Dear JorgeMaker
Hi,I'm student studying about can protocols and embedded programmings.
Now I'm trying to follow your works for studying
While carry on, I have few questions.
Now I'm using stm32 F407VGT6, (dev board name STM32f407G-DISC1), I modified some fw codes to upload on board.
I'm trying to get some can packets from another device through jumper cables. (actually it connected with Rapi CAN HAT).
But I find out I cannot get any datas.
1.While trouble shooting, I wonder why USB serial use 500000baudrate, (It seems to be unusual value).
2.My ttl to usb modules using 12000 crystal, Do I have to change bitrate for serial communication?
3.I tried putty, minicom, Windows, MacOS, hercules_3-2-8. Every programs were able to make connection with board through USB, serial. But non of them succeed to get complete datas like readable strings or HEX value. Is there any reason?
4.Do you have any other advice for students trying to follow your works?
5. I find out RTOS version fw(F407vgt6) while(1)loop is empty. NOT as non-RTOS version ( f103 version fw has some condition it it's own loop). Do I have to write some more in while loop to operate RTOS version fw?
Looking forward to hearing from you soon. best regard.
