  • More SD Card Write Details

  • Had to dig into the FPGA code for the SD card. Using Neal Crook's documentation of Grant Searle's version (longer pedigree on the page). The status register values are: // SD_Status bit values from Neal Crook's documentation of Grant's SD card // b7...
  • We get signal

  • Indeed, immediately after running the Windows software in a VM with the device connected I was getting a live data log of the CO₂ concentration! This screenshot shows me breathing into the vicinity of the sensor:Ok, time to disconnect the device from...
  • How ESP-NOW really works ?

  • To implement the ESP-NOW Protocol, we first need to understand how it works in details. The datasheet doesn't say much on the really low level, especially on the acknowledgment behavior. To understand what ESP-NOW does, I use Wireshark with my PC Wifi...
