STM32L051K6U6 comp1 can not be used？
Posted on October 10, 2017 at 05:27I configured comp1 with stm32cubemx, but I can not configure the COMP1 register, using COMP1-> CSR = 0x11; the value of COMP1_CSR is still zero.WHY？

STM32L151VE ADC in sequence reads higher value for the 1st rank
ADC consistently reads higher value for any channel which is 1st in the sequence. If I query this channel 2nd time as rank 2 (immediately after high value) then it reads normal value. Value is high by about 10%.Tested on stable input many-many times....
Resolved! STM32L151VE ADC reads 20% lower value on one of the ADC inputs (channel 18, pin B12)
Not sure if I messed something up. Signal is okay (on the pin). No differences with layout compared to other inputs. ADC is at full speed (16 MHz).On image it is sensor 22 (reads ~2500). Sensor 23, 24, 25 all read normal values (~3000).Voltages on al...

Strange padding in the .data section of the .elf file
I'm currently writing a program on STM32F411 that uses a simple bootloader and two sub-applications. The sub-applications are located in the flash memory and the bootloader loads one of them (both code and data) into the RAM memory and then starts ex...
I would like to do an absolute minimum bare bones project. Could someone direct me to a C project that just shows how to make a port input or output, and how to toggle the port high and low?
I've got a MCBSTM32F400 development board. Every "getting started" thing I've found (blinky, for example) has like 900 files in the project, and 150,000 lines of code. This is so disheartening. I got into microcontrollers because of their simplici...
Connecting DAC to OPAMP in STM32F303K8
I'm curious if there is any way to configure the STM32F303K8 such that the OPAMP is driven by an internal signal, preferably one of the DACs.I'd like to use it as a headphone amplifier or an amplifier for a tiny speaker, but not sure if it's appropri...
Does the ADC conversion time need to be shorter than the timer interrupt if the ADC is driven by a timer interrupt?
I am driving ADC1 using the timer interrupt from TIM2. At the moment it is only converting one channel at certain intervals. The ADC is set up with the following:ABP2 peripheral clock = 84 MHzPCLK2 divided by 8Timer 2 trigger out event as sourceSampl...
