Hey TFJ, Thank you for answering my question. Calling pruio_config() twice was my bad. I didn't notice. I already removed it as the printf() function. Anyway it gives the same result around 10kHz.
Pardon my ignorance but about the ADC, how can I activate less steps? And how can I remove the default configuration (open delay 0x98, avaraging 4)? It is in the library "pruio_c_wrapper.h"? If so for what value should I change (#define PRUIO_DEF_AVRAGE 4)? The thing about libpruio 0.2, is that I've already installed yesterday, but when I try to do the stepper example, it gives the message (setValue P1 error (no pin control)), and I don't know yet what the problem might be, and I need to use the GPIO to do the same algorithm above. So I was still trying something on libpruio0.0.2. Maybe you can help me figure it out, if possible. I thank you again, Luciano.
