(1)電阻值與寫入之 data 間之關係式
Rwa(Dn)=Rab(256*Dn)/256 + Rw Rwa: Resistance between PW0 and PA0 Dn: code to programming MCP41050 Rw: Wiper Resistance (2)如何寫入 data 至 MCP41050 MCP41050的規劃是經由標準 SPI interface, 詳細 Timing請參考datasheet, 每次寫入的data bit數為16-bit, 前面 8-bit 是 Command, 後面 8-bit是 data, 也就是式(1)所算出來的值. 有那些command及其格式請參考datasheet.
