Arduino for STM32

Im having real trouble getting this working on my project. Its really strange that at one point I got one of the tasks working, but then it stopped and never worked again. Even though nothing has really changed. When i call xTaskCreate the program hangs. TaskHandle_t checkButtons =NULL; is in global...

According to the reference manual (see RM0008 page 318 text above figure 84), setting the compare value (pwmWrite()) to a higher value than the reload/update value will keep the output pin high. So yes, if you setOverflow() to 65534 and pwmWrite() to 65535, this should match your requirement. P.S. ...

So setting the serOverflow, to 65534 will keep the PIN high with no dip at the top duty cycle?

This behavior is normal according to the reference manual. There are two ways to solve your issue: 1 - your workaround 2 - choose an update value of 65535 for the timers. In this case, when the compare value is greater than or equal the update value, the output will be a clean "1", withou...

Good news bad news........ Good news, got the chip talking by having the pullups hacked into a scratched off bit of trace near the chip... Bad news. I have no choice but to do a PCB respin now.... Sighs. Well im not going to get this to the guy before Christmas :/ And its yet another bit of wasted m...

They scope the same. But because its such a small amount and theyre not red, thats why they dont light up. I also could manually latch on by reducing the time scale... https://i.imgur.com/JMMd7MD.jpg This seems to be happening at the end of each pwm cycle. the PWM control is in the setup portion of ...

Deffo 5B, but i wrote a sketch to check each address one after the other, and say if theres no response.
I also checked my old build version, and i used a 10k pullup on that address too...

I just hacked on some 10k pullups on the i2c pins, on the mcu side of the circuit as i could solder to them.....

And still not working :/

And while my scope doesnt have logic analysing... Its not really picking up much of anything, there might be a single drop pulse but no data going across

Cries, thats gonna mean needing to do YET another pcb spin D:
If i cant use internal pullups

See https://github.com/stm32duino/wiki/wiki/API#i2C . ... Redefine I2C pins Because they are defined as WEAK, you can redefine them in your sketch file instead of changing values in the PeripheralPins.c file. You can also enable/disable the internal pull-ups with the second parameter of STM_PIN_DAT...
