Hi,
This is my first time working away from Arduino.I am creating a simple CAN bus analyser using a STM32F105RBT6I have used parts of circuits from various evaluation boards.
But I am mainly concerned about the Power circuit. I want to be able to power from VIN or USB. Both are to be able to be powered at the same time.I have also seen similar circuits using a 8mhz or 25mhz so I am not sure which to use.The Image dialog on here doesn't seem to work on Safari or Chrome on Mac so please check out this post:http://electronics.stackexchange.com/questions/215097/is-this-stm32f-based-can-bus-circuit-ok #can-bus #stm32f105rbt6 #!stm322016-03-28 10:00 AM
Hi gould.terry,
If you still need some help to implement your STM32F105 based board, I recommend you to refer to AN2586: Getting started with STM32F10xxx hardware development.You find there more tips on how to design your hardware taking into accounts device characteristics.-Mayla-To give better visibility on the answered topics, please click on Accept as Solution on the reply which solved your issue or answered your question.
