I'm looking for wireless device which can send the log data to my PC. distance between PC and device will be around 3km.
I have search few devices and I found that LoRa will be suitable for my requirement but not sure how much speed i will get at this distance?
I'm planning to use...
When i was creating a footprint i found that footprint create from PCB library expert and Altium IPC Complaint Footprint Wizard does not match. if both follows the same standard then it should give the same result.
After that i have investigate the issue and i found that in Altium designer Toe...
How to port MQTT to any microcontroller?
I download MQTT code from Github but din't understand how to use it for different microcontroller such as NXP,TI,ESP8266...etc
Any body know how to get started with MQTT porting from embedded paho source code?
I got easy design from ST TDA2822 but only problem is TDA2822 original chip from ST is not available easily from local supplier. Chinese supplier has cheap TDA2822 but not have idea whether it will work stable or not
Any one has idea about TDA2822 chinese IC performance and stability??
Basically I'm using DRA818 module for walkie talkie application.
In this module squelch level are configurable from 1 - 8 level and 0 - is for continuous scan mode.
If I set 1 - 8 squelch level then during audio reception voice is breaking in between and it is not working properly but the same...
1) I'd implemented the circuit but couldn't get the required output.
MPF103 and audio amplifier section not implemented as in my circuit i'm using LM4871 for amplification.
I'd just monitored the voltage at 560K resistor and collector pin at Q1 but output remain same in both cases when signal...
I want to write data into internal flash where code is being executed. When i perform write operation on flash at that time i can not read or execute from flash so in this case i have to copy flash related code into RAM.
using __attribute__(("section name")) command I'd successfully...
Thanks for you kind support
Can I use SMD inductor instead of coil type??
My Transmit frequency is 150MHz and received frequency is 155MHz can you please help me to design low pass filter for this frequency.
Basically I'm looking for filter for antenna for frequency (150 to 155 MHz). I'd google it and got some result but i don't know how to made such type of inductors.
In image if you see there is a specification 2ov/@6mm what it is??
can I put standard inductor instead of coil type inductor...
