Re: [beagleboard] Re: Periodic delay reading analog inputs with C, will PRUs solve it and is it worth it?

To complete on TJF answer, you can find the address defined by CM_WKUP_ADC_TSC_CLKCTRL in *hw_cm_wkup.h *line 101value (0xbc) and in *soc_AM335x.h * line 139. Le mardi 13 avril 2021 à 05:16:58 UTC-4, TJF a écrit : > I'm not a C guy (but prefering FreeBASIC for ligh-level and ASM for PRU >

Re: [beagleboard] Re: Periodic delay reading analog inputs with C, will PRUs solve it and is it worth it?

HWREG: is a macro that lets you write directly to the register of the bone; I think it is defined in the hw_type.h header. From a quick look, I would say that is the base address of the TSC ADC on the chip and TSC_ADC_SS_IRQSTATUS is the register's address. SOC_ADC_TSC_0_REGS is defined i

Hi, I believe there are some simple ADC-read example directly in the image under /var/lib/cloud9/Techlab/.challenges, or here: https://github.com/beagleboard/cloud9-examples/blob/master/PocketBeagle/TechLab/.challenges/analogIn.pru0.c They are labeled for PocketBeagle but it's the same ti-am335

Hi! >From my experience on the PRU, using Remoteproc is the most recent way to do things and UIO is an older technics. I believe there is some rpmsg examples under /var/lib/cloud9/ in the BB images. However, depending on your application you can have a look at Libpruio which does most of the

Hi Roland, I am not sure that I completely understand your question but have you looked at the iio_generic_buffer (https://github.com/torvalds/linux/blob/master/tools/iio/iio_generic_buffer.c)? I did something similar 3 years ago and used this example to sample the BBB ADC using the iio drive

[beagleboard] BBAI PRU-I2C driver

Hi All, I am trying to develop a PRU driver for I2C on the Beaglebone AI (Ti-am5729). I have some questions about the setup procedure using Interrupt and polling (I am not using DMA). I am not quite sure about the differences between the setup described between section *24.1.5.1.1.1.1 and 24

[beagleboard] Re: Best way to get elapsed milliseconds

Depending on how precise you need to be, I would go for the PRU-ICSS. They can control the GPIOs pretty easily. Le mardi 16 février 2021 à 10:03:47 UTC-5, wal...@edenconceptsllc.com a écrit : > I have a BBB Wireless running Linux beaglebone 4.14.108-ti-r106 #1 SMP > PREEMPT Fri May 24 22:12:3

[beagleboard] Disabling I2C1 on BBAI

Hi everyone, I am trying to disable I2C1 (connected to the on board STMPE811 ADC) so that Linux is not recognizing it. My end goal is to use the PRU-ICSS to read from the ADC using the I2C bus. I have been playing around with the following devices trees: am5729-beagleboneai.dts

Hi Denis, Thanks for the help and sorry that I only answer now. I understand what you mean with the I2C, I tried to change the topic of the post without luck yet. I am starting to work on that with the examples you have provided. Do you think that the PRUDAQ project (here
