STM32 UART #7 || One-Wire Protocol || Interface DS18B20

[@SalmanShahid-j8k]

Hello Your Videos is clearly explained and i watched mostly i have a request can you please do a series on OV5640 camera interfacing with Local PC GUI or with TFT display

[@siddharthabajracharya7434]

im using an stm32l4 board and at where the value of the presence variable changes to 1 but LCB and MCB are not changing. what am i doing wrong here?

[@mieteksuchar6662]

Not related to UART, but how about creating a music tempo (BPM) detection algorithm?

[@jorgemaker4622]

It would be very interesting if you publish a video explaining how to sue the STM32 to implement LIN Bus communications that is acheived adding a LIN trasnceiver attached to the UART

[@ControllersTech]

Yes yes coming next.

Hi, this sensor use a “parasite power” this dosent mean that you have to use the Tx wire as a Vcc wire too?

[@ControllersTech]

No it doesn't

[@erenakcay7010]

hello,thank you for this video.I have to use more than one DS18B20 sensor.How can ı do it can you explain please

[@ControllersTech]

Search for "multiple ds18b20" on this channel.

You are the best

Hello and thank you for this video (and all the helpful other ones ;-) I managed it to run your example on a Nucelo-F429 => it works with one single issue: the interrupt doesn't work !? => instead of this I simply used a HAL_Delay(1) so far so god I also tried it with a Nucleo-H743 => the "presence" is recognised perfectly... ...the Write-Command also seems to work... ...but in the buffer-array of the Read-Command always bit "0" gets the value "0x00" (not 0xFF or 0xFC as it should be) and also the last bit is sometimes a "0" (by the way: my Logic-Analyzer (DS-View) shows the correct information = only 0xFF or 0xFC for all 8 bits) => so it seems that the STM32H7 reads the correct output signals from DS18B20 in a wrong way => ?? As I found out so far, it could be a problem with the content of the "USART_BRR register" ?? ...or the prescaler ( thanks very much

[@woldecosgrove]

ya i got the same problem too, i try on F072 nucleo board, my logic analyser show all 0xff... and on H723 same Oxff too...

[@woldecosgrove]

@ controllerTech could you advise...

Sooo... when can we expect DHT11/22 coverage? 😉 Just kidding, and well done, thank you!
