Thanks for recommending this library it seems to work great for my setup (all the items i've tried are a couple of grams out ). so it does look like the library i was using didn't work correctly with the teensy. now just a case of getting the value on the nextion display.

Hi Everyone I'm looking to build a Car display Gauge using a DWIN Display and a teensy 4.0 I've kind of figured out how to send and receive the can messages from the OBD port. Then figured out that the display needed a solder bridge to actually send and receive serial data. What i'm...

i would like to avoid it moving tbh to minimise the risk of it possibly tipping over and it would start to get a bit big with the size of the collection jar (4-5l demijohn)

what library do you use for the interface to the hx711 ? yeah ideally i would of prefered to use something with a 0-10kg range but all i could fine was a single bar load cell that would of been difficult to setup up and not collapse with the 5kg load on it

they were screwed in the corners to a piece of mdf (about 200mm/8in square) in some 3d printed frames to allow them to move when a load is applied. I made sure they were connected in the correct order according to a few places on the net.Like here i tried to move the weight about on it and it...

yeah i did think i may have broken one of the load cells (comes as a set of 4 ) like this thats why i ordered another 3 sets (hx711 pcb and 4 50kg loads cells) but they all act the same. I was thinking it maybe something to do with the way the teensy reads the value with it going negative with...

Hi I'm trying to build a controller to semi-automate a still to distill "water". I'm going to be using a teensy 4.0 some ds18b20 temp sensors, and a nextion display. I've got it to a point where i can see all the temps on the display and control the outputs etc. But i want to add a scales...

If i was to fuse the the Read CAN data (This would be unique per teensy) to the fuse memory, i guess that it could not be Re-programmed if it was to be re-used to read different CAN data? (the output data is always the same) i.e Only run code once can id 0x415 msg.buf[0] = 0x50 & msg.buf[7] =...

I'm looking to make an item to Transmit some CAN data but not until it reads certain CAN data. But when programming each teensy the sketch will be altered to suit the read data. So will i be able to use the same Encryption key for every teensy even though the sketch changes? I'd like to be...

hi all I've been messing about with CAN bus data on and off for a while now and have got my head around how it works so to speak. I used a car speedo cluster to see if i can get it to do any thing and how got some functionality out of it (speedo is from a Vw polo 6c) now i've logged a load of...

Thanks That worked a treat. I'm sure the code only output the number of bytes in the can frame and doesn't pad to the full 8 bytes (the can frame it is receiving is from a teensy 4.1 and that is the correct Can ID to keep the vw PQ26 dash clocks i'm playing with awake and it does have the full...

Has anyone managed to get SavvyCan to work with a Teensy 4.0? i've have got it to sort of reading serial data but the Teensy is outputting ASCII and SavvyCan is converting it to HEX and thinking its just junk data. (i'm not sure of a way to output HEX rather than ASCII) so i'm looking to...

i made this using some parts off LCSC and a pcb i designed the connector on the teensy is Part No C264990 the sd card holder is C114218 and the flat flex is 100mm (any longer doesn't work for me) is C45200

the nano code is sending the same frame all the time so that's where the confusion was happening. having tried with the old transceiver on the receiving teensy, if i unplug the USB power to the nano the teensy starts displaying the same frame on serial with a time of between 0 and 1 between...

so i just tried the sketches tonton81 posted in #302 with my new Transceivers and it looks like they are working. this is using a 4.1 to receive and a 4.0 to send and a nano to send (4.0 ID 0x740 and nano ID 0x608) MB 99 OVERRUN: 0 LEN: 8 EXT: 0 RTR: 0 TS: 59889 ID: 608 Buffer: 4F 87 32 FA...

i connected the Rs pin to ground according to the datasheet (did this mod on the 230 boards) but according to the datasheet the loopback pin can be left as it is internally pulled to ground and needs to be pulled high to enable loopback mode

has any one tried the SN65HVD233DR transceivers before? as i read back on this thread and saw that someone had problems with the transceivers i was using SN65HVD230 chips. so i just swaped them over and the new ones are working but seem to be very slow. with the old chips i'm seeing values of...

just some basic stuff to start with would be good to try and get a bit more of an understanding (things like engine rpm ,coolant temp, vehicle speed) i've kinda got the grasp that there are two versions that seem to appear on cars (message IDs can be 11bit and 29 bit) and the data length is...

so after trying the transceiver connected to a car and printing data to an sd card it seems to work. now using the can data is where it looks like the learning curve goes vertical :confused::D

I'm glad i found this, was thinking i had some sort of virus on my pc.

thanks tonton81, i tried that but I failed completely trying to work out where to add that to some example code. i think I've got them working using an arduino nano and and mcp2515 as a transmitter and i got this serial output on the teensy 4.0 using the beta_sample example This was the...

hello everyone. I'm am fairly new to micro controllers so don't have much knowledge of them (have dabbled with some arduino nano as temp controllers and neo pixel drivers) i'm looking to build a display/data logger for my car (2015 VW). i've got got 2 teensy' (4.0 and 4.1), 2 SN65HVD230...
