For less than two bucks you get a 16MIPS 16-bit MCU with 64Kbytes of Flash Memory, 4KB of RAM, plenty of peripheral modules where you get to choose for most of them which one you connect to each pin, very flexible clock configurations, etc, all in a 28-pin package. Part Number: AM3358 Tool/software: Linux I have been chasing what appears to be packet corruption when using the CAN bus at reasonably high utilization. Gossamer Mailing List Archive.

Please note: if you are ordering a re-reeled item then the order cut-off time for next day delivery is 4. MCP23S08 With Arduino: I recently started to think about a project that would require more GPIO pins than my selected micro controller board has. Port expanders, as the name implies, are chips which provide a number of pins with many of the capabilities of GPIO pins, controlled over I2C or SPI. MCP23008/MCP23S08 8-Bit I/O Expander with Serial Interface Features 8-bit remote bidirectional I/O port - I/O pins default to. Ask a Question Ask a Question. Zoom out and see the bigger picture, or focus in on an unprecedented level of granular data. Abstract: mcp23017 application note mcp23017 "application note" MCP23x17 MCP23017 AN1043 MCP23S17 MCP23008 MCP23017-I2C MCP23S08 Text: MCP23S17: SPI Interface The functions and features of the MCP23X08 and MCP23X17 are basically the same , The "S" devices (MCP23S08 and MCP23S17) have SPI interfaces. Raspberry Pi Model A WiFi connection using EDPU EP-MS150NW tested OK MCP23s08 learning notes; Now I have skimmed through the 4 or 5 application notes to get a. The MCP23s08 and MCP23s17's have 3 address select bits so in-theory you can connect up to 8 MCP23s08 and MCP23S17's on the same SPI select signal giving you a GPIO capability of an additional 128 pins per SPI select signal when using these devices.
