Linker Bug?!?
LOTS of debugging of random crashes - boils down to this: My Code: #define RC_CHANNELS 6 unsigned long rc_val[RC_CHANNELS]; When I do: ESP_LOGE(TAG,"rc_val ptr is at %p size is %d",rc_val,sizeof(rc_val)); As you might expect - it tells me: E (1972) CouchLED: rc_val ptr is at 0x3ffb2a84 size is 24 (B...

Re: Simple RMT pulse receiver
> Make sure to also de-clockgate and un-reset the RMT peripheral. @ESP_sprite how do I do that? I added the following - still no interrupts: #include "driver/rmt.h" #include "soc/rmt_reg.h" #include "soc/rmt_struct.h" #include "esp_intr_alloc.h" #define RMT_CHANNEL RMT_CHANNEL_2 #define RMT_GPIO_NUM...

Simple RMT pulse receiver
I need to write RMT code that doesn't use the RMT driver, and instead bit-bashes and manually sets up GPIOs and interrupts to work. (It has to do with EVENTUALLY needing this to work in conjunction with another piece of code that transmits - and the driver's difficulty to do both at the same time). ...

RMT: Transmitting and Receiving on two different channels at same time
I am working in ESP IDF 4.4.2 I have some off-the-shelf code that I'm working with that do two different things, and both work: * A library that uses RMT to transmit words to a Neopixel strand * A library that uses RMT to sniff servo waveforms from an RC remote control receiver But when I try to use...

Re: RMT based NeoPixels (WS2812B) flickers when WiFi is used
I don't want to get TOO deep into the answer here (considering this thread is soooo old) - but the answer is that the Neopixel handling is very timing sensitive - particularly when you have enough pixels that the data being transmitted has to span more than a single RMT buffer. This means that if yo...

Re: LEDC (hpoint, demo issues)
P.S. It seems as when I set the max duty cycle to 8192 - that made the "fade" work full scale (0% to 100% PWM). But that actually help reveal that the following code doesn't seem to be doing anything: printf("3. LEDC set duty = %d without fade\n", LEDC_TEST_DUTY); for (ch = 0; ch < LEDC_TEST_CH_NUM;...

LEDC (hpoint, demo issues)
I'm building and running the stock led fade example. It doesn't seem to be working correctly. Biggest question is the two set-duty examples are supposed to set it to "0" and "test". But in both cases they do 50/50 duty cycle all the time. This is true for BOTH tests. The other weird issue is that th...

Bumping this ... because several projects are stuck on this. Any idea?

Re: Error: fatal error: mbedtls/config.h: No such file or directory
I am having this exact problem - and it is also trying to migrate 4.1 code to 4.2.2 I did what you said here - and there are MANY references to: -DMBEDTLS_CONFIG_FILE=\\\"mbedtls/esp_config.h\\\ in the compile_commands.json file. There are are a few contentenders to what this could be in my esp-idf ...
