I have a thermistor hooked up to the nucleo-l432kc to obtain temperature and display that temp on an LCD, print it to the screen, and light up a specific colour of an RGB LED. I want to be able to combine two colours of an RGB LED in different amount...

I have a thermistor attached to the nucleo-l432kc board and a C program that obtains the temperature and prints it on a terminal display, an LCD display, and lights up a corresponding colour of an RGB LED. I initially had my LCD set up to 3.3V (becau...

Hi all, I am currently writing a program that uses the STM32L432KC board (nucleol432kc) and a thermistor to obtain a temperature and then display that temperature on an LCD, a terminal screen, as well as turn an RGB LED on with different temperature ...

So I have it working with no flickering with the prescaler at 100 (just from trial and error, I might still lower it) and with the auto-reload at 255 still. Now to find a colour combo that looks correct on this RGB LED. Thanks a bunch!!!

I have prescaler as 984-1 and auto-reload as 255-1 (based on this tutorial and the fact that the clock is set to 64 MHz https://www.youtube.com/watch?v=KRhctlCOBOg). Also thank you for your replies!

Where do I do that? The only freq I can see/change is in the clock configuration, and there it says 80MHz is the max value.

I got it to work with PWM, however, whenever I try to make new colours out of combos of RGB, there is a ton of flickering that happens. Basically, whenever the value is not 255, there is flickering. This is some of the code:void set_rgb (int red, int...

Thanks for the reply! I am not sure how to do the latter of your suggestions, but for using the timer channels on PA8-PA10, the only one that is available is for PA8 and it is PWM Generation CH1N (all other options have conflicts), PA9 and PA10 only ...

Is it possible to mix different amounts of colours in an RGB LED using HAL_GPIO_WritePin pinSet, as in WITHOUT using PWM?

Having an issue with using nucleo-l432kc, MCP9700A thermistor, and an HD44780 LCD where once program runs first loop the incorrect temp displays (~2-3 degrees C less than actual temp) then it evens out by the 2nd or 3rd output.

I am wondering how to use PWM to adjust colours for an RGB LED if the LED is already set as a GPIO_Output? (so I cannot also set them as a timer(s)).
