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?

Re: USB_VCP buffer

Ok, my double fault. First is that I'm sending "lines" without line endings, while reading them with "readline()". So I'm getting all 3 at once. Then happens second fault - code unable to handle so many parts from such big string explosion by comma.
Thanks for info )

USB_VCP buffer

I'm sending data to PyBoard from my laptop via USB. As you can see - I have to sleep() on each send, otherwise PyBoard blinks with green and red LEDs and just hangs its work. Here is the receiver part . I would agree to sleep() once per while-loop iteration, not per line being sent. Is there any lim...
