If the MCP2551 VDD is 4.5-.5V then it shouldn't be connected to the NEO without a series resistor on the CRX pin. Its easier to use a 3.3v CAN...
Finally tested with these transceivers and everything seems to work. I brought up both the can interfaces (can0 + can1) and connected a...
I would be very cautious if plan to expose your NEO for internet access without first hardening the platform/os and creating some kind of DMZ or...
The kernel source is here and instructions for building a kernel are here .
The changes I made aren't really to do with the M4, they are to do with hogging pins in the dts which can't make sense if they want to be...
If you want to capture jpeg (or h264) have tried using a usb camera which output jpeg?
If your after device memory maps they are described the imx6sx reference manual which can found here.
Given the encoding frame rates your seeing ~3fps with ffmpeg/libav then your not your going to encode the VADC output to h264, a point I...
It is covered in this post, last response (seems to be 4 years).
Great, that you've made more progress! Regarding transceivers, these are pretty cheap although shipping can be slow.
I2C_3 isn't available because its internally connect to the hdmi controller and not exposed externally. The remaining 2 ports may not be...
The internal ROM can't be modified that is why is called ROM. A suggestion, to partially speed it up, why don't you include the M4 image inside...
No you can't cross over TX/RX its not that simple. There is a application note (from siemens) which attempts to do this via diodes, I haven't...
I have created a separate post with instructions on how to enable flexcan, you can use that as a starting point.
Here are instructions those of you wanting to enable and verify flexcan support: 1. Firstly one or both of the flexcan interfaces needs to be...
Thanks for testing it! Regarding encoding, this example should give you an idea of how to encode. You need to change the PXP output format so...
The NEO does support CAN (it has an on board controller) and like most modern day cpu/mcu's the I/O pins are only 3.3v tolerant (same as rpi). So...
Although I haven't managed to get hold of one yet and I can't confirm it works, you can try using a SN65HVD230 like this board . I mentioned...
If your attempting to interface to an industrial engine, then there 2 (or may be 3) parts to solve, 1. Getting the CAN drivers working on the...
To enable Flex CAN you need to enable the one or both of the can controllers in the dts file, this should also assign the external pins correctly...
Separate names with a comma.
