You could put its SPI hardware in slave mode, and use that to read the data from the scale, without needing too many interrupts (one per 8 bits).<br /><br />Also, when debugging serial I/O, I found that using a scope can be tedious, particularly for protocols like I2C. A tool like the Saleae Logic helps, since they have built-in serial decoders in the software.Jimhttps://www.blogger.com/profile/11287942263281234747noreply@blogger.com
