Thank you for all!

Could you make a video about the RGB protocol for the display? It would be nice to have a tutorial on how make your own HMI module using an high end mcu. For reference take a look at the nextion screens, creating something like that. If you are interested on making such a video i think that would be nice, there are no much tutorial about it. Bye bye. Ps. Nice video, you are great!

can you make a video about changing the input of a STM32 microcontroller from 3.3-5v to 24 v according to industry standards. What components have been changed?? Please

Why is this driver so slow compared to Timer and DMA? How could i achieve faster changes of the Pixel?

Ive tried this on atsamd20g18 microcontroller with 4mhz 5bit logic. But the mosi pin idle high. So it's not worked. Ive changed cpha to 1 but still getting idle high. But on atmega32p cpha changes to idle low. Do you know how to fix this in atsam?.

Hello, do you have videos on fingerprint (R305 or AS608) or could I make some with the stm32, since there are none on the network?. please

Hi I'm able to generate PWM like signals using SPI but the problem is that the time period of one cycle of the individual wave is 2.792μS instead of the usual 1.2μS, can you help me how to fix this?

Seems like you messed up the clock configuration for your mcu. Make sure you input the correct crystal frequrncy in the cubemx.

Hi, thanks for your reply I followed everything as per your video to get baud rate of 2.5MBits/sec in the Blue Pill What I observed that the duration of ON time for 1 code and 0 code is correct. The problem occured because in SPI, even if I'm trying to transmit only 3 bits of data, SPI still takes 8 bits and assigns unused bits as 0 and as a result 0b110 was literally 0b1100000
