Hello,

I confirm that I was able to use UART 0, 1 and USB,

BUT, to do so, I had to change the configuration files using these values (sorry it's a mess):
ESP-Driver:USB Serial/JTAG Configuration is enable,
# CONFIG_APPTRACE_DEST_UART0 is not set
CONFIG_ESP_CONSOLE_USB_SERIAL_JTAG=y
# CONFIG_ESP ...

Hello,

My project uses an esp32C" super mini.

I need to send/receive data to the PC using the USB connector. As far as I understand, this uses UART 0

I also need to send data to a serial client (A), at 115200 baud
And I need to receive data from a different serial client (B), but at 9600 bauds ...

Hello,

I have an issue with a project based on an esp32C3 super mini board.

My project has 3 stepper drivers and therefore an external power supply.
But it also needs a PC connection through the USB cable.

The problem is that, very often, but not all the time, when I connect the power to the ...

Hello,

Here are the schematics:
Of interest, an esp32c3 super mini board in the center, which has a usb c connector with the usb 5v vbus exposed.
on the top left the 12v barel connector (VCC) which feeds in a 12-5v dc-dc convertor (just bellow it the schematics) which is connected to the super mini ...

Hello,

I have a project using an esp32C3 super mini board.
The problem is that I have 2 use cases.

In both cases, I have 12v comming in for the steper motors.

In use case 1 the system does not have a PC connection and the esp32 is powered from the external 12v through a dc-dc regulator to the ...

Hello,

I am using an esp32c3 super mini board.

I have some external stuff connected on pins 20 and 21...

Unfortunately, it looks like there is some chatter there at boot time, and/or when I connect the esp to the USB...

Is there a way to disable these other peripherals using these pins (what is ...

Hello,

Yes, it is for a stepper

The 2 requirements are:
- The pulses duration (both 0 and 1 parts) will need to vary over time (slow, at first, getting shorter, a steady phase (short) and a slow down).
- I need to "program" an exact number of pulses

A typical pulse sequence might have around ...

Hello,

I'll be darned! I was certain that it was a dual core :-(

Ok, back to planning.

What is wrong with using the SPI to send a pulse which can be of variable size?
They are 3 phases to any movements.
Acceleration phase, regular speed and deceleration...
With a SPI speed equal to 4 times my max ...

Hello,

ok, I have tried to pin my task to core 1... But this does not seem to work! I get a crash with the following error:
xTaskCreatePinnedToCore(HWTask, "HWTask", 2048, nullptr, 2, nullptr, 1); << DOES NOT WORK
xTaskCreatePinnedToCore(HWTask, "HWTask", 2048, nullptr, 2, nullptr, 0); << WORK ...

Hello,

With regard to creating tasks pined to core... This is something that I know prety much nothing about. Could you help me, give me some pointers?

As far as I understand the usual way to work on the esp32 is for core 0 to handle the "system stuff", which includes the wifi handling while core ...
