| Jun 28, 2016 at 19:33 | comment | added | joan | You have a duff DSO. My £5 Salae clone can see 5, 6, 8, 12 MHz clocks. It only samples at 24 MHz so that's as far as I went. This was a Pi2. | |

| Jun 28, 2016 at 19:00 | comment | added | joan | Not that I am aware of. The same maths is used for all frequencies so I doubt it would suddenly go wrong at 5 MHz. What command are you using? | |
| Jun 28, 2016 at 18:47 | comment | added | cr0ssb0w | The library works well. Thank you. But I was only able to generate clock signals up to 5 MHz. The DSO would also verify it. But anything above 5 MHz, the DSO would not show it (shows some arbitrary data) even though the library you provided says it is capable of producing up to 30 MHz. Is there an issue with frequencies above 5Mhz? | |

| Jun 27, 2016 at 7:23 | comment | added | joan | All models but A and B means A+, B+, Pi Zero, Pi2B, Pi3B, and the Compute Module. Clock 1 is used for Ethernet timing. Don't use clock 1 unless you know what you are doing. Clock 0 and 2 are safe. You can also use the two hardware PWM channels to create a clock (see the similar HP command). | |
| Jun 27, 2016 at 6:09 | comment | added | cr0ssb0w | Thank you for your reply! But please can you mention what does it mean by 'All models but A and B.'? Will these commands still start a clock on pin 6 and 20 since others as it mentions are reserved for system use and I would not want to crash my pi? | |
