Hi sir. I have a question. The library or driver files that you use (e22900t22d.h and e22900t22d.c). We can use the LoRa modules without these files right? Since the stm32 board run with LoRa as default, as you said before.

Hi sir, thank you for the video and explanations. I want to ask that, can't we use the LoRa modules without using FreeRTOS? Do stm32 boards not include the needed softwares for that?
@usefulelectronics 8 күн бұрын
Adding FreeRTOS is an optional feature. STM32 runs without RTOS by default. So yea you can use LoRa module without using RTOS

@@usefulelectronics Thank you for your response. I made the project to communicate 2 stm32 blue pill boards. When I arrange the wiring just for the UART communication between boards, it works. But after I change the wiring according to the LoRa e22-900t22s modules, it does not work. I am sure about the wiring, parameters like baud rate, channel etc. What could be the issue?

Adding an extra mcb to a hopefully already protected circuit? Don't see any reason... Also not a good way to install an AC unit, it should be on its own circuit with its own mcb.

I think the "MODE" pin should be connected to "Vss". But you say in the video that you connected it to "Vdd". Maybe you were wrong. Thanks for the video. I already bought my board to experiment.
@usefulelectronics 2 ай бұрын
Hi Please Check out the sensor datasheet. If you connect the mode pin to Vss you can’t read the sensor key status register or any other register. This makes connecting the sensor to an MCU meaningless

Wow this is very helpful - thank you! I have one question though - if I want to decrease the amount of current that the circuit "trips" at - do I need to decrease or increase the resistance of the 1k resistor? - also will the transistor still protect against short circuits, even though it doesn't isolate the power source? Thanks in advance!
