Re: Analog Pin Numbering

<...> IMO, No newbies, no growth in the number of advanced users. And when the older farts like you and me die off, then what? Steve. Interesting response. Honestly, the Arduino.cc forum caters to newbies and 32-bit programming using official boards, such as Due. This forum was born from one very l...

Re: Analog Pin Numbering

<...> Would it be possible to add some "official" A# style defines for the Maple? (which has shield headers) Would it be wise to add some "official" A# style defines for the BluePill? (which has a consistent pin layout) It would also mean that the new BluePill Adapter board will...

Re: ADC ENOB low value.

The "original" Maple boards were 4 layer boards, with a separate analog ground plane. As mentioned earlier, in the cheap-o boards, the analog reference is tied to Vcc which is 3.3'ish Volts. Looking at the running STM32F103 Vcc to ground with a scope, there is lots of noise present. Likely...

Re: Using STM4ARDUINO for commercial code development

Recently Texas TIVA C based MCU using their IDE which is quite similar to Arduino. Till now i doesn't used it, But when i saw the overall functionality and support side for it. Its found quite time saver and interesting. We can also put effort together to make powerful stuff like that which is able...

Re: Using STM4ARDUINO for commercial code development

Currently I am using Atollic Truestudio for code development. But its find little bit difficult to me. Earlier i done lot of stuff with Arduino IDE and its perfect for me. Now i am using stm4arduino (Great Work by Roger Clark) for commercial development. Some libraries are unstable. I am facing som...

Re: New RPi Zero W - with Wifi and Bluetooth

The specs on ESP32 are amazing. I've been playing with the dev module under Arduino for a little over a week; My BIG surprise is SPIFFS is not implemented; so if you were fond of SPIFFS for storage, it appears that support will come at some time (maybe.) https://www.esp32.com/viewtopic.php?t=239 Th...

Re: $10 O-Scope revisited

the noise, yes, by small signals. but I think a Scope is more for the signal form etc, not for the accuracy ( if the amplitude is 2.5V or 2.516 V) . Yes, in the "old days", scopes were analog and had a 1V p-p internal reference so the user could calibrate/verify the probe and front-end wi...

Re: ST-LINK V2-1 does not work with Windows 10

Thanks. <...> I use 4 computers, all Win 10 64 bit, and the same development softwares. Newest Stlink driver and newest firmware. Same Avast antivirus on all. First one: Stlink V2-1 is never usable. Shows up in device manager, but none of the softwares can use it. Stlink V2 work fine. Second and th...
