06:37 <zmatt> Siegurd: setting ADC_CLKDIV to zero is forbidden

06:37 <zmatt> iirc it should be set to produce a 3 MHz clock, I'd need to check the clkdiv value for that

06:47 <Siegurd> This is my code that gives me ~140kHz ADC reading frequency. https://pastebin.com/9ha9CiWf

07:00 <Siegurd> When I change the ADC_CLKDIV value from 0 to 1, the ADC reading frequency is divided by 2 and becomes 70kHz. So I thought this was a working solution

07:55 <zmatt> see the comments in adc.dtsi regarding how the configuration affects the sample rate

08:09 <zmatt> Siegurd: minimum value permitted for clkdiv is 7

08:09 <zmatt> (resulting in 24 MHz / ( 7 + 1 ) = 3 MHz adc clock)

08:14 <Siegurd> Yep. Setting ADC_CLKDIV to 7 gives 200KHz F

08:20 <Siegurd> Should I use ADC_TSC.STEPENABLE_bit.STEP1 = 1 in a while loop for ADC channel 5 continious reading or before?

10:41 <zmatt> uhh normally you don't need to touch STEPENABLE after initialization

12:57 <Siegurd> Can I create array: uint16_t ADC[20000]; in PRU to send it to ARM via RPMsg?

13:01 <Siegurd> Or should I use Shared Memory to PRU interact with ARM?

14:57 <dinuxbg> Siegurd: RPMsg has something like 512 byte limit per transaction. Either you need to send your array in chunks, or use shared memory.

15:15 <Siegurd> @dinuxbg Are there any exapmles how to write and read shared memory data from PRU and userspace?

15:17 <Siegurd> I found this example https://markayoder.github.io/PRUCookbook/05blocks/blocks.html but there is only PRU side of shared memory

17:14 <Siegurd> can pru_rpmsg_send() be used without pru_rpmsg_receive()?
