Re: RTOS question

Julie,

I found the resources of FreeRTOS invaluable in answering my questions regarding its implementation with the Arduino port of the ESP32.

Re: USBComposite, Some help making a gaming HID...

HID is not just for keyboards and joysticks, one can also do serious data-logging, too: https://www.hackster.io/rayburne/rpi-data-logging-using-usb-hid https://www.hackster.io/rayburne/arduino-to-excel-using-v-usb https://www.hackster.io/rayburne/analog-digital-port-viewer-usb Or, a clone of Adafrui...

Re: Teensy 3.0 to STM32f 103

Thanks So there is no simple way to fix it ? Yes, throw money at it ... Teensys are relatively inexpensive: https://www.pjrc.com/teensy/ Just as the Arduino.cc boards have certain advantages that warrant their pricing, the Teensy family is the same. Generally speaking, the same issues of compatibil...

Re: Designating variables to backup SRAM (LibMaple)

The backup registers are not the same as the 4KB of backup SRAM. I am asking if there is a way to assign variables to that specific 4KB area of SRAM that is maintained during STOP sleep. Maybe the F4 methodology will assist in tracking down the sequences... http://www.chibios.com/forum/viewtopic.ph...

Re: TS100 Digital Portable Soldering Iron...

:shock: > $50 U.S.D. We cheap-ass old folks buy: https://www.aliexpress.com/item/DC-12V-3S-XT60-RC-Battery-6W-Electric-Soldering-Iron-1min-Solder-Repair-Tool-For-RC/32843301801.html It is a specialty item, worth the price if used daily, but for the occasional use, the cheap on works just fine. Ray

Re: Google Groups !stm32duino

I seem to remember that after I logged in, I edited my options to not send mail notifications; which means it is a user-by-user setting and not global.

Re: Site will be read only from Saturday 27th April

Guys I don't necessarily think my core is completely dead. I just don't have time to check all the PR's or solve all the issues. ... Respectfully, "The core needs to be locked-down for 'Master branch' ASAP", IMO. Then, Roger, you can pick/create a branch to continue to be your own to continue to be...

Re: USBComposite, Some help making a gaming HID...

Have you go through the post: http://stm32duinoforum.com/forum/viewtopic.php?f=19&t=4046

It has been years since I have done anything with HID, so long ago it was an 8-bit AVR... But, as I remember, it all distills down to keycode combinations.
