Encoder mode counter division possibilities?

Now every rising and fall edge are counted which results in counter incrementing by 4. I see and have tried playing with Prescaler Division Ratio which should normally be the parameter to divide incremental number but it does not work on Encoder mode...

STM32F746DISCO, WIN11, GFX,

How to understand the sacle factor of stm32g4 cordic algorithm? For example,i use the cordic algorithm to calculate Arctangent,but i don't understand why ARG1 is x*2^-n, RES1 is 2^-n *tan^-1 x .I think the correct result is tan^-1(x*2^-n),

Problem Sending CAN Message

Posted on April 15, 2018 at 23:27I am following the example code found here to send and receive CAN messages:STM32Cube_FW_F4_V1.21.0\Projects\STM324xG_EVAL\Examples\CAN\CAN_Networking\SrcI can happily receive CAN messages but when I call the followi...

Flash Erase without interrupting the ruining application for updating the firmware over UART

Hi Team,System Overview:- We have a system which contains two controller, out of which one is STM32G071. Second controller handles all the wireless operations i.e. Wi-Fi. both the controller communicate over UART to exchange information. Data receive...

Hi, We are using STM32F427IIH7 for one of our project and it is out of stock now. we found an alternate part(STM32F765IIK6) for that but the new part have some additional features like VDDSDMMC and VDDUSB . Also found some diff on PDDR_ON connection.

I can't receive the required ack bit from N2 node. So CAN message can't be transmit from N1 node.

As you can see due to i can't receive the required ack from N2 node, N1 node It keeps sending the same message. Then HAL_ADDTX function returns HAL_CAN_ERROR_PARAM because the transmission is not happening and all mailboxes are full. Also i request T...

input configured pin to detect frequency.

I am using STM32F103C8, in which I want to use pins which are configured as digital input to detect the square wave frequency or the frequency at which the pin is reading high and low.Is it possible without Input capture direct mode?
