Part Number: CC2640R2F Hi,
I've exact the same need for a BLE Project where I use SDK version 4.10 for CC2640r2 chip.
Thanks to all of you, I'm able to make the dynamic configuration work for my project.
However, I do make a modification in the…
Part Number: CC2640R2F I am having a hard time using OSC_AdjustXoscHfCapArray to vary the the crystal trim. I can do it just fine using SET_CCFG_MODE_CONF_XOSC_CAPARRAY_DELTA at build time but I would like to be able to adjust it at run time to tune away…
Sorry for missing something due to my negligence, the link mentions that the CC2340 calls CKMDSetTargetCapTrim and CKMDSetInitialCapTrim during power-up initialization, does this serve the same purpose as the OSC_AdjustXoscHfCapArray() function?
Hi Petar,
It is possible to achieve what you are looking for, this functionality is accomplished through OSC_AdjustXoscHfCapArray . You can store the target values for each device in a flash memory location during programming that is then used during…
Part Number: CC1352P Other Parts Discussed in Thread: SYSCONFIG , , Dear Sir/Madam, hi.
I've noticed that the sysconfig tool has no effect on the cap-array on/off and the value of cap-array to our application, even though all other sysconfig values…
Hi,
We recommend to do the crystal trimming through CCFG. You could measure the frequency offset across devices and save the average/median in CCFG. Alternatively, you could measure the frequency offset of individual devices during production and store…
TheGhostOf It turned out that CapArray was not turned off as you mentioned and it was set to its default value. It seems that even if you leave the CapArray function on Smart RFStudio unchecked, it applies the default CapArray value -43 when you set the…
Hi Ambroise,
Thanks for your inquiry. Please check the thread below, which contains a discussion to tune the capacitors together with several API references.

Hi Mehul,
Your code appears to be acceptable given the constraints around OSC_AdjustXoscHfCapArray. Please note from Section 6.4 of SWRA640 that the expected value is between -40 and 23 for the CC13X2/CC26X2. There are other E2E threads which can be…
