Resolved! STM32G0: Remapping address 0x00000000 to SRAM does not work
Hello,I'm using a STM32G0B1CC and I'm trying to remap address 0x00000000 to SRAM like this: __HAL_RCC_SYSCFG_CLK_ENABLE(); __HAL_SYSCFG_REMAPMEMORY_SRAM();Unfortunately this does not work and 0x00000000 is still mapped to FLASH.If I try to remap t...
Resolved! How to generate PWM and use timer interrupt at the same time?
I am using the Bluepill board. I want to generate PWM signal on Timer2 and set up a timer interrupt at 20ms interval on Timer3. I realized that the PWM signal cannot be generated if I set up the timer interrupt on Timer3. How do I solve this problem?
How to prevent uploading a new sketch to a Nucleo board
I hope this thread is posted in the right category.I’ve been using Arduino boards for several years and am thinking of using a Nucleo 144 board (specifically, Nucleo-F207ZG) for a project. Once the project is completed, it will be serve as a permane...
Determining RAM size at Runtime?
There's the Flash Size Register in the Device electronic signature. Is there an equivalent for the onboard SRAM size? Any way to get the ACTUAL SRAM size at runtime?
Resolved! ADC(with DMA) doesn't work when I increase its frequency
This has been a reoccurring issue for me, whenever I raise the ADC frequency above 0.25MHZ the while loop gets interrupted, and when I use frequencies below that the ADC resolution drops to 8 bits for an unknown reason. Is there a way to fix this wi...
