Second, the reads were done on the output level registers, inputs are mapped to bit fields in 0x0e & 0x0f. Third, the max7317 needs a deselect between the tx and the rx. No, really, I've tried even half duplex mode, the deselect really is necessary. <br> <br> Fix is pushed. I've also added an "egpio input" shell command. <br> <br> Regards, <br> Michael <br> <br> <br><div class="ox-b543c9b284-moz-cite-prefix">Am 09.07.19 um 20:00 schrieb Michael Balzer: <br></div><blockquote type="cite">Thomas, <br> <br> there may be a bug in the max7317 component: <br><blockquote><tt>uint8_t max7317::Input(uint8_t port)</tt> <br> <tt>…</tt> <br> <tt> uint8_t* p = m_spibus->spi_cmd(m_spi, buf, 1, 1, port + 0x80);</tt> <br></blockquote>According to the max7317 specsheet the read operation needs a second (dummy) byte.
