Re: Bring back the LIN components

Had a poke about for LIN Master ICs during tea break, NXP SJA1124 Quad LIN Master Transceiver looks interesting, same way as with CAN, writing a whole protocol engine is a big job, maybe an external LIN Controller IC is the way forward. https://www.mouser.co.uk/Search/Refine?Ntk=P_MarCom&Ntt=155...

Re: Bring back the LIN components

Sorry to bump this old topic. Was there any progress with LIN and PICs ? I appreciate its no small task to get a fully working FC protocol. I've just been given a door lock and expect some HVAC vents for a low volume automotive project. Not critical but seemed a sensbile time to look at LIN options....

Hi, I get on well with the ECIO28P & ECIO40P but Hardware i2C, UART and SPI channels share some pins. I know I could use the software (bit bang) version for some applications but where possible I've traditionally used the hardware output. A) am I just making my life hard by trying to always use ...

Re: RPI and long distance radio

That is indeed interesting...

Re: RPI and long distance radio

Hi, Yes I was also a bit disappointed with the gamma... in wide open space it was much better. The LoRa Lambda module was much much better... the time to react to the siganls (send/recieve) is a couple of seconds but the range is much farther. For triggering relays, you can just use the normal Input...

Re: RPI and long distance radio

Hi Abhijit, For long range I used the Lambda module which is LoRa based. I have used the Gamma but only achieved around 100m in our wooded environment (no where near the claimed max distance ), you would get much more in wide open space I expect. Check the version you have as some are 3.3V and some ...

Agreed, it was not too hard (ish! :) )to get a simple flowcode setup to send SMS over GSM. You may want to drop your update rate but it does give you almost any range you want.
