| /**** BootLoader for PIC16F887 |
| Ussage: |
| ascii-xfr -s -v -l 110 ./bltest.hex > /dev/ttyUSB0 |
| ascii-xfr is part of 'minicom' package |
| Add "uf\n\r" to the first line of .HEX. or use this script: |
| echo uf > /dev/ttyUSB$1 |
| ascii-xfr -s -v -l 100 ./bltest.hex > /dev/ttyUSB$1 |
| Or add "uf\n\r" and add some dummy characters at the end or begin of each line (for 100 ms delay) and use: |
| cp ./bltest.hex > /dev/ttyUSB0 |
| For adding characters you can use this: |
| sed -i 's/^/pppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppp/' ./bltest.hex |
| sed -i 1i"uf" ./bltest.hex |
| Windows script: |
| mode com1 baud=9600 parity=n data=8 stop=1 rts=off dtr=off xon=off |
| echo uf > com1 |
| ping 1.1.1.1 -n 1 -w 100 > nul |
| FOR /F "tokens=1*" %%i in (bltest.hex) do @echo %%i > com1 & ping 1.1.1.1 -n 1 -w 100 > nul |
