Re: I2C does not work on pins (36,37) of ESP32S3 R8

Thanks a lot for taking the time. Is it correct to say that by disabling this , I just disable the capability to add an external PSRAM to the board? it does not affect the normal PSRAM operation internally in the chip, right? I really appreciate if you could give me more info about how to reassign S...

Re: I2C does not work on pins (36,37) of ESP32S3 R8

Do I need to have access to PSRAM? Can I disable that so I can use the pins?

Re: ESP32S3 - Possible to disable PSRAM??

Hi @meisner

I am having the same issue. trying to get pins 36 and 37 to work with I2C. Could you please explain a bit more about how you solved this problem.
How do you disable that feature to free up the pins? I am using Arduino code to flash.

Thanks

I2C does not work on pins (36,37) of ESP32S3 R8

Hi I am reading a gps module data. I have a code that runs properly using pins (7,8) for I2c communication on ESP32S3 R8 on my prototype board. However, on the designed pcb, the I2C pins have changed to pins (36,37). This change has made gps stop working. I did try the same (36,37) pins on my protot...

assert failed: xTaskDelayUntil tasks.c:1477 (( xTimeIncrement > 0U ))

Hi I have a very generic cpp code in ESP IDF to be used for a multi rate task program on ESP32 S3. The code has a base rate of 1 ms and rate1 of 10 ms. The code builds with no error. However, the board keeps rebooting with the following error: --------------------------------------------------------...

Re: ESPNOW Works But Sometimes Outputs Garbage Randomly

Thanks for your help.
I am new to this and I really appreciate if you could help me a bit further. What do you exactly mean by "dangling pointer"? how would I know if I have it somewhere? and How would I avoid it?

Thanks

ESPNOW Works But Sometimes Outputs Garbage Randomly

Hi I have setup communication between two ESP32 S3 boards. and I am sending an array of size 10 from one to another: uint8_t Test[10] = {0,1,2,3,4,5,6,7,8,9}; I do not get any error and the code builds properly and connects to the other board imminently but sometimes I get garbage output on the rece...
