How to do PWM capture on xcore.ai board ?
Dear Community, Is it possible to do accurate PWM capture with the xcore.ai evaluation board ? Presently I'm doing it with timers on a STM32 H723ZG board but I would like to off-load this task to free the timers for other tasks. (& transmitting the measurements via SPI to the STM32 board) The pu...

XCORE.AI availability ?
Hello, Does anybody know when the new xcore.ai should be available ? Eval/Demo boards ? I sometimes check xmos web site but it is always the same material since a very long time now. It looks promising but where is the silicone ? I registered long time ago to the "alpha programme" but neve...

Re: broken startKIT - first stage multi-node boot failed
Thank you for your time. The second_dump is 100% full of 0xff especially the start of the 262144 bytes file, so the erasing works. But I have more and more difficulties to get xflash working, it is now stalling in erasing for more than 15 minutes ! The 2 first erases worked and I could relaunch 3 ti...

Re: Which circuit is better for my ATtiny13a mcu setup?
Why don't you use any off-the-shelf buck-boost regulator ? You could also then connect your circuit to batteries like 1 cell LiIon, 2 cells NiMH, etc, I use them a lot for this kind of job (+ with a cell discharge protection circuit) https://www.amazon.com/Adafruit-VERTER-5V-USB-Buck-Boost/dp/B00XW2...

Re: Standard UART Library - How to get more than one char ?
I'm living a nightmare, the above code worked fine during one day (=I was able to receive more than 1 char in 'cmd[]' and then parse them in 'parse_cmd(...)' but since today, the *exact same code* is only able to receive 1 char, I'm sure at 100% I'm running the same code - I did a zipped backup of t...

Re: broken startKIT - first stage multi-node boot failed
Hello mon2, I tried your recipe but xflash refuses the target "name" (tried '0', 'L', L0', 'L[0]', 'startKIT', etc.) So, I still need this pin 1 voltage + usb disconnect - reconnect to be able to run a new program... Tried on 2 different workstations, I'm now on Linux with the problem stil...

Re: Standard UART Library - How to get more than one char ?
Thanks, I will investigate moveable pointers - I managed to make it working with interface but it requires to copy the data (in 'command[]')- ok for small arrays but for bigger things, it is cpu time & energy wasted. typedef interface my_interface { [[clears_notification]] int clear_notification...

Re: Standard UART Library - How to get more than one char ?
Thanks for the info, i finaly have this code running but now I'm facing the problem of how to dispatch the received char of char to the other tasks... I tried the chanelend master-slave-transaction without success, it seems we cannot use the ':>' and '<:' operators inside a 'select-case' ? (makes my...
