STM32H753 vs STM32H23 radiation tolerance

We plan to use a STM32H723 for our main MCU on board a student CubeSat.We are currently verifying if this is a feasible option. I came across this report by the Open Source Satellite Project testing radiation effects on the STM32H753.As they are from...

convert 10-bit data uint10_t to float

i m using STM32H7 SPI to interface to external 10-bit ADC, which return a 16-bit data but only the last 10 bit (from LSB) is valid. How can i convert this 10-bit data to float ? and how can i obtain these 10-bit from the 16 bit data, i know i would n...

I2C Slave hangs on low SCL signal

Posted on May 08, 2018 at 08:45Hello guys,I use the STM32F030R8 as I2C slave with clock stretching. It is able to receive and send data based on interrupts. The transmission of the slave to the master works as long as the master and the slave know t...

Resolved! STM32 Flash Write fail

Due to engineering requirements, the code is divided into two parts: USB DFU, including encrypted signature verification, and the APP code with header signature file. Currently, there is an attempt to rewrite the flash in the USB DFU orange section f...

Resolved! VREFBUF and STM32H563VI

I have VREFBUF configured for output to comparator on my board. I see this on MCU Vref+ pin...Is 1.2MHz waveform typical? Are capacitors on Vref+ expected to smooth? I looked for avg closer to 2.5v (VREFBUF_VOLTAGE_SCALE0). How close to 2.5v should t...

is there a need for early initialization, SystemInit ?

So the startup code first sets the stack pointer, and then jumps to SystemInit for early initialization, then copies the initial values of data and zeroes bss region and then kickstarts C startup. Is there anything hardware related that has to be don...
