pcw2hid: Fixup programming instructions
Use a very slow SCK clock for loading up the fuses
Use a somewhat slow clock for loading up the bootloader
This allows to get both of them loaded reliably.

| 1 | Amstrad PCW keyboard to HID adapter
|
|---|
| 2 | ===================================
|
|---|
| 3 |
|
|---|
| 4 | This adapter allows to connect the keyboard from the Amstrad PCW to a modern computer using USB.
|
|---|
| 5 |
|
|---|
| 6 | It is powered by an AT90USB AVR microcontroller, because these implement USB in
|
|---|
| 7 | hardware and make it easy to implement an HID device.
|
|---|
| 8 |
|
|---|
| 9 | You need the LUFA USB stack to compile this project. I am not including it to
|
|---|
| 10 | avoid code duplication. Download and extract it yourself, or set the LUFA_PATH variable
|
|---|
| 11 | to where you already have it when compiling.

|

| 19 | ======================
|

| 20 |
|
|---|
| 21 | Connect the board to the STK500 programmer ISP6 connector, make sure the clock is running, if not,
|
|---|
| 22 | connect the crystal from the STK500 to the board crystal outermost pin.
|
|---|
| 23 |
|
|---|
| 24 | pushd code ; make fuse ; popd
|
|---|
| 25 | pushd bootloader ; make avrdude ; popd
|
|---|
| 26 |
|
|---|
| 27 | Then connect the board by USB. It should be in DFU mode
|
|---|
| 28 |
|
|---|
| 29 | pushd code ; make flash ; popd
|
|---|
| 30 |
|
|---|
| 31 | Disconnect and reconnect the board, it should still be in DFU mode
|
|---|
| 32 |
|
|---|
| 33 | Finally connect the keyboard to the board and reconnect it, this time it should show up as keyboard.
