Re: F405 & F411 versions of the BluePill

Are you sure the clocks are running Ok?

I think perhaps STLink can upload even if the clock is not running

Re: Lightpen

Download the latest version of my repo as it now has the hardware Input Capture feature working Thanks to @ stevestrong... Look in the A_STM32_Examples under Sensors, Input PWM This uses the hardware Timer to measure pulse width. I presume you need to wait for a Vsync pulse, of specific length, then...

Re: Bluepill, PB10 and PB11 pulling down the signal while using as input

Steve If they selected the wrong board e.g. STM32F103V, It would compile and be possible to upload a binary But I don’t know what the result would be.. The pin is also defined as I2C2, SCL2, so potentially there could be an issue with the Wire config. However it’s odd that no one else has noticed th...

Re: Bluepill, PB10 and PB11 pulling down the signal while using as input

Not sure if this is why, but PB10 is USART3 TX Page 30 of http://www.st.com/content/ccc/resource/technical/document/datasheet/33/d4/6f/1d/df/0b/4c/6d/CD00161566.pdf/files/CD00161566.pdf/jcr:content/translations/en.CD00161566.pdf But this is not available on the Blue Pill What board did you select ?

Re: jfitter: STM32 on the Sunshine Coast

@jfitter The Arduino_STM32 codebase is a long story. There is info here about where the original codebase came from, https://github.com/rogerclarkmelbourne/Arduino_STM32/wiki/Credits-and-history However, I did a lot of the major initial work, to bring the old style "Arduino 22" (pre 1.0) codebase up...

Re: F405 & F411 versions of the BluePill

My misunderstanding

I thought the problem was related to one of the things Andy suggested.

Re: Timer "Input Capture" ?

OK.

I've pushed the updated files from @stevestrong, which work correctly for Input Capture and OnePulse
