Hi I have a problem. I did design a hardware of 36 x 36 mm with the DSP56F8323 and your performance is very good, this debuging and programing. The modules PWM, GPIO and SPI is corect, but the voltage VLO, VMID and VHIGH of the DSP is the same. Then the ADC don't function correctly. The size is very importance, then I don't can do my design more big. I hope answer. Thanks.

Hello, all. My goal is to use 56F8323 Motorola's Hybrid Controller for filtering a sinusoidal signal sampled up to 96 KHz with a bandpass. To implement the digital filter I've to multiply 4 float values and (add/subtract) the results, between every sample. At this moment I use the uController to get the signal from the integratedADc and reproduce the sample through a SPI DAc, all at ...

Our product is medium voltage (4160V) variable frequency drive. It consists of 9~24 power cells depending on the power level of the load. Each power cell has a control board with a DSP56F807 and an Altera EPLD on it. The DSP talks to the EPLD via SPI port and the EPLD talks to a master control board via a fiber optic cable. The drives that we have DSP watch-dogged is used in a coal po...
