The MAX7300 is a general-purpose I/O (GPIO) port expander that is similar to the MAX6956, except that it does not have the constant-current LED-drive capability. The MAX7301 is a GPIO port expander similar to the MAX7300, but it has an SPI- instead of an I²C-compatible interface.

If the chip does not have a driver yet, you then will have to write a GPIO driver for the chip. One good example to start with is the GPIO driver for the MAX 7300, that is connected via I2C as well. Have a look at gpio-max7300.c and gpio-max730x.c

Technically I used devices that are pin compatible with the ULN2003 since nobody seemed to have any in stock. The microprocessor is a PIC18F2420 which communicates with the DS3231 and both MAX7300 devices using I2C. Here is the back of the clock. You can clearly see the vents which allow the heat from the light bulbs to dissipate.

Oct 18, 2017 · As long as the address spaces are not the same, 4 x MAX7300 = 112 ports, and 8 x MCP23017 = 128 ports. Or just one type and add some extra gating to select banks of the I2C expanders could also be used to add more to the single I2C channel. An interesting exercise to

Unlike PCI or USB devices, I2C devices are not enumerated at the hardware level. Instead, the software must know which devices are connected on each I2C bus segment, and what address these devices are using. For this reason, the kernel code must instantiate I2C devices explicitly. There are different ways to achieve this, depending on the context and requirements.

Actually, I did not use “4-State” in my post, and I did not find it in the MAX7300 datasheet either. Maybe, a term like “4-mode input” better describes how these inputs work. MAXIM must have integrated some tricky logic to determine if such pins are tied to V+, Ground, or if the pin levels either follow the SCL or SDA level changes.

Re: f1c100s linux 5.2 USB已完美驱动,host+device完美运行

You can still buy parallel IO cards for industrial PC’s that use 8255s. We have been using them in one of our products. They are a disaster. Given some electrical noise in an industrial environment they will flip their outputs to inputs and every thing stops working.
