Hello, I am making a thread to share our experiences building our own tangara's from the sources.
First, thank cooltech crew for sharing this great project. And thanks a lot Jacqueline for your support so far.
I have assembled two mainboards, and one faceplate.
2 mainboards, because I thought the first one was failed and hope I'd have more luck with the second.
Truth is, I don't : )
Both boards power on, and I can run commands from the console using minicom. But except that everything seems frozen. I can change the display brightness and see the pwm duty cycle change on the ESP32 corresponding pin ; so something runs, but except that the clock signals (SPI clk for example) are 0V. I have a few clock cycles at the power on and then it stops (and the screen is stuck saying it can't read sd card)
I'll continue debugging my connections, but it the meantime : has someone seen the same problem ? to me it is weird that the esp32 stops the clock on SPI. Is there a command to (re)start SPI from console ? has someone experienced similar problem when building ?
Cheers
Eve
