And for debugging purposes, is it a good idea
You are correct to mention this TJF. In production, I won't bother to do
convert it to a human-readable number. It helps with debugging right now
though.

Thanks Robert! I issued a pull request with a couple minor changes to add a
variable where you explained:

Here's the text of the pull request that describes how it could be used to
make a smaller image size than the size of your microSD card

Yes. That is what pin1 of P1 is for. It is exactly the same as the DC c
Clock cycle's good subject. Seems some thinks everything PRU does is one clock
cycle ( 5ns) perhaps assembler instructions are. Also confusion about actual
speed of control loops.A 100ns control loop runs every 100ns and does input,
decisions and output that fast. Lastly the PRU has small codes

I think I can read in about 3 pcs. LT2500-32 via the PRU in Software.
The LT2500 ADC delivers 32 bit results via SPI, and with the capture and
conversion time slots it needs 100 MHz SPI to process each 1MHz sample.
The ADC feeds its data to a shift register in a Xilinx 2c64 Coolrunner.
The PRU
Thank you very much for your reply.
But if I connect it to pin1 of P1, can I connect it directly to a 5V power
supply without using usb?

Hello there,
I will use pocketbeagle for the first time, but I do not know how to power
the pocketbeagle. I have to feed it from the computer. How can I feed
something like a battery directly? Is it possible to connect the pins
directly to the battery? When I look at other projects, it has been

I got it working, and I hope to never revisit it. It was kind of a surprise.
I selected a 1MS/s 16-bit SPI ADC and assumed a 16 Mhz SPI clock to get the
data out. I totally missed that the ADC can’t sample, convert, and send at the
same time, so I basically have 300nS to get my 16 bit out. E
How about changing the partition size in the make flasher script? Could there
be an option to make it the same size as the eMMC? Where is the partition size
determined?

I would be stunned if the GPIOs don't have synchronizer flip-flops as they
are sampling a signal asynchronous to the 200MHz clock. That would account
for 2 clocks. You probably need one extra to clock data into R31. And
then one clock to read R31.
50MHz is a pretty smoking speed for SPI--you
For all who want to learn:
Walter is formating a human readable number in the PRUSS code (function
ltoa).
How much PRU cycles does a four digit number need? And how much are
necessary for a one digit number?
Note: The PRUSS are fine for realtime solutions (if your code allows that).
