Re: Espressiv API without FreeRTOS

I apologize if I keep using this post to talk about a problem that is not the initial topic. I don't really know the rules of this forum and why I'm not allowed to create a specific post about my question. I'm developing a product that reads the R channel from a VGA interface and it doesn't matter t...

Re: Espressiv API without FreeRTOS

Wow! Thanks! That was quite a help! I tried to find something with I2S, but I didn't find anything about doing 1-bit reading. What I found was always dedicated to capturing audio and analog signals, for this reason, they didn't achieve the sampling between 5 and 10MHz that I need. Could you indicate...

Re: Espressiv API without FreeRTOS

Hello, If it's not possible to use without Freertos, is there any way to suspend interrupts for 30us? I'm doing pin readings that need high frequency. void IRAM_ATTR sync_horizontal() { noInterrupts(); if ( vsync_line>2 && vsync_line<7 ) { for ( pos_array=0; pos_array<160; pos_array++ ) { mem[lyne_h...
