How to transmit image from esp32-cam to pc

[media_user1]

Recently i want to made a project weight scale with esp32-cam taking the picture. To show the weight scale result im using python gui serial monitor, and an i2c lcd and to send the image im using ftp client. im already tried to receiving image using my android ftp server, but not implemented yet in my python gui. But whenever im using the wifi my lcd not showing any result

lcd only work when not using the wifi. Is it because the board not provide much power to lcd or something?
Im using hx711 to read loadcell sensor, pcf8574t i2c expander, and ftdi programmer to supply esp cam

If i cant using wifi, is using serial possible?

ftdi programmer to supply esp cam

As a power supply? That may be your problem, those FTDIs generally can't deliver enough power.

ok here if im using my mb102 board supply, and still no result but much brighter than using ftdi board

and here if im using code without initialize wifi, but the difference is i need decrease the contrast level in the i2c expander so i can see the result(before decreasing the contrast level, the result is same as photo above but the visible word is masked by those white block)

so its still less power than it needed?

Possibly. Make sure you have some power supply that can at least deliver 500mA plus what the LCD requires.

already tried with molex cable from my pc powersupply, and still get same result as i used board supply before.
also dont have any multimeter to try measure the current, maybe i need to find one now
