Re: About the CAN controller.
Rudi: That would be the choice of the author of that driver. If he wants, he can file a pull request in the esp-idf github and we'll check the code quality and such and if that's OK, we will integrate it into esp-idf. If he prefers to have the driver as a separate component, that is fine too.

sry for confusion,Hans Dorn wrote:I know the theoretical throughput
At 1MBit you should be able to push out a little less than 8000 frames per second.
Did you really see 20 - 50 ms between frames, or are these µs?
Still a lot, considering a fast frame is only a bit more than 100µs...
Cheers
Hans
here in a test, that i can see the messages on receiver side with printf,
i have a delay in code between next send, sure you can have lees value of delay in the "house-can-bus or openCAN end firmware :
Code: Select all
void task_CAN_TX(void* pvParameters) {
CAN_frame_t __TX_frame;
uint32_t counter = 0;
__TX_frame.MsgID = 0x264;
__TX_frame.DLC = 8;
__TX_frame.data.u8[0] = 'E';
__TX_frame.data.u8[1] = 'S';
__TX_frame.data.u8[2] = 'P';
__TX_frame.data.u8[3] = '-';
__TX_frame.data.u8[4] = 'C';
__TX_frame.data.u8[5] = 'A';
__TX_frame.data.u8[6] = 'N';
__TX_frame.data.u8[7] = counter;
while(1) {
__TX_frame.data.u8[7] = counter;
CAN_write_frame(&__TX_frame);
vTaskDelay( 50 / portTICK_PERIOD_MS); // to see ( printf on receiver side ) what happend..
counter++;
if (counter >= 256) counter = 0;
}
}

Re: About the CAN controller.
no problem with the author jeroen, he did pleased me too comments and make it ready for the structure of ESP-IDF as driver so that we can add according to guidelines. with little changes and menuconfig gaves the CAN Driver at last the finnish and is now ready,ESP_Sprite wrote:Rudi: That would be the choice of the author of that driver.

as Driver in ESP-IDF or/and third party and a example code is ready too.
..
i do next time create a repo for this, upload it for people how wants use it yet with menuconfig,
i do then make a PR to the author repo as "third party", then the author can make a PR to ESP-IDF repo or "third party"
why this a little confuse is, the author willl have no access to a computer for the next weeks....nothing creepy
and i can not add Contributor License Agreement things in order of espressif.. cause have not the legal capacity to create contracts in Espressifs name.
so the author then can confirm later itself Contributor License Agreement if he makes the PR.

Re: About the CAN controller.
Hi there,
I tried to compile the previously named CAN example
I get an error like this:
...
/ESP32-CAN/main///main.c:102:1: fatal error: opening dependency file //main.d: Permission denied
...
Is there further configuration of the source file needed?
Best regards
DL88AI88

if you work in a VM which os you use as host and which os you use as gast?
if you in a OS, in which os you work?

No vm.
Just Ubuntu Linux 16.10.
All other examples are being built without issues.

Re: About the CAN controller.
OK, I solved it like this:
in component.mk I changed
COMPONENT_ADD_INCLUDEDIRS := / drv/CAN/include
COMPONENT_SRCDIRS := / drv/CAN drv/CAN/cfg
to
COMPONENT_ADD_INCLUDEDIRS := . drv/CAN/include
COMPONENT_SRCDIRS := . drv/CAN drv/CAN/cfg
Now it compiles.
