Hey guys,I have expereinced a very strange behaviour of my STM32F429ZIT6 custom board:When I execute the following code the processor behaves differently in free running then in manual stepped mode or my oscilloscope seems to be completely broken - w...
Dual Bank Flash
HelloI would like to know if all STM32 cards have dual bank flash mode.I have two cards, a STM32F746 Discovery and a STM32L475 Discovery. Apparently the STM32L475 has mode but not the STM32F746.Is that right?If a card does not have a mode, is there a...
Multi-Channel ADC and I2C
I'm using an IMU 9250 (who works with I2C) and I need use at least 4 ADC single-ended channels. but, unfortunately, I'm not able to accomplish it. When the STM32f303k8 has the code (i2c + 4 channel ADC with DMA) and the 4 ADC pins are not physically ...
STM32L476 nucleo and Truestudio , how to force Truestudio to use the FPU?
Hello,I have the following basic code calls every 20msec. double test = 2.80009; TESTA11_ON; for (i=0; i < 500; i++) { test *= test; } TESTA11_OFF;When I compile and link with or without the FPU I always have the sam...
Why is this code not being able to change the default SPI value of 0 to 1, and also the bit shift on timer is not working

On the STM32F777 I am trying to determine if there is a readable silicon revision level.
I realize that I can read the ID Code Register at 0xE0042000, but I am not sure how the silicon revision is indicated for a specific device. Is it readable though the codes on the device itself?
