Trying something on the side at the plant: an ESP32-CAM pointed at the filler infeed, to send a „jam“ flag to Hermetry when bottles pile up. Bought one with an FTDI adapter.
In the Arduino IDE (2.3) I pick the board „ESP32 Wrover Module“, then Sketch > Upload Using Programmer, because a video said that’s how you flash with an FTDI. Get:
No programmers available for this boardProgrammer menu is empty. What did I miss?
Can you watch it in Hermetry’s camera live view once it’s flashed? Been wondering about these.
„Upload Using Programmer“ is for AVR boards with an ISP programmer. ESP32 boards don’t have any, so the menu is empty. The FTDI is a plain serial port here, use the normal Upload button.
What works for me every time with these boards:
- Board: AI Thinker ESP32-CAM (it’s in the esp32 package).
- FTDI at 5 V to the 5V pin, GND to GND, TX to U0R, RX to U0T.
- Bridge IO0 to GND, press the reset button, then Upload.
- When it says Hard resetting, remove the IO0 bridge and press reset again.
@Michael no. Live view in Hermetry needs an H.264 stream, and the ESP32-CAM serves MJPEG, which is never played. For a jam flag that’s fine anyway, you only send a number.
Normal Upload with IO0 bridged and it flashed first time. I’m sending jam as 0/1 rather than true/false so it charts. Thank you.
Shame about MJPEG but makes sense, thanks Aoife.
