    … Yes. Visual Micro have registered with this forum, and they provide good support for Stm32
  2. "bit bang" SPI pins STM32F1

    racemaniac

    …ll. So if you choose to use spi on your 3d printer board on pins not supported by the stm32 hardware, you can indeed resort to bitbanging it to other pins. And from that point on, it doesn’t matter whether you still keep most pins of the SPI port of the stm32,…
  3. $10 O-Scope revisited

    … but ground return path and common power supply for analog/digital combined with poor STM32 ADC PSRR performance (I have seen figures as low as 20 dB, but can’t get my hands on it right now). Of course, we could go 4-layer with separate analog LDO just to be s…

    It turned out that it was no bug in the software, the CS and CD pins were set correctly in another macro in line 187. Due to not correspondingly working PB2 some coordinates and colors can be wrong, but you should be able to see something on the display. Do yo…

  6. 32-bit timers

    dannyf

    on many STM32 chips, certain timers can act as both master and slaves. As such, it is possible to chain more than 2 timers together to form 48bit composite timers (3 x 16-bit timers), or 64bit composite timers (4 x 16-bit timers). or even more. Not sure of the…

    The sound level is OK, just that the camera mic could not reproduce it appropriately. Anyway, I forgot to mention that the sw I posted needs this patch: https://github.com/stevstrong/Arduino_S … 77705acec9 This clears the IRQ flag before enabling the respectiv…

    …’t have the time. As a side note, the bit-shifting pixel functions are quicker on the STM32 than the lookup tables, so if you revert those, you can get a bit more performance. Waste of time, IMO. This is why many (most) commercial endeavors shun (reject, avoid…

    Micheal On the BMP you have to wire its serial Tx and Rx pins to the STM32 PA9 and PA10 ( USART 1) Note. I cant recall if Tx or Rx connects to PA9, but its well documented elsewhere
