Try setting baud to 230400 if not reliable at 460800.... Lot depends on the setup here.

I also tried 921600 (the FTDI chip 'should' cope) - but no joy. I'm running the esp32 on a 'marginal' power supply (I've noticed a few brownout errors) - which might affect things?

Had some difficulties getting this to work 'reliably'.... So I upgraded to the latest (possibly) version of esptool. This is now an .exe file - and I'm wary of breaking my esp32 build environment. In (your esp-idf install directory) \components\esptool_py\esptool - rename esptool.py esptool.bak Add ...

Its https://www.arducam.com - i see there are now boards for it to plug into with usb support.

As mentioned - adding -z to the command line allowed me to program it - although needs me to hit reset and short in0 to gnd.

I was trying to get an ESP32Cam board working from within Flowcode - This is programmed VIA an FDTI converter. FC - itself 'seems' to offer the ESP32-Camera board - I went with this - but upload doesn't work as is. (Note you need TX->UDR and Rx to UDT, IO0 to Gnd - and need to press reset to init pr...

An alternative technique... Read the entire port and then shift to get the required bit.. Have something like: Where .n is the variable holding the bit you want to read and .p is a variable as 'wide' as the port (so byte for 8 bits or long for esp32 (32 bits port)). .p = Input() // Read the whole po...

Here I stuff the values into a second TypeConversion - and display the result... Seems to work okay.. Type conv.fcfx Note - one source of problems is that some values don't have an 'exact' representation as a float - so 3.000 might be 2.9999999 or 3.0000001 (probably not 3.0 - just an example of wha...

Type conversion should work either way.

If you can post a sample/pm your code I'll take a look..

Strings can be passed by reference or value - reference just passes the address and any changes made are passed back. Make a local copy does exactly that (so passed by value)- so any changes are kept local to the macro. Note that the box is 'checked' but not selectable for arrays but these are all p...

You need to add '.0' after one or both of the numbers - so 24744.0/244.0 would do the trick..

I used the UART instead of a LCD - for ease...
