# Hardware Verify Script
|
|
|
|
This is a sketch for low-level debugging of the TommyPROM hardware. It allows the EEPROM data, address,
|
|
and control pins to be individually set so that they can be probed to catch wiring errors. The usage is
|
|
described in the [Troubleshooting documentation page](https://tomnisbet.github.io/TommyPROM/docs/troubleshooting).
|
|
|
|
This sketch should only be used for debugging if the main TommyPROM sketch does not seem to be working. To
|
|
get started with a new TommyPROM build, load the TommyPROM sketch into the hardware and try the Unlock,
|
|
Display and Zap commands to test reading and writing. For example:
|
|
|
|
```
|
|
u
|
|
d0 ff
|
|
z0
|
|
d0 ff
|
|
```
|
|
|
|
The above commands will Unlock the Software Data Protection, Display the first 256 bytes, burn a
|
|
sequence of test data into the first 32 bytes, and then Display the first 256 bytes again.
