Data Logger using STM32 || ESP8266 || Thingspeak

[@safridwikurniawati8094]

Hi, why I can't send my multiple data sensor SCT 013 using DMA to thingspeak ?

You are amazing. I haven't tried it out, but if it works i'm gonna be very happy!

[@muhammadhaziq5542]

I managed to do this tutorial with ESP8266-01, LDR sensor, and STM32F103C8. The only thing that I need to change is to use a crystal clock.

[@JoelAnth0ny]

I have been debugging for over a week. My code gets to ESP_init and then appears to get stuck in the Uart isr. I am not sure when it is supposed to move on from ESP_init but my code gets stuck there. Not sure if I'm not understanding the code right or if I'm not getting good connection to my ESP-01

[@JoelAnth0ny]

Nvm. I figured it out. My HAL_Delay wasn’t long enough after AT+RST because my clock was configured differently than yours. Also after (AT+CWJAP…) wait for waits for “GOT IP” but my ESP was sending “OK” so changing that field to OK solved the problem. Hope this helps anyone having similar issues

[@bonziqin7341]

I had a problem when I added the library. "Error: L6200E: Symbol huart1 multiply defined (by uartringbuffer.o and main.o)" Can you help me fix it please.

[@lanvuthihoang7227]

I fixed it by copying the library and putting it into main.c, and removing the old library (UartRingbuffer.c) It worked, but I still want to know how to fix the UartRingbuffer library or main to work as your tutorials. Thank you so much

[@ControllersTech]

In the uartringbuffer.c, where the huart1 is defined, put extern in front of it.

I'm using STM32WL series custom board with Esp32 C3 mini is connected via uart. But I made the necessary changes according to your tutorial, my program got stuck on ESP_Init() function, therefore not going to the while loop.

[@ControllersTech]

ESP32 is itself another MCU. Here I have used the ESP8266 module. They are different.

[@MahadiHasan-qi1cb]

@@ControllersTech What changes do I need to perform inside ESP_Init() function, Is there any possibility to make it work with your libraries?

[@MahadiHasan-qi1cb]

@@ControllersTech I was looking into the ESP_Init() function and step into RingBuf_Init() and Also Uart_sendstring() function, it looks like only a single letter is for RingBuf_Init() like "a" even though it should be "abc" for "SSID" and "1" it should be "1e1" and for Uart_sendstring() sending only "A" not the "AT+RST ".

Sir ı have a bşg problem. I have been trying to solve it for a week but u couldn't. I wrote the same code on my stm32f429, but ı cant see the datas on thingspeaks server. I dont even see my adc value on stmstudio. Rx and Tx is correctly connected, ı double checked it. What is the problem ? I uploaded my esp to at commands also. It responds OK when ı write AT. What can ı do sir, please help me.

[@ControllersTech]

you need to debug your code and find errors. Just put breakpoints and check where the code is getting stuck. PS: No code will work without debugging

but you have used the node mcu, it has also one EN pin so like ESP8266-01 , we should make EN pin of node mcu high??
