Re: Porting esptool.py to C
Kolban, Happy to compensate for your time. Our only requirement is to be able to take a binary file and be able to reflash an ESP32 over serial, with the code capable of being run on an STM32L4 (straightforward uart write functions, and we use a DMA to read from the UART to a ringbuffer but that can...

Porting esptool.py to C
We have an embedded device connected to the ESP32. We would like to be able to remotely reflash the ESP using our other microcontroller. 1) Does anyone have any idea of the required complexity in porting the protocol to C? 2) Is there any interest from the community in doing said porting if we paid ...

Re: Cannot use GPIO17 for UART0, UART1, UART2 TX - causes guru mediation errors.
thanks. it seems that documentation was only just recently added to the datasheet. I wish it had been in there before we designed our PCBs. Also, it's only mentioned in a side not, but not listed in the pinouts section - I suggest it's added there as well with an asterisk.

Cannot use GPIO17 for UART0, UART1, UART2 TX - causes guru mediation errors.
I'm cross-posting this from the arduino-esp32 forum. We have the exact same problem with the ESP32 IDF. Whenever we try to write to GPIO17 the system faults. Hardware: Board: Custom CPU: ESP32-D2WD Core Installation/update date: ?Jan 12, 2018? IDE name: ?Arduino IDE? Flash Frequency: ?80Mhz? Upload ...

Re: ESP32 specifiaction
Actually, this isn't clear to me at all. When talking about the 'N-bits' of an ADC, it's commonly understood that you have a range of values from 0-(N^2-1) for a total of N^2 divisions (assuming non- 2s complement encoding). 13 bits would equal a range of 0 - 8191. If the range is truly 0-4096 then ...
