|
||||
|
||||
If you load that code at `0xa000` and call it, it will print "Hello World!" by
|
||||
using the `printstr` routine from `core.asm`.
|
||||
|
||||
## Doing the same with the BASIC shell
|
||||
|
||||
The BASIC shell also has the capacity to load code from serial console but its
|
||||
semantic is a bit different from the regular shell. Instead of peeking and
|
||||
poking, you use `getc` to send data and then `putc` to send the same data back
|
||||
for verification. Then, you can use `poke` to commit it to memory.
|
||||
|
||||
There's an upload tool that use these commands and it's `uploadb.py`. It is
|
||||
invoked with the same arguments as `upload.py`.
|
||||
|
||||
Once your code is uploaded, you will call it with BASIC's `usr` command. See
|
||||
BASIC's README for more details.
