, add 442 to a variable each main PWM cycle. If the result is less than 1024, send 705 to the PWM. Otherwise, send 706 and subtract 1024 from the variable. This results in a sequence of 705, 705, 706, 705, 706, 705, etc. |
