[ProMini] Blue LED on Pin 13 wont turn off
-
@rollercontainer - could be, some bootloaders use this led to indicare its ready.
Arduino Pro Mini bootloader for example blinks if its loaded and waiting for a sketch to be uploaded. Depends on which bootloader you use and how that is coded.
But once you upload a sketch on the original bootloader it does not blink (unless there is radio traffic - ie signals going to and from the nrf24l01+ on pin 13.@sundberg84 Thanks a lot for opening my eyes!
I moved the radio to soft spi and now it works like intended.
#define MY_DEBUG #define MY_RADIO_NRF24 // RobotDyn Pro Mini 3,3V 8Mhz has blue LED on Pin13 which is used by radio and will be lit all the time. // Therfore, I moved the radio as it is done for the ethernet gateway. #define MY_SOFTSPI #define MY_SOFT_SPI_SCK_PIN 14 // Analog 0 #define MY_SOFT_SPI_MOSI_PIN 15 // Analog 1 #define MY_SOFT_SPI_MISO_PIN 16 // Analog 2 #define MY_RF24_CE_PIN 5 #define MY_RF24_CS_PIN 6 #define SKETCH_NAME __FILENAME__ #define SKETCH_DATE __DATE__ #define MY_NODE_ID 70 #define MY_PARENT_NODE_ID 0 #define MY_REPEATER_FEATURE false -
And you opened my eyes with the soft-spi remark. I just realized this could be an option to connect a LCD to a pro-mini as some kind of temperature indicator for multiple sensors. This is still on my wish-list.
- outside temperature (low, high, current).
- multiple room temperatures
- etc..

How about an I2C Display? Two wires on A4 &A5...

Going OT now - but @boozz here is an example of my i2c lcd (A4 + A5).

no problem, my fault was solved. Feel free to capture the thread ^^

Excellent question. I dont know.

Here are some scientific messurements: http://cc.oulu.fi/~kmikhayl/site-assets/pdfs/2012_NTMS.pdf
Table on last page says: SoftSPI consumes about double the electricity of a Hardware SPI on a PIC system. So, desoldering the LED is the thing to do.
Thx for the hint.
