      C

      I am experiencing the same symptoms with my M5Paper and Windows 10. If I run and download an m5 file that contains about 1400 blocks it does not work, but if I delete the blocks to make it about 400 blocks it works. M5 paper This problem occurs with all combinations of UIFlow-Desktop-IDE (Win) v1.0.16, v1.0.17 and firmware versions v1.7.7, v1.7.8. A sample m5 file (about 1250 blocks, the event also occurs with this file) https://github.com/collelog/m5paper-dashboard/blob/master/src/weather-jp.m5f These m5 files used to be able to be run and downloaded in conjunction with UIFlow(Web), but UIFlow(Web) is no longer available, as shown in the following topic. https://forum.m5stack.com/topic/3361/uiflow-cannot-currently-connect-to-any-m5stack-devices

      It is definitely something to do with the size of the program. Once it reaches a certain size it will no longer run. All I have to do is delete anything (reducing the size) and it will run again. I provided a sample of my code to tech support and they are working with engineering to investigate.

      @bobolink FYI to myself If you have an engineering background--part of Micropython-- module 'dba: calculate dBA (A-weighting decibels) from an input stream of digital audio samples module 'i2stools': function to efficiently extract sample data from a buffer filled by I2S Signal processing (logical shifts--fractional multiply) on the PCM samples instead of hardware volume control gets the job done also.

      Core 2 and GPS Pins Still To Short

      Just a follow up. I contacted M5Stack tech support and they told me the old modules have pins that are 2.5mm and the new board has pins that are 3mm. So in theory I have the newer board but it separates from the Core2 fairly easily. Meaning the pins are probably making contact but not great. Will have to get longer screws and screw the module down to ensure good contact. For reference to separate from the Grey Core it is very tight and I usually use a screwdriver. I measured and the Grey Core lets the pins seat approximately 1mm more than the Core2. Here is a picture showing how to measure pin length.

      Hello @SE thank you for sharing. The answer is not really surprising though - the required SDCard detect pin is not connected at all according to the schematics of M5Stack (Fire, Gray, etc.) and M5Core2. Interestingly it is connected in M5Paper, so SDCard detection should be possible there. But before you get your hopes up - SDCard support is not available yet in the UIFlow alpha version for M5Paper. Thanks Felix

      @se said in Core2 Port I2C Not Working: Felix thanks for the suggestion. You were absolutely correct version 1.7.0 resolved the problem. Now in 1.7.1.1 this problem was fixed.
