I have a STM32F303 connected to a L9616 as displayed below. The pullup resistor R3 is not present any more. Please ignore it. Vdd is 3.3V but, as can be seen, I have set Vs to 5V, believing that was necessary to make the CAN BUS work. With an osci...

Posted on March 09, 2016 at 05:26Hi. I have connected an L3G4200D to an ATMEGA328P via SPI.WHO_AM_I gives me 211d, or 0xD3, which is the expected value.The values I use for control registers are:CTRL_REG1: 0b00001111CTRL_REG2: 0x80CTRL_REG3: 0x00CTR...

Hello @SofLit,Substituting the L9616 for the MCP2561 solved the reception problem. The 8 byte sequence sent by one module is received correctly by the other module. Also, the transmission and reception callbacks are being fired, which is much much be...

Thanks for all the information! I'll measure the exact bitrate to be sure about it.The oscillator I'm using is an Abracon SMD.

Probably that will help a lot to improve the communication between the modules.

I have an external 16MHz crystal. Maybe that is why the HSE bypass is configured. I sincerely cannot answer your question with certainty.About the bitrate, how can I measure the real one? I thought the oscilloscope image would give some hint on that....

I took a picture of the scope:About the system clock, there is no important reason to be running at low speed. I came from AVR and just did not want to hit hard the accelerator. Increasing to full speed is in the future plans. Should I run it at full...

STM32F303 and L9616 CAN transceiver

Which guidelines should I follow to write C++ code for STM32? (please do not evangelise me on not using C++ on micro controllers)

STM32F303xx UART not starting, why? Answer provided.

L3G4200D giving constant values for x, y and z.
