W5100s SPI not working

Question

Hello, im having a problem with the SPI communication with the W5100s, i send valid data to the module, but it’s not responding, i checked the CS, and the SPI config, and it’s seems to be correct, im using SPI at mode 0, with a clock of 1MHz. The MCU im using is the PIC18F46k22. CS and Clock CS1389×752 8.85 KB MISO MISO1391×750 8.81 KB MOSI MOSI1393×750 8.79 KB

Hello, It was confirmed that STM32 F103rb operated in SPI2 Mode. I think it’s an SPI Mode problem, can you try the settings again? And try setting the clock setting to 15Mhz? image757×443 86.4 KB Thank you.
