I was looking at the wrong thing:-(<br /> Thank you!<br /> It looks like a minimal STM32F103 USB Serial is just over 10KB which is plenty small enough.<br /> I'm making mistakes - time for sleep. </p> http://forums.leaflabs.com/topic.php?id=74185#post-105019 Fri, 06 Dec 2013 18:06:46 +0000 mlundinse 105019@http://forums.leaflabs.com/ <p>I have looked quite closely at the Serial USB code for the standard Maple.<br /> It is quite minimal as it is presently. You might be able to squeeze a few bytes out<br /> of it, but then it needs careful re-testing, and the current code for sure doesnt use a lot of extra bytes.</p> <p>I am aware that design choises can always be argued and changed but then the tradeoff<br /> between a tested and an untested solution must also be made. </p> http://forums.leaflabs.com/topic.php?id=74185#post-105018 Fri, 06 Dec 2013 17:42:14 +0000 gbulmer 105018@http://forums.leaflabs.com/ <p>I want to make a little gizmo, with no more than a couple of KBytes of specific code. I'd like it to be a USB serial device.<br /> I'd like to squish everything into the lowest-cost 16 kB Flash STM32F103.</p> <p>Has anyone experience with, or done any experiments to find the smallest practical size for USB serial device code on an STM32F103? </p>
