Texas Instruments CCSI Frame
Hello, for an LED Matrix I need to talk to an TLC6983 Chip with an CCSI Frame format. This means "Continuous Clock Serial Interface". Looks like this: ccsi.png Clock needs to be present all the time as the matrix chip has no clock internally but uses the input clock signal from the host device to sc...

Re: How to remove PWM signal from GPIO14?
Thanks for all the efforts.
I found, that the Solo Crashes because of mem issues and core issues.
I set Single Core operation in RTOS and reduced heap size for tasks.
Now it is working as expected!
Best regards

How to remove PWM signal from GPIO14?
Hello,
right after Boot, the PIN14 outputs a PWM signal.
But I need to use this pin as normal PushPull Output.
How can I remove the PWM signal? Nothing I found in the forum helps (gpio_reset_pin() or ledc config).
Can someone help me please?

Re: Component Compile Problem
Got it... was my own fault.
I tried to reference a static function
Move along - nothing to see here.

Component Compile Problem
We created a project from the blinky example. And we added an own component to that project like this: 01.png so the component itself uses i2c so I added following lines to CMakeLists.txt: [Codebox] idf_component_register(SRCS "mc_adau1701.c" INCLUDE_DIRS "." REQUIRES driver) [/Codebox] Editor shows...

Re: Higher Motor PWM Frequency?
My workaround at the moment is to change the prescaler of the mcpwm module directly in the idf driver folder: MCPWM.png However, this is not the best solution as the IDF should not be changed permanently because of updates etc. But one suggestion: If the DEVs put in a #ifndef / #define a user could ...

Re: What is the meaning of rst:0x1 (POWERON_RESET),boot:0x2
It seems that you have tied the "BOOT_SEL" pin to GND. Than the ESP32 boots in download mode for flashing new firmware. Make sure the Boot_SEL Pin is high or floating to boot in normal operation mode. Here you can find all the boot messages. https://github.com/espressif/esptool/wiki/ESP32-Boot-Mode-...

Higher Motor PWM Frequency?
I need a complementary PWM with dead time generation of 150 kHz. Here is a quality graph of the PWM Signal I need. Duty Cycle needs to be 50 % and frequency 150 kHz. PWM.png So I thought I use the MCPWM module for that, but I recognized that the maximum frequency is about 2 kHz. When going higher th...
