Title: [gelöst/solved] UI Board test
Post by: pe0f on 08. February 2018, 21:28:22
Helllo All,
I had a lot of joy building but testing is somewhat difficult,since i have no RF Board
How can I test the UI-board without a rf board, all I get is a white screen!
I managed to get the firmware en software loaded via DFU load
I can see the clock works I see 3.3 volt, feed via 5 V via pin 28
I can read German without any problem but typing is hard for me ;)

Hello Frans,
if you loaded the firmware successfully AND you get a white screen, you have a hardware problem.
If you indeed loaded the firmware correctly, you can try to connect to the USB, Windows or Linux should find some new devices...
Remember, you have to load firmware AND bootloader (you can load both using DFU). Without bootloader nothing but a white screen will be shown even with fully working hardware.

Hello Danilo,
Thanks for the great tip about the fact you must see new devices!
Since i did not see these the firmware process was probably not correct
So i once followed step by step the dfu bootloader procedure and with succes!
Now i have loaded firmware and everything "works" normal
I can wat to get started with the RF board ;-)
Andreas also many thanks for clever assembly of the kit was fun to build this!!!!

hello,
Just a tought would it be possible to do some testing with IQ audio
If I would take the IQ signal from my KX3 and feed this to the OVI40 Board
Can this Work ?
another question is, can i feed 8 volt to pin29 in order to test both 5 volt and 3.3 volt regulators ?
kind regards Frans PE0F |

Hello Frans,
do not address too many different topics in one thread please!
Nobody will find her again later
maybe it would be better for the exciting topic with the IQ signal from the K3 to open an own thread!
thx ;)

Yes!
pin #29 is the 8V supply for the 5V regulator (IC8) for the USB connectors
pin #28 is the 5V supply for the 3V3 regulators IC3 and IC6 |
