What does "Bit-Band Operation of Different Data sizes" mean?

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.

hcan1 not working while hcan2 does work with same settings

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 ...

Is there a way to detect if running on a STM32f103VC as opposed to a STM32F101VC.

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.

STM32H562 - application note/out of box example for SAI with PDM mic

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...

How do I check the MMC or SD cards before the card identification process in STM32?

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...

CAN bus not responding at 1Mbps bit rate

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.

consult the behavior of STM32L4S when error flag OPTVERR is set

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...

My product should have a lifetime of 10 years. So using STM32F107RCT7 chipset will meet my requirement? Also planning to procure the EVB module STM3210C-EVAL, but it shows obsolete in your website. Kindly suggest me on the availability or any alternate.

Nucleo-G070RB prints garbage via UART

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...
