STM32F405 - ADC Result Not Reaching Full Scale
Hello, I'm using the STM32F405RGT6 to continuously read 4 ADC channels with 12-bit resolution. The problem is that the results the ADC is giving seemed non-linear, as you can see in the Excel file attached, where I tested it by injecting voltage from...
Placing STM32L433 into standby
Hi I am using the STM32L433 in a battery product and need long battery life. I am using standby mode as I need to preserve RAM and the RTC during standby. We are testing a new blank board and adding components one at a time and measuring the current...
STM32H753 and RTC return wrong day
In my project I want to use RTC on STM32H753 chip. And when reading the date, I get the wrong data in the position of days. And I can't fix this problem. When I debug, the registers are set successfully. :face_with_rolling_eyes: Init function: vo...
Resolved! static declaration of 'MX_FDCAN1_Init' follows non-static declaration - NO IT DOESNT!
I got an error, that is actually not true (see pictures). I just used cubemx to change one pin... And now this.
STM32H7 has a FMAC, can it be tweaked to implement FFT?
STM32H7 has a FMAC (Filter mathematical accelerator), and FFT also build on multiply-accumulation operations similar to the filters. So, can the FMAC be tweaked to implement FFT with minimum MCU intervention. And also FFT calculation with M7 core wi...
STM32H747 DISCO Development Board Communication between DSP and PC
I am working on a pathological voice assessor device, using the STM32H747-DISCO development board. I’m a new user and need some help with configuring and sending data from the DSP to PC - there is also a separate connection for debugging from my Macb...
Resolved! CAN frame monitoring problem in loopback mode
@SofLit hello again, So , i am facing a problem to display the frame i am supposed to send from CAN_Tx pin in loopback mode. I am using picoscope to display. Here is the function i wrote to configure the Header, and send the data: void CAN_send(v...
Resolved! Issue with CAN in loopback mode
Hello, i am using f446re nucleo board and have been facing a problem for a while now. I need to establish a loopback CAN transmission and the debug mode allows me to find a bug in the CAN Start function: HAL_ERROR 0x1 returned everytime i attempt. he...
Resolved! A bit disappointed about the STM32H7R/S lines
Dear ST,I was pleased to hear about the new STM32H7R/S lines, especially with the new graphic acceleration features in the R-line.However, and perhaps I have missed something, but I have to admit I am also disappointed about the absence of large size...
