Hi,

 

at which resolution are you using the analog inputs?

(just copy&paste the configuration part of your .NGC file into this thread)

 

Best Regards, Thorsten.

I still use lpc1769. I bought STM32F4 and wanted to know if the problem of jiter and resolved. I would not build the PCB and then again have problems with jitter. if you tell me that and ok, I build the pcb.

The MBHP_CORE_STM32F4 has more robust analog inputs, 7bit resolution is possible without jittering values.

I'm already eroding the pcb.

 

thank you !

Hi TK,

 

do I get it right that it's not necessary to add an AINSER - module if the resolution of 7bit is enough for the user? So I guess it's the same with expression-pedals or footswitches, right?

 

Would be great ;)

hi all!

I built MBP CORE STM32F4. everything works except Aiser 64 and 8. We are sure that, S1 of J19 connects to pin PB4 of MBHP_CORE_STM32F4?

 

thank.
