Communication with SPI Daisy Chain
2003-09-15 02:49 AM
Could ST7-series MCU allow for daisy chainning of multiple MCU on
a single SPI bus? I connect ST72264 with ST72324. The MOSI pins are connected together as are MISO pins. The slave ST72264 can get correct data byte from master ST72324, and output right data on MISO pin(measured in scope). But ST72324 always gets data byte 0xFF in SPIDR register. Who could tell me how to solve this problem? Thanks a lot.mailto:david@cyberpowersystems.com.tw
