52833 QFN40 test carrier

[wzszzxj]

hi，

   we  are using52833 QFN40 to test carrier,but the  program will loop at as the picture bellow,while it runs well in 52833 QQFN73 in another board, why? Coutl you help me?

 Now,By debugging,It seem to be cause by use High voltage,But how to config to use high voltage?how to configure REG0 & REG1？

Hi,

Now,By debugging,It seem to be cause by use High voltage,But how to config to use high voltage?how to configure REG0 & REG1

Why do you think this is caused by high voltage? Can you elaborate on your observations?

REG0 can be configured by writing to the REGOUT0 register.

hi，Jard:

    Now,I found when REGOUT0 & REGOUT1 congfiured as LDO(High voltage Mode), it   is no problem to test carrier unmodulated,but hard to test carrier modulated,and it loop as the picture below:

Hi.

Could you try setting up a modulated carrier with the Radio Test example from our SDK and see if you get the same issue?

hi,jared:

     In a mouse design,but in the normal votage mode, it can generate carrier modulated correctly.Now in this dongle design,it can't  generate  carrier modulated ,but in high voltage mode.In this configuration,it can generate carrier unmodulated.

Hi,

Could you try using the example I linked in my previous reply and see if you're able to setup a modulated carrier? I'm not sure if the issue is due to your custom board or your firmware. If you're able to setup a modulated carrier with our example then we can assume that your HW is ok and that the culprit is your firmware.
