SOLVED customization of Recalbox

[cri1305]

Hello,
I'm the happy owner of a brand new recalbox, after an old one which was based on RPi3 and Recalbox v4.1.

I built it up from scratch, using RecalBox 7.0.1, a RPi4 connected to a 1TB SSD through USB3, and an USB hub to get 'free' USB sockets in front face of a printed home made case.
This case is integrating a 60mm PWM Fan for the PI, as it seems that it is mandatory now for the PI4 (the old one had a fan, but not pwm, and I choose PWM kind due to the noise generated).

I connected the PWM control of the fan to a PWM GPIO of the RPi (through a buffer), and write a quick C code using Pigpio library to control it from the CPU temperature, using HW PWM feature.

However, when came the time of compiling and testing this code, I get stuck by the lack of capacity to install the needed programs (headers, gcc, pigpio....).

is it a way to install something on the recalbox ? I did not even find an apt-get or similar.

Regards

@cri1305 RB is like a firmware, there is no tool for installing or compiling. You can try this workaround :

• install Raspberry Pi OS on another SD
• install the tools you need (compiler, libs..)
• compile and test your programm
• store the exe and linked libs and copy them on the RB SD at the right place

il should work

@ian57 thank you for the reply.
I will try it, as there should be few adherence to the kernel (except for 'basic' functions as time and proc/stat). I was hoping to use pigpiod, but I suppose I can fallback to pigpio.
Hoping there will be no conflict with the current GPIO library.

@alexsunny123 Glad to hear it

May I ask: what was your issue ?
