Hi everyone. I just thought I'd share this result so that anyone else who is looking for a proven Teensy / RS485 combination operating at a fairly high baud would have this as a starting / comparison point. I'm using 2 x Teensy 3.5 (code is compiled with CPU speed of 144MHz - that's important...

@mjs513, by your comment "so let's give them a break on this" you seem to have taken a defensive stance on PJRC's behalf which makes me think you believe we're just sticking the boot into them. I'm most definitely not. As I stated before I'm incredibly grateful for everything in the ecosystem...

@FrankB, I'm sure we're both clear that it's not as simple as just opting out of buying the new board but I'll play along. PJRC are a very small team and if they devote resources to the development of a new board then they will have less resources to work on fleshing out their existing...

Hi tonton81, note I said I consider 600MHz to be overkill for all use cases that I'd consider doing with an MCU - I acknowledged that other people will have different use cases but my main point was asking the questions: what percentage of users need 600MHz and would the majority of Teensy...

I'm with the likes of jwatte and epyon in thinking that an MCU of 600MHz seems like overkill for all use cases I'd ever consider using an MCU for. I absolutely get that it's necessary for some but what percentage of the Teensy user base needs such speed? What cost in terms of ecosystem...

Great! Thanks very much for your help, tni. For anyone else that stumbles upon this: for Teensy 3.2, the interrupt numbers for the interrupts on the digital pins correspond to their pin numbers (e.g. digital pin 3 has interrupt 3); the interrupt status flags for interrupts 3 and 4 are in...

Thanks for your reply, tni, but I believe that's not always going to be the case. I read in another thread between doughboy and Paul that the external interrupt status flag is cleared by "system" code before the "user" code is executed in the ISR. So, it is possible for the interrupt status flag...

Hi. I'm trying to port some code I wrote for an Arduino Mega2560 (in the Arduino IDE) to a Teensy 3.2 (using Teensyduino) but I'm stuck on how to do the Teensy equivalent of this line that clears the external interrupt's status flag: EIFR=bit(INTF5) // INTF5 is the bit in EIFR relating to...
