Re: Hobby Components Protoduino (HCPROT0068)

Hi Andrew

i have programmed the device using the ISCP port, but still not managed through the FTDI cable.

the board is great for prototyping projects and will be ordering another one soon.

easy to put together, the instructions are straight forward to follow.

Re: PCF8574 I2C to 8-bit digital port expander (HCMODU0120)

I received 3 of these and tested them, there Hex Address start at 0x20 for the current devices which are PCF8574T.
if the chip is PCF8574A the start Address is 0x38
the Sketch will need to be altered accordingly.

I.E #define I2C_ADD 0x20
