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.
