### Single pin interface
- **bool pinMode1(uint8_t pin, uint8_t mode)** pin = 0..7, mode = INPUT, OUTPUT.
0xFF is all pins are input, 0x1F are 5 inputs and 3 outputs.
- **bool pinMode1(uint8_t pin, uint8_t mode)** pin = 0..7, mode = INPUT, OUTPUT or INPUT_PULLUP.
Do NOT use 0, 1 for mode as the 3 constants are (possibly) defined differently.
Returns true if successful.
- **bool write1(uint8_t pin, uint8_t value)** pin = 0..7, value = LOW(0) HIGH (!0). Returns true if successful.
- **uint8_t read1(uint8_t pin)** pin = 0..7, returns LOW or HIGH, might set the lastError();
