Thomas,

there may be a bug in the max7317 component:
uint8_t max7317::Input(uint8_t port)

  uint8_t* p = m_spibus->spi_cmd(m_spi, buf, 1, 1, port + 0x80);
According to the max7317 specsheet the read operation needs a second (dummy) byte. So this should be…
  uint8_t* p = m_spibus->spi_cmd(m_spi, buf, 1, 2, port + 0x80, 0);
Please try & report.

Regards,
Michael

Hello,

How can I read inputs from max7317.
when I try to log ESP_LOGD(TAG,"EGPIO5 input: %d", MyPeripherals->m_max7317->Input(MAX7317_EGPIO_5));

i get allways 0 when i put the egpio pin to GND or 3.3v
do i somthing wrong or does it not work.

Regards Thomas
