Hello, i've been trying to get SPI working in conjunction in DMA.But with "bare metal register implementation" i can't even get the NSS working properly. The Stm32F730 needs to hold NSS/Chip Select high all the time, except for when communicating wit...

Hello, i am trying to interface TI's ADS8910 (18bit SAR ADC) to an STM32F730 via normal SPI, since i am unsure whether QSPI will work.I want to achieve the full 18 bit @1MSa, which is possible when working with 54MHz (/2 APB2 prescaler on the F730 wh...

I don't do everything bare-metal, only the time-critical parts. The rest of the code works fine as far as i can see it, i use a couple other interfaces, some stuff with HAL, some without (GPIO's generally without).The GPIO on the CS only doesn't work...

Thanks, i should definitely test that.So far I've only been thinking about how i can process each sample before the next arrives, so that handling the raw data works in "real-time" and once i've stored a few hundred processed samples, i'd transfer th...

thanks for the quick answer!I would like to, but i am unsure i can do it for the SPI to Memory part, the SPI on the F730 has only 1x 32bit FIFO each (one for RX and one for TX) and i need to clock and receive 22bits per sample. So i can't even buffer...

Is there any chance that this functionality will get added in the near future?
