which controller with 12+ bits adc...

Using Arduino Microcontrollers
#1

Hello,
looking for a microcontroller with following features

  1. ADCs with 12 (minimum) or 14 or more bits.
  2. UARTS 2 (minimum) + 1 used for USB.
  3. Code upload through arduino IDE
  4. Could be nice if has some (<1kb) EEPROM

No problem on ram, speed, …
Any ideas?

thank you

Arduino Due.

Due is just okay. The ADC stinks and that’s being nice. Besides, its discontinued and the library support is awful.

IMO, your best choice would be a Teensy from PJRC. Teensy USB Development Board

If you need 5 volt digital compatibility, the Teensy 3.2 might be the best compromise, which is poor word to use since the 3.2 can run circles around any AVR without breaking a sweat.

Here’s the complete line technical details:

Look at the MSP 432 Launchpad from TI + Energia.

An Arduino DUE fits all your requirements, except the EEPROM. Although you can store variables to restore after power down with the DueFlashStorage Library (stores in the 512 KB of Flash).

Direct register programming for ADC conversion (12_bit ADC) is definitely the best option. Several example sketches can be found in the DUE sub forum of the Arduino forum. This board has 5 Serials plus one SerialUSB.

You can buy the brand new version of the Arduino DUE from arduino.cc:

Do you know anything we don't know? Where did you find the information that it's discontinued?

ok,
At a first glance the weight is on teensy. On the other hand, perhaps the more digital outputs and the DACs go on favor of DUE (future use, other projects-same platform).
I believe I have to read some things about .

thank you ALL

bye
