I use the following code to create critical section. Is it correct?I use the __get_PRIMASK() and __set_PRIMASK(primask_bit) from exemple codes. Why are they needed? Why disable is not sufficient?Must I enable the IRQ after or is it done in the __set_...
Hello,I'm hoping to get clarification on the dual-bank flash availability in STM32G47x parts with fewer than 512K of FLASH. The datasheets (DS12288 & DS12712) cover the B, C and E flash sizes. The first page refers to "up to 512KB Flash", yet there...
Hello all, i have a problem with the STMTOUCH_DRIVER to manage a touch button and a slider. I have integrated the library into my code and if i manage only one bank and the touch button all works. In Touch.c and .h there is the init and main function...
I'm trying to get the ADC set up on the IoT discovery board. I did this successfully on the F411 so I thought it would be easy to move the code over, but I can't get it working.I'm trying to use PC0. The conversion is always returning 334 or 335, reg...

On page 92, table 7 contains flash memory addresses and their sizes.For every address range, the difference between the start and end address is 0x7FF, i.e. 2 KiB.However, for Page 127 in both Bank 1 and Bank 2, the range is listed to be 0xFFF, i.e. ...
Hello,I have tried to set the brightness of the blue LED on the STM32F0DISCOVERY via TIM3, not using the HAL or LL driver, but writing the appropriate registers directly, with no sucess.The peripheral register view shows that any write to GPIOC_AFRH ...
