Hello,i have a cheap chinease mhs 3.5 type C clone display (it claims 180mhz on back). Your library works perfectly with it, the only other lib that i have gotten to work is the waveshare mhs lib but i use so infrequently i ccan never remember what i hhave to do to get it to work. Anyway your readme is the first clue as to why it doesnt work with the other libs. If i read it right they are using a serial(spi) to 16bit parallel shifter? After getting a small handful of tfts working on libopencm3 i got cocky and thought i ttry my ili9486-rpi working in libopencm3 as well..uhg pride before the fall. im using your init from the ili9486-rpi and sending everything 8bit just like what works on ili9341 etc. I tried to figure out the difference between the reg ili9486 vs the rpi version also the differences between rpi and ili9341 by reading your code but im just not that good. im not sure if some things maybe all things need to be sent 16bit, also i see strobe sends in the code and my basic knowledge of strobe is it requires a pin to be pulled high/low every other clock cycle and that cant be right cuz it seems the all pins already perform a function. Id be very appreciative for any insight on the differences/required changes. oh forgot my board has a single chip (the shift converter?) but the top, but was burnt off so no idea who makes it (readme made me think it coulda had multiples) Thank you for all the hardwork you have put into this lib i love it!
