Give the STM32F470 chip, access to 3 high-speed serial ports at the same time, each channel, each frame of data is 200 bytes, 100hz update rate. There will be data loss, this problem cannot be solved. Here to ask thank

I think that lost something in translation..

Define high speed.

Should be possible to deal with 3 concurrent serial streams at 460800 baud using DMA on an STM32F4 platform. I'd hazard it could go significantly higher.

I personally wouldn't use HAL to do this, but to each their own..

thanks，I try it
