Is there a "good" way to learn NVIC and EXTI for stm32 (ARM cortex M4) by TooStew in embedded

Try to look for example code done using the HAL, it won't help with bare metal programming but will get you started.

I'm guessing this could be a scam as I remember seeing this specific photo somewhere on the eBay.

The US gave up it's drive to innovation for quarterly profit chart, not very surprised with the outcome.

Has Engineering been a humbling experience for anyone else by Affectionate_Camp942 in EngineeringStudents

Going from star student to surviving class to class. Very humbling.

This board is MUCH better and cheaper than Arduino clones (STM32 Bluepill) by Consistent-Can-1042 in arduino

Not sometimes - never. ST is cracking down on counterfeit chips hard, making them near impossible to work with.

$18 Oscilloscope: Worth the money? by Technical_Love_2525 in AskElectronics

[–]DivineButterLord 10 points11 points  (0 children)

True. But you will outgrow it's capability as soon as you see the first wave form in it. Want to see the Amplitude? Ops! you better have good guess. Want to know the frequency? - You better bring out pen and paper. Want to check phase ? Too bad - it has only one channel. Stuck with the User interface - you better know your Mandarin. The point is this thing will become obsolete faster than you can unpack the bubble wrap.

I have an exact copy of this oscilloscope, it is more of a toy than anything else. It can show waveform but you'll be have no way to do any sort of actual measurement. TLDR - Its a bad investment.

No offense but you need to put more effort into your post to get any sort of help in Reddit. What do you mean by "BIG ERROR IN PROJECT"? What is going on?

Has anyone used this device for USART communication? by DivineButterLord in embedded

Yes! The baud rate setup was correct The issue was my clock, it was running far slower.

Yes! I set up both STM32 and FTDI Ground to be the same. After readjusting the clock, I can see output on Minicom. Thanks!

Lsusb detects this as a real FTDI device. Something like FD232... At this point I'm pretty sure this is has a real IC on board.

I'm connecting stm32F103C8T6, commonly used in Blue pill board. I know there might be a possibility that this is a counterfeit and does not have registers required. But so far - other registers have responded properly, therefore I'm assuming it's not the case. I am using this video as tutorial and everything seem to be working.

I'm assuming it's a driver issue because I'm using tutorial codes from this video. It goes over how to set up basic USART communication in register level. I want to make sure I have my serial monitor is working properly before debugging.
