STMP1 / Re: CAN controllers on STMP157...
Last post by LubOlimex - May 29, 2026, 10:58:42 AM- You can have HDMI and CAN but only in the STMP157-OLinuXino-LIME2H, STMP157-OLinuXino-LIME2H-EXT, STMP157-OLinuXino-LIME2H-SB variants of the board have HDMI (e.g. base STMP157-OLinuXino-LIME2-EXT has no HDMI). The HDMI also fits in the box:
- Now I checked you can have both CANs and HDMI; of course for CAN2 you need to place own transceiver chip and everything else that it needs like resistors and capacitors and pull ups and so on (maybe simply copy what we've done for the CAN around the SIT1050T), but the wires are led out to the headers - USART3_RX wire is PB12/CAN2_RX available at GPIO-1; DFSDM1_CKOUT wire is PB13/CAN2_TX available at GPIO-3; DFSDM1_DATIN1 is PC3/CAN2_STBY again available at GPIO-3.
- The power input is 5V only. If you only have 12V DC consider driving it down to 5V DC, if you have no own converter consider one of these:

If 220V AC are available simple adapter like this one would do the job too:

STMP1 / Re: CAN controllers on STMP157...
Last post by dry - May 29, 2026, 05:58:13 AMThanks for reply @LubOlimex,
Does this mean the board variant with CAN connection has no HDMI? Is there variant with VGA?
Could you help in case I order: which options / or option of the board Does come with CAN transceiver and port? Just so I don't get it wrong.
But are the 2nd CAN controller lines routed to the GPIO-x connectors on your board? I _think_ I see it in schematics, but I don't want to make mistake.
Thanks for the box, it will do.
Can I ask you, is the supply input strict 5V? Won't work from 12V by any chance..? (Sorry for dumb question in advance)
Quote from: LubOlimex on May 28, 2026, 09:27:34 AMe side of the CAN controller (since the STMP board has no HDMI), check

Quote from: LubOlimex on May 28, 2026, 09:27:34 AMcan't say if in the OLinuXino board the second CAN is supported by the software (or if it can be enabled by the commands), but you can probably check the Linux configuration

STMP1 / Re: CAN controllers on STMP157...
Last post by LubOlimex - May 28, 2026, 09:27:34 AM- About the jumper, it is there for compatibility reasons. If we decide to put other CAN controller. It makes no sense to change it with the CAN controller that we currently use (since it is 5V only), but we have used controllers in the past that could work at 3.3V and 5V.
- About timestamping - the hardware combo supports timestamping, it comes from the STM32MP157 chip. Can't say if I tested if the software supports it but even if it doesn't it shouldn't be hard to get it working.
- About the box - we don't have a custom box, however, the STMP board fits in the LIME metal box. There is just some free space at the side of the CAN controller (since the STMP board has no HDMI), check the pictures for each side:
The box is this one:
https://www.olimex.com/Products/OLinuXino/BOXES/BOX-LIME/
- About the software, I know for sure that in both STMP157 designs the CAN connector is tested empirically so there is CAN support in our Linux image. I can't say if in the OLinuXino board the second CAN is supported by the software (or if it can be enabled by the commands), but you can probably check the Linux configuration for the BASE EVB board (which has two CAN connectors):

It is also good idea to take a look at this document about the Olimage Linux:

STMP1 / CAN controllers on STMP157-OLi...
Last post by dry - May 28, 2026, 06:07:50 AMHello Olimex, Interested in this board,
https://www.olimex.com/Products/OLinuXino/STMP1/STMP157-OLinuXino-LIME2/open-source-hardwarea
- The chip if I'm not mistaken has 2 x CAN FD on it, are the second CAN controller pins available to connect external transceiver through board's GPIO's blocks, and Linux driver(s) can use second controller? I need to connect own external transceiver(s). If it requires alt function or muxing, what would I loose if I want second CAN, considering the stack thats running on it?
- Could you confirm that both those CAN controllers and driver supports the hardware timestmaping of messages? (i.e., its not the host's own timestamp)
- Could you explain the purpose of this 5v/3v3 switch on CAN transceiver on board, doenst' that module only support 5v CAN?
Is there a box/housing available for the board, similar to how you have for A20 Micro?

Last post by olimex - May 26, 2026, 09:31:09 AMTuxCon 2026 is over, and once again it was an amazing weekend full of talks, friends, hardware, open source, and the traditional soldering workshop at Olimex.
Huge thanks to the volunteer organizers and to everyone who joined us — from the youngest 4.5-year-old participant to the experienced makers and hackers who keep the community growing every year.
See you all at TuxCon 2027!

ESP32 / Re: Olimex ESP32 POE
Last post by LubOlimex - May 25, 2026, 08:10:33 AMEach ESP32-POE is tested empirically after manufacturing. The test includes programming at least two times.
Double check cabling, port selection, programming settings and configuration. Try with another software tool.
Try reinstalling the CH340 driver.
My advice is to also first try with the tools supported by the chip manufacturer Espressif - like esptool, ESP-IDF, ESP32 package for Arduino IDE.

ESP32 / Re: ESP32-PoE-ISO UART1 issue
Last post by bartgrefte - May 24, 2026, 10:54:51 AMThen why does the MOD-RS485-ISO have a half-duplex mode which according to the manual is the default mode? It wasn't actually default by the way (neither was passthrough mode which required a factory reset), there was only one jumper on the board and it wasn't used for half-duplex mode.
Since it seems the MOD-RS485-ISO does not actually support half-duplex mode, why is this even in the manual and why are there jumpers for this?
Finally found the AMS1117's so that I could test the 3.3V FTDI-cable (with 5V VCC) directly on the MOD-RS485-ISO, without having the ESP32-PoE-ISO involved.
When connecting it to my laptop and testing with ModBus Poll (which I confirmed working with a RS485 USB stick) I got "insufficient bytes received" and when I checked the communication traffic the data looked the same as when I connected Rx and Tx together: what is received is the same as what was send. Is this to be expected?
Currently waiting for "dumb" RS485-UART adapters that are 3.3V compatible.
