Re: Help getting a Noritake Itron VFD working on the ESP32

I agree with ESP_Sprite, as that is the first thing to check.
Correct me if I am wrong, but I think your ms delay is wrong.
I think it should be:

Code: Select all

#define _delay_ms(x)   vTaskDelay( x / portTICK_PERIOD_MS )

Re: Debugging a deadlock/hang

Just FYI, The other does not do anything, it's used to manually put it into programming mode. it stops logging and responding to network requests. printf, is one of your greatest helpers. Just create another task that spits something like the time to the serial port every second. If that stops worki...

Re: Multiple Applications from SD card

I wonder if you could remove the SMC option to simplify it. Use OTA1 when it boots to read the uSD and copy the app you want to PSRAM. When that is done re-boot using PSAM. Of course you would have to disable the RAM testing stuff in menuconfig.

Re: Deep sleep power consumption with connected SPI device

It's nice that you have this on a breadboard, because it will make it easy to isolate the problem. The way I would first tackle this is first to bring UC's CSA pin to +3.3v. If no uA change then bring BMA's CLS to +3.3v. IF still no change, then then disconnect the MOSI line, then MISO, then CLK, to...

What format is in the docs folder

There is a folder: C:\msys32\home\Mike\esp\esp-idf\docs\en

What are the files with a .rst extension. I can open them in a text editor, but why .rst and not .txt ?
Is there some other application that opens them up ?

Re: What would you like to see in The Next Chip?

It's like a laptop with an i3 CPU but an IDE HDD. Fast CPU and slow HDD results in slow overall system.
It's like a laptop with an i3 CPU, and 384k of ram. Fast CPU and little memory results in slow overall system. :D
