Details:

ISSUE:

avrdude -c arduino-ft232r -p atmega88p -e

avrdude: AVR device initialized and ready to accept instructions
avrdude: Device signature = 0x1e930f
avrdude: erasing chip
avrdude: Device is not responding to program enable. Check connection. 


FIXES in patch:

  - main issue: after some instruction (presumably chip erase) the SCK is H,
so in that case, the consequent enter programming mode was of no success

  - the timing does not reflect the datasheet of the cpu (20ms!) 

Daniel.
