Re: Touch GUI for the official Pyboard display

Great, 16 buttons would be more than enough, thanks :-) It's just too bad that micropython hardware is so expensive compared to the Arduino/Pi ecosystems... Just take measurements from PyBoard/screen, learn basic FreeCAD stuff, model your own case, order a production. Then tell us how much have you...

Re: AutoPilot

Added stupid version of a PID controller for speed/throttle. HERE it tries to maintain 600 kts speed.

Re: Showing jpeg file on LCD160

LCD160CR accepts raw jpeg encoded files up to a certain size (~65000 bytes). Only very basic parameters of the jpeg stream are evaluated. No EXIF decorators are accepted! It is a good idea to strip the jpeg files used with something like: jpegtran test.jpg > test_stripped.jpg For the example @pytho...

Re: RTC oddity: has anyone seen this?

hmmmm... I've started to get delays again... even with this code:

Code: Select all

from pyb import RTC
rtc = RTC()
rtc.datetime([2017, 2, 17, 1, 22, 28, 10, 0])
rtc.datetime([2017, 2, 17, 1, 22, 28, 10, 0])


and then it works fine after hard reset... still unable to catch the reason

SPI and DMA

I've found this code status = HAL_SPI_Transmit_DMA(self->spi, (uint8_t*)src, len); if (status == HAL_OK) { status = spi_wait_dma_finished(self->spi, timeout); } What is the purpose in DMA if we are still placing CPU on pause until job is done? :roll: Is there any way to get this done async?
