STM32L451 and PC13/14/15 in SHUTDOWN Mode

Documentation is a bit vague with respect to use of PC13/14/15 as GPIO while MCU is in SHUTDOWN mode. My understanding is that these pins can be used in the backup domain (my VBAT is connected directly to VDD).I understand that I could SINK up to 3mA...

Best practice to modifying DMA accessed memory?

Hello,I have a general question about DMA which I am currently using to transfer a LUT in the memory to control PWM output.The LUT changes periodically and at the moment the DMA is triggered with a timer. What I would like to know if it is safe to ch...

Resolved! Can DMA CR TCIE bit be changed, when DMA is enabled?

Hello.I'm testing ADC with DMA on STM32G071. I wanted to have interrupt on transfer complete, but I had trouble clearing TCIF flag in ICFR register. Even if I cleared the bit, ISR was entered again immediately. I don't have circular mode set neither ...

D0-D3 lines always high on STM32F412RE

I'm trying to connect a ILI9341 based parallel LCD to STM32F412RE. I have successfully connected that to the STM32F412ZG in the past, but that was using the pins in the H/G ports not available in the 64 pin package. When configured for pins on the 64...

RADC of STM32G473

Figure 29 of the STM32G473 datasheet calls out an unspecified, internal RADC. Is there any data on this internal resistance?
