Can you try to install makedev prior to compile : sudo apt-get install makedev
Besides this, have you succeed in compiling the entire project and run it ?
Resolution at 70cm is about 9hz as Wspr requires 1.5Hz. Need to see if Frequency PWM could work.
Never used the serial at same time of rpitx. As rpitx move some PLL the serial clock is maybe using it to derive its clock.
Rpitx and HDMI output is not yet really tested. Can you try without HDMI output (through network ssh) to see if it solves the issue.
add ldpc_helper clone and compilation , make it work from a relative path
This is right now an known issue not documented : some frequencies are not well handled as it cross two integer steps of master PLL. Normally there is a warning...
As I understand, your application need to control Tx On/Off. You can use clkgpio::disableclk(4) and clkgpio::enableclk(4) to disable/enable the signal on GIPIO4. Method to (pipe, audio level) has to be...
Nice project ! I follow install instructions.All seems OK with mmdvm and MMDVMHost. RxSample.wav is growing but there is only silence inside. On your side : can you add gpu_freq=250...
Pwm is used in patern mode...It is based on the PLL frequency (like the clock output). Instead of just output a divisor of pll frequency in CLK mode, we use...
