Resolved! Trouble with ST-LINK/V2 debugger

I'm feeling really stupid about this. We were unable to debug in our circuit, so to check, we have a standalone STM32L021D4Px, mounted to a solderless breadboard. 3.3V is connected to Pin 14, ground to pins 9 and 1, NRST to pin 4, SWDIO to pin 13 and...

HAL_SPI_Receive() Pins not doing anything.

Hi, I'm new to this environment. I try never to ask questions on forums but I've been stuck for over a week. I set up a blue pill board and tried a simple SPI setup of a single 74HC595 and a single 74HC165. I got the 595 working great with this code....
