I landed here with the intention to add and tune rc filters to analog input signals similar to the author of this thread. What i ended up now is using a software filter solution based on the 1euro filter algorithm. It takes only two parameters to tune, which was quickly done in case of my...

awesome thread, thanks! i'll keep reading for now.

thanks for the hint

Hi mjs513, thanks for the answer. I might try direct port access on T4.0 in a similar way to T3.6. I found detailed pin information here: https://forum.pjrc.com/threads/54711-Teensy-4-0-First-Beta-Test?p=207775&viewfull=1#post207775 Seems like there might not be 16 pins from the same port...

this might be the corresponding library from nxp: https://mcuxpresso.nxp.com/api_doc/dev/329/group__lpc__lcdc.html

Hello Forum, i want to explore the possibilities of driving 16bit parallel LCDs hardware accelerated with Teensy 4.0. I found nothing directly related on the forum. Please let me know, if i missed it. First of all, thanks Paul Stoffregen for this beautiful new piece of hardware! Reading this...

i am interested on what the critical load on the ISR roughly is, given a specific baudrate. there will be several factors influencing this for sure, but i might do some simple tests just to get an idea.

was thinking the same at first. but it seems to work like this.

for the 1 byte functionality: edit the UartEvent.h you will find this piece of code, where you can shrink individual rx buffers to 1 byte: //////////////////////////////////////////////////////////////// // Tunable parameters (relatively safe to edit these numbers)...

hello duff, thank you so much. i did a couple quick tests that worked very well and will soon continue on that project. thanks again!

could it be overload? i tried 125kBauds instead of 250. now i get one led toggle once when the transmitter starts sending and once when it stops sending. the transmitter only supports 125k and 250k unfortunately.

thank you. here comes my test code. the led blinks with rx buffer size = 2 or higher. but nothing happens with rx buffer size = 1. test setup: the external device which sends the serial generates a lot of 0x3E bytes. ( it generates packets where 0x3e belongs to the header. unfortunately it does...

it is version 6

single byte event Hello Duff, first of all, the UartEvent lib is exactly what i was looking for, thank you so much. i played around with the examples and i may be blind, but there is one thing i am not sure about. how do i listen to a single byte event? i tried to shrink the rx buffer size in...
