Part Number: TIDA-01555 Other Parts Discussed in Thread: TIDA-010249 Tool/software: For quick proof of concept, we have TIDA-010249 with us. Is it possible to test below configuration?
Thanks and best regards,

Part Number: TIDA-01555 Other Parts Discussed in Thread: ADS127L11 , Tool/software: We want to interface 20 nos. of ADS12L11 ADCs to PRU of Sitara processor.
We want to achieve sampling rate of 100 ksps with above architecture with parallel sampling.…
Hello,
Questions about your usecase
Are there specific requirements for these ADC samples? e.g., do samples from one ADC need to be captured within a specific time relative to samples from another ADC?
I often see ADCs that are capable of sampling up to…
Hello Daisuke-san,
There are a couple of different directions we could take this discussion.
Help me understand what you are trying to do
If you were modifying the linker.cmd file, SECTIONS entry like at https://git.ti.com/cgit/pru-software-support-package…
We do have some examples on other processors showing how the PRU subsystem can be used to interface with an external ADC.
AM335x (similar PRU subsystem to AM62x, just an older version): https://www.ti.com/tool/TIDA-01555 https://git.ti.com/cgit/apps/tida01555…
Part Number: TIDA-01555 Hello,
I'm interested in TIDA-01555. One of the BOM lists does not show the part number partially. -> TIDA-01555E1(001)_Data_acquisition_TI-BOM.pdf
Could you give me the appropriate file(PDF or EXCEL)?

Hello António,
Basic overview: for INTC theory the PRU Interrupt controller (INTC) has 3 parts: Host interrupts, interrupt channels, and system events (or interrupt sources). Please refer to the Technical Reference Manual (TRM) section "PRUSS Local…
Hello Tom,
Question
How much memory is the PRU writing when it is taking 1-2us per write?
Design ideas
If your code is written on a single PRU core, and looks like this:
sample ADC
sample ADC
...
sample ADC
write ADC data to DDR
sample ADC
sample…
Hey Dominic, thanks for looping me in.
Hello António,
Questions
1) What version of Linux kernel are you using?
2) Will you grant userspace root level access in your final product? My assumption is that most applications do NOT want to give userspace…
Hello John,
SPI debug
I am going to be limited in the support I can offer from a SPI configuration side.
Are you able to dump the SPI registers immediately after configuration by the MCU+ SDK, and compare them against the SPI register values when you…
