Re: IDF 4.0.1, esp-iot-solution\examples\touch_pad_evb and ESP-Tuning Tool

This is now working in new V1.1 commit. (bugfix(touchpad): add Kconfig file)
Thanks to alic-maker for fixing this.

IDF 4.0.1, esp-iot-solution\examples\touch_pad_evb and ESP-Tuning Tool

I have installed IDF 4.0.1 and downloaded the recent esp-iot-solution V1.1. I can build the touch_pad_evb example and load it onto EVB V3 successfully. I now want run the ESP Tuning Tool. "idf.py menuconfig" does not display the necessary menu items to enable the tuning. When I run the ESP Tuning To...

Re: ESP32 failing IEC61000-4-6 (Conducted Immunity).

Hi,
only the PCB Touch functions seem to screw up.
The PCB drives a DAC, a relay and some LEDs. These all seem to behave OK.

Any ideas, anything I could tweak would be welcome ...
Thanks

ESP32 failing IEC61000-4-6 (Conducted Immunity).

Hi, we have just had our ESP32-based PCB fail IEC61000-4-6 (Conducted Immunity). The PCB is a simple control panel with 4 Capacitive Buttons (using the ESP32s Touch Capability). When the buttons are operated while the test is in the 280KHz band, the PCB invariably locks up (buttons don't respond). (...

PSRAM with WROOM32

Hi, I have a custom design based on WROOM32 that we now want to add more software functionality to. We are unfortunately running out of SRAM space. I wonder should I just migrate to WROVER32 ...... or is it viable to just add external PSRAM to the WROOM32 ? I have read the postings about adding PSRA...

Re: DMA to 8-bit shift register for GPIO pourposes

I'm currently designing (only in planning phase yet), my own dev-board for the FT813, and planning to convert the arduino lib I linked to ESP compatible.) Did you get QSPI to FT8xx working ? I guess SPI is easy, as there are code examples, but I cannot see very much information about using QSPI on ...

Re: spi driver for lcd interfacing

FWIW, I've gathered Sermus' LCD "HVAC" demo - as modified here for the ESP32 - into a repo. I forked Sermus' original repo and applied and credited the changes made by Rudi, Nilay, and myself (to get it to work). This has NOT been updated to work with the latest toolchain (it currently works with t...
