# Prepare
|
|
Before everything
|
|
We assume that you have a Devterm with stock os running
|
|
and a little bit of Linux compiling experience
|
|
know how to install packages by package manager like apt
|
|
|
|
## WiringPi
|
|
### CM3 or CM4
|
|
```
|
|
sudo apt install -y wiringpi libwiringpi-dev libcups2-dev
|
|
```
|
|
|
|
### A06 A04
|
|
```
|
|
git clone https://github.com/clockworkpi/DevTerm.git
|
|
cd DevTerm/Code/devterm_wiringpi_cpi/
|
|
sudo ./build
|
|
#chose 0 or 1 depend which board you have
|
|
```
|
|
|
|
### R01
|
|
```
|
|
git clone https://github.com/clockworkpi/DevTerm.git
|
|
wget https://github.com/WiringPi/WiringPi/archive/refs/tags/final_official_2.50.tar.gz
|
|
tar zxvf final_official_2.50.tar.gz
|
|
cd WiringPi-final_official_2.50/
|
|
cp ../DevTerm/Code/patch/d1/wiringCP0329.patch .
|
|
git apply wiringCP0329.patch
|
|
sudo ./build
|
|
#Choice: 2
|
|
```
|
|
|
|
# Compile thermal printer driver code
|
|
```
|
|
git clone https://github.com/clockworkpi/DevTerm.git
|
|
cd DevTerm/Code/thermal_printer
|
|
make
|
|
sudo systemctl stop devterm-printer
|
|
sudo cp -rf devterm_thermal_printer.elf /usr/local/bin
|
|
sudo systemctl start devterm-printer
|
|
```
|
|
## Debug or run it from manually
|
|
1. setup socat socket for data receving for thermal printer
|
|
```
|
|
sudo systemctl stop devterm-printer #stop service
|
|
sudo systemctl stop devterm-socat #stop service
|
|
sudo socat -d -d pty,link=/tmp/DEVTERM_PRINTER_OUT,raw,echo=0 pty,link=/tmp/DEVTERM_PRINTER_IN,raw,echo=0
|
|
sudo ./usr/local/bin/devterm_socat.sh # <- this .sh file is in DevTerm/Code/thermal_printer/usr/local/bin/
|
|
```
|
|
1. run devterm_thermal_printer.elf
|
|
```
|
|
sudo ./devterm_thermal_printer.elf
|
|
```
|
|
|
|
now you can test the printer by cat or echo something into `/tmp/DEVTERM_PRINTER_IN`
|
|
eg: `echo "hello world\n\n\n\n\n\n\n\n\n\n" > /tmp/DEVTERM_PRINTER_IN
|
|
|
|
we recommend use [tmux](https://github.com/tmux/tmux/wiki) to do this job
|
|
so that you can run and see all the commands output in a single terminal window
|
|
|
|
## For CUPS
|
|
just install `devterm-thermal-printer-cups`
|
|
``` sudo apt install devterm-thermal-printer-cups```
|
|
|
|
this package will add a CUPS serial printer adapter,a CUPS filter for the DevTerm's thermal printer
|
|
and will let other programs to print content through image printing using DevTerm's thermal printer
|
|
source code is in https://github.com/clockworkpi/DevTerm/tree/main/Code/devterm_thermal_printer_cups
