Hi, I am reading the book <<The Definitive Guide to the ARM Cortex-M3>>, and I see some descriptions below, but I really don't know what it really means. Could you explain it to me?Thanks very much.
I'm working with a custom STM32F105 board with two similar CAN circuits but CAN1 is not working.I use STM32 HAL with this custom CAN lib which handles configuration and buffering.It was working before with the same hardware but I can't get it woking ...
Customer has fitted both to different rev boards and wants to detect the hardware rev based on the processor type that was fitted. both run the same firmware without issue. I'm looking for a way (in firmware) to detect which processor is fitted.
At the moment, we evaluate feasibility of STM32H562 for our application. Our application is using PDM microphones. However, STM32H562 has SAI interfaces but no DFSDM filters.Is there any out of box application example /application note for PDM micro...
In the RM0090 Rev 19 document of the STM32, there is a card identification process explanation, The card identification process differs for MultiMediaCards and SD cards.It seems that the card identification process is different for MMC and SD, but si...
I'm using STM32F446RC controller CAN BUS 1. Trying to operate CAN BUS at 1mbps speed when using 100kbps bit rate it is working fine but not at 1Mbps bit rate. Is there any solution for this.
except the statement from RM0432-stm32l4: "OPTVERR will be set by hardware when the options read may not be the one configured by the user. If option haven’t been properly loaded, OPTVERR is set again after each system reset."There is another stateme...
I've programmed this board to print out some data via the onboard serial interface (using UART2). But all I get is garbage characters, and I can't figure out why. I checked the baud rate of both the Nucleo and the terminal, I've tried different termi...
As a newbie user, I tried to do basic code in STM32CubeIde which includes only potentiometer and leds. My goal is that when Potentiometre's value rise, different led will light. The code works but when I rise the potentiometre's value the leds don't ...
