You can see server stats for it at https://atari8bit.net/fujinet/ it might help you visualise what is going on. How do you get the stats of the tnfs-server for output & formatting? I'd love to do this when I put mine online. Quote Link to comment Share on other sites More sharing options...
Mr Robot Posted February 8, 2021 Share Posted February 8, 2021 Shell scripts run by cron produce text files and upload them to my webserver. The website reads the text files, parses them and outputs data using php. I'm being too aggressive in my log clearing so some of the stats aren't reflecting reality. I need to put a little db in place that stores the mounts so I can get the data back in a more flexible way. EDIT: Thanks to bocianu there is now a usage log so I don't have to scour syslog any more!

I moved it to a SMD pad that can accept a metal snap dome or just be shorted with something metal. It's not really needed since we use a button on GPIO to do a "safe" reset. The power switch is effectively a hard reset. I opted to have the smd pads "just in case". 1 Quote Link to comment Share on other sites More sharing options...

I think the file esp32 system lib only supports fat16 or fat32 (afaik exFat is not supported). Windows can only format fat32 up to 32G. There may be utilities for windows to format larger or you could format it with Linux Quote Link to comment Share on other sites More sharing options...

It really depends on the card type, I have successfully used a 64G card. It's really sort of pointless, just grab a 2G SanDisk for it, and be done with it. -Thom 1 Quote Link to comment Share on other sites More sharing options...

A couple weeks ago I bought a pair 32GB Sandisk cards for under $8 each without even doing any comparison shopping to save a few bucks. The 16GB versions were like $11 each. I didn’t even bother looking at anything smaller, as most of those I saw listed were oddball weird-name units that I couldn’t bring myself to trust. So my suggestion to folks is just buy some good-quality 16GB-32GB cards from Sandisk, Samsung or whomever plus a few spares and be done with it. 4 Quote Link to comment Share on other sites More sharing options...
+mytek Posted March 15, 2021 Share Posted March 15, 2021 Not sure if this is a firmware issue or a hardware issue, but I was looking at the FN webapp tonight and when checking the SIO voltage it looked quite low. But when I put a voltmeter on the IO35 pin it was at 3.3V which I would think is the top of its range being on a 3.3V based system. So I naturally assumed that 3.3V should = an SIO voltage of 5V unless I'm mistaken. Any idea of why it's so far off the mark? Quote Link to comment Share on other sites More sharing options...
tschak909 Posted March 15, 2021 Share Posted March 15, 2021 One of the ADC's is used to sample the SIO voltage, and it's calculated in this routine: int SystemManager::get_sio_voltage() { // Configure ADC1_CH7 adc1_config_width(ADC_WIDTH_12Bit); adc1_config_channel_atten(ADC1_CHANNEL_7, ADC_ATTEN_11db); // Calculate ADC characteristics esp_adc_cal_characteristics_t adc_chars; esp_adc_cal_characterize(ADC_UNIT_1, ADC_ATTEN_DB_11, ADC_WIDTH_BIT_12, 1100, &adc_chars); int samples = 10; uint32_t avgV = 0; uint32_t vcc = 0; for (int i = 0; i < samples; i++) { esp_adc_cal_get_voltage(ADC_CHANNEL_7, &adc_chars, &vcc); avgV += vcc; //delayMicroseconds(5); } avgV /= samples; if (avgV < 501) return 0; else return (avgV * 5900 / 3900); // SIOvoltage = Vadc*(R1+R2)/R2 (R1=2000, R2=3900) } -Thom Quote Link to comment Share on other sites More sharing options...
Gunstar Posted March 15, 2021 Share Posted March 15, 2021 (edited) 4.78V is exactly what I show on my Fujinet page as well, always has been, and I have my Fujinet powered with an external 5V USB PSU. There was a discussion about low voltage readings off of the Fujinet web config site in another thread in this sub-forum. I remember @DrVenkman and/or @_The Doctor__ talking about it being too low a reading, for me and for someone else who started the conversation who's reading was even lower, IIRC 4.75V. And it was suggested I test my line voltages, so I did. I've tested the +5V off of the SIO, controller port and the PBI I installed; though I was unaware that the Incognito supplied +5V to pin 47/48, so I connected +5V from the mother board during installation. But they all read a rock steady 4.89V from OEM "universal" 31VA PSU. Slightly lower than I'd like, but I've never had an issue so far. I've half a dozen 31VA universal PSU's for my Atari drives and 800/1200Xl, so I may see if I can find one with a slightly higher voltage output and swap them. I haven't tried putting a voltmeter to my Fujinet yet, EDIT: Actually, I just checked my Fujinet config page and it's shows a voltage of 4.757 now! Which, IIRC, is exactly the voltage another user was getting on his. My real voltage from the SIO is still showing 4.89V.

Any idea of why it's so far off the mark? It could be an issue with the code @tschak909 posted. I whipped that up very early on. I have confirmed readings with my multimeter and compared them to the voltage displayed and it's very close, ie, SIO voltage measured at the FujiNet receptacle pin matched the displayed voltage.

+mytek Posted March 15, 2021 Share Posted March 15, 2021 Well to be honest, I did end up tweaking my resistor divider because my actual SIO voltage is the same as Gunstar's at 4.89V and I was seeing 4.78V. So I tweaked the values to bring it up to 3.3V on the voltage sense line, but still got 4.78V on the web app. That's when I really started getting suspicious. So based on what I was seeing, it suggests that the ADC is not getting read, and that the 4.78 is a fixed response. EDIT: I'm not saying this is actually what is happening in the code, but more a description of what it appears to look like based on changing the input voltage and yet getting the same reading.

I opened an issue on Github so I don't forget about it. The only point of it originally was to check if the Atari was on or not. It's no longer used for anything other than the display. If it's not easily fixed or fixable at all, I'll remove it. Quote Link to comment Share on other sites More sharing options...

+mytek Posted March 18, 2021 Share Posted March 18, 2021 Any thoughts on using one of the spare I/O pins (IO12 or IO15) for an SD card detection pin? Since the SD card detect switch is wired with one side to GND, the other side could go to an I/O pin with a pull-up resistor, and then if a new card were inserted, the firmware could be coded to detect that occurrence and issue a Soft Reset to initialize and mount the new card automatically. 5 1 Quote Link to comment Share on other sites More sharing options...

Nice idea! I love the way that the CF based HDD solutions using fjc's BIOS will auto-detect card swaps and just work seamlessly. 2 Quote Link to comment Share on other sites More sharing options...

I'm probably gunna go with IO12 due to the current board layout and IO12 is close to the SD slot. The firmware will need to check for the pull-up at boot and enable this feature if available. Will try to bodge up a board when I have time. 4 Quote Link to comment Share on other sites More sharing options...
