There was a DMA issue I had where I had to disable/reenable a DMA channel to get it to load a timer edge capture correctly. I needed an interrupt to do this, so if it wasn't for the fact that I was capturing a burst of edges spaced ~100ns apart, then it would have somewhat defeated the purpose of using DMA in the first place. Also the RTC generator is/was daft. It would reload a hard-coded time value on reboot with no option to disable this from being generated.<br></div><div dir="ltr"><br></div><div>Cheers</div><div><br></div><div>Mikael<br></div></div><br><div class="gmail_quote"><div dir="ltr">On Wed, Sep 12, 2018 at 10:27 PM Mark Atherton <<a href="mailto:markaren1@xtra.co.nz">markaren1@xtra.co.nz</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">Hello all,<br>
<br>
Does anyone have any experience with the various toolchains out there <br>
for the STM32 ?<br>
<br>
Most of the stuff I do is bare-metal, but am definitely not a fan of <br>
stm32cube, or Eclipse.<br>
<br>
Obvious choices seem to be Keil uVison; the limited code-size trial IDE <br>
seems to be excellent. but looks like $$$$ is involved for the <br>
professional unlimited versions. I understand that ARM bought Keil a <br>
while ago, and that this product is their tool of choice.<br>
<br>
ARM do have a free toolchain gcc-arm-none-eabi (85MB) available, which <br>
seems odd given the conflict of interest with Keil.<br>
<br>
openSTM32 (owned by ac6) have an open source 'System Workbench for <br>
STM32' which seems bulky (!) at over 450MB.<br>
<br>
Finally, at least the older uVision toolchain appears to allow GCC tools <br>
to be installed. Anyone used this combination, if there is no code limit <br>
size on their debugger, this would be ideal.<br>
<br>
Comments, thoughts and experiences please.<br>
<br>
Thanks,<br>
