folly Posted May 3, 2015 Report Posted May 3, 2015 (edited) hi! STM32F4 DISCOVERY with it and solved the problem of jitter (potentiometers)? best regards. Edited May 3, 2015 by folly
TK. Posted May 3, 2015 Report Posted May 3, 2015 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.
folly Posted May 3, 2015 Author Report Posted May 3, 2015 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.
TK. Posted May 3, 2015 Report Posted May 3, 2015 The MBHP_CORE_STM32F4 has more robust analog inputs, 7bit resolution is possible without jittering values. Best Regards, Thorsten.
FantomXR Posted May 3, 2015 Report Posted May 3, 2015 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 ;)
folly Posted May 3, 2015 Author Report Posted May 3, 2015 I need to 4 potentiometers for volume track.
folly Posted May 4, 2015 Author Report Posted May 4, 2015 (edited) hi! I found eror while drawing the pcb. Edited May 4, 2015 by folly
folly Posted May 4, 2015 Author Report Posted May 4, 2015 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.
