WROVER and RGB LED

I bought a WROVER board. It has an RGB LED on it. Looking at the schematic found here: https://dl.espressif.com/dl/schematics/ESP32-DevKitJ-v1_sch.pdf I find that the control for the RGB should be GPIO2 (red), GPIO0 (green), GPIO 4(blue). When I set GPIO2, GPIO0, GPIO4 to output, I find that setting...

Re: Any Database connect (odbc like) ?

You can use a REST API to access some no-sql databases. I use REST requests to access CouchDB in some of my projects.

Purpose of GPIO_OUT_W1TS_REG

Reading the tech reference, we have two registers called GPIO_OUT_W1TS_REG and GPIO_OUT_W1TC_REG which apparently are Write One To Set and Write One To Clear. If I understand these correctly, Writing a 1 in BITx of GPIO_OUT_W1TS_REG is the equivalent of setting the corresponding bit in GPIO_OUT_REG....

Re: Core dump

Howdy, In my experience, it is always better to provide as much information in a post as possible. Things like context, what your app was doing, did it ever work, what source statements were being executed at the time. In addition, I am a strong proponent of including source and full data. I do **no...

Missing C struct for IO_MUX_x_REG?

I have been enjoying/appreciating the C structures mapped to the registers that can be found in soc/esp32/include/soc. I was looking at the tech ref documentation on the register called IO_MUX_x_REG and seem to find this referenced in "io_mux_reg.h" ... however, I am not finding an equivalent C stru...

Re: I2C communication

Have you attached a logic analyzer to the I2C bus (CLK and SDA pins?). I have always found examining the protocol on the bus to resolve most of the issues I have had.

Re: [Info] MQTT Eclipse Paho client component

Its been 5 months since I looked ... but if I remember ... we take the whole folder found here: https://github.com/nkolban/esp32-snippets/tree/master/networking/mqtt/paho_mqtt_embedded_c And place that in our ESP32 project's components directory. This would end up with: <YourProject>/components/paho...

Re: Monitoring serial output without reset

The "make monitor" does appear to perform an ESP32 reset ... however if your ESP32 is running, executing a local serial terminal client such as putty or screen connects to the serial port without resetting and you will start to immediately see your output without a reset.
