Re: Can ADC work while wifi is on?
ADC 1 has 8 channels that you can use. Do you need to use more than 8 channels for ADC sampling? It is true that ADC2 does not work if you have Wifi on. ADC2 is used by the Wi-Fi driver. Therefore the application can only use ADC2 when the Wi-Fi driver has not started. If you really need more than 8...

Re: Fixing IP Address for ESP32 and PC Communication
Thanks for your reply arunbm,
So just to clarify,
"there goto DHCP reserved.
Assign a IP along with mac..Thats it.."
I will do the above two steps on the router website right? Each router whenever I setup requires a website that I can log-in, setup the wifi name and password.
Thanks

Unable to Make OTA Demo to Work
Hi Everyone, I am currently trying to make the OTA example to work by following this link's instruction: https://github.com/espressif/esp-idf/tree/master/examples/system/ota The below are the steps that I did: 1. My PC is connected via ethernet to my wifi router which my ESP32 is also connected to 2...

Re: Timer Interrupt cannot Run Faster than 100Hz?
Thanks for your help. You mentioned flash write in the last reply, and I wonder what this really mean. Is there a task that runs flash write in the background? How do I know how often this task (if exists) runs? Is there away that I can maintain 200Hz task precisely? I really appreciate if you could...

Re: Timer Interrupt cannot Run Faster than 100Hz?
Hi, So it seems the interrupt-triggered task is able to run 200Hz when there are no other lower priority tasks running alongside. Since I have 2 other tasks run along with the interrupt-triggered task, sometimes the interrupt-triggered task was not able to run at the precise timing due to being plac...

Fixing IP Address for ESP32 and PC Communication
Hi everyone, I am not very good at network programming so I hope that someone could give me some directions to try. I have a PC communicate with ESP32 via TCP/IP. The ESP32 is a server and PC is a client. As you already know, the PC requires the ESP32's IP address and port in order to establish a co...

Timer Interrupt cannot Run Faster than 100Hz?
Hi everyone, I have a program that has a timer interrupt with each tick is 1us . The timer interrupt triggers xSemphoreGiveFromISR to ADS1256_Collect task that simply toggles a GPIO (see code below) The below is the code: #include <stddef.h> #include "esp_intr_alloc.h" #include "esp_attr.h" #include...

Re: How to introduce sequential tasks using xEventgroupSync()
I am not sure if that is what I wanted. I would like to maintain a fixed timing offset between the sending task and the receive task, and both of them will run infinitely.
Would it is possible to achieve this? Assuming that there is no packet resending or congestion.
Thanks
