Course Description :
====================================================
Mastering microcontroller : TIMERS,PWM,CAN,RTC,LOW POWER,STM32 Cube HAL APIs

This is course is highly recommended if you are seeking a career in the field of embedded systems and we have carefully crafted all these lectures with hands-on programming exercises, debugging tips and step by step guidance.

You will understand TIMERS, CAN, PWM, RTC, and LOW POWER working principles from ground level and code them using STM32 Device HAL APIs provided by ST.

Some of the highlights of the course are,

1. Understanding STM32 device HAL framework, ISRs, callbacks, and peripheral handle structures.

2. Internals of timers: basic and general purpose timers

3. Timers input capture and output compare unit and programming

4. PWM Programming

5. CAN fundamentals

6. CAN Frame formats, bus arbitration, bus signaling, transceiver and other important CAN details

7. STM32 bxCAN peripheral architecture and can filtering mechanism

8. Programming STM32 bxCAN peripheral

9. CAN protocol debugging and understanding CAN traffic.

10. Lower power modes of STM32: SLEEP/STOP/STANDBY and wake-up procedures and current measurements

11. Usage of WFI, WFE, SLEEPONEXIT feature of ARM Cortex Mx processor

12. RTC programming: calendar, Alarm, Wake-up timer unit, timestamp unit

13. RTC and low power modes

14. Eclipse based OpenSTM32 System workbench is used throughout the course to develop applications . The IDE supports windows/mac/Linux machines.

Hi, Thanks for your helpful tutorial. But is it possible that you have miss one step in your description. I miss the HAL_CAN Start().
After this, it also works for me.
Thank you...

Hi at 8:43 minute mark you seem to skip a section on configuring the bxCAN modes. I have stepped through my code and things seem ready to transmit but they don't and I'm assuming it's because of the missing bxCAN mode configuration.
The video also glitches showing the CAN modes state diagram at 8:43, could you add this video? I would really appreciate it. These have been great lessons. I think Danial Jung is commenting on the same thing.

Is that header prototype a CAN standart?

Hello!!!Please, give me a hint. I want to transmit message via CAN2, the same message perfectly is transmitted via CAN1, but when I add CAN2 to transmit the similar message, it is not transmitted. I use STM32F407 Discovery board.

And also in tx messagepending function it had 32 bit return value why I mean it returning 0 or 1 then why we need 32bit thier

Hi, i have a STM32F401RE, it is work with canbus or i need to expansion board?

[jasonjoon]

How do you send a message more than 8 bytes?

[stewartchristian]

How can you pass a pointer thats not assigned to an address?

[alessandropicco]

CAN1_Tx defined but not used....what Is wrong?

[rajeshmendem]

Why txmailbox was 32 bit even though we had only 3 mailboxes can anyone explain ?
