Arm Development #2 - STM32 Cortex-M0 I2C Tutorial using ADS1115 Analog to Digital IC - Keil & CubeMX

[@chrisw3260]

Coming from the nice and easy arduino world, your video helped me tremendously to get the i2c connection for my camera module set up, thanks!

Really enjoying the new ARM development series. Also having a forum on the website's a great idea.

[@VladRomanov89]

Thank you sir. I believe a forum is definitely the way to go. I know that there are many of them out there, but it gives me a much easier way to answer some of the questions I keep getting. Not only is it easier to upload images, files, etc, but it also allows others to see the questions, comment and for me to be able to point people back at an answer if it has been addressed already. Cheers, Vlad

Great video. Very clear step by step and clear reference to data sheet. Thanks!

[@tomr3072]

Great video thank you so much! Really helped me to understand the concept of the registers, for using the ADS1115 with Matlab :)

This video helped a lot. Thank you!

When computing "reading" you do ADwrite [0]

Hi, nice video! I'd like to suggest a correction. @12:00 you divided the full scale voltage by 2^16. It should be divided instead by 32767 (=2^16 -1), which is the maximum value of a 15 bit number. The difference is small with such high resolution, but you loose 1 lsb of accuracy.

[@cmuller1441]

He divided by 2^15=32768 not by 65536. He is correct.

Why are you overwriting the same variable for transmitting? Can't we use different ?

Hey. I'm new with STM32. I'm coming from PIC microcontroller with Mikroc compiler. I want you ask a question. I have a IC called BU94603 that when you send command to ask the name of music is playing, it will return by I2C the name. Each 8 bits repesent a charcter name of the song. By while I was watching your video, I saw that you need to specify how many bytes you gonna receive by I2C when you use I2C_Read library command. But I don't know how many bytes the microcontroller gonna receive from BU94603. It depends how much long the name is. So, any suggestion ?

const float line 65 should be 6.144 and not 6.114

Great!

dont use 4 channels , use them as 2 differential pairs as it rejects noise and can directly be applied to industrial commercial product. ADS1115 has everything oscillator voltage reference Power on reset but its poor at ESD only +-2KV......so be careful.....also when u reduce Full span to get more accuracy , the input impedence drops very bad , so a chopper opamp voltage follower must be employed..
