MCP25625 SPI MISO not answering
Hi,&I made a custom board with MCP25625, actually made 2 of them. Now Im trying to perform a very simple transaction:&1) Software reset - sending one byte2) Reading CANCTRL registerI implemented bitbanging on MCU to avoid any hardware problems of MCU itself.I can clearly see SCK and SI, but there is nothing coming out on SO.&Im attaching SCK, SI and also a waveform on OSC2.STBY is HIGH.&

I have the same problem! You resolved this issue?
Superb Member

There's no mention of controlling the "CAN_CS" signal correctly.&
My problem is that my SO line of MCP25625 had a short circuit to ground. Electronics have always reason, don't fails :)
