Resolved! A usable and minimal USB osciloscope with bluepill
hi guys, I'm a desktop programmer and do not know much about micro controllers and electronics but i am very interested in making an oscilloscope which:- simple to build with well known parts and ICs- it uses bluepill as the ADC and no other ADCs- i...
Resolved! Accurate ADC reading with Bluepill
Hello all,for my DIY Radio Controller (LoRa and STM32F1C8) i am using two joysticks and one poti.I am reading ADC with the DMA but what i noticed is that the ADC values are not so accurate.I know with not (professional, expensive) Potis and joysticks...
Resolved! STM32L552CCT6 Unable to erase flash memory
I can't erase the flash in the STM32L552CCT6 with the code below. I wonder if my code is wrong. When I check the memory, the 2kB from the flash address 0x803F800 is not 0xFF. The reason it wasn't 0xFF originally seems to be because something other th...
Input bias current of comparator inside 48 pin STM32L073 microcontroller
Hi,We have a 1MEG resistive divider which we hope to provide the reference to the comparator internal to the STM32L073.Though we need to know the input bias current of the comparators inside this micro in order that we can calculate the volt drop by ...
Resolved! Too high current draw in shutdown mode
I'm just getting started with my STM32WB15CC nucleo board, and my first goal was to put in shutdown mode to check the current draw, which I expected to be around 1 uA. I'm measuring the current on the JP3 header with a joulescope which should represe...
STM32G4 Interrupt Enables I2C
Is it necessary to enable interrupts in I2C_CR1 if I only want to look at the flags but don't want to go into the interrupt service routine? For instance, I want to be able to look at the status of RXNE and see if it is set, but I don't actually want...
Resolved! What is the actual STM32 pin capacitance (for the purpose of sizing an HSE crystal)?
Hello,I originally tagged onto this thread: https://community.st.com/t5/stm32-mcus-products/stm32f103-hse-crystal-capacitors/td-p/771200 but I was recommended to make a separate thread. Many of the STM32 datasheets, such as the STM32H753, say that th...

Hello Which are the correct Capacitors to use for HSE on STM32F103 with the following Crystal?Frequency: 8 MHzLoad capacitance CL: 20 pF Thank you in advance for a quick hint.RegardsMichael
Resolved! Crystals and load capacitors for stm32l432
Posted on July 10, 2018 at 14:37I've been designing sub-gram boards for data logging on songbirds using the stm32l432. Although mostly I use ultra-low power external RTCs, I recently built a test board using a 4pf 32768 crystal. The question was t...
