Pytrack and Pysense firmware release 0.0.3 ??

[livius]

@bartp said in Pytrack and Pysense firmware release 0.0.3 ??:

It fails to instantiatie the Pytrack class:

What error you got?
I did not updated already but this config work for me few days continously.
Wipy2 + 1.7.4 + pytrack_0.0.2.dfu

[bartp]

@livius I didn't get any error; program execution simply hangs.
If I commented out these lines in pytrack.py

    # init the ADC for the battery measurements
    self.poke_memory(ANSELC_ADDR, 1 << 2)
    self.poke_memory(ADCON0_ADDR, (0x06 << _ADCON0_CHS_POSN) | _ADCON0_ADON_MASK)
    self.poke_memory(ADCON1_ADDR, (0x06 << _ADCON1_ADCS_POSN))
    # enable the pull-up on RA3
    self.poke_memory(WPUA_ADDR, (1 << 3))

then program executions continues, but Pytrack accelerometer or GNSS functions returned all zero. As mentioned in my update, downgrading back to 1.7.3b1 fixes these issues, so i'm suspecting there is an issue in 1.7.5b1. I didn't downgrade the pyrack firmware (still on 0.0.3)

@bartp
I do not know if this is somehow releated
but addresses are two bytes in this situation and then are two call to mp_hal_i2c_write_byte
but this should not make any problem..

Umm I upgraded to 1.7.5b1 and 0.0.3 and Pytrack() loads for me, however LIS2HH12 fails with ValueError("Incorrect Product ID")

Anyone else?

I'll try to dig out the problem later if there are enough hours in the day...

[jmarcelino]

Ok that didn't last long, now Pytrack() also hangs consistenly for me. Not sure how it worked before.

Commeting the lines as @bartp said sidesteps the problem, until it fails for me with ValueError("Incorrect Product ID") on LIS2HH12. whoami is returning 0x00.

Are you still with Pytrack firmware 0.0.3 @bartp?

[livius]

@daniel is this ok?

if (memaddr > 0xFF) {
        if (!mp_hal_i2c_write_byte(self, memaddr >> 8)) {
            goto er;
        }
    }
    if (!mp_hal_i2c_write_byte(self, memaddr)) {
        goto er;
    }

i ask about if (memaddr > 0xFF) {
if it is lower, then only one byte is written?

how device can distinguishe it then from data bytes?
I suppose that this if is unnescessary - but maybe i am wrong (i am not an expert).

[bartp]

@jmarcelino Yes, I downgraded only the LoPy to 1.7.3b1. Pytrack (both modules I have) are running 0.0.3. That works ok.

[jmarcelino]

@bartp
Thanks, so it's unrelated to 0.0.3 and more likely an issue with I2C on 1.7.5, maybe to do with what @livius found.

Makes sense..

I'd hope Pycom would test their releases with their own official add-on boards. I think people quite rightly expect at least these to always work.

[bartp]

@jmarcelino @daniel Personally I think better documentation of what code needs to be updated is essential. I noticed there were updated libraries, updated pytrack firmware, so I assumed I had to update all of them to be 'in sync' with Daniel.

Perhaps it's best to reference to the corresponding change log in each firmware announcement, and mention any pytrack/pysense updated you need to do first.

Anyway, I've no doubts the engineers at Pycom are working full force to bring all promised features into the firmware.

Hi all,

I ran into this bug yesterday upon testing and I'm pleased to share that it's been resolved now :)

Daniel will be releasing an patch for the bug later today, it was an issue related to readfrom_mem in the I2C class (1.7.5b1). I'll update here when it's patched and uploaded.

We're working on a methodology for better tracking releases and fixes. I have some ideas and thoughts on how we can best handle this publicly but am open to suggestions.

Thanks!

[bartp]

@bucknall @daniel Ok, thanks! Looking forward to the new release.

[daniel]

Hello,

The issue with the readfrom_mem method has been solved. The new release is out: https://forum.pycom.io/topic/1423/new-firmware-release-1-7-5-b2

Cheers,
Daniel

[bartp]

@daniel Confirmed! All is working nicely again! Thanks for the update!

Regarding the original topic; is there a changelog of Pytrack firmware 0.0.3 available?

[bucknall]

@bartp On my current todo list is compiling a release notes page on our docs for LoPy/WiPy/SiPy Firmware, Pymakr Plugin, Pytrack/Pysense Libs and Pytrack/Pysense Firmware. Please bear with us as I'm involved in a number of different projects and am aiming to have this up by the end of next week, followed by updates to it every time we update any of those products

[bartp]

@bucknall Sounds good! Ok, we gaan met jullie beren...
