Loved the I2C video and surveillance the SPI is equally as good. Your teaching method is really good. Got this in one view. Struggled with other books and articles so thank you for such an easy to understand video.
Hello Malcolm Hodgsom, I am very happy to know that these videos are serving the purpose for which i made. Initially i too faced issue to understand these concepts. Thanks for the feedback.
Amazing Explanation. I have a query on this topic. In SPI there is no Acknowledgement bit. Can you please elaborate on this. Specifically does it mean that our micro-controller (Raspberry Pi) wont be able to receive data at fixed sampling from the ADC (Ex. ADS1015)?
The explanation was beautifully explained. I just had one quick question about the clock signals. Would the data from the slave device transfer to the master while it is in the active state or only when the signal goes from 0 to 1 or from 1 to 0? I am sort of new at digital electronics.
Can you please check mode-2 and mode-3 , i refferd some documents & videos it will there like.... Mode-0 --->data sampled at leading edge(Cool -0 , Cpha -0) Mode-1 --->data sampled at tralling edge(Cpol -0 , Cpha -1) Mode-2 --->data sampled at tralling edge(Cool -1 , Cpha -0) Mode-3 --->data sampled at leading edge(Cool -1 , Cpha -1).
Thank you for good explanation. It helped me to start but there is a mistake with the MODE 0 example at minute 5:41. There is figured the MODE 2 but not the MODE 0. For the MODE 0, the data should be updated (changed) on the rising edge and should be sampled (latched) by the receiver on the falling edge. Please comment here if I am wrong or consider to correct this video if possible. Thank you!
Please help. I have TFT with built-in SD Card reader. TFT pins are like this: Vcc,Gnd, Gnd, Ncc,Ncc,Ncc, CLK, SDA,RS, RST and CS. SD pins are like this: SD_CS, SD_MOSI, SD_SCK, and SD_MISO. My screen works fine. But once I connect wire to share pins like CLK and SCK to have both TFT and SD card reader work together, I get nothing. Screen just show white background and serial monitor doesn't show any information about SD card. I also try to use SD card with standalone configuration by remove all wires from TFT pins and just connect sd pin to Arduino. Again, nothing works except error message about SD not being initialized.

Hi Sunil, No need to get confuse between RS232 and UART. Check the below link it will clear all your doubts: electronics.stackexchange.com/questions/110478/difference-between-uart-and-rs-232 I had already uploaded 2 videos on UART communication on my channel. you can find them under videos section. I know very less about USB communication so cant help you out as of now.
but how ?????? for ex. DHT 11 or many other sensors have 3 pins only vcc gnd output how can we communicate them with the SPI using clock then???????????????????????????
Hi Abhijeet, There are many suppliers in market no need to learn all of them. As soon as your project changes you might have to work on different controller. So from this video series I have tried to give a general idea that how to read data sheet and find out the relevant SFRs. Hope it helps..
Al the videos I've seen on this topic cover the same information, you are not and they are not showing how the connection is made to the hardware to se the SPI pull.
