Modifying the CY3240 I2USB Firmware
I'm trying to modify the CY3240 firmware (through PSoC Designer) so that it retains all its bridge functionality but can also use some of the I/O pins on the dev board to read voltages through its internal ADC. Ideally, the dev board would function as normal, routing USB commands to the i2c bus, but would also be able to intercept certain packets that tell it to access an I/O port.
Anyone have experience with this (e.g. sample code)?
