I'm sorry if my question was not clear enough, my question is how to calculate CRC
As I'm trying to learn calculating CRC, first I reach at a point when I can give it a try calculating CRC then code and effort will involve
Thanks for sharing some information that I can explore wikipedia and...
I'm reading datasheet for nRF24L01 family module, please refer to link to open datasheet at page 28 (section 7.3.5 quited below) it tells calculating CRC that I could not understand.
For example sending text is 'Hello' how will I calculate CRC and what will be final CRC number I will get, (I...
Its my first time using internal weak pull ups I gone through some threads on this forum and I believe my understanding is good I can use internal weal pull up for buttons.
I have this small project to turn on relay after some delay, Problem is that when I use exrernal pull up resistors it...
But you are not using the formula as sown in the datasheet? is there some math rule am I missing? I wanted to learn what made you understand to modify the formula and its till valid, and why i was not able to calculate by following what is said in the datasheet
fRF = (XOSC) * Fr f / 2^19
I was reading datasheet for module RF96 (datasheet attached), by reading the datasheet I understand that we have to set register values to set carrier frequency as descrubed on the page 103, this topic is also described in some other sections of the datasheet like Pages, 13, 53, 77, 88
Formula...
Thanks guys, I will put further information, by saying that I want to know if I'm sending correct commands to initialize the sensor I meant rest of things like communication, timing, code etc I have checked and they look good, but I understand still you can get some cllue there. I will attach...
I'm writing code for PIC mcu to read sonsor BME280 through SPI (for some reason I can't use I2C) I read the datasheet and here is what I understand to read sensor.
To start onversion through Forced mode I send 0x74 which is ctrl_meas register address I send values 0x25 that means x1 oversample...
That must be sleep time current consumption?? I referred to current consumption while sending data
I want to read temperature, humidity from sensor HDC 1080, then send to MQTT server, for that I have TPL5110 (or may be using TPL5111) power gate timer that will trigger after each set interval...
Can you please refer to datasheet (i just uploaded) it will help me to understand what values i should consider while selecting mosfet.
I'm using TPS5110 timer to drive the mosfet, TPS5110 sends active low signal to turn on the ESP, that means before mosfet Si2365 i will be using an other N...
I'm looking for a MOSFET to turn on ESP12, but here i want to learn what parameters should i be looking for while selecting such Mosfet, for example
ESP12 consumes 200mA on avg, (there are spikes of about 450mA)
its a 3.3v device
based on above i found Si2365
I will be running ESP12 on...
What I quoted above in my question was from datasheet but i was not able to understand what they are trying to say,
It sounds me like it will turn ON the MOSFET and after a period of time it will turn OFF the MOSFET (one cycle) if i understand it true what if ESP was not able to connect and...
I was reading datasheet of TPL5110 it says "the TPL5110 has a unique One-shot feature where the timer will only power the MOSFET for one cycle."
I do not understand what does it mean by "One-shot feature" and "turning on MOSFET for one cycle" here what does it mean by powering up MOSFET for one...
I found this ESP32 Camera modules at aliexpress, it shown in the picture it says one module has logo AI on it but the other one has different logo, i wanted to buy some modules i and though if i buy wrong module by mistake,
can someone suggest if it matters? or if someone can suggest some...
Ahh found the issue, while writing reply to you i realized i used assignment operator instead of equal so i change isrInterrupt_A = 1 to isrInterrupt_A == 1 and it works, thanks,
What i expect from code, that when i press button that connects pin 2 to GND it should trigger the interrupt, that is because i pulled up pin 2 internally (thought i also tried external pull up) and i set pin 2 to trigger interrupt on falling edge that means when i push button to ground it...
