LED ON OFF through UART I have same type copy in our code but not working LED ON but extra character comes and when type LED OFF and then enter not off pls help me
Good day, I've stumbled upon your RU-vid stm32 series and am interested to buy one of your courses. I am an electronics student and new to stm32 programming. Our curriculum covers mostly the HAL aspect of the programming process. Which course of yours would you recommend? I like your teaching!
I'am really thankful for this important video because I have prepared all steps even the Blynk app project but nothing goes because the computer didn't find the ESP8266 ! Thanks again
Привет, уже долго пробую и ничего не выходит. Прошивка успешно загружается. Появляется WiFi точка, но на AT команды не реагирует. Также не реагирует на скечи с кодом. Что делать? Hi, I've been trying for a long time and nothing comes out. The firmware is loading successfully. A WiFi hotspot appears, but does not respond to AT commands. It also does not respond to code snippets. What to do?
I don't know what's wrong with my project but when I try the LED won't be turned on at first, i can't upload the code from arduino IDE if using the pin 0 & 1 for RX TX but then I try to use SoftwareSerial library to define pins 10,11 to be RX TX is it correct? or it must be on pins 0 & 1 for RX TX? I use the apk in the link, it could be connected but the led won't be turned on when i clicked on.. Any solution would be appreciated🙏
Hi Orfigeminkch, when we use Arduino Pins 0 & 1 as Rx, Tx to connect to HC-05 Module. Arduino won't allow us to upload the code. That's why in video I mentioned that first upload the code and then connect HC-05 Bluetooth module to Arduino's Rx and Tx pins. This way we can avoid issue with code uploading. Otherwise using Software Serial is an option. Now when you use software serial library make sure use software serial to receive data. This will leads to change in Arduino code. I hope this may help. Good luck and best wishes!
Nice, thanks the example. Would you have any tips for using a ESP32-C6 sending data to zigbee2mqtt which forwards the data to a server which responds with a payload which is sent back to the ESP32-C6?
Hi Madtin, usually only at the time of esp32 programming happening the LED keep flickering. Blut once the programming is done then LED blinks as per delay in the code. I hope this answers the question. Good luck and best wishes!
The constants used both in the video and in the comments below are erroneous. Gave no output. I removed the extra U (??) and made all 4 bytes long (not 4.5) #define ITM_TRACE_EN *((volatile uint32_t*) 0xE00000E00) #define DEMCR *((volatile uint32_t*) 0xE000EDFCU) #define ITM_STIMULUS_PORT0 *((volatile uint32_t*) 0xE00000000)
Hi Rabbunimerugumala, I suggest to install the drivers as shown in video and if it doesn't help then please try with other good quality microUSB cable. I'm sure it will help to get your NodeMCU ESP8266 detected in device manager. Good luck and best wishes!
